The annual and longitudinal variations in plasmaspheric ion density
This paper shows that at solar maximum, equatorial ion densities at L = 2.5 are substantially higher at American longitudes in the December months than in the June months. This […]

Ecological drivers of change at South Georgia: the krill surplus, or climate variability
Read more of: Ecological drivers of change at South Georgia: the krill surplus, or climate variabilityMacaroni penguins Eudyptes chrysolophus are thought to be one of the most important mesopredators in the Southern Ocean having a greater impact on prey availability and abundance than any other […]

Antarctic krill under sea ice: elevated abundance in a narrow band just south of ice edge
Read more of: Antarctic krill under sea ice: elevated abundance in a narrow band just south of ice edgeWe surveyed Antarctic krill (Euphausia superba) under sea ice using the autonomous underwater vehicle Autosub-2. Krill were concentrated within a band under ice between 1 and 13 kilometers south of […]

An analysis of the oxidation potential of the South Pole boundary layer and the influence of stratospheric ozone depletion
Read more of: An analysis of the oxidation potential of the South Pole boundary layer and the influence of stratospheric ozone depletionThe summertime atmospheric boundary layer over the South Pole has recently been shown to be highly oxidizing, with greater concentrations of NO and OH than previously expected. The source of […]

Microgeographic genetic variation of populations of Idotea chelipes (Crustacea: Isopoda) in lagoons of the southern English coast
Read more of: Microgeographic genetic variation of populations of Idotea chelipes (Crustacea: Isopoda) in lagoons of the southern English coastAllozyme variability was examined using starch-gel electrophoresis between sub-populations of Idotea chelipes over a small geographic distance (approx. 104 km), in lagoons within the Solent area (Fort Gilkicker Moat; Ashlett […]

Reduction in muscle fibre number during the adaptive radiation of notothenioid fishes: a phylogenetic perspective
Read more of: Reduction in muscle fibre number during the adaptive radiation of notothenioid fishes: a phylogenetic perspectiveThe fish fauna of the continental shelf of the Southern Ocean is dominated by a single sub-order of Perciformes, the Notothenioidei, which have unusually large diameter skeletal muscle fibres. We […]

Utilizing riometry to observe gravity waves in the sunlit mesosphere
Read more of: Utilizing riometry to observe gravity waves in the sunlit mesosphereThe novel use of imaging riometers to observe mesospheric gravity waves is described. Imaging riometers respond to changes in the absorption of cosmic radio noise in the ionospheric D-region which […]
