Unlike Antarctica, the Arctic is a vast frozen sea surrounded by land. Here winter is coming to an end but this bleak wilderness remains locked in ice. Eider ducks break the silence. They have stayed here braving the northern winter, instead of flying south to warmer climes. Flocks, 40, 000 strong, sweep across the frozen wastes. They all have the same goal, a polinear, a permanent hole in the sea ice kept open throughout the winter by strong ocean currents. This unusual duck pond provides an overnight sanctuary and when day breaks a rare chance to feed. Just ten metres beneath the ice, the sea floor is carpeted with dense mussel beds. These can only be reached during a brief lull in the currents. The ducks must quickly prise the mussels free before the tide starts to turn. |
