What is the Arctic Ocean marine ecoregion?
The Arctic Ocean is one of the coldest seas on Earth, with thick ice on the surface. In winter it stays dark for months, but in summer the sun shines all day and algae bloom under the ice. Openings in the ice, called leads and polynyas, let light and air into the water. Northern lights and rapid warming make this icy ocean both magical and fragile.
