Field Surveys

The AMLR Program attempts to assess the status of Southern Ocean krill and finfish populations, and their predators, by conducting annual multi-faceted collaborative in situ research studies.  To this end, the AERD utilizes an AMLR-chartered research vessel to conduct predator/prey studies in the vicinity of two field stations in the South Shetland Islands.  The vessel platform is used primarily to collect environmental, oceanographic, primary productivity and prShown here are the tracklines (green line) followed by the R/V Yuzhmorgeologiya.  Each green dot represents a station at which the AERD conducts CTD casts.  Also shown (red stars) are the lcoations of the two field stations where predator studies are conducted.ey data (zooplankton abundance and distribution, specifically Antarctic krill Euphausia superba).

Concurrently, the AMLR Program collects predator data at the field stations located at Cape Shirreff on Livingston Island (seabird and seal studies) and at Copacabana in Admiralty Bay (jointly funded by the National Science Foundation/Office of Polar ProgramsThe previous link is a link to Non-Federal government web site.

Finfish surveys are conducted periodically to assess biomass of species subject to commercial harvesting.
