TL;DR: In this paper, a glacial climate record derived from an ice core from Dronning Maud Land, Antarctica, which represents South Atlantic climate at a resolution comparable with the Greenland ice core records was presented.

TL;DR: Continuous chemical proxy data spanning the last eight glacial cycles from the Dome C Antarctic ice core constrain winter sea-ice extent in the Indian Ocean, Southern Ocean biogenic productivity and Patagonian climatic conditions and observe large glacial–interglacial contrasts in iron deposition, which is infer reflects strongly changing Patagonia conditions.

TL;DR: In this article, the authors present a new multiproxy data set of sea surface temperatures (SST), dust and iron supply, and marine export productivity from the marine sediment core PS2489-2/ODP Site 1090 located in the subantarctic Atlantic, that allow them to evaluate various hypotheses on the role of the Southern Ocean (SO) in modulating atmospheric CO2 concentrations back to 11 Ma.

TL;DR: In this paper, the authors used a simple conceptual transport model to estimate that transport can explain only 40% of the atmospheric dust concentration changes in Antarctica, while factor 5-10 changes occurred.

TL;DR: In this article, a series of dated snow samples, covering the period from 1834 to 1990, collected at remote, low accumulation sites in Coats Land, Antarctica, were determined by ultrasensitive inductively coupled sector field mass spectrometry in ultraclean conditions.
