New seismic data support Cenozoic rifting in George VI Sound, Antarctic Peninsula
Read more of: New seismic data support Cenozoic rifting in George VI Sound, Antarctic PeninsulaNew 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 […]

Seasonality of polypide recycling and sexual reproduction in some erect Antarctic bryozoans
Read more of: Seasonality of polypide recycling and sexual reproduction in some erect Antarctic bryozoansThe 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 ecology of an assemblage dominant: the encrusting bryozoan Fenestrulina rugula
Read more of: The ecology of an assemblage dominant: the encrusting bryozoan Fenestrulina rugulaThe 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. […]

Ice sheet history from Antarctic continental margin Sediments: the ANTOSTRAT approach
Read more of: Ice sheet history from Antarctic continental margin Sediments: the ANTOSTRAT approachThe 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 […]

Modelling studies of the effects of cusp inputs on the polar ionosphere
Read more of: Modelling studies of the effects of cusp inputs on the polar ionosphereA 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 […]

The coherence scale length of band-limited Pc3 pulsations in the ionosphere
Read more of: The coherence scale length of band-limited Pc3 pulsations in the ionosphereBand-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 […]

Life cycle strategies of epipelagic copepods in the Southern Ocean
Read more of: Life cycle strategies of epipelagic copepods in the Southern OceanTwelve 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 […]
