What should I ask the "grandfather of the U.S. commercial seaweed industry"? As a researcher and pioneer of aquaculture, this ologist can tell us about the roles of seaweed, the methods and impacts of seaweed farming, and the latest studies on sustainability. But also: why is seaweed so slimy? Why is there so much seaweed on shore? What do you want to know about seaweed?

Deadline: Friday, May 2 at 5pm PST

Comments

Matt Ceccato

What kind of seaweed is edible?

RJ Doidge

Is it…actually a weed?

Jeffrey Bradshaw

Do they have flowers? Do underwater plants have flowers? How does that all work if they do have flowers?

Storm

why is it called seaWEED when it’s just ocean plants existing, it feels so hateful!!

Storm

why so smelly

Rayna

Seaweed vs Seagrass — do they serve different purposes or are they both the same?

Anna Thompson

Does it grow from the ocean floor up or from the surface down?

Anna Thompson

Is kelp the same thing as seaweed?

roni 💥

how do some species have air bladders in them? why are there balloon plants in the ocean???

Kevin Zimmerman

I heard feeding seaweed to cows can cut down on their methane output, is this a) true and b) actually happening?

Charlotte Parkinson

If you are addicted to seaweed, sea kelp. You're welcome and I am not sorry.

Darrah

Why can't I get more seaweed snacks and food everywhere? I love eating seaweed in every form and would eat more of it if it were available.

Keerat Singh

I’ve heard most of the seaweed off of the west coast of the US is edible. Is that true? Are they tasty?

Mykenzie King

I think so often about SpongeBob SquarePants’s seaweed mustache in the SpongeBob SquarePants major motion picture. But my actual question is are there different types of seaweeds species for different kinds of water (fresh, brackish, salt).

Meg

I remember always hearing growing up that toothpaste is (at least partially) made of seaweed! Is that true? If not, where did that rumor come from ??

Keerat Singh

Other than eating what do people use seaweed for?

Amesia Doles

I always want to forage seaweed, but is it all edible? And is there concern for consuming toxins that might be in the water or a way to check when it is safe to eat?

Stratford Abbott

How can I sustainably enjoy the fruits of the sea or sea weed and why is it so good for my skin or why do I think that kelp and seaweed based skin products are good for my skin.

Potato Puffer

What’s the deal with Sargassum? Why is it becoming invasive and why can’t it be eaten/utilized like other types of seaweed.

Chris Lipford

Is Red Tide a type of seaweed, or something that affects it? And why does it make me feel like I’m dying from three miles away?

biomermaid23

omg hi i am so thrilled about this !!!! i am a recent marine biology grad (BSc) and seaweed is just the absolute coolest. what is their favourite use of seaweed in their non science life, and what path did they take to get to be a seaweed farmer ! also curious to hear about the impacts and climate change reduction projections for kelp farming! 💚

Chris Lipford

That’s breaking my brain. I hope they answer this one! Piling on, if they do have flowers, is there an underwater equivalent to bees?

Emma Luck

Kelp farming is a growing industry in some areas, like Alaska, that also have substantial marine mammal populations—how can we reduce entanglement risks when constructing kelp farms?

Jordan Buell

Does seaweed produce oxygen?

Hannah E

Are all different types of seaweed edible for humans? Are there any types that are only edible with specific preparation or only to species other than humans? (1st time question asker who is eating their favorite snack, roasted seaweed, while typing)

goatleaf

Are there any psychoactive or pharmacologically unique compounds found in seaweed that are being studied?

Cooper Michael

When I was younger, I was roped into diving under water and pulling up seaweed at a beach on Lake Michigan… is there a better way of removing it AND what are the consequences of doing that for our own convenience?

CasualCatLady

How does the seaweed handle all of the extra salt from the water? What sea creatures use it to lay eggs on?

Diana Teeter

Does seaweed have seeds? How do you farm and get more of it?

Megan Morgan

How many types of seaweed are there? Can all seaweed be eaten, or is some toxic? If kelp is considered seaweed, are urchins still decimating it on the northwest shores? Do “kelp wraps” actually have any benefit for your skin? We don’t wrap our body in broccoli, but we do seaweed/kelp Is seaweed prevalence an indicator for the health of the surrounding ocean waters? How important is seaweed to the food chain, and will it be a serious disruption if seaweed becomes less abundant? How is climate change impacting seaweed prevalence? Are some areas seeing less seaweed than others? Is there anywhere in the world seaweed would not be found? I.e. thermal vents, Arctic Ocean, etc.

Abigail Bartell

What makes dulse edible and are other seaweeds edible?

Robin Kuehn

Not a question, but it would be a great opportunity to shout out Dr. Kathleen Drew-Baker, (1901-1957) revered in Japan for her contributions to science but dismissed from university when she had the audacity to marry.

Ben Beardiac Fiore

Do any seaweed varieties produce fruits like land plants do? Is seaweed even a plant or really complex algae? (First time question asker)

Angela Borman

Are all types of seaweed edible? What are the best tasting types?

Lauren Allegra

Is there funding to use seaweed farms to sequester carbon? Or is it currently just grown for commercial use?

Michael MacLeod

Is it true that seaweed is 50% sea and 50% weed?

Sarah king

How does it do with pollution?? If we are doing a lot of it for sustainability are we screwed if there is still so much pollution

Bronte

Tell us about its planet saving abilities please! And also why does it smell bad when it washes up on the beach. What depth of water does it like to grow in? And does it grow in all climates?

Brenna Hull

Is seaweed facing any climate threats, like coral? What can people do to help protect our sea-faring forests?

Tony Vessels

So, like.....what is nori? Why so tasty? Are there other types of edible seaweed?

Maisie Lopez

What are some ways to rid/use sargassum? I have heard of using it as a greener additive to concrete, are there any other innovations?

Kailey Bell

Brown seaweed contains a polymer called alginate that is widely used in biomedical applications! I once worked on a research project testing an alginate based patch for sealing lung punctures and some of my professors used alginate for other things like bioprinting and wound healing dressings! I’d imagine there’s some cool applications in other fields too :)

Adam Foote

What's the difference between seaweed and kelp?

Lizzy Martinez

What were the first known human interactions with seaweed? Like did they think it was a mythical creature's sign of being near?

Dr Laura M Smith

How do seaweed farms deal with runoff pollution and sediment from storms? Are there innovations to reduce waste in the industry, particularly plastic waste? How much stock is there in the superfood marketing that we see for seaweed products? Are there creatures that use seaweed farm areas as habitat? How do farming practices avoid impacting them?

