Trace ion analysis for a suite of chemistry species (including chloride, sodium, sulphate, nitrate and methanesulphonic acid) has been performed on the deep Dome Summit South … (DSS) ice core from Law Dome, East Antarctica covering the period 9000 years before … present.
Knowledge of environmental variability and change during the … Medieval Climate Anomaly (MCA ; ~800 to 1300 - 1400 AD) in the Southern Hemisphere has been characterized by a La Nina-like mean climate state in the Pacific Basin…
The Antarctic climate system varies on timescales from orbital, through millennial to sub-annual, and is closely coupled to other parts of the global climate system.
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.
From its original formulation in 1990 the International Trans-Antarctic Scientific Expedition … (ITASE) has had as its primary aim the collection and interpretation of a continent-wide array of … environmental parameters assembled through the coordinated efforts of scientists from several nations.
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…
The Southern Hemisphere westerlies in the southwest Pacific are known to have waxed and waned numerous times during the last … two glacial cycles, though even semi-continuous histories of the westerlies extend back no more than about 20,000 years.
