Mercury (Hg) is a toxic heavy metal that changes into various chemical forms through geochemical processes. It is an element that occurs naturally in the environment but with industrialization, humans have altered its cycle by adding more mercury in the water, air, and soil.
Coral Harbour is on the southern shore of Southampton Island, on the northern rim of Hudson Bay. The Inuktitut name for the community is Salliq, "large flat island in front of the mainland," while the English name refers to the fossilized coral found in the harbour.
Coral Harbour is one of the best places in Nunavut to see marine wildlife. The nearby Coates Island is a resting place for colonies of walruses. Two bird sanctuaries, the East Bay Migratory Bird Sanctuary and the Harry Gibbons Migratory Bird Sanctuary are famed for bird watchers. Thousands of snow geese, as well as tundra swans, sandhill cranes and other species migrate to the area in spring. Local outfitters offer boat tours to view the wildlife in the area.
