Sargassum seaweed was recorded as far back as the 15th century when Christopher Columbus wrote in his expedition diaries about miles and miles and miles of dense seaweed as he crossed the Atlantic Ocean. In 2011, a great mass of this seaweed emerged, stretching from West Africa to the Gulf of Mexico, a phenomenon known as the Great Atlantic Sargassum Belt. Since then it’s been washing up on coastlines in massive amounts, causing a big impact on communities whose economy relies heavily on the tourism industry. As the seaweed decays it releases hydrogen sulphide which has a strong odour of rotten eggs.Various research projects are looking into ways of containing this seaweed, as no one has found a viable solution on an industrial scale. But whilst it is causing problems onshore, offshore in the deep ocean of the Sargasso Sea, the sargassum provides a unique ecosystem for a variety of marine life including turtles and swordfish.So, this week on The Inquiry we’re asking, ‘What’s going on with sargassum seawee
