Obliquity-paced Pliocene West Antarctic ice sheet oscillations
Thirty years after oxygen isotope records from microfossils deposited in ocean sediments confirmed the hypothesis that variations in the Earth’s orbital geometry control the ice ages, fundamentalExpand

Antarctic records of precession-paced insolation-driven warming during early Pleistocene Marine Isotope Stage 31
Precisely dated Antarctic continental margin and Southern Ocean geological records show that the early Pleistocene interglacial Marine Isotope Stage 31 (MIS-31) was characterized by warmer thanExpand

A new method for the determination of absolute abundance of diatoms and other silt-sized sedimentary particles
The determination of absolute abundances of diatoms in paleolimnological and paleoceanographic studies is now becoming a routine step in diatom paleoecological investigations. Several distinctExpand

A ploughing model for the origin of weak tills beneath ice streams: a qualitative treatment
Abstract Glaciological studies of West Antarctic ice streams have shown that weak sub-ice-stream tills provide the basal lubrication that makes fast ice streaming possible under low driving stresses.Expand

Sedimentary processes at the base of a West Antarctic ice stream: Constraints from textural and comp
A control circuit having an adaptive turn-off feature for a vehicle skid control braking system, wherein the control circuit is responsible for producing a brake control signal which is effective toExpand

WISSARD at Subglacial Lake Whillans, West Antarctica: scientific operations and initial observations
A clean hot-water drill was used to gain access to Subglacial Lake Whillans (SLW) in late January 2013 as part of the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project. Over 3Expand

Late Paleogene diatom biostratigraphy and Paleoenvironments of the northern Norwegian-Greenland Sea
Diatom occurrence, abundance, and biostratigraphic position are documented from Paleogene sediments of Ocean Drilling Program (ODP) Leg 151 in the high-latitude Norwegian-Greenland Sea. PreviousExpand

Pleistocene variability of Antarctic Ice Sheet extent in the Ross Embayment
Cores acquired by the ANDRILL McMurdo Ice Shelf Project (AND-1B) provide the basis for a new sedimentation model for glacimarine depositional sequences that reflect cyclic glacial–interglacialExpand

Extensive retreat and re-advance of the West Antarctic Ice Sheet during the Holocene
To predict the future contributions of the Antarctic ice sheets to sea-level rise, numerical models use reconstructions of past ice-sheet retreat after the Last Glacial Maximum to tune modelExpand

Quaternary and Tertiary microfossils from beneath Ice Stream B: Evidence for a dynamic West Antarctic Ice Sheet history
Abstract Some glaciologists have suggested that the West Antarctic Ice Sheet, which is grounded well below sea level, may be susceptible to rapid grounding-line retreat and disintegration. However,Expand
