Distribution of Antarctic krill and dominant zooplankton west of the Antarctic Peninsula

R. M. Ross, L. B. Quetin, and C. M. Lascara

The horizontal and vertical distributions of selected taxa that dominate the pelagic Zooplankton community (>0.2 mm) within the Palmer Long-Term Ecological Research (LTER) study region are described. In addition to a synthesis of existing published descriptions for euphausiids, salps, and copepods, two newly available datasets are analyzed. Recent observations (1991–1994) obtained as part of the Palmer LTER program are used to provide new information on the seasonal and interannual distribution and abundance of the salp, Salpa thompsonii. Acoustic data collected during a series of twelve cruises conducted in the late 1980s are used to describe seasonal differences in the geographic distribution and the dimensional character (length, height, volume, depth) of krill (Euphausia superba) aggregations along the west coast of the Antarctic Peninsula.
