TL;DR: A marine glacial record from the upper 600 m of the AND-1B sediment core recovered from beneath the northwest part of the Ross ice shelf is presented and well-dated, ∼40-kyr cyclic variations in ice-sheet extent linked to cycles in insolation influenced by changes in the Earth’s axial tilt (obliquity) during the Pliocene are demonstrated.

TL;DR: A north-to-south directionality of the abrupt climatic signal is demonstrated, which is propagated to the Southern Hemisphere high latitudes by oceanic rather than atmospheric processes, which confirms a central role for ocean circulation in the bipolar seesaw.
Journal ArticleDOI

TL;DR: This article presented the WD2014 chronology for the upper part of the West Antarctic Ice Sheet (WAIS) Divide (WD) ice core, which is based on counting of annual layers observed in the chemical, dust and electrical conductivity records.
Journal ArticleDOI
Distinguishing subglacial till and glacial marine diamictons in the western Ross Sea, Antarctica: Implications for a last glacial maximum grounding line
TL;DR: An analysis of marine sediment cores collected from the western Ross Sea during cruises Eltanin 32 and 52 and Deep Freeze 80 and 87 indicate that subglacial till does not extend to the continental shelf edge as mentioned in this paper.
Journal ArticleDOI
Mantle to surface degassing of alkalic magmas at Erebus volcano, Antarctica
Clive Oppenheimer,Clive Oppenheimer,Roberto Moretti,Roberto Moretti,Philip R. Kyle,Al Eschenbacher,Jacob B. Lowenstern,Richard L. Hervig,Nelia W. Dunbar +8 more
TL;DR: In this paper, the authors examined the degassing of the magmatic system at Erebus volcano using melt inclusion data and high temporal resolution open-path Fourier transform infrared (FTIR) spectroscopic measurements of gas emissions from the active lava lake.
