1. Sex-specific foraging strategies throughout the breeding season in a tropical, sexually monomorphic small petrel

   Two hypotheses have been proposed to explain sex-related differences in foraging in sexually monomorphic seabirds. The ‘intersexual competition’ hypothesis suggests that parents are in competition and that the dominated sex […]

2. Greater supply of Patagonian-sourced detritus and transport by the ACC to the Atlantic sector of the Southern Ocean during the last glacial period

   Reconstructing past detrital flux and provenance in the SouthernOcean provides information about changes in source regions associated with climate variations and transport pathways. We present a LastGlacial Maximum (LGM) to […]

3. Seasonal and spatial dynamics of iron availability in the Scotia Sea

   The Southern Ocean is the world’s largest high nutrient low chlorophyll (HNLC) region. However, satellite images highlight several areas associated with island chains and shallow topographic features which display high […]

4. On the nature of a short-period mesospheric gravity wave propagation over Halley, Antarctica

   As part of a collaborative program between British Antarctic Survey and Utah State University, measurements were made using an all-sky airglow imager located at the U.K. Halley Station (76°S, 27°W) […]

5. Energy and ozone fluxes over sea ice

   We present surface layer measurements made over Hudson Bay seaice during February/March 2008 from the COBRA (Impact of combined iodine and bromine release on the Arctic atmosphere) experiment which formed […]

6. Antarctic palaeo-ice streams

   We review the geomorphological, sedimentological and chronological evidence for palaeo-icestreams on the continental shelf of Antarctica and use this information to investigate basal conditions and processes, and to identify factors […]

7. Intrinsic determinants of a population trend in timing of breeding in the wandering albatross

   Numerous studies of wild animal species have documented that population level responses to environmental change are underpinned by individual level phenotypic plasticity. However, where the relationship between an individual trait […]

8. The deglacial history of NW Alexander Island, Antarctica, from surface exposure dating

   Recent changes along the margins of the Antarctic Peninsula, such as the collapse of the Wilkins Ice Shelf, have highlighted the effects of climatic warming on the Antarctic Peninsula Ice […]

10. Factors influencing the stable carbon isotopic composition of suspended and sinking organic matter in the coastal Antarctic sea ice environment

    A high resolution time-series analysis of stable carbon isotopic signatures in particulate organic carbon (δ13CPOC) and associated biogeochemical parameters in sea ice and surface waters provides an insight into the […]

11. Total ozone dependence of the difference between the empirically corrected EP-TOMS and high-latitude station datasets

    A comparison was made of the ground-based and satellite total ozone content (TOC) measurements in the atmosphere over the Antarctic stations Vernadsky, Halley and Amundsen–Scott and the Arctic station Barrow. […]

12. Antarctic biology, the International Polar Year, and beyond

    As we draw towards the end of the massive effort that has been the International Polar Year (IPY), it is opportune to consider what impact it has had on Antarctic […]
