INTERANNUAL SPATIAL VARIABILITY OF KRILL (EUPHAUSIA SUPERBA) INFLUENCES SEABIRD FORAGING BEHAVIOR NEAR ELEPHANT ISLAND, ANTARCTICA
Abstract: We investigate the influence of krill (principally Euphausia superba) patchiness on the ... -2006) during the annual U.S. Antarctic Marine Living Resources (AMLR) program. Standardized strip ... foraging seabirds. The spatial association between krill and predators was influenced by the size and ... concentrated. We conclude that annual patch dynamics of krill strongly influences the local abundance and ...

A small unmanned aerial system for estimating abundance and size of Antarctic predators
Abstract: Quantifying the distribution and abundance of predators is integral to many ecological ... studies, but can be difficult in remote settings such as Antarctica. Recent advances in the development of ... new tool for studying the distribution and abundance of predator populations. We detail our experience ... from the first use of VTOLs for estimating abundance, colony area, and density of krilldependent ...

Beached marine debris surveys and incidences of seabird/marine mammal entanglements and hydrocarbon soiling at Bird Island and King Edward Point, South Georgia, and Signy Island, South Orkneys, 2009/10
previous years, and for the first time we also report data collected at King Edward Point, South Georgia ... (November 2009 to March 2010). Plastic and longline fishing line were the most commonly observed items (in ... varying quantities) at Bird Island, and the majority of items collected at Signy Island were either ... with seabird colonies at Bird Island, with the highest number (97 items; 65%) associated with wandering ...

At-sea distribution and diet of an endangered top predator: links of white-chinned petrels with commercial longline fisheries
French Exclusive Economic Zone (EEZ) and other Commission for the Conservation of Antarctic Marine Living ... Resources areas during the study. We analysed concurrent data on the position of both birds and vessels to ... scale overlap estimates, suggesting that birds and vessels occupy the same overall zone with infrequent ... co-occurrence (19% of birds in the vicinity of vessels). This result was confirmed by the relatively ...

A preliminary stock assessment in SSRUS 486A, G: A Bayesian and CPUE based biomass dynamic model
Abstract: The present report analyses data regarding CPUE, tagging and catch and their ... using multivariate statistical approach of the catch composition. Standardisation of CPUE was done by ... implemented in each species of toothfish. Tagging data was not used in any of the toothfish models, because of ... the low number of recovered individuals and low tag size-overlap. Modelling abundance in both species ...

Incidental seal entanglements on trawl vessels fishing for krill in CCAMLR Subarea 48.3
Abstract: Observers on krill vessels fishing around South Georgia in the 2003 fishing season ... recorded fur seal captures by some krill fishing vessels. These captures can be attributed to the absence ... of effective mitigation measures (escape panels in the nets) and lack of experience of crews new to ... the fishery. Experienced vessels, employing effective mitigation measures, caught no seals. Although ...
