By 2100 in the oceans will not a shells, the concentration of acid in the waters of the oceans is growing much faster, than previously thought- VIDEO

In the Nature Geoscience appeared an article of scientists from the British National Antarctic Research Centre in Cambridge, UK, under the leadership of Geraint Tarling, that the concentration of acid in the ocean is growing much faster, than previously believed. According to Geraint Tarling, speed increase of concentration of acids in the ocean were found with acidic "scars" on the shells of Limacina helicina antarctica, invertebrate gastropods. According to scientists of British National Centre for Antarctic Research, Cambridge, water oceans absorb a most of the carbon dioxide from human activities, and an increased concentration of carbon dioxide in the water dissolves the shells of marine organisms, which use lime as the primary building material for the hulls of their shells . Sinks anglerfish species Limacina helicina Antarctica, which have been studied in Scotia Sea aboard on the oceanographic vessel "James Clark Ross", consist of the particularly sensitive to acid mineral - aragonite, which begins to dissolve even with a small increase in the concentration of CO2 in the water, so the dissolution of shells Limacina helicina Antarctica is the first sign of a more global phenomenon, and if the trend does not change, already in 2100 the inhabitants of the seas can lose a shells, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... hells.html
