What are the roles of the hydro surveyor?

Hydrographic surveying is a specialized role that requires knowledge of the underwater environment, global positioning systems, and sound navigation systems.

Hydrographic surveyors, also known as hydrographers, use state-of-the-art technology to produce detailed plans of the seabed, harbors, and waterways. The role involves measuring and mapping underwater surfaces and studying the morphology (construction) of the ocean floor, showing the depth, shape, and contours.

They specialize in precise positioning, data acquisition, and processing in onshore or offshore marine environments. Surveyors usually spend time onboard survey ships and drilling platforms.

The information you’ll collect is used in:

  • the production of charts and related information for navigation
  • dredging
  • locating offshore resources (oil, gas, aggregates)
  • positioning offshore wind farms, oil platforms, and subsea cables
  • planning dock installations
  • Monitoring erosion.
