2014 and 2016 time series of automatic weather station (AWS) data (Dataset 1) and (ii) GPS data (Dataset 2) at the location of the SAFIRE research project, Store Glacier, Greenland.

These files contain ground penetrating radar (GPR) data collected from the glacier margins and forelands of Falljökull and of Kvíárjökull, south-east Iceland, between 2012 and 2014. The data were collected using a Sensors and Software PulseEKKO Pro GPR system. For each glacier the data are stored in folders that indicate the month and year in which the surveys were conducted. Each GPR profile has a Sensors and Software GPR (.DT1) file, and associated header (.HD) and GPS (.GPS) files. The .HD files (which can be opened as text files) give the parameters and equipment used for each profile. GPS files are not available for some of the profiles collected on Falljökull in April 2013 (due to damage that occurred to the GPS linked with the PulseEKKO Pro system). For these profiles start, finish, and mid profile positions were recorded using differential GPS, and locations of these profiles are instead given by GIS shapefiles in the relevant folders. These datasets have been used in the publications listed below. Further information relating to the data collection methodology can be found therein.

These high resolution high-oblique time-lapse images were collected in hourly intervals from 5 locations around Helheim glacier in SE Greenland in the summer of 2013. Three cameras (Cameras 1, 2 and 3) were aimed at the calving front ~3.5 km down glacier from the calving front and two cameras (Cameras 4 and 5) were aimed cross-glacier ~3 km up glacier from the calving front. The images are in two stereo groups allowing the extraction of 3D data with significant processing though there are some optical issues that will degrade quality.

These data consist of a spreadsheet containing 557 ground control points (GCPs) collected in the Everest region of Nepal between October 2015 and October 2016. GCPs were collected using a Leica GS10 differential Global Positioning System (dGPS), post-processed against base station data at Syangboche. These final data have sub-centimetre accuracy (in x, y and z) in all cases. Point positions are heavily concentrated around meltwater ponds on the glacier surface, and prominent features around the glacier margin. These data will be used by PhD students and staff in the School of Geography, University of Leeds, to provide ground control for fine-resolution satellite imagery and Structure-from-Motion surveys to assess mass loss processes on Khumbu Glacier.

2014 and 2016 time series of basal multiprobe data (Dataset 1), englacial temperature data (Dataset 2), and englacial tilt data (Dataset 3) measured in boreholes drilled at the location of the SAFIRE research project, Store Glacier, Greenland.

There is a report highlighting the approach for model construction and recommendations for any future work. There is an excel file pf processed data including time, centrifuge speed, water pressure, and temperature data. There is a zip folder containing photographs of the models, the instrumentaiton and granular ice used for model construction There is a zip folder containing the raw data.

Groundwater level and groundwater temperature data measured in 9 boreholes between August 2012 and August 2018. Groundwater conductivity data measured in 1 of these boreholes from September 2012 to August 2014. Eight of the boreholes are drilled into a sandur (glacial outwash floodplain) aquifer in front of Virkisjokull glacier, SE Iceland, and are between 8.2 and 14.9 m deep. The remaining borehole is drilled into a volcanic rock aquifer between the sandur and glacier and is 5.1 m deep. Selected groundwater monitoring data are reported in Ó Dochartaigh, B. É., et al. 2019. Groundwater?- glacier?meltwater interaction in proglacial aquifers, Hydrol. Earth Syst. Sci. https://doi.org/10.5194/hess-2019-120.
