TL;DR: Particle size and provenance signature of glacial till from the Lonewolf Nunataks at the head of Byrd Glacier, Antarctica, show evidence of subglacial origin and therefore provide new information about ice-covered bedrock of East Antarctica.

TL;DR: In this paper, the authors reported newly acquired high resolution physical properties data and the first accurate age constraints for the seismic sequences of the upper sedimentary record of the Scotia Sea to the late Miocene.

TL;DR: In this article, the La Negra volcano of Northern Chile has been used for the measurement of the true polar wander (TPW) of the Earth's crust, which is the reorientation of the crust-mantle system driven by the redistribution of masses in the mantle and on the Earth surface.

TL;DR: In this paper, the authors demonstrate that a shift in iceberg trajectories during glacial periods can result in a considerable redistribution of freshwater in the Southern Ocean, in concert with increased sea-ice cover, enabled positive buoyancy anomalies to "escape" into the upper limb of the AMOC, providing a teleconnection between surface Southern Ocean conditions and the formation of NADW.

TL;DR: In this paper, the authors explore the relationship between lower terrigenous 87Sr/86Sr and lighter benthic δ13C foraminifera at orbital frequencies and within periods of rapid variability.
