The arrival of Antarctic fur seals at a breeding beach on Bird Island, South Georgia, was studied over five consecutive breeding seasons, 1983 to 1987. Experienced bulls arrived first and […]
Field‐aligned currents (FACs), also known as Birkeland currents, are the agents by which energy and momentum are transferred to the ionosphere from the magnetosphere and solar wind. This coupling is […]
Van Allen Probes observations are used to statistically investigate plasmaspheric hiss wave properties. This analysis shows that the wave normal direction of plasmaspheric hiss is predominantly field aligned at larger […]
The implicit assumption of many ecological studies is that animal behaviour and resource use are geographically uniform. However, central place foraging species often have geographically isolated breeding colonies that are […]
The shell material of marine benthic bivalves provides a sensitive archive of water chemistry immediately above the sediment–water interface, which in turn is affected by sedimentary geochemistry and redox reactions. […]
The South Sandwich Islands are a relatively pristine volcanic archipelago in the Southern Ocean that experience high levels of natural disturbance. The archipelago spans the biological transition between the sub-Antarctic […]
We present a global model of plasmaspheric hiss, using data from eight satellites, extending the coverage and improving the statistics of existing models. We use geomagnetic activity dependent templates to […]
Antarctica and surrounding waters are often considered pristine, but may be subject to local pollution from tourism, fishing and governmental research programme activities. In particular, the quantification of microplastic pollution […]
Year‐round variability in the Ross Gyre (RG), Antarctica, during 2011‐2015, is derived using radar altimetry. The RG is characterized by a bounded recirculating component, and a westward ‘throughflow’ to the […]
We present two narratives on the future of Antarctica and the Southern Ocean, from the perspective of an observer looking back from 2070. In the first scenario, greenhouse gas emissions […]
Morphologies of animals can vary significantly, and variation in characters in relation to taxonomic discrimination is often either underestimated or not evaluated. It can, however, make the identification and separation […]
