9415667 Dickey The University of Southern California will undertake a project to facilitate development, testing, and calibration of new and existing sensors and systems for ocean science research on a testbed mooring near Bermuda. The goal of this project is to test various sensors for long-term deployments as part of the Bermuda Atlantic Time-Series (BATS), JGOFS, and GLOBEC global change research projects. The project will make use of an existing mooring, Altomoor II, that is sponsored by the Office of Naval Research. The testbed mooring will serve two important functions: 1) to provide a platform for developing and testing emerging interdisciplinary sensors and systems and 2) to provide high frequency, long-term interdisciplinary data to sample variables relevant to upper ocean physics, optics, biology, biogeochemistry, and carbon fluxes at a site regularly sampled using ships and sediment traps. The project will initially focus on optical and acoustic instrumentation and will foster a stronger working relationship between instrument developers and ocean scientists.
