At-sea distribution and prey selection of Antarctic petrels and commercial fisheries
Abstract: Commercial fisheries may impact marine ecosystems and affect populations of predators like seabirds. In the Southern Ocean, there is an extensive fishery for Antarctic krill Euphausia superba that is projected to increase further. Comparing distribution and prey selection of fishing

Atlas of top predators from French Southern Territories in the Southern Indian Ocean
Abstract: Penguins, albatrosses, petrels, elephant seals and fur seals are marine top predators that have to come on land to reproduce. Therefore, they are the only marine top predators that can be studied from land base sites, making them the most accessible convenient models to study marine

Large-scale oceanographic fluctuations drive Antarctic petrel survival and reproduction
Abstract: Polar Regions are experiencing environmental changes at unprecedented rates. ese changes can spread throughout entire food webs from lower trophic levels to apex predators. As many top predators forage over large areas, these indirect e ects may be associated with large-scale patterns of

Demographic effects of extreme weather events: snow storms, breeding success, and population growth rate in a long-lived Antarctic seabird
Abstract: Weather extremes are one important element of ongoing climate change, but their impacts are poorly understood because they are, by definition, rare events. If the frequency and severity of extreme weather events increase, there is an urgent need to understand and predict the ecological

Distribution, density and relative abundance of Antarctic krill estimated by maximum likelihood geostatistics on acoustic data collected during commercial fishing operations
Abstract: There is a substantial harvestfor Antarctic krill in the Southern Ocean, butlittle regular scientific monitoring of the resource. Recently, however, the Commission for the Conservation of Marine Living Resources (CCAMLR) has initialised a process to make use of acoustic data from

Using data recorded during commercial krill fishing in Feedback Management
Abstract: Feedback Management (FBM) requires adequate data that can be collected with a minimum of extra effort. Traditional survey practice requires a pre determined survey design that support statistical handling of the collected data into stock abundance information. Godø et al. (2015) (WG-EMM

Multiyear changes in distribution and abundance of Salpa thompsoni in the Western Antarctic Peninsula region
Abstract: The most common and widespread salp in the Southern Ocean is Salpa thompsoni. It is characterized by a circumpolar distribution and its appearance is clearly associated with the occurrence of the Antarctic Circumpolar Current (ACC). This area of the Southern Ocean is characterized by a

Size and stage composition of age class 0 Antarctic krill (Euphausia superba) in the ice-water interface layer during winter/early spring
Abstract: The condition and survival of Antarctic krill (Euphausia superba) strongly depends on sea ice during winter. How krill utilize sea ice depends on several factors such as region and developmental stage. A comprehensive understanding of sea ice habitat use by krill, however, remains
