The mechanism by which the freeze susceptible Arctic collembolan Onychiurus arcticus survives winter temperatures of −25°C in the field is not fully understood but exposure to sub-zero temperatures (e.g. −2.5°C) […]
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, […]
Aerosol 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, […]
Aerosol 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 […]
At 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, […]
The 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 […]
Characterised 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 […]
The 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 […]
Mega-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 […]
