Extending the Antarctic meteorological record using ice-sheet temperature profiles
Read more of: Extending the Antarctic meteorological record using ice-sheet temperature profilesTwo vertical ice temperature profiles from locations in the Antarctic Peninsula unaffected by meltwater are presented. A simple time-dependent heat diffusion-advection model is used to infer broad surface temperature variations […]

Measurements of seasonal rates and annual budgets of organic carbon fluxes in an Antarctic coastal environment at Signy Island, South Orkney Islands, suggest a broader balance between production and decomposition
Read more of: Measurements of seasonal rates and annual budgets of organic carbon fluxes in an Antarctic coastal environment at Signy Island, South Orkney Islands, suggest a broader balance between production and decompositionWe report here the first comprehensive seasonal study of benthic microbial activity in an Antarctic coastal environment. Measurements were made from December 1990 to February 1992 of oxygen uptake and […]

Evidence for winter/spring denitrification of the stratosphere in the nitrate record of Antarctic firn cores
Read more of: Evidence for winter/spring denitrification of the stratosphere in the nitrate record of Antarctic firn coresA firn core from within the polar vortex in the Weddell Sea sector of Antarctica shows nitrate peaks that occur in the spring or early summer. They are far less […]
