Surface exposure dating using cosmic-ray-produced nuclides has been applied to
determine the age of thousands of landforms produced by alpine glaciers in mountain areas …

Cosmogenic-nuclide concentrations in subglacial bedrock cores show that the West
Antarctic Ice Sheet (WAIS) at a site between Thwaites and Pope Glaciers was at least 35 m …

We describe new Last Glacial Maximum (LGM) ice thickness constraints for three locations
spanning the Weddell Sea Embayment (WSE) of Antarctica. Samples collected from the …

Abstract Since the Last Glacial Maximum∼ 20,000 years ago, the Antarctic Ice Sheet has
undergone extensive changes, resulting in a much smaller present‐day configuration …

Froth flotation is a commonly used procedure for separating feldspars and micas from quartz
for the preparation of quartz mineral separates to carry out cosmogenic nuclide analysis …

We present a database of observational constraints on past Antarctic ice sheet changes
during the last glacial cycle intended to consolidate the observations that represent our …

Reconstructions of past glacier extent and timing afford perspective on the efficacy of
mechanisms thought to control ice-sheet fluctuations. Here, we present data concerning the …

The effect of post-depositional processing on the preservation of snow nitrate isotopes at
Summit, Greenland, remains a subject of debate and is relevant to the quantitative …

Cosmogenic-nuclide surface exposure ages provide empirical data for testing the accuracy
of models simulating the timing and pace of ice sheet response to a warming climate …

Cosmogenic nuclide measurements in glacial deposits extend our knowledge of glacier
chronologies beyond the observational record. The short half-life of in situ cosmogenic 14C …
