Acid, alien and hot! Beach visitors to put seaweeds under the spotlight
Beach visitors are being asked to turn scientist this summer to help understand a bit more about the seaside’s unsung hero – seaweed!
The Marine Conservation Society (MCS) has teamed up with the Natural History Museum on a project to get people out on our shores to help study seaweeds. With their 3D structure and multi-coloured forms, seaweeds create shelter and food for an immense diversity of other marine organisms and also support commercial fisheries. But most people don’t give them a second look, and even consider them a slippery nuisance we could do without!
The Big Seaweed Search, a new citizen science project, will help to map out the distribution of seaweeds around Britain. Seaweed distribution and abundance around our coasts is changing. To investigate why this might be and what’s out there, the Big Seaweed Search will try and establish just what is affecting seaweeds on British coasts.
Miranda Krestovnikoff, TV presenter and diver says: “This is a great way to find out more about our beautiful UK seaweeds, and to help researchers track how they are faring in changing environmental conditions. And anyone can join in. At last, seaweeds will get the attention they deserve!”
The seashores and shallow seas around Britain support over 650 species of seaweed, making them globally significant and an important component of British biodiversity. The study will focus on 14 species, to increase our knowledge of how sea temperature increase, sea level rise, impacts of non-native species and increasing acidity are affecting the distribution of different species of seaweed.
“It’s easy to take them for granted, but seaweeds are fascinating, provide shelter and food for an immense variety of marine wildlife, and are of enormous use to humanity”, says Professor Juliet Brodie, of the Natural History Museum. “People are unaware that our daily lives are affected by seaweeds in many ways, from foods and medicines to buffering the effects of rough seas on our vulnerable coastlines”.
In the Big Seaweed Search, eight species of conspicuous wracks (part of the common names of several species of seaweed) have been selected for the public to record. Many of these will probably be familiar, such as bladder wrack, Fucus vesiculosus, with its bladders resembling bubble-wrap that pop underfoot, and knotted wrack, Ascophyllum nodosum, which produces a single egg-like bladder once a year and can live for an estimated 50-60 years.
The study also hopes to unearth more about non-natives and their impact on British coasts. “One of the most well-known ‘aliens’ listed in the study is wireweed, Sargassum muticum, a brown seaweed that was first recorded on the south coast of England in 1973 and has spread very rapidly since then. Another conspicuous non-native seaweed and a favoured food in Japan, Wakame, Undaria pinnatifida, was first recorded in Britain in 1994 on pontoons but is now starting to colonise rocky shores. These ‘aliens’ are here to stay so we need to learn to live with them,” says Juliet.
Justine Millard, MCS Head of Education and Outreach, says the study will establish whether any of these seaweeds are changing in their range, or becoming more or less widespread. “Anyone can be a citizen scientist. We’ll provide simple instructions and an identification guide so that everyone can make a valuable contribution to our knowledge of this important and underappreciated group.”

Until 28 November, prizes worth a massive £10,000 – including experiences, products and tuition – feature in a line-up of items that can be won for £5 in an online prize draw to celebrate Bite-Back Shark & Marine Conservation’s 20th anniversary and help generate crucial funds for the future.
Top of the list of prizes is the chance to spend time with adventurer and wildlife expert Steve Backshall, a workout session with Nat Geo star Aldo Kane, a kayaking trip alongside white-water expert and diver Sal Montgomery and a Zoom call with ‘shark whisperer’ Cristina Zenato.
On top of that, some of the most admired companies in the diving and scuba industry have been quick to support the charity with fabulous prizes that make the £5 ticket price worth more than just a flutter.
Master Liveaboards, BSAC, Midlands Diving Chamber, Go Freediving and Blue Shark Snorkel have all generously donated experience prizes, while celebrated photographer Alex Mustard has donated a print and artists Scott Gleed and Olivier Leger have donated a sculpture and illustration to help boost the fundraising pot.
Fourth Element has donated Ocean Positive gear and LA watch company Nodus has gifted the charity a stunning dive watch. For land lovers, the charity has included a five star London hotel stay at Bankside Hotel plus a family visit to Longleat Safari Park in the roster of prizes.
Campaign director for Bite-Back, Graham Buckingham, said: “We’ve been overwhelmed with support from companies and individuals that we truly admire and who have supported us on our 20 year journey and we’re truly grateful to them all. While we feel incredibly proud of our achievements over the past two decades – and we are super excited about the next chapter – this prize draw isn’t a vanity project. It represents a real lifeline to our work and important advancements in the global protection of sharks. So we hope divers, dive clubs and even bargain hunters grab some tickets to make this a massive success.”
The charity hopes that the prize draw will generate crucial funds to launch a brand new, ground-breaking, campaign to enrol the public and increase support for the protection of sharks around the world.
