Image a spot on the centre of an international seaweed revolution. I’ll wager the small English seashore the city of Paignton in south Devon isn’t what involves thoughts. A decade in the past, I moved from the brink of Dartmoor to the coast. It was once a couple of easy trade in work-life steadiness, however what adopted was once extra unexpected.
The children have been 4 and 7. I’d at all times attempted to encourage them with my medical analysis. Shifting to Paignton and strolling alongside Broadsands seashore someday, I began noticing piles of seaweed.
I’d spent my complete skilled occupation researching microalgae (microscopic marine crops) however knew next-to-nothing about their larger macroalgal cousins, the seaweeds. This felt like a chance to have some a laugh and for all folks to be told in combination.
So I purchased us a seaweed guidebook, some stickers and set the Allen circle of relatives the duty of discovering ten other seaweeds on our native seashore. We’d mark a web page with a sticky label after we discovered it – without equal medical praise chart. A couple of weeks later, we’d discovered 30 and exhausted our sticky label sheet.
I used to be amazed on the variety that I had by no means up to now spotted. The colors, the textures, the buildings – it was once like I’d by no means in point of fact observed seaweed correctly sooner than. The pro scientist in me kicked in.
My children and I began taking samples house. I constructed the children a lab in a lean-to at the again of the home. We dried them out and put them in little jam jars, corresponding to a seaweed spice rack. It were given me pondering of helpful or sustainable issues I may just do with them.

Sooner or later, I posted an image of those jars on Twitter, with the hashtag #SeaweedApothecary. It began one thing I may just by no means have predicted.
Seaweed has an astonishing collection of makes use of. It may be used to provide biofuels and fertilisers, meals similar to laverbread, nori sheets for sushi and crisps, cosmetics and toothpaste, prescribed drugs and meals dietary supplements like omega-3. I’d additionally been incorporating seaweed in my day by day analysis on the College of Exeter, seeking to convert it right into a biofuel.
Then, my colleagues within the broader educational and business science neighborhood began requesting samples. Like me, they’d been ignoring seaweed too – till they noticed my social media posts and realised the possible.
The children (now each youngsters) are said on no less than a dozen medical analysis articles and feature persisted to assist me unencumber the opportunity of seaweed. We’ve achieved degradation experiments within the raised beds in our lawn, examined other seaweeds as feeds for a pal’s chickens, trialled them as fertilisers for our tomatoes – even blended dried seaweed powder in with cement, to look if it may be used as a structural subject matter filler. All a laugh, easy science that any one can do at house.
Native science, world tales.
This text is a part of a chain, Secrets and techniques of the Sea, exploring how marine scientists are growing local weather answers.
In collaboration with the BBC, Anna Turns travels across the West Nation sea coast to fulfill ocean mavens making thrilling discoveries underneath the waves.
Swamped via sargassum
Then got here a choice from a Mexican good friend, asking me to try a seaweed drawback. Once a year, Caribbean islands and Mexican coasts are inundated with 30-40 million tonnes of floating sargassum seaweed washing ashore.
Rotting sargassum reasons ecological and economical devastation, destroying livelihoods and the surroundings. I began changing it into fuels and fertilisers, seeking to flip an enormous drawback into a good alternative. Ten years on, I’d turn into a seaweed professional.

I used to be requested to do a podcast at the matter. The presenter, Paddy Estridge, and I chatted about seaweed’s issues, alternatives and doable – and via the tip of it, we have been each beautiful impressed. In combination, we based an organization referred to as SeaGen to harness the facility of seaweed the usage of independent robotics that may seed, domesticate, track and harvest it.

Seaweed holds massive doable to create a extra sustainable long run. However nowadays, this trade lacks the facility to soundly seed, develop, track, harvest and procedure seaweed at scale. Fixing those demanding situations is what SeaGen is all about. We’re designing a collection of automatic robot answers to make considerable, sustainable provide an financial fact.
Our project is some distance from the ones preliminary experiments with the children, however the pleasure and pursuit of data stays the similar. The sticky label chart possibly holds much less attraction to youngsters, however we’ve just about hit 70 other species and I’m at all times at the glance out for the following.
The ones preliminary seaweed samples lead the way for an entire new facet to my analysis portfolio, resulted in hundreds of thousands of kilos in grant investment, and the advent of an organization using a dozen other folks. Now, I’m a part of an international seaweed and robotics revolution.
No longer a foul end result from a stroll alongside the seashore.
