Detection of growth zones in the eyestalk of the Antarctic krill Euphausia superba (Dana, 1852) (Euphausiacea)
Abstract: No reliable measures of age currently exist in the Antarctic krill, Euphausia superba (Dana, 1852). The eyestalks from 51 individuals were dissected, cut in longitudinal sections and studied for identifying growth zones. The krill was collected at the South Orkney Islands during January

The winter pack-ice zone provides a sheltered but food-poor habitat for larval Antarctic krill
Abstract: A dominant Antarctic ecological paradigm suggests that winter sea ice is generally the main feeding ground for krill larvae. Observations from our winter cruise to the southwest Atlantic sector of the Southern Ocean contradict this view and present the first evidence that the pack-ice

RECENT TRENDS IN NUMBERS OF FOUR SPECIES OF PENGUINS AT THE PRINCE EDWARD ISLANDS
Abstract: Four species of penguin breed regularly at South Africa’s Prince Edward Islands: king penguin Aptenodytes patagonicus, gentoo penguin Pygoscelis papua, macaroni penguin Eudyptes chrysolophus and southern rockhopper penguin E. chrysocome. In December 2008 it was estimated that some 65 000

Beach litter survey, Signy Island, South Orkney Islands 1994/95
Abstract: A beach litter survey was carried out on Signy Island, South Orkney Islands during the 1994/95 austral summer. Similar surveys were carried out during the four previous summers. Debris was cleared from three study beaches, Foca Cove, Cummings Cove and Starfish Cove, in December 1994, and

Revised research plan for the 2015/16 exploratory longline fishery of Dissostichus spp. in Subarea 48.6
Abstract: The current season (2014/15) is the final one of the first three-season research which began in 2013 in data-poor fisheries. In the present report, the next three-season (2016-18) research plan in Subarea 48.6 was revised using the updated CCAMLR C2 and Observer data. The stock sizes for
