• Digital Graphic Recorder.

  The Digital Graphic Recorder produces a continuous permanent graphic record of the sea floor and sub-bottom topography. The recorder generates a trigger pulse which is sent down two cables to energize a side scan sonar and\or sub-bottom profiler transducers. When the sonar echoes are received, they are sent up two cables to the recorder, and are electronically processed to produce a sonar image. This can be used to provide a high-resolution vertical profile of shallow sediments on the sea floor.

• Environmental Assessment

  Prior to the placement of underwater pipelines (or cables) it is necessary to determine what impact the construction will have on the environment or what hazards may be in place. Canadian Seabed Research Ltd. (CSR) offers a complete range of survey and marine services to engineering groups, mining and petroleum companies and government agencies working in coastal and offshore marine environments.

  Services include: pre/post lay cable and pipeline route surveys; petroleum geo-hazard site surveys and thickness to bedrock for marine engineering; seabed foundation surveys; ice scour hazard and modelling surveys.

  The same technologies and expertise used for this type of project can also be used for many other environmental applications including: pre/post dredging surveys of contaminated sediments; ocean disposal/sediment transport studies; sewage outfall mapping and monitoring; coral reef health mapping; contaminated debris search and recovery; aquaculture site selection studies.

• Integrated Marine Acoustic Profiling System (imaps) Profiling System.

  The Integrated Marine Acoustic Profiling System (IMAPS) enables accurate images to be generated of pollution from sewage outfalls, of damage to the seafloor by trawlers, and of the trails of iceberg scours.

  Three existing technologies are used in the new system. The first, is a side scan sonar unit which is towed behind the ship and provides a high-resolution, 2-dimensional image from the high frequency sound waves it bounces off the seafloor. The second source is a sub-bottom profiler, which emits low frequency acoustic energy which penetrates the seafloor to create a cross-section of the underlying geological sediments. This tool can penetrate to 50 m in soft silts and clays. The third device is called a micro-profiler which works like a sub-bottom profiler, but emits higher frequency sound waves and, therefore, achieves higher resolution of the uppermost 2-3 m of sediments. By integrating these technologies, new types of high accuracy information can be collected in a very cost-effective manner.
