Fabrication and Testing of a Rapid Sampling Profiler for Energetic, High Ship Traffic Coastal Enviro
Abstract
This proposal seeks to acquire a new capability in long-dwell measurements in energetic coastal regions, such as straits and estuari,es, where strong currents and significant ship traffic pose a threats to instrumentation that is attached to moorings near the ocean, surface. The Rapid Sampling Profiler (RSP) system will be designed, fabricated and tested in strait and estuarine environments.Key, design elements of the RSP system are: 1.Profiling driven by a winch that is mounted to a platform anchored to the sea floor,2.Winc,h payout speed of 1 m/s, allowing full water column profiling in currents as strong as 1.5 m/s,3.Operational depths of up to 100 m,4,.Profile rate of once per hour,5.Profiling package with conductivity, temperature, depth (CTD) sensors and a telemetry system (using, cell phone technology) to transmit date once per day.6.Bottom-mounted acoustic Doppler profiler to measure full water column profil,es of current velocity.7.Bottom-mounted CTD to measure time series of bottom temperature and salinity.The RSP system advances the ca,pability of making highly-resolved measurements in coastal regions of strategic value and scientific interest, such as marine strait,s. Components of the system include off the shelf technologies (ADCP and CTDs), an integrated profiling/telemetry package to be dev,eloped and provided by a commercial supplier, as well as custom components designed and fabricated at Oregon State University (winch, and winch controller) and Woods Hole Oceanographic Institution (bottom lander and winch power supply). The RSP system will be test,ed in two high-current environments: Vineyard Sound and the Columbia River estuary.
