Photos: Greenpeace Collects Plastic In Sargasso

Greenpeace campaigners collected more than 300 plastic pieces during a five-day expedition in the Sargasso Sea.

A spokesperson said, “Campaigners from Greenpeace UK have retrieved hundreds of pieces of plastic from clusters of seaweed floating in the Sargasso Sea in the Atlantic Ocean. They spent the last five days on board the Arctic Sunrise crossing the sea to launch a campaign to create a global network of marine sanctuaries under the Global Ocean Treaty.

“The ship crew made an unplanned stop to look inside a patch of sargassum seaweed – the golden algae that forms gigantic floating mats and gives the Sargasso Sea its name. Although this was a comparatively small mat, they retrieved more than 300 pieces of plastic in just 30 minutes including bottle caps, disposable lighters, buoys, shoes, childrens’ toys and dozens of smaller scraps in the process of breaking down into microplastics.”

Briony Venn, oceans campaigner for Greenpeace UK, said, “As soon as the sargassum came into view from the ship’s bridge, we saw large pieces of plastic debris tangled inside it. On closer inspection, every clump of seaweed contained a panoply of plastic pollution, from bottle caps to disposable cutlery.

“Plastic is just one of the threats facing the Sargasso along with industrial fishing, increased shipping and climate change. The UK has an opportunity to help protect this golden floating rainforest by ratifying the Global Ocean Treaty as soon as possible, and by working with other governments to champion the Sargasso Sea as the world’s first high seas ocean sanctuary under the Treaty.”

The spokesperson said, “The sargassum species of seaweed is unique to the Sargasso Sea where it provides a vital habitat for 10 species of crab, fish, shrimp and other creatures that are found nowhere else. It also provides a nursery for baby sea turtles and a vital source of food for seabirds on their epic migrations across the Atlantic Ocean.

“The crew also stopped to pull a metre-wide tangle of ‘ghost gear’ – discarded rope and fishing gear – from the water where it could have snarled sea turtles, seabirds and other marine animals.

“This first leg of the voyage has helped to document the vast array of animals living in the Sargasso. The crew recorded humpback and pilot whales, dolphins and a wide variety of fish and seabirds. At one point, a pod of at least 20 pilot whales surrounded the ship, and several humpback whales accompanied the Arctic Sunrise into Bermuda.

“The crew also used a hydrophone – an underwater microphone – and DNA sampling techniques to provide insights into the distribution and migration patterns of whales, dolphins and other marine animals. Two seabird conservationists from Bermuda joined the voyage and recorded more than 10 species including some frequent visitors to the UK such as Manx and Great Shearwaters, Leach’s Petrels and Arctic Skuas.

“Industrial fishing fleets pose a major threat to marine ecosystems like this because they drag longlines through the sea which inadvertently hook marine mammals, turtles, seabirds and sharks. Increased shipping and the prospect of deep sea mining also cast a shadow over the future of this ecosystem.

“Since most of the Sargasso Sea lies in the high seas, outside national borders, tools for restricting human activity here have been extremely limited. The Global Ocean Treaty agreed in March last year makes it possible for governments to create sanctuaries on the high seas – like national parks at sea – where marine life can recover and thrive.

“Greenpeace UK is calling on the UK government to ratify this Treaty into national law before the General Election, and to work with other governments in the region to propose the Sargasso Sea as the world’s first high seas sanctuary under the Treaty. This, alongside a Global Plastics Treaty that cuts plastic production and ends single-use plastic, would go a long way towards protecting the sea.”
