TL;DR: In this paper, the maximum limits of the Eurasian ice sheets during four glaciations have been reconstructed: (1) the Late Saalian (>140 ka), (2) the Early Weichselian (100-80 ka),(3) the Middle Weichsellian (60-50 ka), and (4) the late Weichselsian (25-15 ka) based on satellite data and aerial photographs combined with geological field investigations in Russia and Siberia, and with marine seismic and sediment core data.

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 1985, a Sino-Swiss limnogeological expedition to China's largest inland lake recovered seismic profiles and piston cores to help calibrate palaeoclimatic models of monsoon and insolation fluctuations over the northern Tibet-Qinghai Plateau since the Last Glacial Maximum as discussed by the authors.

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: In this paper, the authors examined geophysical data from a multi-sensor core logger (MSCL), a logging device providing continuous measurements of gamma-ray attenuation, p-wave travel time, and magnetic susceptibility on marine sediment cores.
