What is the Great Atlantic Sargassum Belt, and how might it impact you? 🌊This 5000 mile long wad of floating seaweed hangs out in the Atlantic Ocean and can be seen from space stretching from the Gulf of Mexico all the way to the Congo - and in recent years it has grown larger 🐠In the open sea, this mass of algae is a great habitat for marine life and functions as an excellent carbon sink, 🏝️However when it reaches shallow waters (which it typically will do around May, it’s a bit early this year…) it can smother coral reefs, deplete the water of oxygen resulting in fish death, block intake valves, and prevent boats from passing through 🥚And once it reaches the beach it begins to rot and smell like rotten eggs (hydrogen sulfide) which in high concentrations can cause certain health problems (especially if you’re pregnant) 🪴Ideally it would make an awesome fertilizer or soil amendment like other seaweeds can - BUT sargassum tends to have a higher concentration of heavy metals like arsenic which can make it problematic 📈Now this habitat is important, but the rate it is growing is alarming 🌳It’s fed by an increase in nutrients like phosphorous and nitrogen that come from fertilizer runoff, deforestation, soy farming, and other human activities. And increased flooding from climate change doesn’t really help either. 👩🏼🔬Scientists are working to find solutions, such as sinking it into the deep sea as a form of carbon storage, removing the arsenic and using it for fertilizer, biofuels, or even biodegradable plastics 🤿Tip for you if you see it on your beach - Don’t swim in it - it may have little organisms living in it like jellyfish larvae that may sting you #sargassum #scicomm #marinebiology #environmentalist #sciencenews
