1. Tracer-derived freshwater composition of the Siberian continental shelf and slope following the extreme Arctic summer of 2007

   We investigate the freshwater composition of the shelf and slope of the Arctic Ocean north of the New Siberian Islands using geochemical tracer data (δ18O, Ba, and PO4*) collected following […]

2. Analytical solutions for the surface response to small amplitude perturbations in boundary data in the shallow-ice-stream approximation

   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 […]

3. On the limit to resolution and information on basal properties obtainable from surface data on ice streams

   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 […]

4. Diet, individual specialisation and breeding of brown skuas (Catharacta antarctica lonnbergi): An investigation using stable isotopes

   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 […]

5. The Holocene history of George VI ice shelf, Antarctic Peninsula from clast-provenance analysis of epishelf lake sediments

   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 […]

7. Observing mesospheric gravity waves with an imaging riometer.

   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, […]

9. Vertical mixing at intermediate depths in the Arctic boundary current

   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 […]

10. Glacial terminations as southern warmings without northern control

    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. […]

11. Oceanic circumpolar habitats of Antarctic krill

    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 […]

12. On the Nusselt number for frazil ice growth – a correction to “Frazil evolution in channels” by Lars Hammar and Hung-Tao Shen.

    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 […]
