1999 Projects: ROV improvementsBenthic box-core systemProject lead/manager: Mark Brown An important requirement for conducting comprehensive, multidisciplinary research at the sediment-water interface (seafloor) is the ability to recover sufficient quantities of undisturbed sediment for sampling. Studies involving pore-water chemistry, biological sampling, and grain-size and stratigraphic (rock-layer) analyses all require substantial volumes of sediment. State-of-the-art sediment samplers deployed by ROVs use the vehicle manipulators for placement and actuation of a closing mechanism to retain the sample. Historically these samplers have been cumbersome and awkward to deploy by ROV. Under this project we will acquire and evaluate commercially available box-core devices and determine the most efficient means of improving the deployment procedure and closing mechanism. The evaluations will serve as the basis for a design of a versatile and reliable tool that will be capable of performing the full range of functions for multi-disciplinary use.
