“…Detailed bathymetric data reveal that the seafloor in Isvika bay has a flat central platform with steep slopes, especially on its northern side (Moskalik and Bialik 2011;Moskalik et al 2012;see Fig. 2).…”

A 2.5−metre−long marine core from Isvika bay in Nordaustlandet (80°N, 18°E) was AMS 14 C dated and analysed for its sedimentological and magnetic parameters. The studied record was found to cover the entire Holocene and indicates major turnovers in the palaeo− hydrography and sedimentary depositional history. The area was deglaciated at around 11,300 BP. The early Holocene has indications of rapid melting of glaciers and frequent depo− sition of ice−rafted debris (IRD). The climatic optimum terminated with a probable glacier re−advance event occurring ca. 5800 cal BP. This event caused the deposition of a diamicton unit in Isvika bay, followed by a shift towards a colder and a more stratified hydrographic set− ting. The reduction in IRD indicates gradual cooling, which led to the stratification of the bay and eventually to more persistent fast sea−ice conditions by 2500 cal BP. For the last 500 years, Isvika has again been seasonally open.

“…-Groups of fitting polynomial functions, inverse distance weights and kriging methods were used for interpolation bathymetry in the Brepollen area. These methods have been dis− cussed and used for interpolation of topographic and other GIS environmental data in many published works (e.g., Chaplot et al 2006;James 1996;Krivoruchko 2001;Legleiter and Kyriakidis 2008;Merwade 2009;Majdański 2012;Moskalik and Bialik 2011;Moskalik et al 2012;Schmidt et al 2003).…”

Determination of High Arctic regions bathymetry is strictly dependent from weather and ice mass quantity. Due to safety, it is often necessary to use a small boat to study fjords area, especially close to glaciers with unknown bathymetry. This precludes the use of modern multi−beam echosounders, and so traditional single−beam echosounders have been used for bathymetry profiling. Adequate interpolation techniques were determined for the most probable morphological formations in−between bathymetric profiles. Choosing the most accurate interpolation method allows for the determination of geographical regionalisation of submarine elevations of the Brepollen area (inner part of Hornsund, Spitsbergen). It has also been found that bathymetric interpolations should be performed on averaged grid values, rather than individual records. The Ordinary Kriging Method was identified as the most adequate for interpolations and was compared with multi beam scan− ning, which was possible to make due to a previously modelled single beam interpolation map. In total, eight geographical units were separated in Brepollen, based on the bathy− metry, slope and aspect maps. Presented results provide a truly new image of the area, which allow for further understanding of past and present processes in the High Arctic.

“…(2011b). Terrestrial mapping of western Nordaustlandet was published by Kolondra (2007), and bathymetric mapping of parts of Murchinson Bay by Moskalik and Bialik (2011) and how to navigate in uncharted waters (Pastusiak 2011). A vast part of the data collected during the IPY‐KINNVIKA expeditions was weather data from automatic weather stations.…”
