Norbit - MBES In Arctic Conditions Case Study 

In the summer of 2014 the mapping of Hornsund fjord glaciers took place by Norbit and the Institute of Oceanology, Polish Academy of Sciences in Spitsbergen, the Arctic.

The purposes of the  survey were threefold:

  • test Norbit compact MBES in the difficult Arctic conditions, 
  • map tide-glaciers front walls and measure bathymetry of post-glacial bays, 
  • as well as detect tide-glaciers underwater outflows detection based on MBES water column data. 

The works were conducted in frames of the Polish-Norwegian projects 'Arctic Climate System Study of Ocean, Sea Ice and Glacier Interactions in Svalbard Area' (AWAKE2) and  'Glaciers as Arctic Ecosystem Refugia' (GLAERE) in the Polish Polar Station in Hornsbund (Svalbard). 

Using an aluminium small boat, a pole mounted Norbit integrated wideband multibeam sonar (iWBMS), pole mounted POSMV, with QINSy software (for acquisition and data processing) installed on a laptop, all powered by a compact Honda 20i generator.

The survey resulted in two of the main glaciers in Hornsund fjord being mapped; seabed bathymetry as well as underwater walls structure. Very promising results of water column data analysis were obtained for future detection of freshwater outflows from below the glacier.
