The El Niño-Southern Oscillation and Antarctica
Read more of: The El Niño-Southern Oscillation and AntarcticaThis paper reviews our understanding of how the effects of the El Nino-southern oscillation (ENSO) might be transmitted from the tropical Pacific Ocean to the Antarctic, and examines the evidence […]

Assessing the effects of low temperature on the establishment potential in Britain of the non-native biological control agent Eretmocerus eremicus
Read more of: Assessing the effects of low temperature on the establishment potential in Britain of the non-native biological control agent Eretmocerus eremicusEretmocerus eremicus is a parasitoid wasp that is not native to Britain. It is a biological control agent of glasshouse whitefly and has recently been released under licence in Britain […]

The relationship between variations of the atmospheric electric field in the southern polar region and thunderstorm activity
Read more of: The relationship between variations of the atmospheric electric field in the southern polar region and thunderstorm activityObservations of the atmospheric, near-surface vertical electric field component E-z have been carried out at the Russian-Antarctic station, Vostok, since 1998 under the framework of a cooperative Russian-Australian project. Only […]

A new Snow-SVAT to simulate the accumulation and ablation of seasonal snow cover beneath a forest canopy
Read more of: A new Snow-SVAT to simulate the accumulation and ablation of seasonal snow cover beneath a forest canopyA new snow-soil-vegetation-atmosphere transfer (Snow-SVAT) scheme, which simulates the accumulation and ablation of the snow cover beneath a forest canopy, is presented. The model was formulated by coupling a canopy […]

Marine predators at South Georgia: an overview of recent bio-logging studies
Read more of: Marine predators at South Georgia: an overview of recent bio-logging studiesThere is a unique diversity and density of land-based marine predators breeding at Bird Island, South Georgia, operating at a wide variety of spatial and temporal scales. These provide exceptional […]

Image analysis of color aerial photography to estimate penguin population size
Read more of: Image analysis of color aerial photography to estimate penguin population sizePenguin populations are potentially sensitive indicators of ecological change in Antarctic and sub-Antarctic marine ecosystems. Aerial photographic surveys provide the most robust method for estimating breeding population size, particularly for […]

Tissue distribution of retinoids in common dolphins Delphinus delphis
Read more of: Tissue distribution of retinoids in common dolphins Delphinus delphisExposure to organochlorines induces retinoid deficiency in mammals; hence, retinoids are potential biomarkers of the impact of these pollutants. Appropriate target tissues to monitor retinoids in cetaceans have not been […]

Retinoid and lipid patterns in the blubber of common dolphins (Delphinus delphis): implications for monitoring vitamin A status
Read more of: Retinoid and lipid patterns in the blubber of common dolphins (Delphinus delphis): implications for monitoring vitamin A statusWe determined retinoid concentrations in various body positions of the blubber of 25 common dolphins (Delphinus delphis) to study topographical variation in concentrations. Specimens were obtained from incidental catches and […]

Tracking passive drifters in a high resolution ocean model: implications for interannual variability of larval krill transport to South Georgia
Read more of: Tracking passive drifters in a high resolution ocean model: implications for interannual variability of larval krill transport to South GeorgiaA particle tracking scheme that uses velocity output from an interannually varying forced run of a global ocean circulation model (Parallel Ocean Climate Model; POCM_4C) allows variability in the transport […]

An evaluation of two spatial interpolation techniques in global sea-surface temperature reconstructions: Last Glacial Maximum and Pliocene case studies
Read more of: An evaluation of two spatial interpolation techniques in global sea-surface temperature reconstructions: Last Glacial Maximum and Pliocene case studiesGlobal estimates of sea-surface temperature (SST) distributions represent an important prescribed boundary condition for atmosphere-only general circulation models (AGCMs) which aim to Simulate the behaviour of the past climate system.
