First evidence for a bipolar distribution of dominant freshwater lake bacterioplankton
Read more of: First evidence for a bipolar distribution of dominant freshwater lake bacterioplanktonAs a result of the recent application of DNA based technology to the investigation of maritime Antarctic freshwater lakes, patterns have begun to emerge in the bacterioplankton communities that dominate […]

Influence of a non-uniform velocity field on isochrone geometry along a steady flowline of an ice sheet
Read more of: Influence of a non-uniform velocity field on isochrone geometry along a steady flowline of an ice sheetThe relationship between velocity field and isochrone geometry along a steady flowline of an ice sheet is examined. The method is analytical and based upon the stream function and its […]

New compilation of the Amundsen Sea continental shelf bathymetry
Read more of: New compilation of the Amundsen Sea continental shelf bathymetryThe Amundsen Sea continental shelf is one of the remotest areas of coastal Antarctica, and was relatively unexplored until the 1980s. Over the last two decades, however, oceanographic and geological […]

Till characteristics, genesis and transport beneath Antarctic paleo-ice streams
Read more of: Till characteristics, genesis and transport beneath Antarctic paleo-ice streams[1] Marine geophysical data from the Antarctic continental shelf indicate the former presence of ice streams that drained through bathymetric troughs during the last glacial cycle. Streaming flow is recorded […]

UV-tolerance and instantaneous physiological stress responses of two Antarctic amphipod species Gondogeneia antarctica and Djerboa furcipes during exposure to UV radiation
Read more of: UV-tolerance and instantaneous physiological stress responses of two Antarctic amphipod species Gondogeneia antarctica and Djerboa furcipes during exposure to UV radiationWe investigated the shielding against solar ultraviolet radiation and inducible damage, as well as the short-term response of whole animal metabolic rate in two Antarctic shallow water amphipod species. Light […]

Bathymetry of the Amundsen Sea continental shelf: implications for geology, oceanography, and glaciology
Read more of: Bathymetry of the Amundsen Sea continental shelf: implications for geology, oceanography, and glaciologyThe Amundsen Sea continental shelf is one of the most remote areas of coastal Antarctica and was relatively unexplored until the late 1980s. Over the last two decades, increased oceanographic […]

Paradigm misplaced? Antarctic marine ecosystems are affected by climate change as well as biological processes and harvesting
Read more of: Paradigm misplaced? Antarctic marine ecosystems are affected by climate change as well as biological processes and harvestingA recent review by Ainley et al. has suggested that recent investigations of the ecological structure and processes of the Southern Ocean have “almost exclusively taken a bottom-up, forcing-by-physical-processes approach […]

Reconciling complexity with stability in naturally assembling food webs
Read more of: Reconciling complexity with stability in naturally assembling food websUnderstanding how complex food webs assemble through time is fundamental both for ecological theory and for the development of sustainable strategies of ecosystem conservation and restoration. The build-up of complexity […]
