| Summary: | The central hypothesis of the Palmer LTER program is thatvariability in t annual cycle of sea ice will ffect t e structure and functioning of the marine pelagic ecosystem in the Antarctic. This annual advance and retreat affects a large area of the southern oceans, including all of the continental shelf. To address some specific questions on the effect of sea ice on the winter ecology of the pelagic ecosystem, the Palmer LTER conducted a pair of cruises in 1993 to compare pre- and postwinter characteristics of various aspects of the system. The cruise objectives included the following: • documenting seasonal variability in processes of both pri mary and secondary production in the water column within the Palmer LTER study region by comparing abun dance, distribution, and rates found in August 1993 (winter) to those found during both the previous January (summer) |
