Sparteye, I'm supposed to be working! But you tempt me to look up too many things. In this case, Newfoundland words for ice-related things, all of which I've heard but since I don't actually work on the sea I looked up the definitions for accuracy:

ice pans - seem to be like your pancakes
copying - jumping from pan to pan (rather dangerous, but used to be a childrens' pastime)
growler -"Piece of floating ice esp hazardous to vessels because of its instability or indeterminate size." (Dictionary of Nfld. English)
bergy bit - "large chunk of glacier ice (a very small iceberg) floating in the sea" (All About...Glaciers)
slob ice - "Heavy, slushy, densely packed mass of ice fragments, snow and freezing water, esp. on the surface of the sea; sludge" (Dictionary of Nfld. English)
