Implications for gas hydrate occurrence : 3D thermobaric modelling of central Spitsbergen
… in the first assessment of the GHSZ for central Spitsbergen. The framework's Python back-end allows for both laterally and vertically changing input parameters, is easily upgradable with both new functions and novel datasets, and provides a link to third-party tools while guaranteeing …

Comparative aerosol studies based on multi-wavelength Raman LIDAR at Ny-Ålesund, Spitsbergen
… of aerosol layers above Ny-Ålesund, Spitsbergen. The attention was turned to the analysis of periods with high aerosol load. As the Arctic spring troposphere exhibits maximum aerosol optical depths (AODs) each year, March and April of both the years 2007 and 2009 were analyzed. …

Modelling the future mass balance of glaciated Northwest Spitsbergen, Svalbard for a range of socio-economic trajectories
Spitsbergen, Svalbard, is covered by approximately 22,000 km2 of glaciers, which are particularly sensitive to the enhanced global warming expected over the region (Nuth et al., 2010; Miao et al., 2014). Loss of these glaciers has global, regional and local implications. The study transiently …

Radio Echo Sounding Studies of Svalbard Glaciers
… made on the dielectric properties of a sample of Spitsbergen ice. Data were collected between 20 Hz and 100 kHz in the temperature range -2.5 to -44.0C . From these and other data deductions about the thermal regime of the ice masses were made and a geographical trend, linked to the reflection …

The effectiveness of spaceborne synthetic aperture radar for glacier monitoring
… C-band SAR dataset of Nordenskiold Land, Spitsbergen, acquired by the ERS-1 satellite, is used for the analysis, which focuses on mountain glaciers rather than ice sheets. Validating field measurements of ice and snowpack parameters were obtained contemporaneously with two SAR images, …

Landslide generated tsunamis : numerical modeling and real-time prediction
… The current geological situation west of Spitsbergen is comparable to the continental margin off Norway after the last glaciation, when the large tsunamigenic Storegga slide took place. The influence of Arctic warming on the stability of the Svalbard glacial margin is discussed. Based on …

Remote Sensing Studies of Svalbard Glaciers
… point was tested over a number of glaciers in Spitsbergen. Ice thickness data were obtained from 38 glaciers. The results are compared with previous geophysical investigations of ice thickness on Spitsbergen, revealing problems concerning existing Soviet radio echo sounding data obtained at …

Mixing and circulation of meltwater outflow plumes in polar fjords
… was undertaken in a fjord on the west coast of Spitsbergen, Svalbard to verify the results and characteristics of the meltwater plume of the numerical model developed. The data showed the fjord to agree well with previous work carried out in fjords with glaciers at their heads. Using a simple …

Stratigraphic and Geochemical Expression of Early Cretaceous Environmental Change in Arctic Svalbard
… of Svalbard. The “outsized clasts” recorded on Spitsbergen do not show evidence that they were rafted by glacial ice (e.g. surface striations), although could have been rafted by seasonal sea-ice. The results show that regionally widespread cold water conditions were the most likely control on …

Investigation of tropospheric arctic aerosol and mixed-phase clouds using airborne lidar technique
… 2004 and SVALEX 2005, performed in vicinity of Spitsbergen in the Arctic. The novel evaluation schemes, the Two-Stream Inversion and the Iterative Airborne Inversion, were applied to the obtained lidar data. Thereby, calculation of the particle extinction and backscatter coefficient profiles …

The Mass balance modelling of Spitzbergen glaciers
… carried out on two glaciers in north-west Spitsbergen, Midre Lovenbreen and Austre Broggerbreen, using an energy balance model. A general description of glaciers, including their classification and the manner in which their surfaces may be sub-divided, is carried out. A discussion is then …

Investigation of Surge-Type Glaciers in Svalbard
… Bjuvbreen, a small surge-type glacier in central Spitsbergen, to determine the dynamics and hydrology of the glacier during its quiescent phase. The probability that a glacier in the Svalbard sample population was surge-type was 36·4%. The probability varied spatially within the sample area. …

A Glacial Sedimentary System in Northwest Spitzbergen
… change in Signedalen and Krossfjorden, northwest Spitsbergen, since the Late Weichselian glacial maximum, has been constructed using an integrated analysis of lacustrine, terrestrial and marine sediments. Thirty-four piston cores were taken from two series of linked lakes in Signedalen, fed by …
