The geomorphological effects of ice sliding over till, internal deformation of till and till sliding over bedrock are considered. Two questions are examined: (1) is the till-sheet flow unstable, i.e. […]
A simple one-dimensional sandpile model is constructed which possesses exact analytical solvability while displaying both scale-free behavior and fractal properties. The sandpile grows by avalanching on all scales, yet its […]
The upper part of the Jurassic‐Cretaceous Byers Group, exposed on Byers Peninsula in the South Shetland Islands, Antarctica, consists of 1.4 km of non‐marine strata assigned to the Cerro Negro […]
An objective assessment of maturity in the loliginid squid Loligo gahi was tested using a method developed for L. pealeii utilizing principal component and discriminant analyses. Samples were taken from […]
Causal mechanisms of mesocyclone and synoptic cyclone characteristics over the Northeast Atlantic and Nordic Seas are investigated using a 2-year database compiled from infrared satellite imagery. A strong seasonality is […]
Polar mesocyclones are subsynoptic-scale low pressure systems that form over high-latitude oceans in a cold air mass. It is known that these systems can be very vigorous but only relatively […]
Dinoflagellate cyst analysis has been undertaken on three Kasten cores taken from the Falkland Trough, Scotia Sea and Weddell Sea in the area of the Antarctic Peninsula. Two of these […]
Dinoflagellate cysts have been recovered from six long-term (1–2 yr) sediment trap moorings deployed in the Bellingshausen, Weddell and Scotia seas, Antarctica. These traps, mostly moored near the sea bed […]
The thermal sensitivity of mitochondrial function was investigated in the stenothermal Antarctic fish Lepidonotothen nudifrons. State 3 respiration increases with increasing temperature between 0 °C and 18 °C with a Q 10 […]
Cryoconite holes, supraglacial ponds and moulins of the Greenland Ice Sheet were surveyed for microbiota and meiofauna. These habitats are colonised by depauperate communities of widespread/cosmopolitan microbes, microalgae, rotifers and […]
Present radiative transfer methods in physically based energy budget models of snow do not include adequate spectral or directional resolution to deal with the scattering of solar radiation. This paper […]
A 181 m long ice core was drilled at 79°36′51″ S, 45°43′28″ W, near the summit of Berkner Island, Antarctica (886 m a.s.l.). Berkner Island is located between the Filchner […]
