"The ice-field begins in late summer as young ice in Baffin Bay. Slowly it moves south. In November off Labrador the sea is dappled by small circular pieces of ice that have been chopped and crushed to a snowy consistency by wind and sea. Under winter's encouragement this grows rapidly into blocks six to ten feet in diameter, a lovely translucent green with white edges created by constant grinding against other pans. This is known to mariners and sealers as slob ice. On calm winter nights off the Labrador coast the sea freezes until these blocks are embedded in large sheets of ice that may be several miles in length, but are constantly forming and reforming under pressure of sea and wind. This becomes the sheet ice that is the home of the whelping seals." --Cassie Brown with Harold Horwood, Death on the Ice: The Great Newfoundland Sealing Disaster of 1914, Doubleday Canada, 1972.
