Post-processed and mosaicked multibeam echosounder data near Qikiqtarjuaq, NU, Canada.

10.5884/12844

Multibeam echosounder data near Qikiqtarjuaq were collected by the CCGS Amundsen in 2007 and by the RV Nuliajuk from 2012-2015. Data collected between 2007 and 2014 were processed by the Ocean Mapping Group at the University of New Brunswick (http://www.omg.unb.ca/) and were retrieved from their data sharing interface (http://www.omg.unb.ca/Projects/Arctic/SE_Baffin/). Data collected in 2015 were processed by the Fisheries and Marine Institute at Memorial University of Newfoundland (https://www.mi.mun.ca/) and were obtained directly from them. These datasets were clipped to only include the area near Qikiqtarjuaq relevant to the benthic habitat mapping project lead by the Memorial University Marine Habitat Mapping Group. Individual datasets were mosaicked to create single continuous bathymetry (m) and backscatter (dB) raster layers at 5 m resolution. Mapping activities were funded by ArcticNet and the Government of Nunavut, Department of Environment, Fisheries and Sealing Division to support benthic habitat mapping for marine ecosystem management in this area.
