Furthermore, altered diving patterns suggest southern elephant seals have to work harder for food within a warming Southern Ocean (16).
Not only single species, but whole communities can be affected by climate change (17).
This happens with increases in iceberg scouring, glacier retreat, and changes in sea-ice cover (18, 19).

Iceberg Damage to Seafloor Increases

Worms, sea spiders, urchins and other creatures that dwell on the Antarctic seafloor are pounded daily by icebergs scraping up their homes.

Icebergs are large chunks of ice that have broken off from a glacier or ice shelf and float in open water. As they float, pushed around by winds and tides, their bottoms, which can sometimes reach to a depth of 1,600 feet (500 meters), scour the seafloor beneath them.
