Abstract We present a study of the development thermo-erosional notch at waterline and its influence on calving Hansbreen, medium-sized grounded tidewater glacier in southern Svalbard. The is based results undercut melt modelling, measurements sea-water properties, repeated terrestrial laser scans analysis time-lapse camera images. There strong correlation between observed activity modelled rate notch. Measured depths reach 4 m vary greatly over time. Hansbreen was significantly lower 2011...
Abstract The mechanism of glacier recession and its climatic controls are complex processes that differ across the Arctic region. Here, we investigate factors influencing front variations Hansbreen, a terminated in Hornsund fjord (SW Svalbard). We apply remote sensing data to observe fluctuations between 1992 2015 compare them atmospheric oceanographic data, sea water depth at terminus surface velocity. Rate subglacial meltwater discharge approximated by seasonal positive degree‐day index...
Environment of the Atlantic sector Arctic, where Svalbard ice masses lie, is highly vulnerable to climate changes. Mass balance a few selected glaciers are well known from field measurements, however it's also important calculate changes in glacier volume archived data and remote sensing methods for with no direct measurements. Rapid topography cause need eliminate uncertainties re-analyse mass calculations. In this study, based on digital elevation models photogrammetric photos satellite...
Abstract We describe the annual pattern of frontal ablation driven by submarine melting mechanisms at Hansbreen terminus: these are reflected in intensity and spatial distribution calving events. Analysis time-lapse images front conjunction with oceanographic meteorological data shows that is primarily seawater temperature. Regression analysis also highlights importance air temperature, which we take to be a proxy for surface subglacial discharge. This, combined seasonal changes ice cliff...
Abstract. Climate shifts are particularly conspicuous in the Arctic. Satellite and terrestrial observations show significant increases melting breakup of Arctic tidewater glaciers their influence on sea level rise. Increasing melt rates creating an urgency to better understand link between atmospheric oceanic conditions glacier frontal ablation through iceberg calving melting. Elucidating this requires a combination short long-time scale measurements terminus activity. Recent work has...

Polar regions are extremely sensitive to pollution such as harmful gases, particles or toxic substances which affect the Arctic climate and ecosystems. Spitsbergen, well all region, because of its geographically distant location lack industry sector, should be free chemical pollution. Despite this, many pollutants could found in environment, for example freshwaters. Their occurrence is related with global distillation process (Grasshopper effect) contaminants from lower latitudes transferred...
This study presents the results of a 5-year monitoring program ice cover, water temperature, and local meteorological conditions carried out in three reference lakes periglacial zone Polish Tatra Mountains. On basis this information, relationships between weighted mean temperature each these air wind speed, precipitation, ice–snow cover summer, spring, autumn seasons, as well year-round, were described, roles morphometry topography their catchments determined. It was found that sensitivity...
