In this paper we review some recent work investigating the turbulent structure of the ionospheric plasma velocity in the polar and auroral regions. The studies make use of spatially distributed […]
In this short communication we examine the relationship between the Southern Hemisphere Annular Mode (SAM) and Antarctic near-surface temperatures using data from Antarctic stations for 1957-2004. This near half-century period […]
Following the PPARC programmatic review announced in the spring of last year, with its gloomy outlook for solar–terrestrial physics, three young scientists in the field mobilized the junior members of […]
The Super Dual Auroral Radar Network (SuperDARN) has been operating as an international co-operative organisation for over 10 years. The network has now grown so that the fields of view […]
We obtained growth rates of the copepod Calanus finmarchicus at different locations across the North Atlantic between May 1998 and June 2004. Animals were incubated for 2–9 days and fed […]
The detailed test morphology of the type suite of Globigerinoides sacculifer (Brady) is illustrated for the first time since the species was identified in 1877. Fossil representatives of this species […]
The early ontogenetic stages of Paralomis spinosissima Birstein and Vinogradow, 1972, are described in detail and illustrated, with notes on morphological variability observed. Larval and early juvenile development was described […]
Mesozooplankton were sampled at shelf and oceanic stations close to South Georgia, South Atlantic during austral autumn 2004 with a Longhurst Hardy Plankton Recorder. Onshelf biomass ranged from 2.18 to […]
Recent studies have revealed a previously unanticipated level of biodiversity present in the Antarctic littoral. Here, we report research on the ecophysiological strategies adopted by intertidal species that permit them […]
At St Kilda, Outer Hebrides, a large colony of great skuas Stercorarius skua feed extensively on one of the largest colonies of Leach’s storm-petrels Oceanodroma leucorhoa in Europe, but little […]
Models of snow processes in areas of possible large-scale change need to be site independent and physically based. Here, the accumulation and ablation of the seasonal snow cover beneath a […]
We used satellite telemetry methods to study macaroni penguins at South Georgia to determine how they ranged from their colonies during the early part of their breeding season at a […]
