Abstract:
Ocean Mapping Group binary format data generated from the 2013 multibeam sonar survey on the 2013 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.

Attribute_Accuracy:
Attribute_Accuracy_Report:
All sounding data was inspected in real-time and in post-processing and then all overlapping data was checked to ensure reliability.
Logical_Consistency_Report: NULL
Completeness_Report:
Data is collected 24 hours a day during the entire cruise. Data gaps may exist when the ship was on station as data is only collected while the ship is moving.

Process_Description:
Multibeam bathymetry, watercolumn and backscatter data were collected using a Kongsberg Simrad EM302 multibeam sonar system. Standard collection settings used dual-ping, FM pulse, auto depth mode, angular coverage of +/- 60 degrees and highdensity 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 Rossette casts, MVP300 data or by J. Beaudoin's SVP Editor v1.0.5 for the delivery of synthetic sound speed profiles directly to SIS using the World Ocean Atlas 2009 database and National Weather Service Real-Time Ocean Forecast System.POSMv Firmware Version: 4SIS Version: 3.8.3, Build 89, DBVersion 19.0; -Temporarily upgraded to version 3.9.2, Build: 187, DBVersion 20.0; Installed July, 2013 before rolling back to 3.8.3 on Aug. 25 due to PC Hardware issues.EM302 PU Version:CNav Unit: 2000WaterColumn Settings: x_log_offset = 20

Process_Description:
- 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 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/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.
