1. DETECTION OF VULNERABLE MARINE ECOSYSTEMS IN THE SOUTHERN SCOTIA ARC (CCAMLR SUBAREAS 48.1 AND 48.2) THROUGH RESEARCH BOTTOM TRAWL SAMPLING AND UNDERWATER IMAGERY

   Abstract:  High densities of vulnerable marine ecosystem (VME) indicator taxa were encountered in 17 areas off the northern Antarctic Peninsula and 11 areas off the South Orkney Islands (CCAMLR Subareas 48.1 and 48.2). These areas, which have been proposed for inclusion in the CCAMLR VME registry,

2. DEMOGRAPHIC PATTERNS OF ANTARCTIC KRILL (EUPHAUSIA SUPERBA) EXPLAIN THE SPATIAL SEGREGATION OF BALEEN WHALES (MYSTICETI) AROUND THE SOUTH SHETLAND ISLANDS, ANTARCTICA

   Abstract:  Using data collected by U.S. Antarctic Marine Living Resources (AMLR) Program during January surveys 2003 to 2007, we examine the spatial relationships between baleen whale distributions and Antarctic krill (Euphausia superba) abundance and demography near the South Shetland Islands

3. RAPID CLIMATE CHANGE AND LIFE HISTORY: HOW PLASTIC IS THE ADÉLIE PENGUIN?

   Abstract:  Climate change in the Antarctic is having major impacts on physical and biological systems. For the Adélie penguin, which breeds around Antarctica, different populations have been subject to different environmental conditions over space and time. To assess the ability of the Adélie

4. PREDICTING THE VULNERABILITY OF BENTHIC, HABITAT-FORMING ORGANISMS TO DISTURBANCE USING LIFE-HISTORY CHARACTERISTICS

   Abstract:  Assessing the impacts of fishing on Vulnerable Marine Ecosystems (VMEs) in the Southern Ocean is hampered by the paucity of information on the resistance and resilience of these ecosystems to disturbance. Both resistance and resilience of individual VME-forming taxa are related to their

5. ON THE STRATOSPHERE OZONE DISTRIBUTION ASYMMETRY POSSIBLE IMPACT ON KRILL BASED ECOSYSTEM

   Abstract:  Besides the climate change impact on krill based ecosystem uncertainties the factors of the ozone distribution asymmetry influence over South Ocean is discussed. The existence of the considerable zonal asymmetry in total ozone distribution over Antarctica due to the planetary waves in a

6. An Apparent Decrease in the Prevalence of “Ross Sea Killer Whales” in the Southern Ross Sea

   Abstract:  Killer whales (Orcinus orca), both ecotype-B and-C, are important to the Ross Sea, Antarctic ecosystem; the type-C is referred to as “Ross Sea [RS] killer whale”. Herein, we review data on occurrence patterns and diet of RS killer whales, and present new information on numbers observed

7. The importance of Antarctic Toothfish as prey of Weddell Seals in the Ross Sea: a Review

   Abstract:  Uncertainty exists over the importance of Antarctic toothfish (Dissostichus mawsoni) as prey of top predators in the Ross Sea. We herein assess relative weight given to direct, observational evidence of prey taken, as opposed to indirect evidence from scat and biochemical analysis, and

8. A history of the exploitation of the Ross Sea, Antarctica

   Abstract:  Recent analyses of anthropogenic impacts to marine systems have shown the Ross Sea to be the least affected stretch of ocean on Earth, although historical effects were not included in the study. Herein the literature is reviewed to quantify the extent of extraction of biological

9. Impacts of cetaceans on the structure of Southern Ocean food webs

   Abstract:  Here we present three scenarios that demonstrate how cetaceans may influence the structure and dynamics of the Southern Ocean food web. These should be considered in addition to several other examples recently identified, and reviewed herein. Marine trophic cascades resulting from top

10. QUANTIFYING MOVEMENT BEHAVIOUR OF VESSELS IN THE ANTARCTIC KRILL FISHERY

    Abstract:  Ten years of recent finescale haul-by-haul krill data were used to characterize the behaviour of the krill fishery. Analysis of distance between hauls in relation to their catch level revealed a distinct pattern. Mean between-haul distances were generally longer when catch levels fell
