Front velocity of tidewater glaciers in Hornsund

Glacier velocities are derived from the displacements of four stakes (Z, R, T, U) installed close to the front of three glaciers in Hornsund. Measurements of stakes position were conducted in 2013-2015, with precise dGPS receiver (Leica 1230, accuracy ±5cm) and single-frequency GPS receiver (Garmin, accuracy ±5m).

Coverage area: Hansbreen Z| POINT (77.02 15.64) Storbreen R| POINT (77.10 16.36) Hornbreen T| POINT (77.07 16.65) Hornbreen U| POINT (77.06 16.70)

Date/time range: Hansbreen Z| August 2013-August 2014 Storbreen R| August 2013- August 2014 Hornbreen T| August 2014 - August 2015 Hornbreen U| August 2014- August 2015

Data quality: Stakes positions measured with precise dGPS receiver were estimated with use the corrections from reference GPS station at the Polish Polar Station in Hornsund. Measurements with single-frequency GPS receiver were based on two minutes observations. The accuracy was sufficient for determining glaciers velocities in one-year interval.
