TL;DR: In this article, a new method combining wet extraction, gas chromatography and mass spectrometry was developed for high-precision, simultaneous measurements of eight air components (CH4, N2O and CO2 concentrations, δ15N, N 2O, O 2, δO2/N2, O 3, O 4, O 2 and O 4 ) from an ice core sample of ~60'g.
Journal ArticleDOI

TL;DR: The TALDICE-deep1 chronology as discussed by the authors extends the age scale of the TALos Dome Ice CorE to MIS 10.1-343 ka (1548m depth) and identifies both MIS 7 and 9 warm stages, which show specificities in the δD signal.
Journal ArticleDOI

TL;DR: In this paper, surface, snow pit, and ice core observations made in this study during summer field seasons from 2008-2009 to 2012-2013, supplemented by automated weather station (AWS) data with short-and long-wave radiation sensors, revealed that such crusts formed during relatively low-wind, low-humidity, clear-sky periods with intense daytime sunshine.

TL;DR: The PAGES Antarctica 2k working group as discussed by the authors built an enlarged database of ice core water stable isotope records from Antarctica, consisting of 112 records, binned at 5 and 10-year resolution, for 7 climatically-distinct regions covering the Antarctic continent.
