Came across these two rather nice aerial photos of sea ice off the coast of East Greenland -- just to give us some idea of the almost infinite variety found in nature.
The top photo shows very thin plates of ice -- maybe just a few inches thick -- with rafting occurring under the influence of winds and currents. The slabs are literally sliding over one another.
The lower pic is of old shorefast ice which is breaking up into discrete floes -- this can be a foot or more thick. Note that in some areas there have been so many collisions between the floes that there is a lot of brash ice. But there is no glacier material here. All the ice in both photos has come from the direct freezing of sea water.
