Abstract
In the fall of 2005, experimental trials to integrate the Free-Fall Cone Penetrometer (FFCPT), an in situ sediment profiling tool, with a Moving Vessel Profiler (MVP), an automated profiling winch, from a vessel underway were completed in conjunction with DRDC Atlantic aboard the CFAV Quest as part of scientific cruise Q290. This experimental work revealed several areas in which further R&D was required. This Contract Report details the work completed by Brooke Ocean Technology Ltd. (BOT), developer and manufacturer of both the MVP and FFCPT, to further integrate the two products. The primary development efforts were to improve methods for data handling, to permit the viewing of FFCPT data in real-time, to investigate the performance of the FFCPT sensor suite, and to upgrade the MVP to further its operational capability and to improve the interface with the FFCPT. These developments are consistent with the primary goal of the work: to develop the system as an effective tool for Rapid Environmental Assessment (REA) of in situ seabed properties. This effort culminated in a successful demonstration of the system’s REA capability aboard the Maritime Coastal Defence Vessel (MCDV) HMCS Summerside in October 2006.
