An ocean is the last place you’d expect to find a freshwater lake. As strange as it may seem, the Arctic Ocean is home to a lake roughly twice the size of Lake Victoria, one of the largest freshwater lakes in the world. This arctic lake is located in the Beaufort Gyre, an area near northwestern Canada where the water circulates in a clockwise pattern. Normally, as rivers empty into an ocean, fresh water mixes with the salty ocean water. Over the last decade, scientists have discovered that arctic river water and melting sea ice have pooled with little mixing. The growing pond isn’t entirely salt free, but its size and stability have scientists worried.
