Multi-sensor instrumentation on a FOCUS-1500 search and survey system

Summary form only given. A FOCUS-1500 ROTV has been fully instrumented for deep water search and survey applications using acoustic, optical and magnetic sensors for operations to 1500 meter water depth. The recent deployments of the system mark a number of firsts for deep water applications, including deepest operation of the FOCUS vehicle; deepest operation of a laser line scan system; deepest operation of a high resolution multibeam system; deepest operation of simultaneous surveying and mapping of an acoustic/optical/magnetic suite of sensors. The system has recently operated off the East Coast of the United States and the south coast of the island of Hawaii. Additional deep water surveys will be completed by the end of 1997. The system was designed for the following applications: pipelines inspection; telecommunications cable inspection; route surveys; environmental surveys; search operations and related studies. Data from all surveys is presented, including a route survey and site investigation of the Loihi Seamount, located south of the island of Hawaii
