German environmental specialists have revealed that major changes are taking place in the water system of Arctic Ocean.
It was a very isolated ecosystem but recently the matters have started to change. Due to global warming and thawing ice new tendencies in water exchange are developing. By examining the rock at the bottom of Arctic Ocean, the environmental scientists have found exact data about water exchange during the last 15 million years
It is surprising that during those millions of years the lower layers of Arctic Ocean have been generating the water locally (within the Arctic circle of latitude), whereas now the water starts coming in from Atlantic Ocean via the strip between Greenland and Svalbar. The top layer of Arctic Ocean receives freshwater from the large rivers of Russia.
German ecologists believe that this is due to global warming and possibly the streams of “outside” water would eventually undermine the fragile ecosystem of the smallest of the Earth’s oceans.
