Just 1°C Rise in Temperature of an Antarctic Seafloor Has Drastic Impacts on an Antarctic Seafloor Community

According to the scientists out of the Smithsonian Environmental Research Center and British Antarctic Survey, just 1°C rise ocean temperature may lead in the growth of biological responses under the Antarctic seabed. Intergovernmental Panel on Climate Change (IPCC) predicts that this enables researchers to better understand the association between future warming of the Antarctic Ocean and the biological implications.

Huw Griffiths, a lead author of the British Antarctic Survey (BAS), one of the components of Britain’s Natural Environment Research Council (NERC), said that, “While a few species might thrive at least during the early decades of warming, the future for a whole range of invertebrates from starfish to corals is bleak, and there’s nowhere to swim to, nowhere to hide when you’re sitting on the bottom of the world’s coldest and most southerly ocean and it’s getting warmer by the decade.”

Settled animals in the panels, with including spiral tube worms and colonial bryozoans are very common to all over the seafloors globally. The increment in growth can be supposed as the positive response of ecosystem, there would be instant availability of nutrients to the various species in the food chain. In result, the increased growth skeletally will enhance capturing the carbon in the deep sea floor.

Dr Gail Ashton, the author leading the Rothera’s project whilst, said to the sources that, “This is a deceptively simple and unambiguous experiment. By putting our test plates in the ocean and conducting the experiment there, we’ve changed almost nothing except the water temperature and not the food supply neither light levels, nor the surrounding ecosystem. We can see the impact of temperature change very clearly and it’s quite dramatic.”
