New analytical solutions describing the effects of small-amplitude perturbations in boundary data on flow in the shallow-ice-stream approximation are presented. These solutions are valid for a non-linear Weertman-type sliding law […]
An optimal estimation method for simultaneously determining both basal slipperiness and basal topography from variations in surface flow velocity and topography along a flow line on ice streams and ice […]
The diet of brown skuas (Catharacta antarctica lonnbergi) on Bird Island, South Georgia was assessed using a combination of stable isotope analysis (SIA) and mixing model techniques. We found evidence […]
The Antarctic Peninsula has experienced a dramatic increase in temperature and the loss of ca. 14,000 km2 of ice-shelf area in recent years. During this time George VI Ice Shelf […]
Gravity waves play an important role in determining the structure and dynamics of the mesopause region. In this study the Imaging Riometer for Ionospheric Studies (IRIS) at Halley, Antarctica (76S, […]
Microstructure and hydrographic observations, during September 2007 in the boundary current on the East Siberian continental slope, document upper ocean stratification and along-stream water mass changes. A thin warm surface […]
The change from a glacial to an interglacial climate is paced by variations in Earth’s orbit. However, the detailed sequence of events that leads to a glacial termination remains controversial. […]
Surveys of Euphausia superba often target localised shelves and ice edges where their growth rates and predation losses are atypically high. Emphasis on these areas has led to the current […]
The growth (melt) rate of frazil ice is governed by heat transfer away from (towards) the ice crystal, which can be represented by the Nusselt number. We discuss choices for […]
A drag law accounting for Ekman rotation adjacent to a flat, horizontal boundary is proposed for use in a plume model that is written in terms of the depth-mean velocity. […]
