The effects of chilling (to temperatures above the supercooling point, SCP) and freezing on respiration of adults and larvae of two coleopterans living on sub-Antarctic South Georgia (54°S, 37°W),Hydromedion sparsutumandPerimylops […]
Ecophysiological features, including survival and recovery from freezing and determination of the freezable water content, are reported for a cold-adapted cockroach Celatoblatta quinquemaculata Johns 1966 (Dictyoptera, Blattidae) inhabiting alpine communities […]
New multifold seismic‐reflection and wide‐angle reflection/refraction data across George VI Sound, Antarctic Peninsula, show the presence of graben and horst structures indicating an extensional origin. The data suggest that rocks […]
The seasonality of polypide cycling has been investigated for three species of erect bryozoans from Antarctica: Isoseculiflustra rubefacta (Kluge, 1914), Nematoflustra flagellata (Waters, 1904) and Himantozoum antarcticum (Calvet, 1905). Approximately […]
The cheilostome bryozoan Fenestrulina rugula is a major component of the encrusting fauna of physically disturbed shallow water habitats in Antarctica. On rocks collected from Rothera Point, Adelaide Island, F. […]
The Antarctic Ice Sheet is today an important part of the global climate engine, and probably has been so for most of its long existence. However, the details of its […]
The Antarctic Ice Sheet is a key feature of the global climate engine today, and has been so for most of its 35 Myr or longer history. It influences global […]
The Antarctic cryosphere has had a major effect on Cenozoic global climates, sea levels, oceanography, and Southern Hemisphere biota. Yet the climatic history of Antarctica and its contribution to global […]
A new numerical model of the high latitude ionosphere is used in conjunction with data from the EISCAT radar facility to study the formation and structure of polar patches. Inputs […]
Band-limited Pc-3 pulsations were observed on one day with pulsation magnetometers, photometers and in VLF activity at South Pole and simultaneously, electric field pulsations were observed in the ionospheric cusp […]
Twelve epipelagic copepod species were reviewed to compare their adaptations to the short primary production season and low temperatures which characterise the Southern Ocean. The species show a spectrum of […]
Longlining operations for Dissostichus eleginoides off South Georgia were assessed for interactions with seabirds and the effectiveness of measures employed by CCAMLR to mitigate seabird mortality. Following an agreement between […]
