      <gmd:abstract>
        <gco:CharacterString>200+ erratic and bedrock samples were collected for cosmogenic isotope analysis, as well as several depth profiles of tills. Samples were collected from 11 sites along a 350km transect stretching from Pirrit Hills in the south to the ridge between Mt Bentley and Mt Hubley in the north. Most sites were on the western (West Antarctic Ice Sheet) side of the range but includes Flowers Hills on the east side of the range, adjacent to the Rutford Ice Stream. Throughout, the emphasis was on taking samples to allow dating of any changes in ice altitude/extent.</gco:CharacterString>

Sampling methods consisted of hammer and chisel, petrol-powered rock saw (in a few instances), and pits dug into glacial sediments.
Data quality: 
The quality of the samples is excellent as the majority of the lithologies we sampled were quartz-rich sandstones and quartzites. Initial laboratory results confirmed that these samples contain abundant material for analysis.</gco:CharacterString>
