The Water Flows Into The Southern Ocean
The Southern Ocean surrounds much of Antarctica and contains many kinds of polar wildlife, including whales, seals, and micro-organisms. The Southern Ocean is full of icebergs that have broken off of Antarctic glaciers and ice sheets, so it can be complicated for a ship to navigate.
The water in the subglacial lakes of Antarctica flows in such a way that it pools together and streams down, underneath the glaciers, into the Southern Ocean. This freshwater that flows into a salty ocean has some impact on coastal wildlife, and the effects are something that researchers are trying to understand.