Karol

How did seaweed end up in the water? Or did it start in the water, and other land plants came from aquatic environments?

Brenna Hull

What would happen if you dried and smoked seaweed? Get it? Sea-weed?

Dr Laura M Smith

Seaweed isn't a flowering plant but seagrass is!! So cool!

mish the fish

what's seaweed's dirty little secret? what dark thing about it are we all unaware of? cancel seaweed

Dr. Niki

I just wanted to say that my cat's name is seaweed. She only has one eye and she says hi!

Gabrielle G.

Many cultures include seaweed as a staple in their diet. Given that, what can be done to mitigate the potential dangers of heavy metal bioaccumulation in seaweed?

Joe Porfido

I have a seaweed tattoo because it's my favorite!

Erin Everton

How effective are IMTA operations that combine seaweed and shellfish? I feel like I don’t see so many of them but it seems like a great idea

Erin Everton

How different is seaweed from other submerged aquatic vegetation like eelgrass? Why don’t we cultivate eelgrass for food?

Alex Kim

How have seaweed cultivation techniques evolved over the centuries? Curious about various farming techniques that have developed foraging seaweed in the wild to large scale farming operations.

Jenny Lowe Rhodes

What is the difference between kelp and seaweed?

Sonjabird

Why is it that when you cook beans with kelp (or feed seaweed to cows) it reduces flatulence?

Pseudonym Jones IV

If you told me I would be eating all this seaweed when I was a child, I would have scoffed. And yet, here I am...

Meagan Walker

Well dang I just learned something!

Rachael Mae

Also curious about this!!

Sunflower star

Does commercial seaweed farming create habitats the way kelp forests do? If you are creating a seaweed farm what are your considerations regarding other species in the neighborhood, and what's the process to propagate, attach and cultivate them? Aside from bull kelp forest dwindling do other seaweeds serve as keystone species in other ecosystems or are there other majorly endangered species?

Meagan Walker

I’ve heard that seaweed isn’t actually a weed, it’s algae? Is it the biggest algae or are they made up of wee little algaes cooperating?

Rachael Mae

What types of seaweed are edible? Are ALL types of seaweed edible? What do different seaweed species taste like? Does this ologist have a favorite??

Meagan Walker

How do they breathe before they reach the surface?

Meagan Walker

Can you grow a freshwater seaweed? Could I cultivate some in my bathtub if I made it salty?

Rebecca Morrison

Why is it called seaweed? Also, are kelp forests helping the planet?

Danae DeJournett

Is all seaweed good to eat (what’s the difference between the two if so) and can you explain the origins of MSG and the racism surrounding its introduction to American cuisine?

Julie

Why does it taste like that?

Jessica Berghammer

I’ve heard seaweed is good for your thyroid? Is that true? If so how much should you eat?

Aurora Cullen

difference between seaweed and kelp?

Becky McDowell

How did seaweed evolve? (from my superfan 13-year old son:-)

Aurora Cullen

Is seaweed a sustainable industry due to the climate sequestration they do?

Nicky G

What other uses does seaweed/kelp have other than as a food source? I saw a video on social media that it can be manufacture to use as a clothing fiber...? What else can seaweed do?!?

The Little Butternut

So excited about this episode! Can seaweed save our food system? I'm so hopeful about it and I'm curious to know how we can better harness this growing (pun intended) food category and integrate it better into our regular diets.

Rose

What invasive species of seaweed are the worst environmentally at the moment and can we eat our problems away like knotweed?

Brenna Hull

Can we land mammals eat seaweed straight, or can we only tolerate it when it's dried or processed or used to make something, like ice cream?

Alice Rubin

Hos is cloth from seaweed made?

Jernelle

(First time question asker 😉) Tell me EVERYTHING about the research behind the application of seaweed in respect to neurodegenerative diseases like Alzheimer’s, Parkinson’s and Dementia!

Alice Rubin

why are kelp forests so amazing and why are they so underrated?

LightBrownPillow

What do we know about the evolution of seaweed? How long ago, first kinds, fossil records, etc.? Has seaweed been used to develop any major products we use in modern life? Medical, bioplastics, fabrics, oils, emulsifiers, etc.?

Jaqi McCarthy

Seaweed farms and shellfish farms are an excellent combo for sustainable foods! How can we encourage more people to eat sea vegetables? (P.S the book eat like a fish is amazing)

Alyssa Ranker

Ooh I didn't know cultivation has been ongoing (assuming for centuries) Please tell us which cultures have cultivated seaweed and for how long.

Alyssa Ranker

I hope there's a solution for the plastic waste. I used to love getting seaweed snacks as a treat but I realized how much packaging there is for so little seaweed.

Greg Walloch

Should we be eating it??? Is it helping us - "Anti-Inflammatory, lower cholesterol"? Or is it hurting us: "Full of heavy metals and disrupting thyroid function"? I'm confused.

the ren you know

Is most seaweed edible, but it depends on where you get it from? Like, if I harvest it in the open ocean vs washed up on a beach? P.S. my sisters and I named washed up bull kelp "Garflungas" (gar FLOON guhz) when we were kids and would drag them around by their 'tails' and name them...

Kiki’s Delivery Service

Why is the seaweed from the grocery store or on the menu so vibrantly green, when at the shore and underwater it looks yellowish or brown?

DeeDeeNoodle

Not a question, but need to share that I live in Australia on the sunshine coast and have been involved with the seaweed regeneration project via the 'seaweed team's at the local university of the sunshine coast and have had the pleasure of doing a dive course with them. Really looking forward to this episode and can direct you to their research if you want/need any!

Alyssa Ranker

Yes like what's the nutrient profile of seaweed? How much fiber?

Alyssa Ranker

What is the flavor profile that makes seaweed so yummy? It's like a naturally umami vegetable.

Erin Gunderson

I've noticed some seaweed listed as edible showing up in the aquarium trade. If it grows in a home reef aquarium tank, is there a reason it wouldn't be as edible as wild collected?

Emily Shaye

Do any other little sea critters hug onto it in stormy seas conditions like seahorses do with their cute curly tails?

Barchaeologist

Whats the deal with feeding it to livestock to reduce methane emissions? If it's true why isn't everyone doing it?

