Accoustic data was generated from the multibeam Kongsberg Simrad EM302 multibeam sonar system onboard the CCGS Amundsen during ArcticNet Cruises. This bathymetric data subset covers the Greenland Economic Exclusive Zone (EEZ), i.e. outside of the 12 nm territorial sea extent and within the 200 nm EZZ, from 2005 to 2011 and 2013. 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. SIS was used to collect the data, while near realtime cleaning of data outliers was done using the Ocean Mapping Group's Swathed toolkit after conversion to OMG binary format. IMU data was parsed by the SIS software from a POSMv 320 v.4. RTG GPS data from the CNav GPS was used to correct and improve the position output from the POSMv. Soundspeed information was either from CTD Rosette casts, MVP300 data or simulated from the World Ocean Atlas 2001 database. Data were gridded at a resolution of 10 metres. Grid files available are in ESRI grid format (.flt and .hdr files zipped for each mapsheet for the data from 2005 to 2011, and .asc files for the data of 2013). Futher information on data processing and on the Ocean Mapping Group activities are online at http://www.omg.unb.ca/Projects/Arctic/ 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.
