1. A model computation of the temporal changes of surface gravity and geoidal signal induced by the evolving Greenland ice sheet

   This paper deals with present-day gravity changes in response to the evolving Greenland ice sheet. We present a detailed computation from a 3-D thermomechanical ice sheet model that is interactively […]

2. Coupled marine-ice-sheet/Earth dynamics using a dynamically consistent ice-sheet model and a self-gravitating viscous Earth model

   We use a self-gravitating viscoelastic model of the Earth and a dynamically consistent marine ice-sheet model to study the relationships between marine ice-sheet dynamics, relative sea level, basal topography and […]

3. Effects of a viscoelastic lithosphere on the isostatic bedrock response

   The lithosphere responds to loading by elastic flexure which is followed by viscous relaxation, the amount of which depends on the stress duration. This study compares results of an Earth […]

4. Life on the edge: the plankton and chemistry of Beaver Lake, an ultra-oligotrophic epishelf lake, Antarctica

   1. Beaver Lake, a large epishelf lake in eastern Antarctica was sampled on two occasions during the austral summer of 2000. Two sites, one 1 km offshore and another 6 […]

5. Initial comparisons of planetary waves in the stratosphere, mesosphere and ionosphere over Antarctica

   Planetary wave signatures, with periods of approximately 16, 10 and 5 days have been observed at altitudes ranging from 30 km to 220 km over Halley (76°S, 26°W), Antarctica. A […]

6. Molluscan stable isotope temperature estimates of the southwestern Ross Sea during the Early Oligocene and Early Miocene, CRP-2/2A and CRP-3, Victoria Land basin, Antarctica

   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 […]

7. Strontium isotope stratigraphy for CRP-3, Victoria Land Basin, Antarctica

   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) […]

8. Cenozoic tectonic history, seismicity and palaeoseismicity of the Antarctic Peninsula Pacific margin

   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 […]

9. Deriving palaeomagnetic poles from independently assessed inclination and declination data: implications for South American poles since 120 Ma

   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 […]

10. A case study test of Araki’s physical model of geomagnetic sudden commencement

    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 […]

11. Discovery of a recurrent lava lake on Saunders Island (South Sandwich Islands) using AVHRR imagery

    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). […]

12. Observations of cloud and precipitation particles on the Avery Plateau, Antarctic Peninsula

    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 […]
