Physiological flexibility: the key to success and survival for Antarctic fairy shrimps in highly fluctuating extreme environments
Read more of: Physiological flexibility: the key to success and survival for Antarctic fairy shrimps in highly fluctuating extreme environments1. The anostracan fairy shrimp Branchinecta gaini inhabits one of the most hostile environments on earth, living in pools and lakes in Antarctica. Between January 2002 and January 2003 temperatures […]

Magnetic local time, substorm, and particle precipitation-related variations in the behaviour of SuperDARN Doppler spectral widths
Read more of: Magnetic local time, substorm, and particle precipitation-related variations in the behaviour of SuperDARN Doppler spectral widthsSuper Dual Auroral Radar Network (DARN) radars often detect a distinct transition in line-of-sight Doppler velocity spread, or spectral width, from 200 m s(-1) at higher latitude. They also detect […]

A ‘low-level’ explanation for the recent large warming event trend over the western Antarctic Peninsula involving blocked winds and changes in zonal circulation
Read more of: A ‘low-level’ explanation for the recent large warming event trend over the western Antarctic Peninsula involving blocked winds and changes in zonal circulation[1] We demonstrate a mechanism whereby the impact of stronger circumpolar westerly winds on the mountains of the Antarctic Peninsula contributes significantly to the enhanced warming trend observed over its […]

Circulation and water masses beneath the northern Ronne Ice Shelf, Antarctica
Read more of: Circulation and water masses beneath the northern Ronne Ice Shelf, AntarcticaWe present oceanographic data from beneath the northern Ronne Ice Shelf. The data were collected during the austral summer of 2002–2003 from four sites located near the ice front in […]

Interannual variability and ventilation timescales in the ocean cavity beneath Filchner-Ronne Ice Shelf, Antarctica
Read more of: Interannual variability and ventilation timescales in the ocean cavity beneath Filchner-Ronne Ice Shelf, Antarctica[1] Multiyear time series of ocean current and temperatures from beneath Filchner-Ronne Ice Shelf, Antarctica, demonstrate both seasonal and interannual variability. The seasonal signal is visible at all measurement sites, […]
