Bathymetric

Hydrographic Surveys

Our experience in bathymetric surveys, habitat mapping and cartography is extensive, having completed surveys in many areas in Australia. Utilising a boat mounted DGPS and dual frequency sounder linked to a data logging program and a laptop we produce detailed habitat and bathymetric maps to Australian hydrographic survey requirements. Habitat types are ground-truthed by a digital single CCD drop camera which records to an Archos PMA440 unit with GPS overlay function for later review.

Selected Past Projects:

  • Fine scale bathymetric mapping of proposed new farming zones, to Australian hydrographic standards and Marine Farming Branch Standards
  • Bathymetric mapping for dredge planning and management for TasPorts in various regions throughout Tasmania
  • Developing the bathymetry and a proposed pipeline route for an outfall in Napier, New Zealand
  • Planning and environmental assessment for the scuttling of the Troy D, Mercury Passage, Tasmania
  • Bathymetry of Medang Harbour, PNG, for input into wave and dispersal models
  • Port development, Hobart, Tasmania (TasPorts; 2016)
  • Public boardwalk proposed development, Battery Point, Hobart (SKM/Hobart City Council; 2013)
  • Port development, Triabunna (Burbury Consulting/ Glamorgan Spring Bay Council; 2013)
  • Effluent outfall investigation, Derwent River, Hobart, Tasmania (TasWater; 2012)
  • Effluent outfall investigation, northwest Tasmania (TasWater; 2013)
  • Pipeline route planning and assessment, Dover, Tasmania (Tassal; 2011-12)
  • Domgas pipeline route, Barrow Island (Marengo Mining/COFFEY; 2009-10)
  • Irrigation pipeline route planning and assessment, Bridgewater, Tasmania (Tasmanian Irrigation, 2012)
  • Outfall investigation, Port Sampson, NSW (Worley Parsons; 2009)

Research Charters

Marine Solutions has three vessels to cater for a wide variety of project types and working conditions. All vessels are in commercial survey.

We have a purpose built planing hull 6.0m aluminium research vessel “The Second  Solution“, fitted with bathymetric and habitat mapping equipment, and with dive entry and exit fixtures for research divers. In addition, the vessel is fitted with computer logging equipment and towed video with recording capability. Furthermore it has powered lifting davits and sieving attachments for lifting and maneuvering heavy sampling equipment, a tender vessel and two sit-on-top kayaks.

Our outboard powered “The Small Solution” small rigid hull inflatable boat is suitable for near-shore rivers, lakes and sheltered shallow waters.

A recent addition to our fleet is “The Environmental Solution”. This vessel is a 6.0m Hobson trihull with twin 90 horsepower engines. It has powered lifting davits and sieving attachments for lifting and manoeuvring heavy sampling equipment, and is capable of accommodating our vessel-mounted ADCP set-up.  It is equipped with sounder and GPS for bathymetric mapping.  With a dive ladder and a very stable work platform, “The Environmental Solution” is a suitable platform for conducting dive work. It is primarily based in Macquarie Harbour for increased capacity in the west/north west region.
