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: In this article, reycled Cretaceous and Cenozoic marine microfossils have been recovered from samples of the Pliocene Sinus Formation, collected from outcrops in the Reedy, Beardmore, and Ferrar glacier areas of the Transantarctic Mountains between lat 77° and 86°S.

TL;DR: Sediment data from shallow marine cores in the western Ross Sea are presented that exhibit well dated cyclic variations, and which link the extent of the East Antarctic ice sheet directly to orbital cycles during the Oligocene/Miocene transition, suggesting that orbital influences at the frequencies of obliquity and eccentricity controlled the oscillations of the ice margin at that time.

TL;DR: The authors reviewed the Late Cenozoic history of the Transantarctic Mountains and flanking sedimentary basins with emphasis on the debate between the'stabilist' view of Antarctic ice sheet history and our favored multi-glacial dynamic ice sheet model.

TL;DR: An exceptional triple palynological signal (unusually high abundance of marine, freshwater, and terrestrial palynomorphs) recovered from a core collected during the 2007 ANDRILL (Antarctic geologic drilling program) campaign in the Ross Sea, Antarctica, provides constraints for the Middle Miocene Climatic Optimum as discussed by the authors.
