Krill of the Ross Sea: distribution, abundance and demography of Euphausia superba and Euphausia crystallorophias during the Italian Antarctic expedition (January–February 2000)
Abstract: Net samples data from the 15th Italian Antarctic Oceanographic Cruise (Jan-Feb 2000) were analysed to obtain a general picture of the summer distribution pattern, abundance and demography of krill in the western Ross Sea (Antarctica). A midwater sampler-trawl (Hamburg Plankton Net) was

Spatial and temporal variability in foraging patterns of krill predators at Signy Island and South Georgia
Abstract: While constrained by the requirement to feed their young, land-based marine predators act as central-placed foragers with movements between their breeding colony and their food resource. In a system where the distribution and abundance of prey is highly variable, foraging behaviour must

Estimating penguin populations using image analysis of colour aerial photography
Abstract: Penguin populations are potentially sensitive indicators of change in the Antarctic and sub-Antarctic and are used extensively to monitor changes in the marine ecosystem. Aerial photographic surveys may provide the most robust method for estimating breeding population size, particularly

Maximum entropy reconstruction of stock distribution and inference of stock density from line-transect acoustic survey data
Abstract: We present a maximum entropy (MaxEnt) method for inferring stock density and mapping distribution from acoustic line-transect data. MaxEnt is founded on the bedrock of probability theory and allows the most efficient possible use of known data in the inference process. The method takes

CCAMLR Survey Database: development during 2002
Abstract: Considerable progress was made on the survey database in early 2002. However, this work had to be postponed because of a higher priority need for developing a web-based data system for the Catch Documentation Scheme. Work on the survey database in 2002 included: • revision of the
