Description:
Abstract:
Ocean Mapping Group binary format data generated from the 2011 multibeam sonar survey on the 2011 CCGS Amundsen ArcticNet Cruise. The data include high-resolution bathymetry, acoustic backscatter and watercolumn backscatter.
Purpose:
Multibeam Surveys were carried out as part of the Ocean Mapping Group's role in the ArcticNet program.

Process_Description:
Multibeam bathymetry, watercolumn and backscatter data were collected using a Kongsberg Simrad EM3002 multibeam sonar system. Standard collection settings used auto depth mode, angular coverage of +/- 65 degrees and highdensity equidistant beamforming. SIS was used to collect the data, while daily 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 Coda Octopus F185. RTG GPS data from a CNav 2000 GPS was used to correct and improve the position output from the F185. Soundspeed information was from YSI CastAway CTD casts. F185 Firmware Version:, Software Version:, SIS Version:,; EM3002 PU Version:, CNav Unit: 2000, WaterColumn Settings: x_log_offset = 20

Process_Step:
Process_Description:
- Multibeam Data was converted from the Kongsberg binary format to the Ocean Mapping Group binary format. - Primary navigation was set as the F185 output position.- The Attitude information was merged with the sounding data.- The Navigation data was merged with the sounding data- Tides were applied using predicted tides from the Arctic9 tide model data. Depths are referenced to MSL.- Backscatter data was generated- Watercolumn data was extracted from the Kongsberg binary wcd format

Process_Step:
Process_Description:
- The sounding data was inspected for errors in Sound Velocity using the soundscape software package.- The data was checked for integrity to ensure that previous processing steps were not missed.- The bathymetry and backscatter data was gridded into our 15'x30' basemap series. (<http://www.omg.unb.ca/Projects/Arctic/basemaps/index.html>)- The bathymetry and backscatter basemap tiles were used to generate the google map tiles.
