- Abstract:
-
Ocean Mapping Group binary format data generated from the 2009 multibeam sonar survey on the 2009 CCGS Nahidik GSC Cruise. The data includes 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.

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. Secondary IMU data was logged from a Seatex MRU-6 motion sensor on the EM3002 Pole. RTG GPS data from a CNav 2050 GPS was used as the primary position input for SIS. Soundspeed information was from AML SVP&T sensor.

- Process_Description:
-
- Multibeam Data was converted from the Kongsberg binary format to the Ocean Mapping Group binary format. - Primary navigation was set as the CNav 2050 output position (-0.4m ahead of EM3002 and -2.20m to starboard of EM3002).- The Attitude information was merged with the sounding data (RP set as EM3002 head). The patch test results were applied in post processing, roll: +2 degrees, pitch: +2 degrees, heading: +3.6 degrees. - The Navigation data was merged with the sounding data- Tides were applied using predicted tides from the Arctic8 tide model data. Depths are referenced to MSL.- Backscatter data was generated- Watercolumn data was extracted from the Kongsberg binary wcd format

- 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.
