A growler get its name from the noise it sometimes makes as it bobs up
and down in the sea, not because it is scraping bottom.

A bergy bit is about the size of a house. Both the bergy bit and the
growler are usually calved from icebergs.

I would guess an Ice ridge is were to masses of ice meet and the
pressure forms a ridge.

You got me on the candle Ice.

What is sea ice,
fast ice
shelf ice
ice islands
ice cake
pancake ice
Ice Floes
Ice fields
bending ice
tenting ice
rafting ice
pressure ice
Hummocked ice
weathered ice
pack ice
and last but not least rotten ice