Megan Dawe

What gives it the slightly boingey texture when you chew it? Even dried seaweed seems to have this attribute to some extent, so it seems like it must be something structural.

Brenna Hull

I know I've had seaweed salad and dried seaweed, but ive never seen freshwater weeds (unless they are just marketed as seaweed?). I wonder if there's something about the salinity of the water that makes seaweed tougher, making it more healthy or easier to farm?

Aaron Jozsef

What country is the largest consumer of grown seaweed? Follow up, what's the best recipe for cooking it?

Kaitlin Westphal

I was told eating seaweed was good for you, but then I saw an article about seaweed having high amount of microplastics. Is that true or flim-flam?

Voxothoth

How long has seaweed been around for? What were it's ancestors?

JENN 'Benthopelagic squirrel' ALVAREZ

Why is dried seaweed so yummy? Does all seaweed taste the same? I just realized I don't know dick about seaweed. I have all of the questions.

Crystal Wilson

You ever take washed up seaweed, shake out the critters? I use to check them out and set them free as a kid. Grew up and got a marine bio degree 😂

Michelle Lee

Is the seaweed I eat (for example in in Korean seaweed soup, dried laver sheets, or seaweed salad) the same seaweed species? Are all seaweed edible?

Lunarcrumpet

What kind of bugs/micro organisms live in/on seaweed?

Flozzatron

Does the structure of seaweed help keep the coast from eroding, I know it doesn't have roots but can it's growth help keep erosion from happening and loss of coast? Also are there any really strong varieties that would be like takeover species? Would some become like a monoculture by pushing out other rarer species?

Penny Loader

What's the best seaweed pun you've ever heard?

lolomclolo

I grew up in San Diego and fondly remember finding enormous kelp bulbs on the shore. They were HUGE! How big does it get and what’s the largest known specimen?

Meaghan Ratcliffe

can you eat the creepy seaweed that tickles your legs at the beach? or is there a separate edible seaweed species/strain?

Jenna Congdon

How does seaweed survive in saltwater, when most plants perish at the slightest hint of salt? It always feels rubbery or slippery to me, whereas freshwater plants feel softer and slimy. Does the seaweed have some sort of barrier or structure protecting it from the salt? Or is it a cellular process, with the salt somehow being pumped out?

also_ally

How do you manage invasive seaweed? And how is it different from managing terrestrial invasive plants? (Pesticide seems like a bad idea in the ocean) In Hawaii we have a lot of gorilla ogo and as a kid, I went on field trips to do cleanups where we picked it by hand.

Ara Victor

First time asking a question! Did seaweed originate on land and then migrate into the ocean? Does it photosynthesize? I imagine it can only grow so deep before losing sun access

Mariah Walzer

I think I once heard that all species of SoCal seaweed is safely edible. Is this true? Tips for safely foraging seaweed?

Mariah Walzer

Is there any way we can help seaweed? (Does it need help?) Is it any use throwing beached seaweed back into the ocean?

Gina H

Seaweed is my favorite popcorn topper!! My dog likes it! But then I saw a prop 65 warning on the back of the label- what is that all about? Where can I find safe seaweed to eat? All I know is I can devour sheet after sheet...after sheet.....

Jernelle

Yes! Ok so the only reason I know this is for a VERY weird reason. Buckle up! I am an educator for a medical skincare brand and we use Hydrolyzed Algin (from marine algae) to treat Rosacea because your skins neurons actually can build up plaques from amyloid proteins, the same way your BRAIN does. This causes unhealthy cell communication and decreased nutrient exchange. There is also growing research in a correlation of Rosacea and neurodegenerative diseases!!!

Emily Gilbert

I've seen seaweed powder in food and cosmetics usually with a list of health benefits. Will the the seaweed health shake really give me better skin, more energy, vitamins, and the power of flight? or is that just flim flam to get me to buy it?

SarahN

I immediately wanted to know the expert’s thoughts on sargassum! (But, it’s actually an algae, I realized after a quick search). Still, my family live on the Gulf of Mexico and I visit the coastal Mexico often and the sargassum can be a real problem! I believe it’s over abundance is due to agriculture runoff. I’m mostly interested in creative innovations to use it! I’m aware of a Mexican man turning it into building bricks. More about this kind of use and innovation! (Not sure there was one single question in that ⬆️)

Julie W

What’s up with the seaweed that takes away the methane in cow farts and burps, and is it going to save us all?

Leah Anderson

What is the deal with Eurasian Watermilfoil and why is it in the Great Lakes?

Erin White

What makes something a seaweed?

Raja

How many different species of seaweed are there and do you have a favourite? (Raja rhymes with Papaya)

Raja

How tolerant is seaweed to polluted waters? Or does it drastically depend on the species? (Raja rhymes with Papaya)

Anastasia Press

How much seaweed is a helpful amount of seaweed? What happens if there's too much or too little of it?

Raja

Are you picky about people referring to plants growing in freshwater as "seaweed"? Because I am... a lil' bit. Should I just get over it? (Raja rhymes with Papaya)

Haley K.

When i’m swimming in the ocean and weird slimy seaweed scares me by unexpectedly rubbing against my leg, how do I know it’s a safe kind? Or, I guess first, are there harmful or dangerous seaweeds?

Anastasia Press

Can you make stuff with seaweed? Like could you weave it to make baskets, or spin it into some kind of yarn? What kind of art have people made with seaweed?

Haley K.

Excuse me, it doesn’t have roots?? Even the big kelp forests?! That’s nuts!

Raja

Is there a way to purchase seaweed snacks with way less packaging? I love them but can't bring myself to buy them because of all dat plastic! I know, I know, make it myself...

Raja

Who are seaweed's most significant consumers? Besides potentially humans. (Raja rhymes with Papaya)

Staci Pinkowitz

FINALLYYYYYY Ok I heard recently that some species of kelp are more closely related to malaria than to land plants. A) did I hear this on a different ologies episode bc it may be the case and B) can we talk more about this because it’s been curdling my brain

londennoelle

Are there any types of seaweed that can filter pollutants out of the water at a significant rate? If so, are any efforts being used to combat the acidification of the ocean. If they are, what is to stop them from overpopulating and creating an imbalance in the ecosystems they are found in?

Staci Pinkowitz

Ok what exactly is seaweed. Is it closer to a loose cultural category than an actual thing? Is seaweed a very specific kind of sea weed and the rest of what’s going on down there are being lumped in

Elinor Wahl

When oil companies were trying to get into the Amazon rainforest in Ecuador, one of them submitted an environmental impact report claiming that only 5 plants of the countless species in the affected area were of special consideration. What seaweeds do you think deserve more attention for the special role they play in the environment?

