Fish populations of Port Foster, Deception Island, Antarctica and vicinity
The fish populations of Port Foster, Deception Island, South Shetland Islands, Antarctica, were investigated as part of the Erupt Antarctic ecosystem study. Surveys were conducted on five cruises between March 1999 and November 2000. Samples also were collected off Livingston Island and King George...
