Stable isotope analyses of marine bivalve growth increment samples have been used to estimate early Oligocene (29.4 – 31.2) Ma and early Miocene (24.0 Ma) seafloor palaeotemperatures from the southwestern […]
Strontium isotope stratigraphy was used to date 5 discrete horizons within the CRP-3 drillhole. A single in situ modiolid bivalve fragment at 10.88 mbsf gives an age of 30.9 (±0.8) […]
Global earthquake catalogues do not record any earthquakes south of Bransfield Strait beneath the Antarctic Peninsula or its flanking continental shelves. Such low seismicity is consistent with neotectonic interpretations which […]
Palaeomagnetic poles for a stable continental block are typically defined from a combination of declination and inclination information from several temporally constrained studies. Poles from regions that have undergone vertical-axis […]
This paper tests the Araki [1994] computational model of the Earth-ionosphere system during geomagnetic sudden commencement (sc). In particular, we test the model’s ability to predict the signs of the […]
Monitoring of the remote SouthSandwichIslands volcanic arc, using advanced very high resolution radiometer (AVHRR) data, has identified a radiant pixel on channels 3 (3.55–3.93 μm) and (rarely) 4 (10.3–11.3 μm). […]
Surface-based observations were taken of cloud and precipitation particles on the Avery Plateau (66°50.34′S 65°29.58′W), Antarctic Peninsula from 25 November to 13 December 1995. This paper considers cloud parameters on […]
The pattern of inter‐annual variability in the atmospheric circulation around Antarctica has a maximum over the Amundsen‐Bellinghausen Sea (ABS), which is particularly strong during the winter (June, July and August). […]
The Hadley Centre climate model version HadAM2 is used to study the sensitivity of modelled Antarctic climate to the parametrization of surface and boundary-layer heat fluxes under stable conditions. Specifically, […]
The first Carboniferous and ?Permian marine macrofaunas from the Antarctic continent are described from three sites near Mount King, Alexander Island, Antarctic Peninsula. They include bivalves, brachiopods, bryozoans, crinoids, gastropods, […]
Analysis of the Batoka Basalts exposed in the Zambezi Gorge some 40 km east of Victoria Falls characterizes them as high Fe, moderately high Ti, and low K, P, and […]
Upper boundary conditions for numerical models of the ocean are conventionally formulated under the premise that the boundary is a material surface. In the presence of an ice cover, such […]
