1. Field observations and sample information.

These spreadsheets contain information about the location and physical characteristics of all samples collected during the project. This includes data collected by handheld GPS and barometric altimeter in the field. In addition, they contain some information about which samples were prepared for later analysis, and what sample preparation steps were applied to each sample.

2. Measurements of cosmogenic He-3 in quartz.

We used measurements of cosmogenic helium-3 in quartz as a screening tool to attempt to identify samples that had been exposed for multiple glacial-interglacial cycles. This involved separating a ~150 mg aliquot of quartz by hand-picking from crushed rock, and then determining the amount of helium-3 present by heating the aliquot under vacuum and mass-spectrometrically analysing the released gases. The following spreadsheets contain helium-3 concentrations.

3. Measurements of cosmogenic Ne-21 in quartz.

We measured cosmogenic Ne-21 in some samples from the Schmidt, Williams, and Thomas Hills. Mainly these measurements were for the purposes of i) getting some idea of the age of various highly weathered surface deposits, and ii) gaining information about whether certain parts of the field area had or had not experienced long periods of ice cover in the past.

4. Measurements of cosmogenic Be-10 in quartz.

We measured cosmogenic Be-10 in quartz in a fairly small subset of the total sample set. Analyses of 27 samples collected from the Schmidt and Williams Hills in 2010-11 are complete. Analyses of samples collected from the Thomas Hills in 2011-12 are partially complete.
