- Abstract:
-
Ocean Mapping Group binary format data generated from the 2005 multibeam sonar survey on the 2005 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 role in the ArcticNet program.

Multibeam bathymetry and backscatter data were collected using a Kongsberg Simrad EM300 multibeam sonar system. Standard collection settings used auto depth mode, angular coverage of +/- 60 degrees and 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.3. 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 Rossette casts, MVP300 data or the simulated from the World Ocean Atlas 2001 database.POSMv Firmware Version: 3SIS Version: N/AEM300 PU Version: N/ACNav Unit: 2000

- Multibeam Data was converted from the Kongsberg binary format to the Ocean Mapping Group binary format. - Primary navigation was set as the POSMv 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 Arctic8c tide model data. Depths are referenced to MSL.- Backscatter data was generated

- Process_Description:
-
- The sounding data was re-raytraced using collected CTD profiles and sound speed profiles generated from the World Ocean Atlas 2001 database. Sound Speed Processing was completed 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, backscatter and sub-bottom data was to generate the stripmap map series. (<http://www.omg.unb.ca/Projects/Arctic/stripmaps/index.html>)- The bathymetry and backscatter basemap tiles were used to generate the google map tiles.