Staci Pinkowitz

Histories of seaweed and people around the world? Cultural significance in diff places?

Katy

Would love to learn about legit medicinal uses for seaweed, and history of those kinds of uses. (We feed my dog a seaweed powder supplement called PlaqueOff thats VOHC-accepted so it has research backing its effectiveness for preventing plaque and tartar... How did people figure THAT out?)

Melanie Ang

I’ve heard of one climate solution that is using kelp farms to sequester carbon dioxide from the atmosphere and then letting it sink to the deep ocean. Is this a viable solution and what are the consequences of having so much seaweed on the seabed if this was to be implemented on a large scale level?

Staci Pinkowitz

I’m picturing a dark seaweed forest in the ocean. Is there an analog to a forest canopy underwater? What species do well growing together or have different roles in the ecosystem?

Staci Pinkowitz

When I soak kombu to make dashi stock it makes the texture of the broth sooo thick and nice. What exactly is the slimy component of seaweed and what is its biological purpose?

Flozzatron

Maybe double check that but I thought they just all kind of cling on to stuff.. maybe we should ask that question 🤣

Caroline

Two question groups! 1. Is kelp a kind of seaweed or its own thing? Are there other non-seaweeds that look kinda grassy? Are seaweeds related to land grasses? 2. Obviously there are many kinds of seaweeds, so when I hear "seaweed is good for you".... what kind?? I hope it is the kind in the seaweed salad you get at sushi places and that the vinegar etc doesn't ruin the good nutrients....

Robin Stumbo

in areas where seaweed has been overharvested (be it by people or urchins) can it be restored and how? are there any seaweeds that may be more resilient to warming waters as a result of climate change? which one smells the weirdest?

Leanna Shuster

Is there a difference between seaweed and kelp? Two names for the same thing or is kelp a variety of seaweed?

Liv Cazzola

Why oh why do I hate the feeling of seaweed brushing against my feet in the water even though I know it won’t hurt me? Are there any fun folk tales about seaweed?

Kelly Walker

I AM SO HAPPY TO BE HERE ALSO I WANT TO KNOW WHAT ARE NOT TRUE RUMORS ABOUT SEAWEED??? MY NAME IS RONAN AND I AM SO HAPPY RIGHT NOW!!

Leanna Shuster

How many species of seaweed are routinely used as food by humans? Are there any types of seaweed that are specifically dangerous for consumption by humans?

Obilot

What makes seaweed SO DELICIOUS, especially in soup???

Ashley Sayre de Rivas

When did people decide to first start eating sea moss aka Chondrus chrispus? It's touted by some to "have 92 vitamins and minerals", help clear lung congestion, and help with immunity among many things, but aren't most edible seaweeds generally great for iodine and trace minerals?

Gwen Kelly

Is “seaweed” like a real biological family of related species? or it it kind of a folk category of just anything humans lump together as plant-type things that live in the ocean? Also what are they evolutionarily related to? Are there seaweed fossils? How old is seaweed? Does it go back to like a primordial soup (i think my imagination of the early ocean looks a lot like a miso soup).

Gwen Kelly

What is the role of seaweed in global climate? Is it important for carbon sequestration? Are there any endangered species of seaweed? Or is seaweed just like thriving? Warmer oceans, nutrients in runoff from agriculture? I guess I’m asking is are we humans helping the seaweed or hurting it?

Kellie Due

What are the best seaweeds to eat?

tamalamb

What's the deal with microplastics and seaweed? Is there a deal?

Tessa Lew

How big of a problem are sea urchins that are eating the kelp forests off the coast of Northern California? Why is it a problem right now? What have been some of the effects of the loss of the kelp forests?

Lorri Fishman

Kelp is one of the only veggie sources of vitamin B12 — tell me more, please.

Thorpasaurus Jess

I AM POSITIVELY BURSTING EITH EXCITEMENT! First question: How has there not been a seaweed episode before? Is there one that I missed?

Leo Chiang

does seaweed consumption help with vegans and their complete nutritional intake?

AJ

Could you please talk about the relationship between otters, sea urchins and kelp forests? Specifically how the over hunting of otters proved them to be a keystone species. It was one of those things I learned in marine biology that really stuck with me and I think others would enjoy hearing it

Emily Krieger

should I put gathered, chopped seaweed in my garden soil? would I want to avoid using seaweed from polluted bodies like Elliott Bay in Seattle? thank u!

TheAmazingMissJ

Why is seaweed often so slimy?? "Why does it feel like it's something grabbing you from the depths of the water?" (Asks my fiancee Chase, who showed me Ologies and is sitting next to me)

ariel.vanzandt

Seaweed vs Kelp - what's the difference?

ariel.vanzandt

How are seaweeds different from the plants that grow in creeks/rivers and lakes?

ariel.vanzandt

Do seaweed species co-mingle with each other or do they stay pretty separate? Is it based on water depth?

Kaitlin J

Came here to ask this! It’s a huge deal for the area and I know a lot of it gets burned but it I always wondered if there could be more uses for it!

Sabrina Shaw

Is there is a way to measure the CO2 in the bulb of the bull kelp? What other gases are in the pneumatocyst?

Kaitlin J

I know nothing about seaweed farming, but I want to know everything now that I know it exists 👀

Kaitlin J

Does seaweed have any unexpected relatives?

Saira (‘Sarah’) Manns

Is it actually a weed? What even is the definition of a weed? Is this just blatant sea slander?

Bonnie Steele

Is yarn made from seaweed and eucalyptus (like “Seacell”) really as eco-friendly as marketing claims make out? And does it really bestow magical anti microbial and mineral rich powers? I recently splurged on a Seacell and organic cotton blend yarn to knit a baby blanket and it did turn out super cute and soft!

Addie Cappello she her

Oooh so fun!! This brings me such good memories of my childhood. Can you eat all types of seaweed? Are there any toxic types? Why are there times where there’s a TON of seaweed washed up on the beach and in the ocean and other times not so much? Is all seaweed attached somewhere or is there free flowing seaweed too? How does seaweed undergo photosynthesis under water - or does it!? Is there a difference between kelp and seaweed? I always feel like seaweed is such a generic (and negative?) name for sea vegetation. When did humans start eating seaweed? What foods contain seaweed that we don’t know or think about? I always think about this as a vegan but- basically seaweed is marinated in all sorts of dead/live marine creature-ness…. How much of seaweed contains particles of non-vegetative stuff that ends up getting eaten by humans? Are there any types of seaweed that act as filters for the ocean? Thank you!

