Acoustic data was generated from the multibeam Kongsberg Simrad EM300 and EM302 multibeam sonar system on the CCGS Amundsen. This bathymetric data subset covers the Greenlandic Economic Exclusive Zone (EEZ), i.e. outside of the 12 nm territorial sea extent and within the 200 nm EZZ, from 2003 to 2014. The datasets consist of high-resolution bathymetry and acoustic backscatter imagery collected 24 hours a day, whenever the ship was in transit or had dedicated survey time. Standard collection settings used dual-ping, FM pulse, auto depth mode, angular coverage of +/- 60 degrees and high density equidistant beamforming. The SIS software was used to collect the data, while near real-time cleaning of data outliers was done using the Caris HIPS&SIPS software after conversion to Generic Sensor Format (GSF) for input into MB-System database manager. Inertial Measurement Unit (IMU) data was parsed by SIS from a POSMv 320 v.4. RTG GPS data from the CNav 3050 GPS was used to correct and improve the position output from the POSMv with RTCM correction. Soundspeed information was either from CTD Rosette casts, MVP300 data or simulated from the World Ocean Atlas 2009 database. The resolution of data is 10 metres. Available tiles are in ESRI grid format (.asc). The OMG of University of New Brunswick were responsible for 2003-2013 data (http://www.omg.unb.ca/Projects). From 2014, responsibility switched to the Marine Geomorphology Laboratory of Laval University. This bathymetric data collection is part of the core seabed-mapping project within the ArcticNet research program. In this project, underway acoustic mapping of the seabed relief, sediment distribution and shallow subsurface sediments are the prime datasets used by researchers to understand the geological processes shaping the seafloor, to assess natural hazards and coastal habitats and to reconstruct the history of past climatic changes.

The Marine Geomorphology Laboratory (LGM) works at providing different other products derived from the EM302 multibeam sonar (backscatter, bathymetry in various other format, etc. These data will be distributed from a specialized data base and distribution platform when available.
