Pancake ice is a form of ice that consists of round pieces of ice with diameters ranging from a few inches to many feet, depending on the local conditions that affect ice formation. It may have a thickness of several inches. Pancake ice features elevated rims with a nearly uniform height of a few inches. The rim is formed by piling the frazil ice/slush/etc. up the edges of pancakes when they collide, both due to random bumping into each other and because of periodic compressions at wave troughs. These rims are the first indication of the onset of the formation of the pancake ice from less consolidated forms of ice.
Pancake ice may be formed in two ways. It may be formed on water covered to some degree in slush, shuga or grease ice. Alternatively, it may be created by breaking ice rind, nilas or even gray ice in the agitated conditions.
Famous quotes containing the word ice:
“He was high and mighty. But the kindest creature to his slaves—and the unfortunate results of his bad ways were not sold, had not to jump over ice blocks. They were kept in full view and provided for handsomely in his will. His wife and daughters in the might of their purity and innocence are supposed never to dream of what is as plain before their eyes as the sunlight, and they play their parts of unsuspecting angels to the letter.”
