1. Influence of channelling on heating in ice-sheet flows

   Ice‐sheet flows can be channelled by perturbations in the basal topography or in the sliding coefficient. These lead to spatial variation in the steady profile, the flux and the dissipative […]

2. Migration routes and strategies in a highly aerial migrant, the Common Swift Apus apus, revealed by light-level geolocators

   The tracking of small avian migrants has only recently become possible by the use of small light-level geolocators, allowing the reconstruction of whole migration routes, as well as timing and […]

3. Influence of temperature on the hygropreference of the collembolan, Cryptopygus antarcticus, and the mite, Alaskozetes antarcticus from the maritime Antarctic

   The hygropreference of adult Cryptopygusantarcticus and Alaskozetesantarcticus was investigated over 2 h at 5, 10 and 20°C, along humidity gradients (9–98% RH) established by means of different salt solutions. Two […]

4. Biologging, remotely-sensed oceanography and the continuous plankton recorder reveal the environmental determinants of a seabird wintering hotspot

   Marine environments are greatly affected by climate change, and understanding how this perturbation affects marine vertebrates is a major issue. In this context, it is essential to identify the environmental […]

5. Stratigraphy and age of the Lower Cretaceous Pedersen Formation, northern Antarctic Peninsula

   The Pedersen Formation includes conglomerate-dominated successions exposed on Pedersen Nunatak (142 m thick) and southern Sobral Peninsula (750–1000 m thick). As re-defined here, it also includes mudstone and sandstone in […]

6. Sims Island: first data from a Pliocene alkaline volcanic centre in eastern Ellsworth Land

   Although Sims Island (73°17′S/78°33′W), a bedrock peak in Carroll Inlet on the English Coast of eastern Ellsworth Land (Fig. 1), had previously been observed and photographed from the air (e.g. […]

7. Inter-colony differences in the incubation pattern of streaked shearwaters in relation to the local marine environment

   Foraging trip duratiom of breeding seabirds is affected by characteristics of available feeding habitat in the marine environment, which may in turn, generate inter-colony difference in the patterns of nest […]

8. Magnetic properties of Upper Quaternary sediments from the Scotia Sea, Antarctica

   Magnetic properties of bulk sediment samples taken from three cores from the Scotia Sea, Antarctica were determined using a fully-automated variable field translation balance. Fine-grained detrital magnetite is identified as […]

9. Contrasting foraging strategies of gannets Morus bassanus at two North Atlantic colonies: foraging trip duration and foraging area fidelity

   Seabirds may be able to increase their foraging efficiency by learning the whereabouts of predictable sources of prey and returning repeatedly to these locations. The occurrence of such foraging area […]

11. Autonomous underwater vehicle exploration of the ocean cavity beneath an Antarctic ice shelf

    In recent years, mass loss from the Antarctic Ice Sheet has contributed nearly 0.5 mm yr–1 to global mean sea level rise, about one-sixth of the current rate (Church et […]

12. The Southern Ocean Observing System

    The Southern Ocean includes the only latitude band where the ocean circles the earth unobstructed by continental boundaries. This accident of geography has profound consequences for global ocean circulation, biogeochemical […]
