1. Taxonomic studies of Achnanthes(Bacillariophyta) in freshwater maritime antarctic lakes

   Eleven species of Achnanthes from Signy Island, South Orkney Islands are described including one new species. Benthic algal material from a range of shallow lakes of varying trophic status was […]

3. Sediment-water fluxes of nutrients in an Antarctic coastal environment: influence of bioturbation

   Rates 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 […]

4. A biological acoustic survey in the marginal ice-edge zone of the Bellingshausen Sea

   An acoustic survey at 38 kHz was carried out from R.R.S. Discovery in the Bellingshausen Sea from 23 November to 7 December 1992 as part of the U.K. Joint Global […]

5. Temporal variation in Antarctic sea-ice: analysis of a long term fast-ice record from the South Orkney Islands

   Detection 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 […]

6. Spatial structure of the Southern Ocean ecosystem: predator-prey linkages in Southern Ocean food webs

   1. 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 […]

7. Radar observations of auroral zone flows during a multiple-onset substorm

   We 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 […]

8. The role of upstream ULF waves in the generation of quasi-periodic ELF-VLF emissions

   Recent 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 […]

9. 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 […]

11. Early Palaeozoic rather than Neoproterozoic volcanism and rifting within the Transantarctic Mountains

    New 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 […]

12. Tardigrades from Signy Island, South Orkney Islands, with particular reference to freshwater species

    Seventeen 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 […]