Tegumante

Has there been any progress in the last few years on using seaweed as a means of CO2 drawdown? I remember it was held up as a promising avenue to explore, but I haven't heard anything about it in a while...

Emma Fiori

What's your all time favorite algae species (or genus, or family)? Could be based on looks, cool-factor, ecological role, or taste.

Emma Fiori

What is the status of macroalgae ID by DNA sequencing? I understanding there are a few regions being used for DNA barcoding, but how universal are they? Do you know of any public sequence databases like for 16S and 18S for bacteria and fungi? Do you know of any commercial labs that offer DNA ID of various marine algae? Oh, and are there any international herbariums cataloging algae species from around the world? Thanks so much for helping with my research!

Kathleen Regovich

What’s the difference between seaweed and algae?

Emma Fiori

How common is adulteration in commercially important algae, particularly in the nutritional supplement industry? Are there any frequently adulterated species you know of?

Alisha Harris

Are there any endangered species of seaweed that we need to look out for and protect? Or are they all pretty common?

Alex

Where do seaweeds fit in evolutionary history? I know waaay back when all plants were aquatic, and they only later migrated onto land. Since some modern seaweeds live at this land–sea border, are they at all related to the first plants to colonize land?

Saira (‘Sarah’) Manns

Yes! Is it safe for me to pick up any rando bit of seaweed on my local beach and chow down?

Keiki Kohne

How is seaweed used in make up or in medicine?

Keiki Kohne

Do you think seaweed could become as common in people’s lives as, say, soy or corn?

Keiki Kohne

Why do we see so much seaweed washed up on beaches sometimes, like I saw when I was in Cancun a few years ago. Is that normal, or a sign that something’s off in the ocean?

Gertlebob

Who figured out it was so tasty? Like, who's idea was this? I thank them.

Nina Toy

First time question asker: What steps do you think could/should be taken to normalize seaweed as an alternative resource?

Evelyn Uyemura

What does nori look like when it's alive?

Anna Vilnīte

I don't have a question but I have a dad joke: why is the beach wet? Because the sea weed.

Annie

I’m assuming you are interviewing Bren Smith! First time question asker and seaweed enthusiast asking: how viable is seaweed fertilizer as an aquaculture product at a large scale? Are there any lessons you are learning in seaweed aquaculture that can help inform kelp restoration techniques? What are your thoughts on efforts to sink seaweed to the sea floor to sequester carbon? Can it be scaled to make any meaningful difference?

Annie

This!!!

Annie

Many kelp species have holdfasts, which aren’t a true root system. there is no exchange of nutrients through a holdfast , it only anchors the kelp to the seafloor or rocks. Yes kelp forests reduce erosion by attenuating wave energy

Felipe Jimenez

Are there any biofunctional properties for sea weeds that are worth further exploration? Health related properties that you want to highlight?

Mollogies

First-time question asker! Can (any) seaweed grow in any water/temperature? Under which circumstances does it become the tastiest? There is seaweed farming somewhere on the Swedish coast, but I’m unsure whether it’s on the eastern (along the brackish Baltic Sea) or western (along Kattegatt/Skagerack, where the brackish bitch meets the salty slut 🌊✨💙).

Annie

Please do a seagrass episode in the future!!!

The Farming Linguist

Why do foraging resources always say to never forage washed up / dried out seaweed? And is it true that there are no poisonous species of seaweed, only more/less desirable culinarily? (Also, what are the best varieties/preparations for eating seaweed in a vegetable quantity, as opposed to a seasoning quantity?)

Victoria scholes

Is there a particularly beautiful type of seaweed

Jess Hamilton

Is it true that sexy seaweed pheromones are what makes the sea smell like the sea?

Jess Hamilton

Are there otters around his seaweed farms? Is he near otter rewilding programs? Otters!!

Jess Hamilton

Would love to hear stories about collaborations between First Nations peoples in seaweed aquaculture or restoration projects where he is

MyLien LyTrang

What’s the difference between the seaweed we eat and the seaweed in the ocean? Are there seaweed farms just for food?

Spicy Native

What role does seaweed play in climate change and hopefully the reversal of the damages being done on the planet? Follow up; what can the average person do to help seaweed continue to thrive and potentially help climate change reversal? (If at all possible)

Ruby Gordon

Is it sustainable to eat seaweed?

Britt Kline

SUCH a fun question!!! Yes! 🤩

Elyce

Why are some types slimey and others not?

Fuzzgoddess

How long until we start seeing it in the regular grocery store? What would be the storage conditions for fresh seaweed? I've only seen it dried in asian groceries so far.

Fuzzgoddess

Follow up: how do you cook it as a veggie and how much would count as a serving?

Mamabee & DadAussie

Seaweed in my compost. Yes, or no? Is removing seaweed from the beach for this purpose sustainable/ethical, or can it be done sustainably/ethically?

Theladyisageek

Is it true that some people have the ability to digest seaweed to extract the nutrients and others don't? Does making seaweed a regular staple in your diet help you develop the guts to digest it?

Staci Pinkowitz

You phrased your question vvv well I am also wondering what exactly it is categorically

SoManyQuestions

Where are most seaweed farms located and what’s a day in the life of a seaweed farmer? Do I want to be one when I grow up?

Andy Pepper

I know they’re algae, but how does seaweed biodiversity compare to land plants?

Andy Pepper

Does seaweed work well as a carbon sink? And how are they doing, in general, in warming oceans?

Shannon O'Grady

My sister and I are irrationally grossed out by swimming and touching seaweed. Help me get over this. Why is it so disgusting?

Zinc

is it true that all seaweed is safe for consumption?

Chloe

Hello! I heard about seaweed based shopping bags and how it can replace other plastic dominated items. Is seaweed a good alternative to plastic? Is growing seaweed a sustainable practice?

Priyukli

Curious to know about how seaweed species will fare as the climate crisis worsens - and if there's a role for seaweed/ aquaculture in climate resilience or mitigation?

Rachel Roman

Why is it called seaweed? Weed makes it seem like a nuisance or invasive. And how is that different from seagrass. And why does seagrass get the nice sounding name? Who does their pr?

