Revision of depth contours and stratification of the West Greenland Bottom Trawl survey for Northern shrimp. Technical Report No. 56

Reliable information on the bathymetry of the West Greenland shelf has been missing for 
a substantial part covered regularly by surveys conducted by the Greenland Institute of 
Natural Resources. Therefore, depth data recorded at trawls stations and along cruise 
tracks during surveys with RV Paamiut have been compiled. Additionally, depth 
information derived from satellite altimetry has been included in the analysis. 
Geostatistical tools were used to provide depth contours for a revision of the stratification 
applied in the West Greenland Bottom Trawl Survey for northern shrimp. The study area 
covered West Greenland offshore waters between 59 and 73°N and the inshore waters in 
the Disko Bay /Vaigat area.
