Rivers of Brine in Antarctic Sea Ice Provide Homes for Tiny Organisms
Antarctic sea ice is more than just frozen seawater at the ocean surface. It is an important home for many tiny-sized marine organisms! When seawater freezes, tiny salty rivers and streams form inside the sea ice. These are called brine channels. To live in these channels, organisms must be smaller...
