Bathymetry & Charting Surveys

MHS provides a complete bathymetric and charting service to cover any project scope and location. We utilise the latest technology in positioning and echo sounding systems to produce quality maps and charts of a designated area.

MHS personnel are Level 1 Certified Practicing Hydrographic Surveyors by the Australasian Hydrographic Surveyors Certification Panel (AHSCP) of the Surveying and Spatial Sciences Institute Australia and the New Zealand Institute of Surveyors and recognized Internationally by the IHO (International Hydrographic Organisation) – and – qualified and experienced Marine Geophysicists

Using multi-beam Bathymetric System technology, surveys can achieve 100% coverage of a survey area enhanced with high resolution images of the seabed to ensure that even metre-sized objects are detected and accurately mapped.

Digital side scan sonar systems are deployed when single-beam bathymetry is surveyed to produce high resolution imagery of the seabed topography and to map sand waves, wrecks, vessel scours, reef areas and man made objects such as anchors and debris.

Capabilities

MHS utilise the latest technology in positioning and sounders to produce quality plans and charts of the designated survey area. The sensors are calibrated to known values and interfaced to dedicated survey software onboard. MHS is capable of regular charting surveys for major ports, investigation surveys for new port developments and channels, dredging surveys, and scientific mapping.

 

 

Regular charting surveys for major ports to ensure shipping safety, including survey support for any associated dredging operations. This includes the initial pre dredge survey, progress surveys, and post dredge clearance surveys.

Investigation surveys for new navigation channels and remote area port developments. Hydrographic investigations can also include establishment of horizontal and vertical datum's, side scan sonar, seismic reflection profiling, environmental, current and tidal studies, and seabed sampling.

Scientific mapping of specific areas of scientific and/or environmental interest including bathymetry across reef areas and weather edges, air photo control and the production of composite map sheets of the Great Barrier Reef.
