1. Growth in the bivalve Yoldia eightsi at Signy Island, Antarctica, determined from internal shell increments and calcium-45 incorporation

   The growth rate of the infaunal nuculanid bivalve Yoldia eightsi at Factory Cove, Signy Island, South Orkney Islands (maritime Antarctica), was estimated from internal shell increments and 45Ca incorporation of […]

2. Extending the Antarctic meteorological record using ice-sheet temperature profiles

   Two vertical ice temperature profiles from locations in the Antarctic Peninsula unaffected by meltwater are presented. A simple time-dependent heat diffusion-advection model is used to infer broad surface temperature variations […]

3. Temperature and salinity beneath Ronne Ice Shelf, Antarctica

   Salinity and temperature measurements have been made beneath Ronne Ice Shelf, Antarctica. Access to the seawater was gained by hot-water drilling through 562 m of ice at a site 300 […]

4. Annual survival of Sparrowhawks Accipiter nisus breeding in three areas of Britain

   Annual survival of breeding female Sparrowhawks Accipiter nisus was estimated by a capture-recapture procedure in three different areas, Eskdale and Annandale in southern Scotland and Rockingham Forest in east-central England. […]

5. Measurements of seasonal rates and annual budgets of organic carbon fluxes in an Antarctic coastal environment at Signy Island, South Orkney Islands, suggest a broader balance between production and decomposition

   We report here the first comprehensive seasonal study of benthic microbial activity in an Antarctic coastal environment. Measurements were made from December 1990 to February 1992 of oxygen uptake and […]

8. The fractionation of sea salt and acids during transport across an Antarctic ice shelf

   Analyses of Cl−, NO3−, SO42−, Na and Mg made on a series of surface snow samples, collected at 4 km intervals along a 116 km traverse of the Fimbul Ice […]

9. Evidence for winter/spring denitrification of the stratosphere in the nitrate record of Antarctic firn cores

   A firn core from within the polar vortex in the Weddell Sea sector of Antarctica shows nitrate peaks that occur in the spring or early summer. They are far less […]

10. Plasma flow bursts in the nightside auroral zone ionosphere and their relation to geomagnetic activity

    We examine the nature of flows in the nightside auroral zone ionosphere and their relationship with concurrent geomagnetic activity by studying a three-hour interval of ground-based radar, magnetometer array and […]

11. Dielectric properties of frozen clay and silt soils

    The dielectric properties of a clay and a silt soil have been studied at low water saturations at temperatures between −100°C and −15°C. The frequency range of the study (20 […]

12. Dielectric properties of ice containing acid and salt impurity at microwave and low frequencies

    We compare the microwave and low-frequency (LF) dielectric conductivity of natural and artificial ice as a function of impurity concentration and temperature. We find a linear dependence of conductivity on […]
