Within the global context, Antarctica has a key role to play in understanding long-term change in the upper atmosphere, both because of its isolation from the rest of the world […]
In the mesosphere and lower thermosphere the contrasts between the Antarctic and Arctic regarding both the energy inputs and the consequent dynamics, energetics and chemistry mean that comparative polar observations […]
In 1997 a 121 m ice core was retrieved from Lomonosovfonna, the highest ice field in Spitsbergen, Svalbard (1250 m a.s.l.). Radar measurements indicate an ice depth of 126.5 m, […]
A psychrophilic, aerobic bacterium designated A2iT was isolated from marine sediment recovered from shallow waters surrounding Adelaide Island, Antarctica (67S 34H S, 68S 07H W). The organism exhibited xylanolytic and […]
Reproductive pentoxylalean material from the Albian Triton Point Formation, Fossil Bluff Group of Alexander Island, Antarctica is the youngest record of this group globally. Leaves are referred to Taeniopteris daintreei […]
The roots of a British Antarctic policy can be traced, paradoxically, back to the establishment of a meteorological station by the Scottish Antarctic Expedition in the South Orkneys, in 1903, […]
We present anewsimulationcode for electrostatic waves in one dimension which uses the Vlasovequation to integrate the distribution function and Ampère’sequation to integrate the electric field forward in time. Previous Vlasovcodes […]
Much of the Antarctic coastline comprises large, floating ice shelves, beneath which waters from the open ocean circulate. The interaction of the seawater with the base of these ice shelves […]
The Rauer Islands contain more than fifty shallow lakes and small ephemeral ponds. Despite their proximity to the Vestfold fills – one of the most diverse and intensively studied lake […]
Lake sediments in the Larsemann Hills contain a great diversity ofbiological and physical markers from which past environments can be inferred. In order to determine the timing of environmental changes […]
