1. Analysis of a rapid sea ice retreat event in the Bellingshausen Sea

   The winter advance of the sea ice edge in the Bellingshausen Sea is frequently interrupted by periods of rapid retreat lasting a few days. The frequency and duration of such […]

2. Biogeochemical fluxes through microzooplankton

   [1] Microzooplankton ingest a significant fraction of primary production in the ocean and thus remineralize nutrients and stimulate regenerated primary production. We synthesized observations on microzooplankton carbon-specific grazing rate, partitioning […]

3. Poor acclimation capacities in Antarctic marine ectotherms

   Animals can respond to temperature change by the following means: using physiological flexibility (including acclimation); or adapting; or migrating, with acclimation proposed as the major mechanism dictating prospects for survival […]

4. Geographical variation in the behaviour of a central place forager: Antarctic fur seals foraging in contrasting environments

   Foragers show adaptive responses to changes within their environment, and such behavioural plasticity can be a significant driving force in speciation. We investigated how lactating Antarctic fur seals, Arctocephalus gazella, […]

5. Radiation belt electron precipitation due to geomagnetic storms: Significance to middle atmosphere ozone chemistry

   Geomagnetic storms triggered by coronal mass ejections and high-speed solar wind streams can lead to enhanced losses of energetic electrons from the radiation belts into the atmosphere, both during the […]

6. Ground-based estimates of outer radiation belt energetic electron precipitation fluxes into the atmosphere

   AARDDVARK data from a radio wave receiver in Sodankyla, Finland have been used to monitor transmissions across the auroral oval and just into the polar cap from the very low […]

7. Palaeoclimate Southern westerlies and CO2

   The Southern Hemisphere westerly winds affect the exchange of carbon dioxide between the ocean and atmosphere. Climate reconstructions from the southern mid-latitudes may reveal variability in the strength and position […]

8. Monitoring the Antarctic Circumpolar Current in the Drake Passage: Oceanography in Drake Passage: Wherefrom, Whereto and What in Between? Liverpool, United Kingdom, 26–27 October 2009

   The Antarctic Circumpolar Current (ACC), the world’s largest oceanic flow (∼135 million cubic meters per second), is an important component of the ocean climate, as it connects the three major […]

9. Seasonal dynamics and mortality rates of Calanus helgolandicus over two years at a station in the English Channel

   The stage-specific abundance and egg production rates of Calanus helgolandicus were determined on a near-weekly basis over 2 yr at a 50 m deep station in the SW English Channel […]

10. Observations of a noctilucent cloud above Logan, Utah (41.7oN, 111.8oW) in 1995

    A Rayleigh-scatter lidar has been operated at the Atmospheric Lidar Observatory (ALO) on the Utah State University (USU) campus (41.7°N, 111.8°W) since August 1993. During the morning of 22 June […]

11. Moulting reduces freeze susceptibility in the Antarctic mite Alaskozetes antarcticus (Michael)

    The effect of moulting on the cold hardiness of the oribatid mite Alaskozetes antarcticus (Michael) is investigated. Non moulting animals show clear seasonal patterns of cold hardiness with high supercooling […]

12. Tides and the flow of Rutford Ice Stream, West Antarctica

    [1] Surface speeds of Rutford Ice Stream, West Antarctica, are known to vary by around 10–20% (depending on location) with a fortnightly periodicity corresponding to a springneap tidal cycle. The […]
