Sediment-water fluxes of nutrients in an Antarctic coastal environment: influence of bioturbation
Read more of: Sediment-water fluxes of nutrients in an Antarctic coastal environment: influence of bioturbationRates of exchanges of nitrate and ammonium across the sediment-water interface were measured in an inshore marine environment at Signy Island, South Orkney Islands, Antarctica, over 6 months from August […]

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 […]

Early Palaeozoic rather than Neoproterozoic volcanism and rifting within the Transantarctic Mountains
Read more of: Early Palaeozoic rather than Neoproterozoic volcanism and rifting within the Transantarctic MountainsNew U-Pb dating of zircons separated from felsic volcanic rocks of the Patuxent and Gambacorta formations from the Pensacola Mountains in the Transantarctic Mountains, Antarctica, yields earliest Ordovician ages of […]

Tardigrades from Signy Island, South Orkney Islands, with particular reference to freshwater species
Read more of: Tardigrades from Signy Island, South Orkney Islands, with particular reference to freshwater speciesSeventeen species of Tardigrada from lakes and catchments on Signy Island, South Orkney Islands, are described. Two species, Echiniscus punctus and Isohypsibius laevis are new to science, and two, Oreella […]
