Perturbations in the geomagnetic field at the Earth’s surface can result from variations in the neutral wind field in the lower thermosphere through dynamo action in the interfused ionospheric E […]
Fatty acid signature analysis is based on the principle that unique arrays of fatty acids within groups of organisms can be transferred, largely unaltered, up the marine food chain and […]
Foraging grey-headed albatrosses spent 86% of the night but only 20% of the day sitting on the sea; most diving activity occurred during daylight. During the broad-guard period of nesting, […]
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 […]
