Summary
Over the last 20 years, the AERD has observed that the decline in sea-ice extent and duration has resulted in not only a decline in krill, but also fundamental changes to the mechanisms governing the environment around the South Shetland Islands. As annual sea ice extent and duration decline and ice is less prevalent each decade, the productivity of the ecosystem becomes controlled by other atmospheric forcing affecting the temperature and currents in the ocean and the amount of nutrients in the water.

Annual surveys vary between austral summers and winters. Land based studies are focused on austral summer (roughly late October through early March). Vessel based surveys are normally conducted in the austral summer (January through March), however in recent years, surveys have been conducted in the austral winter (August/September time frame) to accommodate over winter studies.

| Abstract: |
Over the last 20 years, the AERD has observed that the decline in sea-ice extent and duration has resulted in not only a decline in krill, but also fundamental changes to the mechanisms governing the environment around the South Shetland Islands. As annual sea ice extent and duration decline and ice is less prevalent each decade, the productivity of the ecosystem becomes controlled by other atmospheric forcing affecting the temperature and currents in the ocean and the amount of nutrients in the water. |
| Purpose: |
The Antarctic Marine Living Resources (AMLR) Convention Act of 1984 provided the legislative authority to establish the U.S. AMLR Program. This national program provides information needed for the development and support of U.S. policy regarding the conservation and management of the marine living resources in the ocean areas surrounding Antarctica. |
| Other Citation Details: |
The datasets incorporated into this archive have been collected by researchers affiliated with the U.S. Antarctic Marine Living Resources (AMLR) Program under the National Marine Fisheries Service (NMFS). These data are part of a long term ecosystem project centered on the South Shetland Islands off the Antarctic Peninsula, Antarctica. Funding for this project was from the NMFS AMLR Program. Data were collected from land and ship based platforms. |
