Changes in sea ice conditions and atmospheric circulation over the Southern Ocean play an important role in modulating Antarctic climate. However, observations of both sea ice and wind conditions are limited in Antarctica and the Southern Ocean, both temporally and spatially…
Atrialwas undertaken of two techniques for assessing the physical condition ofwalking tracks (trails) over extended distances. A distance-based technique, in which categorical measurements were made at regular spatial intervals, proved to be sufficiently … reliable to warrant further development.
We present a reconstruction of Antarctic mean surface … temperatures over the past two centuries based on water … stable isotope records from high-resolution, precisely dated … ice cores. Both instrumental and reconstructed temperatures … indicate large interannual to decadal scale variability…
Antarctic snowfall exhibits substantial variability over a range of time scales, with consequent … impacts on global sea level and the mass balance of the ice sheets. To assess how snowfall has … affected the thickness of the ice sheets in Antarctica and to provide an extended perspective…
Most of what has been said about modern Antarctic climate change is based on studies of … meteorological observations that extend back the 1950s. Most attention to Antarctic ice core … records is focused on the timescale of glacial-interglacial cycles.
ABSTRACT. We present highly resolved, annually dated, calibrated proxies for atmospheric circulation … from several Antarctic ice cores (ITASE (International Trans-Antarctic Scientific Expedition), Siple … Dome, Law Dome)…
An updated compilation of published and new data of major-ion (Ca, Cl, K, Mg, Na, NO3, SO4) and methylsulfonate (MS) concentrations in snow from 520 Antarctic sites is provided by the … national ITASE (International Trans-Antarctic Scientific Expedition) programmes of Australia, Brazil, China…
A sparse network of meteorological observations in Antarctica extends back only to the late 1950s, making it difficult to characterize Antarctica's climate behavior in the context of natural climate variability and global warming. We show that composites of stable isotope (dD and d18O)…