Faith Stemmler

I love the long, slimy kelp forests! Such an incredible keystone species, thank you for discussing them! I want to know how good they are at mitigating wave action on the coasts and and whether the sustainable practice of seaweed farming can be upscaled enough to make a significant impact in carbon storage and habitat repair.

Deli Dames

Is the dry roasted Seaweed in packs the same seaweed as Seaweed salad? If I find Seaweed at the beach could I clean it and eat it? What is the longest recorded Seaweed? What is the deepest depth of the ocean that Seaweed can grow?

Scalebar

As a keen eater of the stuff. What is it that makes dulse so deliciously bacony?

Got_any_grapes

Favourite seaweed recipe? I have seaweed or seagrass growing along the beach of my cottage along the Saint John River (freshwater) would there be any reason it wasn’t I edible and if so I’d love to know how I could cook it up in the tastiest way.

Sage-Against-the-Machine

FTQA: At what point does marine pollution lead to seaweed that has as much toxic residues or accumulations as commercially produced land foods?

Sue MyShak

There’s so many companies utilizing seaweed as a substitute for plastic (I.e. Sway out of CA/USA, Notpla in the UK) but when will see that translate overall so it ends up in our grocery stores and can finally start tackling the plastic pollution problem. Also if that happens what would be the main repercussions to farming seaweed on a mass scale.

Tilly's mom

Why is it so terrifying when it touches your leg while swimming?!? 😂

Corrie Francis Parks

What's the deal with the seaweed sweater ads the algorithm keeps sending me? Is it scratchy? Is it soft? Is it actually a sustainable fiber for clothing of the future?

Suzanna Green

My question is also why are there certain times when the seaweed is all over the shallow water and a ton of it washes up on the beach and other times it is nowhere to be found? And is it best to remove the seaweed that is washed up or leave it there? The beach closest to me pushes it up to the dunes but I've heard that's not the most sustainable practice.

Chelsea Wilck

Growing up in LA I was absolutely TERRIFIED of the seaweed in the Pacific Ocean but also kinda loved it THEN I was absolutely devastated to find that the Atlantic doesn't have that same slimy but cute type of seaweed but rather little stringy wisps of seaweed (at least in Florida)...why does the fun seaweed not exist in the Atlantic/is there a cooler seaweed in the Atlantic that I just fully have missed??? Are those wisps even considered seaweed or was I lying to myself?

Raevenote

Ok, it seems like seaweed farming could be really sustainable and productive - how do we keep from turning the ocean into a mono cropping nightmare like land farming? Also: i’d like to know more about medical applications of seaweeds (beyond green smoothies). Thanks! Alex and Cynthia

OnyxMonolyth

Is the Ologist actually just some seaweed in a trench coat? Or perhaps being funded by Big Seaweed to get more seaweed into our bodies for some sort of nefarious plan? Actual Question: how does seaweed’s historical uses by non-European groups compare and contrast to our own usage of seaweed? Have people farmed and eaten it in the past or is that only a new development? How do we actually farm seaweed? How do the hydrodynamics of the water apply to it? If I made a combine into a submarine, could I harvest a large amount of seaweed or would it just not work because combines are made for land?

Melissa Mark

Are they still discovering new species of seaweed? Is it hard to identify seaweed to species? Can you eat all kinds of seaweed? How many kinds of seaweed can you eat? How long have people been eating seaweed for do we have archaeological evidence of seaweed farming in the Neolithic? Is there a seaweed recipe cookbook? Is seaweed worse for you now due to microplastics or heavy metals in the ocean? I love seaweed so much I have so many questions I should probably stop now

Danae Sprouse

So curious about seaweed clothes. Are they made out of 100% seaweed?

Nayomi Santos

In what unexpected ways is seaweed beneficial for humans and animals alike?

Brittney Corrigan

I know there is a very important relationship between sea otters and the health of kelp forests. Are there any other animals that have this kind of symbiotic relationship with seaweed?

Why does seaweed help poison ivy rashes?

Sophie

From a surfer, how does seaweed affect surf breaks? Breaks with kelp beds offshore and/or grass underneath are usually much better than breaks without for me, but why?

Between Dumplings

So many uses for it and so many types. Japanese revere special types of kombu which is related to kombucha and which also carries umami something lots of vegans miss. I put a piece in my rice when I cook it, then chop up the cooked kombu in a quick cucumber salad. We also eat other types like wakame, hijiki. Some are farmed in Maine, I think? I hope seaweed farming is not as onerous environmentally as fish farming.

Olivier Calas

Would love to know more about current studies on seaweed used as biofuel…

Cate Muenker

I've always wondered how much seaweed there is in the ocean- like how much would sea level change if there was no seaweed? Does fertilizer runoff cause seaweed to overgrow or die off?

Shale

Was wondering about this as I keep seeing posts about seaweed being turned into yarn! I crochet and love learning about sustainable fibers but I’m curious about that one.

Shale

Yes this!!

Kristyn Remme

First time question asker! I’d love to know more about the sargassum seaweed problem affecting beaches in Mexico and other Caribbean nations, and what the locals are doing about it. I heard there is one man who figured out a way to build houses with it!?

Kristyn Remme

Ouu, maybe on that note you could tell us more about the Sargasso Sea… and the eel migration!!!

Lizzy Carr

Can you pull seaweed out of the ocean and just eat it? Or does it need to be processed in some way before it's safe to eat? I used to eat seaweed out of the ocean when I was a kid and now I'm wondering if I got lucky avoiding some kind of ocean bacteria lol

Bonnie M Rutherford

When I lived on Kodiak Island in the 70s we didn't have much access to fresh vegetables so we ate a lot of bull kelp. We ate it fresh, dried it and even pickled it. Kelp pickles were my favorite. I now see dried seaweed packages in the grocery store but I was wondering if kelp is now used commercially to make pickles because they're my favorite.

Ursula Goodwin

I’ve heard about many great innovations from seaweed farming such as the possibility for seaweed to reduce methane production in cows, sustainable packaging and plastic replacement etc. what are the barriers that are preventing these innovations from going mainstream? (1st time question asker xx)

Danielle Zonis

What are some of the health benefits humans get from eating seaweed and does it change if the seaweed is roasted or dehydrated? I've found that in the last couple of years I just love having those roasted seaweed snacks with me, I even tend to eat them with my meals sometimes + I love love love sushi.

