Plans for a multi-national coordinated investigation focusing on the krill-based ecosystem in Area 48 during the 2015-16 austral summer
Abstract: This paper outlines plans for a co-ordinated, multi-national study focusing on the krill-based ecosystem in Area 48 during the 2015-16 austral summer. The studies will include at-sea data collection from research and fishing vessels, together with remotely sensed data obtained from

Winter distribution and condition of Antarctic krill in relation to sea-ice and water column production in the South Shetland Islands during Austral Winter 2013
Abstract: Acoustic and net sampling of Antarctic Krill and other euphausiids was conducted at 88 stations around the South Shetland Islands during a 30 day cruise between 10 August and 9 September 2013. Abundance and demographic patterns revealed that Antarctic krill were concentrated in the

Assessment of escape mortality of Antarctic krill (Euphausia superba) in trawls
Abstract: The overall purpose of this study was to estimate the mortality rate of Antarctic krill (Euphausia superba) that escape from the most common mesh size used in the current commercial fishery. The experiment was carried out on the krill fishing grounds off South Orkney Islands (60°35’S, 45

Development in maturity stage composition and vertical distribution in an Antarctic krill (Euphausia superba) hotspot
Abstract: Antarctic krill (Euphausia superba) aggregate in various ways depending on a range of factors, from biological (e.g. antipredatory behavior, social interactions and food availability) to physical forcing (e.g. advection and retention). Some areas, often associated with topographical

Report from the annual survey of Antarctic krill and apex predators distribution at South Orkney Islands in 2014, and assessing escape mortality of krill in trawls
Abstract: This report describes the work and preliminary results from the fourth annual survey conducted around the South Orkney Islands, using a commercial krill fishing vessel as research platform. The overall purpose is to describe taxonomy of the macrozooplankton community, demography and

Risk maps for Antarctic krill under projected Southern Ocean acidification
Abstract: The embryonic development of Antarctic krill (Euphausia superba) is sensitive to elevated seawater CO 2 levels and successful hatching is impaired at CO 2 levels greater than 1000 μatm. Exposure to elevated CO 2 during the first 3 days of embryonic development significantly retards

Review of the Russian marine researches in the south-eastern part of the Atlantic Antarctic Area (20°W–30°E)
Abstract: The review of Russian expeditions carried out during 1970-2000 in the south-eastern part of the Atlantic Antarctic Area was discussed. Distribution of krill with reference to the structure and dynamics of the water masses, species dominated in Phytoplankton and Ichthyofauna were analyzed

Background and criteria of establishment of Marine Protected Area (MPA) in the Weddell Sea
Abstract: Present work contains considerations and proposals of possible joint research of Russian and German scientists in the eastern part of the Weddell Sea. Data on potentially valuable for commercial fishing species in the eastern part of the Weddell Sea collected by German investigators in

Composition of Leucocytes in Peripheral Blood of Antarctic Toothfish Dissostichus mawsoni (Nototheniidae)
Abstract: The aim of the work is to study the leukocyte composition in blood of deep-water fish species by the example of Antarctic toothfish Dissostichus mawsoni. Fish were caught in January–February 2012 in the Ross Sea (Statistical Subarea 88.1) at depths from 690 to 1183 m from onboard “Yantar

Expanding Antarctic seabird monitoring in east Antarctica using a remote camera network: potential use for monitoring for feedback management
Abstract: Antarctic seabirds are important indicators of impacts and change in Southern Ocean ecosystems, but their isolated and remote breeding populations are challenging and expensive to assess and monitor using traditional methods. Remotely-operating time-lapse cameras offer a tool for cost
