1. Lateral meltwater transfer across an Antarctic ice shelf.

   Surface meltwater on ice shelves can exist as slush, it can pond in lakes or crevasses, or it can flow in surface streams and rivers. The collapse of the Larsen […]

2. Control of the oceanic heat content of the Getz‐Dotson Trough, Antarctica, by the Amundsen Sea Low

   The changing supply of warm Circumpolar Deep Water (CDW) to the West Antarctic continental shelf is responsible for the basal melting and thinning of the West Antarctic ice shelves that […]

3. The evaluation of the North Atlantic climate system in UKESM1 historical simulations for CMIP6

   Earth System models enable a broad range of climate interactions that physical climate models are unable to simulate. However, the extent to which adding Earth System components changes or improves […]

4. Interhemispheric comparisons of large nighttime magnetic perturbation events relevant to GICs

   Nearly all studies of impulsive magnetic perturbation events (MPEs) with large magnetic field variability (dB/dt) that can produce dangerous geomagnetically‐induced currents (GICs) have used data from the northern hemisphere. Here […]

5. Multiscale observation of two polar cap arcs occurring on different magnetic field topologies

   This paper presents observations of polar cap arc substructure down to scale sizes of meters and temporal resolution of milliseconds. Two case studies containing polar cap arcs occurring over Svalbard […]

6. Deglaciation of Pope Glacier implies widespread early Holocene ice sheet thinning in the Amundsen Sea sector of Antarctica.

   The Amundsen Sea sector of the Antarctic ice sheet presently dominates the contribution from Antarctica to sea level rise. Several large ice streams that currently drain the sector have experienced […]

7. Morphometry of bedrock meltwater channels on Antarctic inner continental shelves

   Expanding multibeam bathymetric data coverage over the last two decades has revealed extensive networks of submarine channels incised into bedrock on the Antarctic inner continental shelf. The large dimensions and […]

8. Multiple colonization and dispersal events hide the early origin and induce a lack of genetic structure of the moss Bryum argenteum in Antarctica.

   The dispersal routes of taxa with transoceanic disjunctions remain poorly understood, with the potential roles of Antarctica not yet demonstrated. Mosses are suitable organisms to test direct intra‐Antarctic dispersal, as […]

9. The impact of temperature and crystal orientation fabric on the dynamics of mountain glaciers and ice streams

   Streaming ice accounts for a major fraction of global ice flux, yet we cannot yet fully explain the dominant controls on its kinematics. In this contribution, we use an anisotropic […]

10. Sea-ice-free Arctic during the Last Interglacial supports fast future loss

    The Last Interglacial (LIG), a warmer period 130,000–116,000 years before present, is a potential analogue for future climate change. Stronger LIG summertime insolation at high northern latitudes drove Arctic land […]

11. RABID: Basal conditions on Rutford Ice Stream, West Antarctica: Hot-water drilling and downhole instrumentation. British Antarctic Survey Field Report, R/2004/S3 [BAS Archives Ref: AD6/2R/2004/S3]

    The main fieldwork for project AFI 1-05 (the RABID project) was carried out on Rutford Ice Stream in the 2004/05 field season. The biggest scientific task was to access the […]

12. Triassic magmatism and metamorphism in the Antarctic Peninsula: identifying the extent and timing of the Gondwanide Orogeny

    The mid- to Late Triassic marks an episode of magmatism, deformation and metamorphism along the proto-Pacific margin of the Antarctic Peninsula and Patagonia. Calc-alkaline magmatism at ∼227 Ma developed in a […]
