Coastal Antarctic aerosol and snowfall chemistry
Aerosol samples have been collected at three stations on the coast of Antarctica. At Dumont d’Urville Station, samples have been collected for 4 years, at Halley Station for 2 years, […]

Relationship between chemistry of air, fresh snow and firn cores for aerosol species in coastal Antarctica
Read more of: Relationship between chemistry of air, fresh snow and firn cores for aerosol species in coastal AntarcticaAerosol and fresh snow concentrations have been determined at three coastal Antarctic stations, Dumont d’Urville, Halley, and Neumayer. Model estimates suggest that dry deposition, including that caused by wind pumping, […]

Concentrations and seasonal cycle of black carbon in aerosol at a coastal Antarctic station
Read more of: Concentrations and seasonal cycle of black carbon in aerosol at a coastal Antarctic stationAerosol black carbon concentrations have been measured between 1992 and 1995 at Halley station using an aethalometer. The complete record is dominated by a number of events of high concentration […]

Development, dispersal and recruitment: A paradox for survival among Antarctic fish
Read more of: Development, dispersal and recruitment: A paradox for survival among Antarctic fishAt first sight, the life-history strategies adopted by Antarctic fish appear to be a paradox. The majority of fish species are demersal and inhabit the peri-Antarctic islands that are isolated, […]

Morphological and molecular characterization of salps (Thalia spp.) from the Tristan da Cunha archipelago
Read more of: Morphological and molecular characterization of salps (Thalia spp.) from the Tristan da Cunha archipelagoThe identification of salp species by morphological features alone can be challenging. This study combined morphological and molecular approaches to characterize different salp reproductive forms (oozooids and blastozooids) collected from […]

Deep ocean carbonate ion increase during mid Miocene CO2 decline
Read more of: Deep ocean carbonate ion increase during mid Miocene CO2 declineCharacterised by long term cooling and abrupt ice sheet expansion on Antarctica ~14 Ma ago, the mid Miocene marked the beginning of the modern ice-house world, yet there is still little […]

Spatial patterns in the vertical structure of euphausiids in Gullmarsfjord, Sweden: Identifying influences on bilayer formation and distribution
Read more of: Spatial patterns in the vertical structure of euphausiids in Gullmarsfjord, Sweden: Identifying influences on bilayer formation and distributionThe formation of two vertically discrete layers (bilayers) at night-time is a commonly observed phenomenon in zooplankton and is regularly found in Gullmarsfjord, a fjord with a 50 m sill […]

Size, shape and spatial arrangement of mega-scale glacial lineations, and implications for ice stream basal processes
Read more of: Size, shape and spatial arrangement of mega-scale glacial lineations, and implications for ice stream basal processesMega-scale glacial lineations (MSGLs) are a characteristic landform on ice stream beds. Solving the puzzle of their formation is key to understanding how ice interacts with its bed and how […]

High-throughput sequencing reveals inbreeding depression in a natural population
Read more of: High-throughput sequencing reveals inbreeding depression in a natural populationProxy measures of genome-wide heterozygosity based on approximately 10 microsatellites have been used to uncover heterozygosity fitness correlations (HFCs) for a wealth of important fitness traits in natural populations. However, […]

Foraging range and habitat associations of non‑breeding Tristan albatrosses: overlap with fisheries and implications for conservation
Read more of: Foraging range and habitat associations of non‑breeding Tristan albatrosses: overlap with fisheries and implications for conservationThe Tristan albatross Diomedea dabbanena is Critically Endangered: >99% of adults breed at Gough Island, central South Atlantic Ocean, where chicks are threatened by introduced predators. At sea they mostly […]
