The dynamics of Austfonna, Nordaustlandet, Svalbard: surface velocities, mass balance, and subglacial melt water
Read more of: The dynamics of Austfonna, Nordaustlandet, Svalbard: surface velocities, mass balance, and subglacial melt waterGlaciological measurements from Austfonna on Nordaustlandet, Svalbard, are needed as a prerequisite to mathematical modelling of ice-mass dynamics. Several upper and lower boundary conditions are set out in detail for […]

The reproductive energetics of gentoo (Pygoscelis papua) and macaroni (Eudyptes chrysolophus) penguins at South Georgia
Read more of: The reproductive energetics of gentoo (Pygoscelis papua) and macaroni (Eudyptes chrysolophus) penguins at South Georgia(1) The doubly-labelled water method was used in the first comprehensive study of penguin energetics throughout the reproduction and moult season, comparing gentoo penguins (inshore feeding, sexually monomorphic, share breeding […]

Science in Antarctica – a matter of quality
Read more of: Science in Antarctica – a matter of qualityAntarctic research has progressed steadily from the era of reconnaissance studies into a period of problem-oriented scientific investigation. The International Geophysical Year and the intensive work of the 1960s and […]

Physiological constraints on living and fossil brachiopods
Read more of: Physiological constraints on living and fossil brachiopodsAsh-free-dry-weight determinations for a representative range of living brachiopod genera have revealed that a consistently high proportion of total organic mass is contained within the shell, partly as the organic […]

A 30-year simulation of the outer electron radiation belt
Read more of: A 30-year simulation of the outer electron radiation beltAs society becomes more reliant on satellite technology, it is becoming increasingly important to understand the radiation environment throughout the Van Allen radiation belts. Historically most satellites have operated in […]

Vertical Structure of Diurnal Englacial Hydrology Cycle at Helheim Glacier, East Greenland
Read more of: Vertical Structure of Diurnal Englacial Hydrology Cycle at Helheim Glacier, East GreenlandThe interior dynamics of Helheim Glacier were monitored using an autonomous phase‐sensitive radio‐echo sounder (ApRES) during two consecutive summers. The return signals from all observational sites exhibited strong non‐tidal, depth‐dependent […]

Salinity control of thermal evolution of late summer melt ponds on Arctic sea ice
Read more of: Salinity control of thermal evolution of late summer melt ponds on Arctic sea iceThe thermal evolution of melt ponds on Arctic sea ice was investigated through a combination of autonomous observations and two‐dimensional high‐resolution fluid dynamics simulations. We observed one relatively fresh pond […]

Precipitation instruments at Rothera Station, Antarctic Peninsula: a comparative study
Read more of: Precipitation instruments at Rothera Station, Antarctic Peninsula: a comparative studyDirect measurement of precipitation in the Antarctic using ground-based instruments is important to validate the results from climate models, reanalyses and satellite observations. Quantifying precipitation in Antarctica faces many unique […]
