Marine systems have traditionally been thought of as “open” with few barriers to gene flow. In particular, many marine organisms in the Southern Ocean purportedly possess circumpolar distributions that have […]
Polar lows are intense, small-scale cyclones in the high latitudes. Typically, polar lows are initiated through baroclinic processes, but they sometimes evolve into a post-baroclinic mature stage where air-sea interaction […]
The Amundsen Sea is a key region of Antarctica where ocean, atmosphere, sea ice, and ice sheet interact. For much of Antarctica, the relatively warm water of the open Southern […]
1. Canonical correspondence analysis of a diatom and water chemistry dataset from fifty-nine maritime Antarctic lakes situated on Signy and Livingston Islands showed that nutrients and functions of nutrients (NH4+, […]
Radar echoes from the upper mesosphere recorded by the dynasonde at Halley (76°S, 27°W), Antarctica, over four years have been studied to reveal the diurnal and seasonal characteristics of echo […]
A SAOZ (System d’Analyse et d’Observations Zenithales) u.v.-visible spectrometer was installed at Faraday, Antarctica, in 1990, with a view to gaining year-round measurements of column ozone. Observations have been validated […]
IN 1985, Farman et al.1 announced that a dramatic reduction in total ozone was occurring in the atmosphere over Halley, Antarctica, during the polar spring. Analysis of satellite data revealed […]
Aeromagnetic anomaly data collected between 67°S and 70°S crossing the Antarctic Peninsula and adjacent offshore areas show a prominent NW-SE trend in the magnetic fabric. Apparent lateral offsets, previously recognized […]
The seawater that comes into contact with the base of a floating ice shelf is modified as a result of the phase changes that occur. Melting is prevalent in the […]
Plasma flow vectors have been derived from data recorded by the Advanced Ionospheric Sounder (operating as a Dynasonde) at Halley, Antarctica (76°, 27°W). Single bulk flow vectors derived from the […]
Seismic reflection surveys were carried out over the Larsen Ice Shelf to examine the extent of the observed sedimentary sequences of the Larsen Basin as suggested by aeromagnetic and gravity […]
