This dataset consists of long time series of subglacial water pressures, obtained from a pressure sensor installed in a borehole that connected to the basal drainage system of Kongsvegen, Svalbard. The glacier has been in a quiescent state since its last surge circa 1948, and has undergone a gradual acceleration during the last decade. The data series runs from 2018-10-19 to 2024-08-12. Data acquisition was funded by NERC Urgency Grant NE/R018243/1 REBUS (Resolving Enthalpy Budget to Understand Surges) and RCN Grant 301837 MAMMAMIA (Multi-scale, multi-method assessment of mechanisms for ice acceleration).

This dataset consists of a bed DEM and four velocity maps of Kongsvegen, a surge-type glacier in Svalbard. The bed DEM was generated from ground-penetrating radar surveys in spring 2016 and 2018, and the velocity maps span the period Dec 2017 to Feb 2019. The velocity maps show the initial speed-up of the glacier as it transitions from quiescence to surge. Data acquisition was funded by NERC Urgency Grant NE/R018243/1 REBUS (Resolving Enthalpy Budget to Understand Surges).
