Last glacial-interglacial sea-ice cover in the SW Atlantic and its potential role in global deglaciation
Read more of: Last glacial-interglacial sea-ice cover in the SW Atlantic and its potential role in global deglaciationSea-ice growth and decay in Antarctica is one of the biggest seasonal changes on Earth, expanding ice cover from 4 106 km2 to a maximum of 19 106 km2 during […]

Different means to the same end: Long-distance migrant seabirds from two colonies differ in behaviour, despite common wintering grounds
Read more of: Different means to the same end: Long-distance migrant seabirds from two colonies differ in behaviour, despite common wintering groundsAlthough seabirds that are trans-equatorial migrants show apparently broad overlap among populations in the non-breeding season, such large-scale pattern may conceal subtle but nevertheless key differences in migratory behaviour. These […]

Widespread low rates of Antarctic glacial isostatic adjustment revealed by GPS observations
Read more of: Widespread low rates of Antarctic glacial isostatic adjustment revealed by GPS observationsBedrock uplift in Antarctica is dominated by a combination of glacial isostatic adjustment (GIA) and elastic response to contemporary mass change. Here, we present spatially extensive GPS observations of Antarctic […]

Daytime D region parameters from long-path VLF phase and amplitude
Read more of: Daytime D region parameters from long-path VLF phase and amplitudeObserved phases and amplitudes of VLF radio signals propagating on very long paths are used to validate electron density parameters for the lowest edge of the (D region of the) […]

Anthropogenic impacts on marine ecosystems in Antarctica
Read more of: Anthropogenic impacts on marine ecosystems in AntarcticaAntarctica is the most isolated continent on Earth, but it has not escaped the negative impacts of human activity. The unique marine ecosystems of Antarctica and their endemic faunas are […]

Dynamic subauroral ionospheric electric fields observed by the Falkland Islands radar during the course of a geomagnetic storm
Read more of: Dynamic subauroral ionospheric electric fields observed by the Falkland Islands radar during the course of a geomagnetic stormWe present an analysis of ionospheric electric field data observed during a geomagnetic storm by the recently deployed HF radar located on the Falkland Islands. On 3 August 2010 at […]

On high-resolution sampling of short ice cores: dating and temperature information recovery from Antarctic Peninsula virtual cores
Read more of: On high-resolution sampling of short ice cores: dating and temperature information recovery from Antarctic Peninsula virtual coresRecent developments in ice melter systems and continuous flow analysis (CFA) techniques now allow higher-resolution ice core analysis. Here, we present a new method to aid interpretation of high-resolution ice […]

Bayesian Glaciological Modelling to quantify uncertainties in ice core chronologies
Read more of: Bayesian Glaciological Modelling to quantify uncertainties in ice core chronologiesValuable information about the environment and climate of the past is preserved in ice cores which are drilled through ice sheets in polar and alpine regions. A pivotal part of […]

Direct observations of nitric oxide produced by energetic electron precipitation into the Antarctic middle atmosphere
Read more of: Direct observations of nitric oxide produced by energetic electron precipitation into the Antarctic middle atmosphereWe report the first ground-based passive microwave observations made from Troll station, Antarctica, which show enhanced mesospheric nitric oxide (NO) volume mixing ratio reaching levels of 1.2 ppmv, or 2–3 […]

East Antarctic rifting triggers uplift of the Gamburtsev Mountains
Read more of: East Antarctic rifting triggers uplift of the Gamburtsev MountainsThe Gamburtsev Subglacial Mountains are the least understood tectonic feature on Earth, because they are completely hidden beneath the East Antarctic Ice Sheet. Their high elevation and youthful Alpine topography, […]
