Abstract. We present a 14 year record of in situ glacier surface velocities determined by repeated GNSS measurements at a dense net of 52 stakes distributed across two glaciers, Johnsons (tidewater) and Hurd (land-terminating), located on Livingston Island, South Shetland Islands, Antarctica. The measurements cover the period 2000–2013 and were done at the beginning and end of each austral summer season. A second-degree polynomial approximation is calculated for each stake, which allows estimating the approximate velocities at intermediate times. This dataset can be useful as input data to numerical models of glacier dynamics, or for calibration and validation of remotely sensed velocities such as D-inSAR or SAR offset/coherence tracking velocities, for a region where very scarce in situ glacier surface velocity measurements are available.
