Equal Opportunities on Ice: Examining gender and institutional change at the British Antarctic Survey, 1975-1996
… dismantling of a discriminatory policy at the British Antarctic Survey (BAS), and the corresponding progress toward women’s equality in Antarctica. It ostensibly traces the evolution of BAS’s exclusionary policy toward women in Antarctica, beginning with the passage of the 1975 Sex …

A policy for antarctic tourism: conflict or cooperation?
The Antarctic tourism industry is described and assessed. Tourist numbers are established. The regulatory framework for Antarctic tourism is explained and problems for policy makers are identified. Tourism policies of the British Antarctic Survey, United States Antarctic Program and other Treaty …

The provision of health care in remote hostile environments.
… concentrating on the offshore oil industry and Antarctic populations. An understanding of associated environmental hazards is essential for adequate health care and particular attention is paid to the hyperbaric environment and to environmental heat and cold. The basic medical problems in remote …

Chemistry of the sea ice/ snowpack/ atmosphere system in coastal Antarctica
… 2007, year round measurements were made at the British Antarctic Survey station Halley, in coastal Antarctica, using a Chemical Ionisation Mass Spectrometer (CIMS). During specific periods in the spring the CIMS was configured to measure concentrations of BrO, Br2 and BrCl. In addition, …

Computational Tools for Metabolic Modeling and Gene Duplication Analysis
… a simplified model of aerobic respiration for an Antarctic species, and, given a gene expression dataset across different temperatures, we develop two different machine learning approaches to model the fluxes through the metabolic network. The first approach we use is based on denoising …

Aerosol chemistry and air-snow transfer in coastal Antarctica
… sources of aerosol particles reaching coastal Antarctica, and the processes that control aerosol deposition to the snow surface and inclusion into the ice.<br></br><br></br>Daily collections of aerosol particles and surface snow samples were made from British Antarctic Survey base, Halley. …

Understanding how low energy electrons control the variability of the Earth's electron radiation belts
… low energy boundary conditions for the British Antarctic Survey Radiation Belt Model (BAS-RBM). This new low energy boundary condition from LEO data has a higher spatial and temporal resolution, and a broader L* coverage, than previous work. The impact of variations in the seed …

Electron transport, acceleration and loss in Earth's outer radiation belt
… rapid storm time flux variations using the British Antarctic Survey radiation belt model (BAS-RBM). A set of events involving rapid drops in electron flux across a range of energies at high $L$ shells near the magnetopause were analysed. The observations were compared to event-specific last …

Ecophysiology, Morphology and Phylogeography of Insects in the Scotia Arc
… Georgia and the South Orkney Islands and the Antarctic Peninsula, is home to a range of understudied insect species which are constantly exposed to extreme environmental conditions. To help reduce the amount of uncertainty surrounding insect taxa evolution in the region, we aimed to elucidate …

Ice core methane and carbon monoxide as tracers of the terrestrial biosphere since the pre-industrial
… process by which snow transforms into ice, few Antarctic ice core records have been able to capture highly resolved atmospheric information over the most recent centuries. Instead, low-resolution measurements of firn air have often been used to bridge the gap between the end of ice core gas …

A historical geography of Halley research station, Antarctica, 1956 – present
… geographies of Halley research station, a British research station in East Antarctica. This study is the first in-depth history of Halley station, a site unique even among the already remarkable category of Antarctic research stations. Established for the International Geophysical Year of …

Understanding past and future changes in northern Fennoscandian snow cover.
In this project, a combination of field measurements, remote sensing data and regional climate model outputs were used to study recent and projected future changes in Northern Fennoscandian snow cover. The research questions considered in this thesis are: What are the uncertainties in remote …
