The korrong project – semi‐submersible imaging for environmental mapping in shallow water

In 1996 a unique vessel with an imaging pod that descends beneath the surface was developed to image the marine environment. The system is used to take photographs, make video transects, and to allow human observation. Water clarity normally limits the vessel's operation to less than six metres depth. Video transects are the most common usage of the vessel. Using the vessel, long distances are covered by video transect rapidly and cost effectively. Frames from these transects can be used to create mosaics or stereo pairs. Designed as a research tool, the vessel has proven itself a valuable operational asset in monitoring the shallow marine environment and demonstrated the technique of semi‐submersible imagery.
