Another
take on the idea that water turns to vapour when it is considerably warmer
than its surroundings. In this picture, water is being exposed at the
"tide-cracks" that form around offshore rocks and small islands
when the tide rises and falls with continuous sea-ice present. As the ice
is not flexible it cracks and as it does, exposes an amount of open water
to the air. Antarctic sea water varies between about +2°C
and -2°C (the freezing point of sea water) over the course of a year, so
in the case of this picture, the exposed sea water is more than 30°C
warmer than the surrounding air. The result - it begins to turn to a
vapour being so much warmer. The sunshine on this day serves to make it
more visible and different temperature layers in the air cause it to rise
to a band above the clearer air close to the ice surface.
