Thermistor chain measurements from West Lake Bonney, McMurdo Dry Valleys, Antarctica (2014-2019)

To capture year-round temperature variability in West Lake Bonney (WLB), Taylor Valley, Antarctica, we deployed two self-logging RBR Concerto T10 thermistor strings as part of the McMurdo Dry Valleys Long Term Ecological Research (MCM LTER) project. The thermistor strings were deployed beneath the permanent ice cover from December 2014 to November 2015 at two locations on the western side of the lake. In November 2015, both strings were relocated toward the centre of the glacier terminus to better capture potential subglacial inflows. Each thermistor string contained 10 sensors spaced at 1.44 m intervals. This data package includes 1-minute interval temperature measurements from all four deployment sites, along with daily averages compiled in a single file. Data from three thermistors were flagged as questionable based on comparisons with long-term MCM LTER CTD casts; these values remain in the dataset but are flagged to allow for adjustment during data processing.
