The eastward-flowing Antarctic Circumpolar Current (ACC) has influenced sedimentation on the slope and floor of the western Falkland Trough, where the axis of the current is topographically constrained. Deep-water flow […]
We investigate the absorption of electromagnetic ion cyclotron (EMIC) wave energy by He+ in the outer magnetosphere and the subsequent perpendicular-heating of He+. Plasma models, based on satellite data, are […]
Linearizations about two horizontal-dimensional ice sheets are proposed as methods of generating normal mode initializations for ice-sheet models and for computing the short-term response. Linearized models can be generated directly […]
A linearized perturbation about the Vialov-Nye fixed-span solution for a steady-state ice sheet yields a Sturm-Liouville problem. The numerical eigenvalue problem is solved and the resulting normal modes are used […]
Small scale field and laboratory observations of sub-glacial sediment deformation suggest that failure is the predominant method of sediment deformation, while large scale modelling studies using a viscous model of […]
Morphological descriptions of the seeds of eight phanerogamic species are provided together with observations on the dispersal of the seeds and the habitats of parent plants. These are discussed in […]
Seeds of six endemic species and two circumpolar species were collected from several sites on Kerguelen and tested for germination between 5 and 25°C on thermogradient bars. Pringlea antiscorbutica and […]
Upper Jurassic-Lower Cretaceous rocks of the Byers Group, exposed on Byers Peninsula, Livingston Island, record the expansion of Gondwana-margin continental-arc facies into a marine intra-arc basin. At least 1.3 km […]
An analysis of a long-term surface air temperature record for Fossil Bluff in the George VI Sound, West Antarctic Peninsula (WAP) documents in detail some important aspects of the climate […]
An explanation is sought for the marked variation in maximum sea ice extent observed between 2 years in the 2 areas of greatest interannual variability in winter ice extent in […]
