Scientists discover ocean current between northern and southern hemispheres

A comparison of Antarctic cores with cores from Greenland proves a north-south link and indicates a meridional overturning circulation, or the Atlantic Conveyor, in the process of heat transfer, according to studies carried out by scientists from 10 European countries working on the European Project for Ice Coring in Antarctica (EPICA).

Team leader and paleoclimatologist Hubertus Fischer from the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven, Germany, writes in the current issue of Nature that it is really astounding how systematic this process worked even for smaller temperature changes in the Antarctic.
