2. Thin-film flows with wall slip: an asymptotic analysis of higher order glacier flow models

   Free-surface thin-film flows can principally be described by two types of models. Lubrication models assume that shear stresses are dominant in the force balance of the flow and are appropriate […]

3. How do polar marine ecosystems respond to rapid climate change?

   Climate change will alter marine ecosystems; however, the complexity of the food webs, combined with chronic undersampling, constrains efforts to predict their future and to optimally manage and protect marine […]

4. Use of POES SEM-2 observations to examine radiation belt dynamics and energetic electron precipitation into the atmosphere

   The coupling of the Van Allen radiation belts to the Earth’s atmosphere through precipitating particles is an area of intense scientific interest. Currently, there are significant uncertainties surrounding the precipitating […]

5. Establishing lichenometric ages for nineteenth- and twentieth-century glacier fluctuations on South Georgia (South Atlantic)

   Glaciers in small mountain cirques on South Georgia respond rapidly and sensitively to changes in South Atlantic climate. The timing and rate of their deglaciation can be used to examine […]

6. Middle Jurassic rhyolite volcanism of eastern Graham Land, Antarctic Peninsula: age correlations and stratigraphic relationships

   Silicic volcanism at c. 168 Ma has been identified previously on the Antarctic Peninsula, and the Mapple Formation, which includes those volcanic rocks, has been defined and documented from one […]

7. Evidence for elevated alkalinity in the glacial Southern Ocean

   An increase in whole ocean alkalinity during glacial periods could account, in part, for the drawdown of atmospheric CO2 into the ocean. Such an increase was inevitable due to the […]

8. Krill population dynamics at South Georgia: implications for ecosystem-based fisheries management

   The South Georgia region supports a large biomass of krill that is subject to high inter-annual variability. The apparent lack of a locally self-maintaining krill population at South Georgia means […]

9. Estimating basal properties of ice streams from surface measurements: a non-linear Bayesian inverse approach applied to synthetic data

   We propose a new approach to indirectly estimate basal properties of ice streams, i.e. bedrock topography and basal slipperiness, from observations of surface topography and surface velocities. We demonstrate how […]

10. The eradication of feral cats from Ascension Island and its subsequent recolonization by seabirds

    The introduction of mammal predators to islands often results in rapid declines in the number and range of seabirds. On Ascension Island the introduction of cats in 1815 resulted in […]

11. Deep-sea demersal fish species richness in the Porcupine Seabight, NE Atlantic Ocean: global and regional patterns

    The ichthyofauna of ocean margin regions is characterised by a succession of different species occurring at different depths. This study was aimed at determining whether the resultant pattern of species […]

12. Ingestion of fishing gear and entanglements of seabirds: monitoring and implications for management

    Fisheries are increasingly adopting ecosystem approaches to better manage impacts on non-target species. Although deliberate dumping of plastics at sea is banned, not all fisheries legislation prohibits discarding of gear […]
