Abstract
The Moving Vessel Profiler (MVP) has been developed as an automated data collection tool that can be used from vessels while underway. It has been effectively used to collect mid-water oceanographic information to support science and hydrographic survey operations. The Free Fall Cone Penetrometer (FFCPT) has been developed as a geotechnical measurement instrument that can be deployed in a stand-alone (self recording) mode or from a slip ring equipped free-fall winch with the capability of real-time telemetry. The MVP and the FFCPT have been successfully integrated to arrive at a novel and tremendously efficient system to provide water column profile data and grain size analysis of the seafloor in support of numerous marine activities including science, hydrographic and naval applications. The MVP with FFCPT can make these measurements while the vessel is underway at 4-8 knots. The ability to collect this data makes the system a useful Rapid Environmental Assessment (REA) tool. This paper will describe in detail the MVP, FFCPT and the integration of the technologies. Some REA data collected during trials is then presented.
