United States seabird research undertaken as part of the CCAMLR Ecosystem Monitoring Program, 1987–1988
Abstract: As part of the NMFS/AMLR program to provide information for the effective management of Antarctica’s marine living resources, three permanent monitoring sites were established on the western side of the Antarctic Peninsula. Listed from north to south, these were Seal Island (Elephant

Preliminary report of the 1987–1988 NMFS Antarctic Marine Living Resources Program Marine Mammal and Bird Field Research
Abstract: The report describes the land based ecosystem monitoring studies conducted in three separate areas of the Antarctic Peninsula marine mammal s and birds. In addition, a joint U.S./Chilean cruise to track fu r seals and penguins at sea is described. Author(s): United States of America

Physical oceanographic setting of the Siedlecki January 1987, South Shetland Island data set
Abstract: In the vicinity of the northern tip of Antarctic Peninsula, the Bransfield Straits and South Shetland Islands, cold polar waters from the Weddell Sea meet warmer circumpolar water from the Pacific Ocean. A series of fronts form which collectively are referred to as the Weddell-Scotia

Patterns and processes in the distribution and dynamics of Antarctic krill
Abstract: A general framework is presented to develop, test and integrate component models of the distribution and dynamics of Antarctic krill population at various spatial and temporal scales. We suggest that models of increasing complexity be developed iteratively for variability and patchiness

Joint Polish/American hydroacoustic survey of Elephant Island in the vicinity of King George Island, 1988
Abstract: The hydroacoustic survey found a low krill abundance in most areas covered by last years survey. The total biomass in the vicinity of Elephant Island was estimated from 120 kHz data to be 260 k tons and that in the Bransfield Strait South of King George Island was 39 k tons for a total

Statistical problems in krill stock hydroacoustic assessments
Abstract: Two primary issues are at question for hydroacoustic assessments of krill, The first is the methods applied to establish biomass in a survey area and the second is the improvement in accuracy of target-strength measurements. In the case of statistical methods, there are no clear

Acoustic data analysis and models of krill spatial distribution
Abstract: Acoustic data obtained on the 4-5 January 1987 aboard the R/V Professor Siedlecki were used in three descriptors of krill spatial aggregation: power spectra for krill biomass fluctuations in space, semivariogram (spatial autocorrelation of krill biomass) and the frequency distribution of

Distribution of phytoplankton in the mixed layer: implication of krill abundance
Abstract: The vertical trajectory of phytoplankton in the Antarctic ocean is modelled as a random walk with a diffusivity derived from a simple Ekman layer model and turbulence theory. The surface mixing layer is shallow, but diffusion is large enough to effect the vertical distribution of
