Southern ocean

The Southern Ocean is cold and windy with a short, warmer summer. Living things here have plenty of water but perhaps more salt than they need.

Animals that live in the air or on the land use the small islands in the area. There is frantic activity in the brief summer as they eat, mate and prepare for winter.

Things that live in the sea can rely on an environment with a constant temperature and salt level. Their main problems are finding food and each other in all that water!

Vegetation

Large tussock grasses, dwarf plants and mosses are common on Southern Ocean islands. Constant wind and low temperature prevents the growth of taller trees. Beds of kelp grow in the shallow waters surrounding the islands. The deeper ocean can only sustain microscopic, floating, single-celled plants called phytoplankton.
