Surface radiation measurements and other climatological data were used to validate the representation of the surface energy balance over the East Antarctic Ice Sheet in the U.K. Meteorological Office Unified […]
Well-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 […]
The 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 […]
Seismic 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 […]
Magnetic, 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 […]
Satellite 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 […]
Ground-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 […]
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 […]
