Multibeam Sonar Data collected from the CCGS Amundsen (2003-2016)

Accoustic data was generated from the multibeam Kongsberg Simrad EM300 (2003-2008) and EM302 (2008-2016) multibeam sonar system onboard the CCGS Amundsen during ArcticNet Cruises. This bathymetric data subset covers the Canadian Arctic and includes all CCGS Amundsen's data. The datasets consist of high-resolution bathymetry and acoustic backscatter imagery collected 24 hours a day, whenever the ship was in transit or had dedicated survey time.


Standard collection settings used dual-ping, FM pulse, auto depth mode, angular coverage of +/- 60 degrees and high density equidistant beam forming. The SIS software was used to collect the data.


From 2003-2013, near realtime cleaning of data outliers was done using the Ocean Mapping Group's Swathed toolkit after conversion to OMG binary format. After 2014, the data cleaning was done in the CARIS HIPS&SIPS software. Data was exported in Generic Sensor Format (.gsf).


IMU data was parsed by SIS from a POSMv 320 v.4. RTG GPS data from the CNAV 3050 GNSS receiver was used to correct and improve the position output from the POSMV via a RTCM correction protocol. Soundspeed information was either from CTD Rosette casts, MVP300 data or simulated from the World Ocean Atlas 2009 database.


Data are gridded at a resolution of 10 metres. Grid files available are in binary floating point file (.flt). The grids will be available shortly on the Université Laval library's geospatial center website (www.geoindex-plus.bibl.ulaval.ca/).


Note: The OMG of University of New Brunswick were responsible for 2003-2013 data (www.omg.unb.ca/Projects). From 2014, responsibility switched to the Marine Geoscience Laboratory At Université Laval (www.lgm.ggr.ulaval.ca/index.php/projets/amundsen/).

Purpose

The bathymetric dataset is part of the core seabed mapping component of the ArcticNet Research Program : 'Mapping of Arctic Canada's Seafloor: Contributions to Global Change Science, Sustainable Resource Development, Safe Navigation of the Northwest Passage, Geohazards and Arctic Sovereignty'. Acoustic mapping of the seabed relief and shallow subsurface sediments are the prime datasets used by scientists to understand the geological processes shaping the seafloor, assess natural hazards and coastal habitats and reconstruct the history of past climatic changes. The mapping results from this project are applied to several components: 1) identifying geohazards such as submarine landslides, gassy seabeds and sea ice impacts in order to manage risk to both people and the environment in the context of resource development; 2) providing improved navigational charting and alternate shipping lanes in sparsely mapped regions of the Arctic; and 3) designing seabed sampling strategies to recover sediments that will provide information on past climatic history in order to predict future climatic responses and their consequences.
