Ross Sea Ice Cover Decay Watch

Sea Ice Concentration Color Bar Today's Ross Sea ice cover

The sea ice cover in the Ross Sea is particularly interesting in the melt season. In the Arctic ocean, the ice cover generally decays from the edge inward. In much of the Antarctic, there is a more or less steady decay of the ice cover across the whole region (see the animations on for November through February each year). In the Ross Sea, the ice cover decays from the north (the warm side, remember this is the southern hemisphere) and from the coast outwards. While this happens in certain other parts of the Antarctic as well, it is especially strong in the Ross Sea.
