McGregor Geoscience Limited has a legacy of accomplishment in the planning, management and execution of hydrographic and marine geoscience projects dating back to 1973.
Senior management at McGregor GeoScience have a combined 65 years of operational experience in the collection and interpretation of land and marine geoscience, hydrographic, environmental and precise navigation data. Our team's experience spans not only several continents and decades but has also bridged a wide range of technological developments/enhancements in the methodologies and systems employed in the execution of our work. The development and implementation of the Global Positioning System has forever changed navigation and positioning while the switch from analogue to digital has enabled us to collect and manage large volumes of data in a more flexible and efficient manner whilst enhancing data quality and resolution. These are only a few of the myriad developments and improvements we have witnessed and participated in. As the costs of conducting surveys have increased and the risks to personnel, the environment and private property have become priorities we have also become more cognizant of the need to have documented and implemented systems and procedures in place to manage safety, quality and production whilst protecting our people and the environment.
In March, 2007, McGregor GeoScience Limited was purchased by Superport Marine Services Limited of Port Hawkesbury, NS. The new ownership, while bringing an increased level of investment in the capabilities of McGregor has also provided access to a range of personnel and equipment resources that has served to expand our capabilities to our client base. McGregor can now boast access to dedicated survey vessels, the R/V Strait Signet and R/V Strait Explorer, both of which have been fitted with a number of permanent hull and deck mounted acquisition systems and have dedicated survey lab space.
The McGregor Team of geoscientists, digital engineers, hydrographers, surveyors, marine biologists, environmental scientists, GIS/CAD technicians and electronic specialists use the latest technology in data acquisition, interpretation and mapping systems to deliver comprehensive geologic and benthic reports as well as detailed bathymetric, geologic and seabed imagery charts. McGregor utilizes a suite of data acquisition tools for seabed and seafloor mapping, imaging and sampling.
Typical systems include:
96 channel, 2D high resolution seismic systems with solid streamer
Chirp sub-bottom profiler acquisition and processing systems
Side scan sonar systems
Marine magnetometers
Seismic processing systems
Seismic energy sources
Single and multibeam bathymetric systems with backscatter capabilities
Underwater camera/video systems – drop and towed
Sediment sampling systems including drop corer, box corer and grab samplers
Water sampling systems
Water profiling systems
Current profiling systems.
All equipment is networked to a central navigation and data acquisition system for time-stamping and to ensure all data are accurately geo-referenced with respect to the vessel’s survey point of reference. Data is viewed for accuracy, coverage and completeness by onboard processors to enable onsite evaluation, facilitate re-survey if data quality is substandard or for route development or movement prior to departing the work location. For projects requiring data to be presented in near real-time for viewing and on-site decision-making, onboard processing can also be provided.