Bird Nerd

First time question asker! Yay! How has the overpopulation of sargsssum in some areas affected eel migration?

Kieran H

What do you have to do to seaweed before you can eat it safely? I’m assuming that you can’t just pick it up off the beach and eat it—or can you?!

Kieran H

What is the difference between seaweed and kelp?

RoadLesTravelled

What other sort of things, rather than food or cosmetics, is seaweed / kelp used in. What about freshwater aquatic plants which have seaweed-like characteristics?

Cat Kessler

What would it look like (from a nutrition, production, and culinary perspective) to make seaweed a bigger part of our diets? And I hope you’ll talk about the opportunities of vertical ocean farming!

Baylee Bug

Have you seen the Barnacle Co seaweed pickles? They sell them in SE Alaska, based out of Juneau!

Bonnie M Rutherford

That's great but I no longer live in Alaska. I live in Washington State.

Jeanette-o-saur

Seconding this entire set of questions 😁

Ry_ofthetiger

Sargassum. Tell me all about it. Why is it everywhere, in huge piles? Why is it so stinky? What creatures live in it, eat it, love it? What can we do about it, and *should* we do anything about it? Oh, and why is its name sarcastic orgasm, thanks.

Keely Chavez

This... When is it so polluted we can ONLY depend on "farmed" seaweed

Keely Chavez

Right!? Are there currently species at risk for extension?

Ry_ofthetiger

Spirulina. Is it seaweed? Is it something different? Is it really that good for us? How hard is it to grow in your backyard?

Ry_ofthetiger

Is it true that algae was responsible for one of the major climate events in geological history? What can it teach us about how the Earth’s climate changes?

Keely Chavez

A weed is just any plant you don't want, right? so I say NO! Slander!!

Keely Chavez

I've always wondered if it were dyed or if it has anything to do with the pickling process.

Keely Chavez

Dying to hear this... could be quite prescriptive for some :D

Keely Chavez

Lotta questions about seaweed/sargassum/kelp, algae etc.... Do they naturally compete for habitat?

Keely Chavez

Just had it last night, and still, yes please! :)

Eli “the Fish Guy”

Why is seaweed so expensive? I love the little roasted seaweed snack packages, but they're like $2.50 a piece! Also, how is the seaweed harvested to make roasted seaweed snacks?

Nickle Le$$

There is evidence that suggests the “peopling” of North America originally happened via coastal travel. Assuming those people ate seaweed, what kinds of seaweeds did they eat and how do you think they prepared it? Raw? Freeze dried?

Ry_ofthetiger

I think I wrote it with Pops’ voice in my head, and I’m okay with that.

Jules

I’m so sorry to piggyback on this post, but how do we suggest ologies to do an episode on? I’m newly subscribed at the Buddy Tier, but I can’t find a button or a thread for it.

Mouse Paxton

Has seaweed been a historical source of fertilizer? Liquid seaweed is one of the fertilizers we use at work and I was curious about its history! What kind of seaweed did they emulate in Minecraft? Was it a faithful adaptation? Why does eating seaweed make me gag? I want to like it but my body won't let me. What's your favourite species of seaweed?

fullmetalknee

Are the modern snacks with the farmed or wild harvested? Are they sustainable and ethical or are they being taken from others like the issues surrounding bottled water?

GhoulNextDoor

Have humans subsisted off of seaweed and the environment that surrounds the seaweed in the past? If so in what ways? What archaeological and/or cultural evidence is there for the ways in which it has been used?

GhoulNextDoor

Yes! I’m really curious about if and how seaweed contributed to the peopling of North America! I second this

GhoulNextDoor

What other types of creatures exist along side of seaweed? Does it provide important habitat?

GhoulNextDoor

Is there anything we need to be cautious about when consuming seaweed? I’ve heard of potential contamination because of pollution in our waters such as mercury and micro-plastics. Or is it ever harvested in an unsuitable way that we need to be aware of as consumers?

KristieAdventure

FTQA - maybe this isn’t a seaweed question, (maybe it’s an electric power generation episode suggestion) if we have too much sargassum washing up, can we toss it in a digester like they use for food waste and run a bio-gas generator set from it? A win-win for the environment?

Kristin

Seaweed has a rich history in Irish agriculture since it was free :)

Willow Hall

What actually is seaweed?? Is it a bunch of different plants with a similar structure like trees? I've even heard it compared algae. Please explain this mysterious creature to me! Also why is seaweed of such high interest to groups looking for sustainable alternatives to plastic? Thank you, for covering this Pod Dad! Seaweed has long left a salad sized confusion mass in my brain 🤣 Stoked for this episode!

Jessica Lightfoot

How can we cultivate seaweed inland? Like for the everyday plant/planet lover

Jacob Morvay

This. Why does it enjoy ruining the beach?

Bonnie M Rutherford

Several of my Native American friends have told me their grandparents said that kelp and other seaweeds were used for medicine but they didn't know the details. I can imagine that the iodine could be used to treat some disorders but I was wondering what other medical uses there are for seaweed.

Katie Biardi

Are there any seaweeds that you can't eat because they're toxic? Like how some plants produce compounds that are toxic to humans or other animals.

Kim G

Is there a different name for seaweed that grows in fresh water, or is it all called seaweed despite the name?

Mariko

My grandparents used to take me to gather seaweed along the California coast with our Japanese American community back in the 1980s. We'd all get on a chartered bus with our picnic lunches, hip waders, and buckets. I don't remember what kind we gathered -- wakame, perhaps? -- but it is one of my most vivid cultural memories. Is this still a safe thing to do (water quality wise) and is it legal to forage in this way? I'd love to keep this tradition alive with my kiddo.

TB33

Is seaweed the next hot commodity? I recently saw an ad for sweaters made out of seaweed and it reminded me of the hemp craze. So is seaweed the hemp of the sea?

Annabelle

Could you tell us about endophytes and epiphytes living with seaweeds? Can they help seaweeds stay healthy?

Kudzzzu

Looking forward to this topic! Does seaweed farming use pesticides or other methods of controlling the farm environment and stopping animals from eating the crop? Are new types evolving or being cultivated?

Cloudsnbugsnshrooms

PLASTIC! Are we gonna use our slimy friends to replace plastic or what?!

