Bathymetric Survey

Many bodies of water fall under a variety of provincial, territorial or federal regulations, and construction permits are 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.

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.

As such, a hydrographic survey is essential for the construction of new bridges, positioning pilings and 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). Challenger currently operates both. Bathymetric data for shallower areas may also be gathered using conventional survey, light aircraft, or even drones.

Challenger has extensive project experience collecting high-resolution bathymetry, as well as profiling imagery. Positioning data can be quality controlled using a GPS RTK Base Station on shore. Once the data is collected, we process it and compare it to other data sources. Challenger can then generate a report based on the specific project requirements.
