ABSTRACT:

This includes the data for water level, salt dilution measurements and manual streamflow survey performed at the Peyto Glacier for 2017-20219, and the calculated streamflow for 2013-2020.

ABSTRACT:

This dataset contains time-lapse imagery of the Athabasca glacier, in the Canadian Rockies, for the 2015-2020 melt season (Jul. 1st-Sep 15). The time-lapse camera recorded pictures at 8:00, 13:00 and 16:00 local time. The meteorological observations from the on-ice weather station (52.19182, -117.25165) for the 2015-2020 period, as well as precipitation, corrected for undercatch, from the off-ice station (52.215362, -117.226359), are also shared.

ABSTRACT:

The ice-cored lateral moraine of the Peyto Glacier (51.676°, -116.554°), a well-studied outlet glacier of the Wapta Icefield in the Canadian Rockies, was selected to investigate the relationship between debris surface temperature and debris thickness. Two thermal infrared imaging radiometers were used at four locations to survey the study slope and surroundings. A Jenoptik VarioCam HD thermal infrared imaging radiometer was installed on the glacier facing the study slope at location TIR1, and recorded images at 5-minute intervals from August 5th, 2019, 17:15 to August 9th, 9:00 for a total of 1077 images over 90 consecutive hours. A second Jenoptik VarioCam Basic thermal imaging radiometer was installed at three locations for intermittent measurements during the experiment.

This resource is linked to the manuscript: Aubry-Wake, C., Lamontagne-Halle, P., Baraer, M., McKenzie, JM., Pomeroy, J. (submitted). Using ground-based thermal imagery to estimate debris thickness over glacial ice: fieldwork considerations to improve effectiveness.
It is composed of four datasets:
1) Coordinates: the location of the thermal infrared camera during the experiment, of the manual excavations and and of the ground-control points.
2) Excavations: the depth of the measured debris-thickness at 45 points
3) MET: the meteorological observations for the duration of the experiment
4) TIR: the thermal infrared images collected during the experiment, both an raw .irb format, .asci format and .png images.

This resource will be made public/published upon the acceptance of the corresponding manuscript.
