Every year icebergs drift down to Newfoundland shores from Greenland. Last week Stan and myself paddled by this one in Bay Bulls. Its the first time I've seen a blue line like this in an iceberg and there was some question how it formed.Icebergs are white because air gets trapped in the snow as it falls and remains trapped as the snow compresses under weight to form into ice. The air bubbles caught in the ice reflect white light.
I thought the blue line was formed by icewater refreezing in a fissure in the ice. The icewater contains less air like ice that forms on a pond or lake, which you can see through if its not too thick. Like an icecube. In any case it was pretty cool - literally and figuratively.
