Bathymetry, also referred to as hydrography, is the process of mapping underwater topography, and measuring depths and contours of the ground beneath water bodies such as rivers, ponds, lakes, and oceans.
Many bodies of water fall under a variety of provincial, territorial or federal regulations, and construction is often subject to environmental and other assessments that require an understanding of what lies beneath the water’s surface. Bathymetry is an important tool to collect this type of data.
As such, a hydrographic survey is essential for the construction of new bridges, pilings, offshore drilling platforms, and a wide array of other marine construction projects. Challenger uses a broad range of bathymetric technologies, such as echo sounding or sonar with single-beam, multi-beam or side-scan capabilities.
Survey equipment can be mounted to small watercraft or even a Remotely Operated Vessel (ROV). Shallower areas may also be surveyed using conventional survey, light aircraft, or even drones. This data, in its raw form, must be compared to other data sources, processed and corrected as per the requirements of the project.
Challenger has extensive hydrographic project experience in and around Calgary, Edmonton and across Alberta, as well as with remote and often challenging locations in the Yukon, Northwest Territories, and Nunavut.
