Hydrographic surveying, also known as hydrography, is the science of the measurement and description of features of the seabed that affect maritime navigation, marine construction, dredging, oil exploration and drilling, pipeline damage assessment and related disciplines.

A hydrographic surveyor will collect and record information about the physical features of water bodies. Depending on the requirements of the marine project, a hydrographic surveyor will measure the water depth and search for all types of submerged features, including ridges, banks, wrecks, which may rise from the seabed of those water bodies. A hydrographic surveyor may also gather information on the water levels, tides, currents, and other physical parameters of water bodies, including the salinity and temperature of the water.

Data is collected through various means, such as multibeam echo sounders, and is used for the production of nautical charts, tidal predictions, and volume calculations, or used for other maritime practices, for example, dredging.

Hydrography is an essential activity to an island nation such as Australia. It underpins maritime trade and is essential to support coastal infrastructure, resource exploration and export, environmental awareness, and coastal zone management.

Meteorological and oceanographic (metocean) processes should be understood before design and construction of any port, marina, or offshore structure. Without clear knowledge of the prevailing metocean conditions (wind, wave, current and tide) the likelihood of project design and engineering failure is likely, if not certain.

We produce high-quality environmental data and provide clients with expert interpretation. Upholding our stringent quality assurance principles ensures we meet the rigorous requirements of the offshore and maritime industries as well as regulatory, defence and government agencies.
