Bathymetric Surveys

Ollerhead & Associates provides highly accurate hydrographic surveys throughout the Northwest Territories and Nunavut. Our extensive experience and advanced technology allow us to conduct and manage large-scale projects across vast geographical areas.

We use advance sonar systems, including single and dual-frequency single-beam echo sounders, multibeam echo sounders, side-scan sonar, and sub-bottom profilers, to provide precise bathymetric data for various water environments, such as rivers and coastlines. Our surveys deliver both raw and processed data, ensuring complete flexibility for your needs.
