Changes in position of glacier front are obtained from a Riegl FG21-LR laser distance ranger (the temporal resolution of 10 minutes) taken during September 2009 – February 2013. The database is the supplement to the paper: Małgorzata Błaszczyk, Jacek A.

Meteorological data from Flat Glacier (Flatbreen) - air temperature.

Air temperature is provided by AWS 4 (N77°02' E15°38', 183 m). Air temperature comes from a Campbell Scientific 107 sensor at +/- 0.1° C resolution and sampled every 10 minutes, averaged to daily resolution in post-processing.

A snowpit analysis template developed during Hansbreen Snowpit Database preparation. Relying on the enclosed files will enable the efficient use of the Interactive Snow Profile Visualizer niViz software (https://niviz.org) and achieve interoperable final products. ZIP catalogue contains the following filenames extensions: A) PDF – used to print table template on a waterproof paper (A4 or A5 format) and provide collecting the complete range of data during fieldwork; B) XLS – used for data archiving. Contained formulas automatically calculate the thickness and water equivalent of subsequent snow layers. All information regarding the snow data harmonization on Hansbreen is available in the journal article: Laska M., Luks B., Kępski D., Gądek B., Głowacki P., Puczko D., Migała K., Nawrot A., Pętlicki M.

Hansbreen velocity is measured with a Global Navigation Satellite Systems (GNSS) receiver that sampled location every 3 hours at stake 4MONIT located approximately 3.5 km upstream of the glacier terminus (N77°02’ E15°28’). Monitoring of the glacier is conducted by Institute of Geophysics Polish Academy of Science. We calculate the daily speed based on each midnight positions (with a horizontal accuracy of ±4 cm).

The orthophotomap was prepared on the basis of infrared aerial photographs taken by EUROSENSE in September 1998. The study covers the Dolina Kiezmarskej Bieley vody valley located in the High Tatra Mountains (Slovakia). Cartographic projection: Universal Transverse Mercator, Ellipsoid: WGS 84, Coordinates system: UTM zone 34. The project was financed by No.3P04E 045 23. Editors: Bogdan Gądek, Milan Koren (sen.), Milan Koren (jun.) The project was financed by the Polish Commitee on Scientific Research under term of research grant No. 3P04E 045 23.

Inventory of tidewater and landbased glaciers delineated from archival satellite images (ASTER, Landsat) for Southern Spitsbergen. Tidewater glaciers are delineated based on satellite data from 2010. Landbased glacier are extracted from different satellite data (2005-2010). Shapefiles have basic information in the attribute table (name, ID, area, type of glaciers). Detailed description of the source data and accuracy data for glaciers from hydrological basin of Hornsund can be found in: Błaszczyk M., Jania J.A., Kolondra L., 2013: Fluctuations of tidewater glaciers in Hornsund Fiord (Southern Svalbard) since the beginning of the 20th century. Polish Polar Research, 34( 4): 327-352.http://journals.pan.pl/dlibra/publication/114504/edition/99557/content

Hansbreen velocity along the center line (stakes 2 to 11) is measured with a Global Navigation Satellite Systems (GNSS) receiver and were manually recorded weekly for stakes 2 through 5, and monthly for stakes 6 through 11, dependent on weather conditions. Monitoring of the glacier is conducted by Institute of Geophysics Polish Academy of Science. The minimum observation times at those stakes is between 20 and 30 minutes. Total error, taking into account GNSS receiver, stake tilt, and human factor is estimated at 20 cm.

Dataset contains location of glacial shafts (moulins) on two polythermal glaciers: Werenskioldbreen and Hansbreen. Fieldwork has been done with GPS device at the end of ablation season in 2015.

The base contain: 1. List (*xls) of terrophotogrammetric photographs taken by member of Polish Expedition on Iceland in 1968 (zone of Skeidarárjökull). 2. Skaning above photographs with resolution of 2400 dpi, file format *.tif and *.jpg (400 dpi). All photographs were taken by means of instrument type Phototheodolite Zeiss 19/1318 on glass plates. Authors of photographs: Tadeusz Konysz. Fot better identification of all photographs was prepared presentations (in *.pptx and *.pdf formats), where photographs there are arranged in in common practise, classic form used for terrophotogrammetric stereoscopic photographs: A, AL, AR, B, BL, BR (the meaning of a letter: A - right photogrammetric station and photograph taken in normal case [90°]; B - left photogrammetric station and photograph taken in normal case [90°]; AL - photograph taken from right station in left direction; AR - photograph taken from right station in right direction; BL - photograph taken from left station in left direction; BR - photograph taken from left station in right direction). Other photographs (e.g. panoramic) has additional informations. All names of photogrammetric stations and name of objects (in Polish language) was taken from the author’s collection of data.
