1. Examining Holocene stability of Antarctic Peninsula ice shelves

   Temperatures on the Antarctic Peninsula are increasing at a rate of 3.4°C per century, more than five times the global mean. At the same time, the region’s ice shelves have […]

2. Oil pollution in the Antarctic terrestrial environment

   Fuel oil has been extensively relied upon as an energy source since the earliest discovery and exploration of Antarctica. During this time oil spills have occurred, particularly around established research […]

3. Planetary wave trends in the lower thermosphere – evidence for 22-year solar modulation of the quasi 5-day wave

   Geomagnetic data from five northern hemisphere observatories at latitudes ranging from 22 degrees N to 67 degrees N have been used to investigate long-term trends in planetary wave activity in […]

4. A microwave radiometer for the remote sensing of nitric oxide and ozone in the middle atmosphere

   Nitric oxide, which reacts catalytically to destroy ozone, can be produced in great abundance in the middle atmosphere during energetic particle precipitation triggered by solar storms. During the Antarctic winter, […]

5. Spring stopover routines in Russian Barnacle Geese Branta leucopsis tracked by resightings and geolocation

   By attaching 9-g loggers (recording dusk and dawn times to a memory chip) to the coded leg rings of Barnacle Geese Branta leucopsis caught in a breeding colony at Tobseda […]

7. Diet variability and reproductive performance of macaroni penguins Eudyptes chrysolophus at Bird Island, South Georgia

   We analysed summer diet and fledging mass of macaroni penguins Eudyptes chrysolophus breeding at Bird Island, South Georgia, during the crèche period (January and February) between 1989 and 2010. Crustaceans […]

8. Advances in the in-field detection of microorganisms in ice

   The historic view of ice-bound ecosystems has been one of a predominantly lifeless environment, where microorganisms certainly exist but are assumed to be either completely inactive or in a state […]

9. Challenges to the future conservation of the Antarctic

   The Antarctic Treaty System, acknowledged as a successful model of cooperative regulation of one of the globe’s largest commons ( 1), is under substantial pressure. Concerns have been raised about […]

10. The 600 yr eruptive history of Villarrica Volcano (Chile) revealed by annually laminated lake sediments

    Lake sediments contain valuable information about past volcanic and seismic events that have affected the lake catchment, and they provide unique records of the recurrence interval and magnitude of such […]

11. Halogen activation via interactions with environmental ice and snow in the polar lower troposphere and other regions

    The role of ice in the formation of chemically active halogens in the environment requires a full understanding because of its role in atmospheric chemistry, including controlling the regional atmospheric […]

12. Late Quaternary grounded ice extent in the Filchner Trough, Weddell Sea, Antarctica: new marine geophysical evidence

    The Last Glacial Maximum (LGM; ca 23–19 ka BP) extent of grounded ice in the Filchner Trough, a major cross shelf trough extending seaward from the Filchner Ice Shelf in […]
