TL;DR: In this article, a database of surface Antarctic snow isotopic composition is constructed using available measurements, with an estimate of data quality and local variability, and the capacity of theoretical isotopic, regional, and general circulation atmospheric models to reproduce the observed features and assess the role of moisture advection in spatial deuterium excess fluctuations.

TL;DR: 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, Germany, Italy, Japan, Korea, New Zealand, Norway, United Kingdom, the United States and the national Antarctic programme of Finland as mentioned in this paper.

TL;DR: Arsenic variability records are preserved in snow and ice cores and can be utilized to reconstruct air pollution history as mentioned in this paper, which can be used to reconstruct atmospheric pollution history using ICP-SFMS (CCI, University of Maine, USA).

TL;DR: A 49.9m firn-ice core recovered from the King George Island ice cap (690 m above sea level) in the summer of 1995-96 was analyzed for stable isotope composition and major anionic species.

TL;DR: In this paper, the authors investigated the influence of climate variables on the elemental concentrations at the Mount Johns (MJ) site and found that marine derived trace element concentrations are strongly influenced by sea ice concentration and sea surface temperature anomalies.
