1. 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

2. 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

3. 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

4. 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

5. 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

6. DIRECT EFFECTS OF CLIMATE CHANGE ON THE ANTARCTIC KRILL FISHERY

   Abstract:  Climate change is predicted to affect marine fisheries but these effects are usually thought of as being indirect, for example through distributional changes of fish populations, changes in marine biodiversity or changes in oceanic productivity. We show that in Antarctic waters there is

7. FIRST EXPERIMENTAL SETTINGS OF DEEPWATER VERTICAL LONGLINES IN THE ANTARCTIC TOOTHFISH FISHERY DISSOSTICHUS MAWSONI NORMAN, 1937 (PERCIFORMES, NOTOTHENIIDAE) IN THE AMUNDSEN SEA

   Abstract:  For the first time in the history of deepwater longline fishing on Antarctic toothfish Dissostichus mawsoni (Norman, 1937) the experimental settings of deepwater vertical longlines was made from the Russian longliner Yantar in March, 2008 in the Amundsen Sea (subarea 88.2,D of the

8. REPORT OF THE UK GROUNDFISH SURVEY AT SOUTH GEORGIA (CCAMLR SUB-AREA 48.3) IN JANUARY 2009

   Abstract:  In January 2009 the UK undertook a bottom trawl survey of CCAMLR Sub-area 48.3 on the FV Sil. A total of 71 random and representative 30 min tows were made giving good geographic coverage. The estimated mean biomass of Mackerel icefish (Champsocephalus gunnari) calculated using 10 strata

10. BOOK REVIEW: WHALES OF THE SOUTHERN HEMISPHERE: BIOLOGY, WHALING, AND PERSPECTIVES OF POPULATION RECOVERY by Y. A. Mikhalev

    Abstract:  Examined the distribution and migration patterns of whales in the Southern Hemisphere. The presence of a new species of killer whale in the Antarctic, Orcinus nana, is shown. The impacts of extermination of whales in the Antarctic ecosystem are examined. Regions are defined which could
