Ocean Mapping Services
Integrated ocean mapping encompasses multiple facets of the marine environment including the physical (high resolution bathymetry), biological, geological, chemical and archaeological to comprehensively characterise the marine environment. Integrated ocean mapping data satisfies the critical need for:
- Detailed charts allowing safe navigation
- General science data
- Marine management policy
- Baseline data for future marine management needs
Comprehensive integrated ocean mapping vessels commonly consist of sonar technology for bathymetry and benthic habitat characterisation, mid-water multibeam for pelagic resource mapping, and low frequency towed source survey for geological mapping.
Using the latest industry technology, our ocean mapping service capabilities are extensive. Seaforth provides the following general ocean mapping services:
- Hydrographic & oceanographic surveys
- Harbour development
- Navigational hazard surveys
- UXO surveys
- Coastal and benthic and habitat mapping
Ocean Mapping Projects:
Multibeam Survey of the Laurentian Channel & St. Anns Bank
Project date: April, 2012
Seaforth conducted a multibeam survey of an area of interest (AOI) within the Laurentian Channel, part of the larger Placentia Bay-Grand Banks Large Ocean Management Area (LOMA). Within the LOMA the Laurentian Channel Ecologically & Biologically Significant Area (EBSA) has been selected as an AOI for the potential establishment of a new Oceans Act Marine Protected Area (MPA). Knowledge of the seafloor diversity through acquisition of multibeam bathymetry, backscatter and subbottom profiler data will provide the baseline data required prior to ground-truthing/bottom sampling. Accurate data on seafloor diversity will aid in understanding the ecosystem, assist in boundary delineation of the MPA and provide a baseline to assess changes to species and benthic habitat in the MPA over time.
Petitcodiac River, Bay of Fundy, NS: Petitcodiac River Monitoring Program
Seaforth has provided and continues provide a multibeam echosounder, sediment grab and water collection survey as part of a on-going sediment monitoring program. The monitoring program provides data on sediment transportation and seabed mapping to evaluate environmental impacts following the re-opening of the Petitcodiac River causeway.
Vancouver, BC: Underwater Unexploded Ordnance (UXO) Survey, Department of National Defense
Project date: January 2006
Seaforth provided seabed mapping and sampling services for the location and identification of unexploded ordinance (UXO) at several former test ranges and dump sites around Vancouver Island on behalf of the Department of National Defence.
Cohasset-Panuke, NS: Field Decommissioning Survey
Seaforth was contracted by EnCana Corporation to perform a subsea survey of EnCana’s Cohasset-Panuke (COPAN) facilities. These facilities included the Cohasset and Panuke platforms, subsea flow lines, power cables, pipeline end manifolds and telecommunications cables near Sable Island. Services provided included ROV video and TSS depth of burial surveys, multibeam and sidescan sonar surveys.
