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: Evidence for a major expansion of an ice sheet in the Ross Sea that began at ∼3.3 Ma, followed by a coastal sea surface temperature cooling of ∼2.5 °C, indicates an additional role played by southern high-latitude cooling during development of the bipolar world.

TL;DR: It is shown, using marine geological and geophysical data from the continental shelf seaward of the Aurora subglacial basin, that marine-terminating glaciers existed at the Sabrina Coast by the early to middle Eocene epoch, implying a dynamic EAIS response with continued anthropogenic warming and suggesting that the EAIS contribution to future global sea-level projections may be under-estimated.

TL;DR: In this article, a study from the Bransfield Basin that extends through the Holocene, recording the variable climate history back to the decoupling of the ice sheet from the continental shelf ~10 650 calendar years before present, is presented.

TL;DR: In this article, the authors explore the nature of a sedimentary succession in a deep tectonic trough identified as a prime candidate for a large subglacial paleolake.
