Tide-induced lateral movement of Brunt Ice Shelf, Antarctica
[1] Accurate position data show that Brunt Ice Shelf has an irregular three-dimensional motion driven by the ocean tide. A 30-day GPS record from Halley station shows not only the […]

Polarization of radio waves transmitted through Antarctic ice shelves
Read more of: Polarization of radio waves transmitted through Antarctic ice shelvesThe polarization behaviour of radar waves transmitted through two Antarctic ice shelves has been investigated using a step frequency radar with a centre frequency of 300 MHz and a bandwidth […]

He+ dominance in the plasmasphere during geomagnetically disturbed periods: 1. Observational results
Read more of: He+ dominance in the plasmasphere during geomagnetically disturbed periods: 1. Observational resultsObservations made by the DMSP 1710 satellite during the recovery phase from geomagnetic disturbances in June 1991 show regions of He+ dominance around 830 km altitude at 09:00 MLT. These […]

Palaeozoic to Mesozoic polyphase deformation of the Patuxent Range, Pensacola Mountains, Antarctica
Read more of: Palaeozoic to Mesozoic polyphase deformation of the Patuxent Range, Pensacola Mountains, AntarcticaThe Patuxent Range forms the most southerly third of the Pensacola Mountains, East Antarctica. Largely unstudied since the original geological survey work of the 1960s, the Patuxent Range was thought […]

Tectonic evolution of the Pacific margin of Antarctica 2. Structure of Late Cretaceous-early Tertiary plate boundaries in the Bellingshausen Sea from seismic reflection and gravity data
Read more of: Tectonic evolution of the Pacific margin of Antarctica 2. Structure of Late Cretaceous-early Tertiary plate boundaries in the Bellingshausen Sea from seismic reflection and gravity dataInterpretations of multichannel seismic (MCS) reflection and potential field data suggest that some prominent gravity anomalies in the Bellingshausen Sea are associated with plate boundaries that were active during the […]

The importance of the Patagonian Shelf for top predator species breeding at South Georgia
Read more of: The importance of the Patagonian Shelf for top predator species breeding at South Georgia1. The rich zooplankton, fish and squid resources on the Patagonian Shelf sustain substantial populations of largely resident seabirds and marine mammals, These habitats are also visited seasonally by similar […]
