Meltwater from ice caps may divert the Gulf Stream

Scientists fear huge volumes of meltwater from diminishing ice caps may divert the Gulf Stream

Why build-up of fresh water in Arctic could spell trouble for Britain

By Steve Connor, Science Editor

In the Canada Basin area of the Arctic to the west of Greenland, for instance, scientists are monitoring a huge pool of icy meltwater more than 7,500 cubic kilometres in size, which is about twice the volume of Africa's Lake Victoria. This pool of cold freshwater, which is less dense than the saltier seawater on which it floats, is being kept in its place by circulating winds.

The scientists are concerned that a sudden change in wind patterns might send this fresher water south via the Labrador Current into the North Atlantic where it could interfere with the complex "thermohaline" ocean circulation. These currents, which keep the warm Gulf Stream flowing towards Britain and the rest of north-west Europe, flow between the sea surface and the seabed and are controlled by the relative saltiness of seawater.

"In the past we know that a sudden change in Atlantic currents has happened because of a relatively sudden release of freshwater into the North Atlantic. We can imagine that it could happen again," said Benjamin Rabe, of Germany's Alfred Wegener Institute for Polar and Marine Research in Bremerhaven.
