Glaciological and oceanographic evidence of high melt rates beneath Pine Island Glacier, West Antarctica
Read more of: Glaciological and oceanographic evidence of high melt rates beneath Pine Island Glacier, West AntarcticaSatellite imagery indicates that the floating terminus of Pine Island Glacier has changed little in extent over the past two decades. Data on the velocity and thickness of the glacier […]

Dynasonde observations of Pc1 propagation in the ionosphere
Read more of: Dynasonde observations of Pc1 propagation in the ionosphereGround-based observations of Pc1 geomagnetic pulsations propagating in the ionosphere over Halley (76 °S, 27 °W, L ~ 4.2), Antarctica, have been made. The direction of propagation of the Pc1 […]

Latitudinal variation of quasi-biennial oscillation modulation of the semidiurnal tide in the lower thermosphere
Read more of: Latitudinal variation of quasi-biennial oscillation modulation of the semidiurnal tide in the lower thermospherePerturbations 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 […]

Milk fatty acid signatures indicate both major and minor shifts in the diet of lactating Antarctic fur seals
Read more of: Milk fatty acid signatures indicate both major and minor shifts in the diet of lactating Antarctic fur sealsFatty 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 […]

Diving behaviour of the grey-headed albatross
Read more of: Diving behaviour of the grey-headed albatrossForaging 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, […]

Pliocene-Holocene contourite deposition under the Antarctic Circumpolar Current, western Falkland Trough, south Atlantic Ocean
Read more of: Pliocene-Holocene contourite deposition under the Antarctic Circumpolar Current, western Falkland Trough, south Atlantic OceanThe 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 […]

Wave heating of He+by electromagnetic ion cyclotron waves in the magnetosphere: Heating near the H+-He+bi-ion resonance frequency
Read more of: Wave heating of He+by electromagnetic ion cyclotron waves in the magnetosphere: Heating near the H+-He+bi-ion resonance frequencyWe 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 […]

Use of ice-sheet normal modes for initialization and modelling small changes
Read more of: Use of ice-sheet normal modes for initialization and modelling small changesLinearizations 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 […]

Normal modes of an ice sheet
Read more of: Normal modes of an ice sheetA 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 […]
