A pelagic bryozoan from Antarctica
Spherical or sub-spherical bryozoan colonies were collected from the surface waters of a coastal polynya in the southeastern Weddell Sea near Halley Station in February 1992. These are the first […]

Temporal variation in Antarctic sea-ice: analysis of a long term fast-ice record from the South Orkney Islands
Read more of: Temporal variation in Antarctic sea-ice: analysis of a long term fast-ice record from the South Orkney IslandsDetection of climate-induced change in marine ecosystems requires a knowledge of the underlying variability of the environment. This paper uses a range of datasets to investigate the interannual variability in […]

Spatial structure of the Southern Ocean ecosystem: predator-prey linkages in Southern Ocean food webs
Read more of: Spatial structure of the Southern Ocean ecosystem: predator-prey linkages in Southern Ocean food webs1. The food chain of the Southern Ocean has often been characterized as simple and homogeneous. However, the population processes of a key prey organism, krill Euphausia superba, operate over […]

Radar observations of auroral zone flows during a multiple-onset substorm
Read more of: Radar observations of auroral zone flows during a multiple-onset substormWe present an analysis of ground magnetic field, ionospheric flow, geosynchronous particle, and interplanetary data during a multiple-onset substorm on 12 April 1988. Our principal results concern the modulations of […]

The role of upstream ULF waves in the generation of quasi-periodic ELF-VLF emissions
Read more of: The role of upstream ULF waves in the generation of quasi-periodic ELF-VLF emissionsRecent work suggests that the quasi-periodic (QP) modulation ~10–50 s of naturally occurring ELF-VLF radio emissions (~0.5–5 kHz) is produced by the compressional action of Pc3 magnetic pulsations on the […]

The environmental tolerances and behavioural ecology of the sub-Antarctic beach-hopper “Orchestia” scutigerula Dana (Crustacea: Amphipoda) from Husvik, South Georgia
Read more of: The environmental tolerances and behavioural ecology of the sub-Antarctic beach-hopper “Orchestia” scutigerula Dana (Crustacea: Amphipoda) from Husvik, South Georgia“Orchestia” scutigerula Dana (Amphipoda: Talitridae) was found beneath supralittoral stones at Kanin Point, S. Georgia. Microhabitat temperatures recorded over 6 summer weeks varied widely (hourly, diurnally, weekly), especially under stones […]
