Cosmogenic Be-10 data and calculated surface exposure ages from nunataks adjacent to Pine Island Glacier in the Hudson Mountains, West Antarctica

This dataset consists of measurements of cosmogenic 10Be in quartz from a set of erratic cobbles collected from the surfaces of nunataks in West Antarctica. The cobbles were collected during the 2019-20 Antarctic field season from the Hudson Mountains, which are situated adjacent to Pine Island Glacier. The dataset includes cosmogenic nuclide (10Be) exposure ages and all field (sample locations and elevations) and analytical laboratory (quartz and beryllium carrier masses, Be-10/Be-9 ratios) data for field samples and procedural blanks required to calculate the ages.

Natural Environment Research Council (NERC: Grants NE/S006710/1, NE/S006753/1, and NE/S00663X/1) and National Science Foundation (NSF: Grant OPP 2317097). Australian Nuclear Science and Technology Organisation (ANSTO) Centre for Accelerator Science award AP12872, through the National Collaborative Research Infrastructure Strategy (NCRIS).

Statement
Quartz purity was tested using inductively coupled plasma optical emission spectrometry (ICP-OES). For isotope dilution chemistry, a procedural blank (beryllium carrier processed with no quartz) was processed for every 11 samples, resulting in 13 total procedural blanks. This dataset of blank measurements includes those from batches of other samples processed during the same few months as those in this study. We also processed two replicate measurements and one aliquot of the laboratory intercomparison material CRONUS A. In the file titled ''Analytical data and exposure ages'', there is no value in the column titled ''Mass carrier (g)'' for sample EVK-102 (BAS ID R19.4.2). This is because EVK-102 contains native Be, so the total Be (in mg) was quantified using ICP-OES analysis.
