Mafic dykes (Groups A–D) intruded into Mesoproterozoic basement amphibolites, gneisses, and granitoids of the Cape Meredith Complex on the southern tip of West Falkland, provide an important record of at […]
We studied energy-provisioning rates and energy requirements of nestlings, as well as energy-expenditure rates of adults in Antarctic prions (Pachyptila desolata) on sub-Antarctic Bird Island, South Georgia. Special emphasis was […]
Magnetic profiles obtained during the Hesant 92/93 cruise with the R/V Hesperides show large amplitude anomalies (up to 1000 nT) along a 100 km wide band in the northern margin […]
Despite over thirty years of plate tectonic theory, the reasons why supercontinents like Gondwana disintegrate into smaller continents and disperse remain enigmatic. Current ideas mostly involve changes in plate-boundary driving […]
Sediment drifts are a major depositional product of bottom-current activity in deep-water settings, particularly on slopes and basin plains within, and adjacent to, continental margins. They commonly form positive features […]
Nine species of oribatid mites were represented in heat-extracted samples of soil and plant material and from pitfall trapping in the five main terrestrial plant communities on Heard Isl. Three […]
Identity, quantity and seasonal variation in recruiting invertebrate larvae were investigated at Signy Island, Antarctica. Nine settlement panels were deployed at each of three sites at depths ranging between five […]
Seismic reflection data from two lines on Rutford Ice Stream are presented and are compared with data already published from a third line on the ice stream. The amplitude and […]
A seismic reflection profile, perpendicular to the ice flow direction has been acquired on Rutford Ice Stream, Antarctica. An interpretation of both the amplitude and phase of the seismic reflections […]
