2 Study Area and Measurement Techniques
The Isvika Bay (80
N18
40
0
E) is located inside Murchisonfjorden in the
Vestfonna of Nordaustlandet, which is the northeastern island of the Svalbard
archipelago (see Fig.
1
). The analyzed bay was formed by ice-flow patterns three
times in the past and now is under the influence of glacial rivers and marine
sedimentation. The data used in this study were collected during the expeditions
of PPE and the IPY Kinnvika project in summer 2009. Measurements were done
with multibeam sonar “Sea Beam 1180” mounted on board of a research vessel
Horyzont II. The vessel position and the sound velocity in water were taken into
account during the analysis. Preliminary data analysis consisted of calculating the
depth on the 1-m grid size. Ordinary Kriging interpolation method was used to
supplement the lacking data. Processed data were used for further statistical
investigation.