Earl of Greymalkin

1) Seaweed as a name sounds a little insulting. Is seaweed really like a weed in the sea or is there a better analogy? 2) Are all seaweeds part of the same branch on the phylogenetic tree or has there been a bunch of convergent evolution? 3) How many are edible versus poisonous versus just not a good idea to try to eat for whatever reason? 4) How scalable is seaweed farming and where does it happen? Do you have to be in the actual ocean or can you make a controlled environment on land? Can people grow seaweed to eat in the backyard? 5) What kinds of alternative materials are people trying to make with seaweed? 6) How is seaweed processed that all the little creatures that might live in it are removed? Can it get contaminated by algae or other organisms? 7) What is the harvesting process like? Are there scuba divers with scythes or an aquatic combine harvester? 8) What is your favorite way to eat seaweed?

Eileen Wang

Can you spin seaweed into textiles? if so, how would this compare to land-grown fibers like cotton and hemp in terms of sustainability. When can I have a seaweed shirt?

Lindsey Wallace

what is WITH the seaweed overgrowth in places like mexico? I had no idea this was such a massive issue for tourism.

Barbara Blackie

I always hear that the bulb of a bull kelp has enough carbon monoxide to kill a chicken- is this true? Also, is there a function or reason that bull kelp would produce CO and not just CO2 or O2?

Rob H.

I wanna know about all the edible kinds of seaweed. There have to be other kinds we're not eating in the US, right? Are there a bunch of different flavors and textures?

ReigningEmily

As someone who lives a good distance from the sea, how can I get involved in the wonder that is seaweed?

BENJAMIN

Is seaweed a superfood? What kinda of nutritional benefits does seaweed have?

Steven Lee

It’s not like an umbrella term for any plant material adrift in the ocean is it? Or is seaweed actually a specific plant species?

Blobfish guy

What is the effect on other plant and animal life if there was an excessive amount of seaweed in a certain area.

DudeWhereAreMyWheels

It seems like seaweed has the capability of saving the world between it’s ability to pull carbon dioxide out of the atmosphere in vast quantities, there are edible varieties that can help feed the planet, it can be harvested and use as fertilizer, it can be used to filter out pollutants from getting into the ocean, it has many different industrial applications, and the list goes on. Is there one particular area that would be best for the country to focus on that will have the greatest positive impact on the environment?

Tara Ward

What creatures eat seaweed?

burke Stansbury

This is from my son Lucas, age 15 (and a big fan of the podcast!): - Does seaweed have any defense against animals that eat it? - Is seaweed popular as human food in some parts of the world? Is it at all healthy and/or delicious?

Kai Muir

Are there many Indigenous managed commercial seaweed aquaculture operations in North America? How can seaweed aquaculture be developed in a way that respects Indigenous access to the shoreline and doesn’t appropriate/non-consensually commodify traditional seaweed harvest?

CurtisDawg

Once the word really spreads on the many healthy benefits of seaweed, could we run into issues of overharvesting?

Keegan Newman

Is seaweed found in fresh water, like the Great Lakes? Is it different than the seaweed in salt water? Is all seaweed considered algae?

Kittens8myhomework

FTQA: I've known for a while that many commercial ice creams contain seaweed, but why? And who decided that seaweed was the ingredient to use?

EmiTheStrangest

My seven year old step son who also loves your show would like to know how many different kinds of seaweed there are AND is seagrass a type of seaweed?? THANKS WE LOVE YOU

Marisa L

Hi! FTQA :) What are the impacts on wildlife for in ocean seaweed farming/culturing? I know some juvenile fish species and other invertebrates use seaweed/algae as a hiding place or nursery. Is there a lot of bycatch when harvesting seaweed? Also ps I love your podcast so much!! :)

theshampooplanet

Hello! 2ndTQA If this is with Bren Smith I'm extra excited. If it's not, I'm still stoked. Would love to know if there are any fresh water opportunities with algae/seaweed. To my understanding regenerative ocean farming is limited to well, the ocean... Hopefully there are some sort of fresh water applications!

Meg Chadsey

First time question asker Meg the Seaweed Lady! There are so many good reasons to cultivate seaweed commercially and for restoration besides (largely unsubstantiated) claims of carbon sequestration. Given that under most conditions (https://www.nature.com/articles/s41558-025-02278-1) only a SMALL fraction of farmed seaweed gets buried on seafloor for any meaningful length of time (so probably not the climate change-fighting, carbon credit bonanza it's often made out to be), are there OTHER opportunities for seaweed farmers to be compensated for the multiple ecological co-benefits they DO deliver? Talking about habitat, food for sea critters, shoreline protection, water quality improvements...

Kittens8myhomework

I have SIBO (small intestinal bacteria overgrowth), essentially my stomach reacts to things negatively than most like leafy greens and fruits. Seaweed is also one of them. It breaks down to a gelatinous state that irritates the GI of the ever so sensitive like me.

Amanda Sanders

Amanda first time question asker. Are they researching how to use the seaweed that drifts up on the Shores of the Caribbean, Sargassum? Always been curious about that.

Ashley Brown

Does seaweed grow in forests like kelp does? And if so, I assume it is also sequestering CO2 for us? Is the seaweed doing okay??

Kaeli Duffy

Is there a reason that I want to touch all the seaweed at the beach and rate which is the slimiest?

Pamela Vorce

FTQA, I grew up on the east coast and never saw seaweed on the beaches we visited. I assume the beaches of California have so much more due to warmer temperatures. I love Cali beaches, but ugh it stinks, and attracts lots of bugs. Do some beaches remove it? How much seaweed washes up on shore each day. Do some beaches remove it? If so, do they have an alternative use for it? Thank you!

Amanda Lask

Did corals or seaweed come first?

Amanda Lask

How many species of seaweed are there?

Beeve of Dudley

I ate a small bite of random seaweed from a tidepool on the Oregon coast after hearing about seaweed foraging. I threw up a few minutes later. Are there types of seaweed that are poisonous to humans?

FaeryJessa

Can seaweed come in more colors than humans can see?

KC

epiphytes! please tell me about their epiphytic communities! what creatures would not exist without seaweed and the community they create? (FTQA)

KC

are all seaweeds protists? are all protists seaweeds? what separates seaweeds from plants? (FTQA)

samwambam

What would the world look lile without seaweed?

Mariah Wenzel

What’s the process to prepare seaweed for eating, like dried nori but also slimy seaweed salads?

Jessie Crawford

How are kelp forests doing along the west coast? Are there any efforts being made to protect them or try to grow more so we can have a better chance of reintroducing sea otters, who rely on that kelp?
