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

Destruction of Antarctic terrestrial ecosystems by a rapidly increasing fur seal population
Abstract: The terrestrial environment of Signy Island, South Orkney Islands, maritime Antarctic, is undergoing rapid and possibly irreversible change caused by a natural biological agent. During the past decade there has been a dramatic increase in the number of Antarctic fur seals Arctocephalus
