The Ice Mosaic is a region of the North Coast of Canada, in the Arctic Ocean, where pieces of ice are small and thin, allowing sunlight to stream through into the water below. The small pieces and puzzle-like formation of the pieces create what resembles a mosaic. This beautiful area is part of the swimming pattern of the White Mother, once you find her, and is also patrolled by one of the several Greenland Sharks in the region. Blue Whales can be found here as well.
In the diver's notebook, the area is described:
"Found in the center of the Northern Canadian coastal sea, this area is known for the beauty of the sunlight that seeps through the cracks between sheets of ice. A group of narwhals lives east of the area."
