- Abstract:
-
Ocean Mapping Group binary format data generated from the 2014 multibeam sonar survey on the 2014 M/V Nuliajuk Government of Nunavut 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 seabed mapping program funded jointly by the Government of Nunavut, Natural Resources Canada (NRCan), Canada-Nunavut Geoscience Office (CNGO) and the Ocean Mapping Group, UNB.

Multibeam bathymetry, watercolumn and backscatter data were collected using a Kongsberg Simrad EM2040C multibeam sonar system. Standard collection settings used auto depth mode, angular coverage of +/- 65 degrees, highdensity equidistant beamforming, Frequency Modulated (FM) chirp and 200 kHz or 300 kHz frequency depending on depth. 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 Coda Octopus F185+. RTG GPS data from the CNav 3050 GPS was used to correct and improve the position output from the F185+. Soundspeed information was from AML SVPlus CTD casts. F185+ Firmware Version: 131113q6.14b and Software: 3.6.0; SIS Version: 4.1.3, Build 14, DBVersion 24.0; EM2040C PU Version:2.0.4;CNav Unit: 3050;WaterColumn Settings: x_log_offset = 30;

- 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_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/SE_Baffin_basemaps/index.html>)- The bathymetry and backscatter basemap tiles were used to generate the google map tiles.
