below, above or near the waterline

what we survey

We measure and model anything below, above or near the waterline in any format our clients require. We provide precise and accurate surveys of the total marine environment giving clients data they can rely on. We work on oceans, coastlines, seas, lakes, dams and rivers and are adept at surveying in hard to reach locations.

Our data and imaging is used to create navigational charts, calculate dredging volumes, inspect submerged infrastructure, monitor erosion, assist with the design & maintenance of marinas, help model for possible flood events, support scoping studies for oil & gas and undertake seabed & foreshore habitat mapping.
Discovery Marine Ltd., (DML) is New Zealand's largest hydrographic survey company.
