The El Niño-Southern Oscillation and Antarctica
This 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 […]

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.

Winter distribution and behaviour of gentoo penguins Pygoscelis papua at South Georgia
Read more of: Winter distribution and behaviour of gentoo penguins Pygoscelis papua at South GeorgiaKnowledge of the spatial and temporal dynamics of foraging penguins is important to our understanding of the Southern Ocean marine ecosystem. We use satellite tracking to provide the first data […]
