Validity of the temperature reconstruction from water isotopes in ice cores
Read more of: Validity of the temperature reconstruction from water isotopes in ice coresWell-documented present-day distributions of stable water isotopes (HDO and H218O) show the existence, in middle and high latitudes, of a linear relationship between the mean annual isotope content of precipitation […]

First mesospheric observations using an imaging Doppler interferometer adaptation of the dynasonde at Halley, Antarctica
Read more of: First mesospheric observations using an imaging Doppler interferometer adaptation of the dynasonde at Halley, AntarcticaThe digital ionospheric sounder, or dynasonde, located at the British Antarctic Survey’s research station at Halley, Antarctica, has recently been operated as an imaging Doppler interferometer (IDI). The implementation of […]

Seabed topography under the southern and western Ronne Ice Shelf, derived from seismic surveys
Read more of: Seabed topography under the southern and western Ronne Ice Shelf, derived from seismic surveysSeismic reflection measurements of ice thickness and water-column thickness have been made over the southern and western Ronne Ice Shelf, from which, the seabed elevation has been determined. A 2300 […]

Cenozoic tectonic evolution of the Marguerite Bay area, Antarctic Peninsula, interpreted from geophysical data
Read more of: Cenozoic tectonic evolution of the Marguerite Bay area, Antarctic Peninsula, interpreted from geophysical dataMagnetic, gravity and bathymetric data from Marguerite Bay are used to study the relationships between oceanic and continental tectonic evolution in the arc and fore-arc of the Antarctic Peninsula. The […]

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, […]
