These kind of glaciers play an important role in global sea level rise by production of icebergs. Precise studies of glacier flow and simultaneously the ice-cliff position changes are necessary for calculation of calving flux (volume of iceberg production). Survey of glacier flow velocity close to its end is difficult and very laborious by classical photogrammetric methods. Acquisition of airborne and satellite images in polar regions are strongly weather depend and accuracy of results are not satisfactory when the feature tracking or even the time parallax methods are used (if applicable). That why terrestrial laser scanning survey method was used to obtain high accuracy survey of glacier flow velocity, the calving flux and the range of the glacier front. This technology give us opportunity to acquisition data from the range up to 6 km with high resolution and without need to place additional marks on the glacier surface. That method is very profitable for tidewater glaciers which are one of the most difficult objects for precise monitoring of processes on their calving fronts. Up to now the research of glaciers dynamic were obtain by classical survey methods (tachymetry, GPS and terrestrial photogrammetry). Terrestrial laser scanning used for medium size grounded tidewater glacier in Svalbard seems to be an ideal tool for short period and inter annual monitoring of dynamic processes on its frontal zone. Repeated terrestrial laser scanning enable to obtain high accuracy data on change of position of particular features on glacier surface (usually crevasses) for calculation of glacier surface velocity field. Having the same data with an interval of e.g. two weeks it is possible to calculate tension rate in the badly crevassed area very close to the frontal ice cliff (not accessible for precise GPS survey). Tension rate is important for studies of mechanism of calving processes. Repeated scanning of the ice cliff is giving precise data on front position changes with a chance for distinguishing the most active parts in ice berg production. The paper describe methodology of survey of dynamics of frontal zone of glacier by using terrestrial laser scanning technology. Long range scanner Riegl LPM-321 were used and two series of scanner registration were conduct: one year period for surface and two weeks period for front during summer glacier activity. These data give us homogeneous distribution of laser points representing glacier surface. The results and analyses of that measurements will allow to assess the usefulness of chosen survey method.

The aim of the surveys was assess radar as a method for determining the size and shape of the channel system and its fill, and to map inaccessible parts of the channel system. It is possible to descend into the main channels of the system from moulins along its course and a detailed map of the accessible regions has been made. This mapping allows ground-truthing of the radar interpretation. The channel system consists of multiple channels at different elevations. The channels generally have low gradient sections linked by near vertical shafts. In common with other channels in Svalbard glaciers, the channels probably initiated as a supraglacial features progressively downcutting into the ice and filling with compressed snow from above. We show that ground-penetrating radar can be successfully used to determine the depth, shape, and water content of englacial channels because of the strong contrast in electrical properties between water, ice, and air. This technique has exciting possibilities for the remote monitoring of inaccessible englacial channels. Members of the Polish Station at Hornsund are thanked for their hospitality and logistic support.

In 1988, the first expedition involving students was organized. The next one occurred almost 15 years later, as late as 2003, thanks to the initiative of the National Club of Polish Geodesy Students affiliated with the Association of Polish Surveyors (SGP). In 1988, a control network was established around the Hornsund Fiord , consisting of 7 points placed along both sides of the fiord. During the last expeditions (2003, 2005 and 2006) measurements were repeated using GPS technology. The main task of our polar expeditions to Spitsbergen was to carry out geodetic research, the aim of which was to define the character of the Hans Glacier movements. To monitor the behavior of tanks foundations of the fuel station located in permafrost an appropriate control network was set up.
