The goals of ecosystem based management (EBM) are strategically ambiguous, meaning that they require interpretation to identify objectives for ecosystem state. Ecosystem states that are useful for achieving such objectives […]
Understanding the relationship between life-history variation and population structure in marine invertebrates is not straightforward. This is particularly true of polar species due to the difficulty of obtaining samples and […]
The gravity wave field in the lower stratosphere (between 15 km and 22 km altitude) above Mount Pleasant Airport (51°49’S, 58°26’W), on the Falkland Islands is studied using over 2100 high-resolution radiosonde […]
We combined an ensemble of satellite altimetry, interferometry, and gravimetry data sets using common geographical regions, time intervals, and models of surface mass balance and glacial isostatic adjustment to estimate […]
The Super Dual Auroral Radar Network (SuperDARN) is a network of HF radars used to study phenomena in the Earth’s magnetosphere, ionosphere, and upper atmosphere. Phenomena in the upper mesosphere […]
The high latitudes inhabited by Antarctic krill Euphausia superba Dana are characterised by extreme changes in seasonal conditions, with very low food availability, long periods of darkness and a massive […]
Migratory divides are contact zones between breeding populations that use divergent migratory routes and have been described in a variety of species. These divides are of major importance to evolution, […]
Recent studies suggested that, during the transition out of the last glacial period, one near‐coastal site in Antarctica showed a response similar to that of Greenland, and unlike that of […]
Data are presented here on low molecular weight carbohydrates contents (assessed from samples collected in situ) of selected, representative terrestrial species from the maritime Antarctic. Significant seasonal variation for most […]
The Bouvet triple junction has been proposed to have evolved as a ridge-fault-fault (RFF) type between 20 and 10 Ma, connecting the southernmost Mid-Atlantic Ridge (SMAR) with the Bouvet and […]
The current status of birds at Rothera, Adelaide Land, Antarctica is presented. Of the 23 species recorded, Snow Petrel Pagodroma nivea, Wilson’s Storm Petrel Oceanites oceanicus, Antarctic Shag or Cormorant […]
