Application of Gliders for Near-Real Time METOC Data Collection Capability for Battlespace Characterization

Abstract : The goal of the program is to substantially improve the uncertainty associated with vicarious calibration and characterization (VC2) of ocean color satellite sensors by combining hyperspectral apparent optical properties (AOP) and hyperspectral inherent optical properties (IOP) measurements in oligotrophic and coastal areas, with state of the art radiative transfer modeling. A modified Satlantic HyperPRO II hyperspectral radiometer is being used as a portable calibration quality instrument of radiometric uncertainty comparable to that demonstrated for Marine Optical BuoY (MOBY) instruments off Hawaii. By combining these numerous observational platforms, especially gliders that have been outfitted with physical and optical sensors, an efficient and integrated method for real time METOC data collection with Tactical Decision Aid evaluations can be developed. We propose to design and test an efficient, integrated method for the collection of physical and biooptical (METOC) data in littoral zones to support military operations. This will include an array of sensors that will operate cooperatively to provide improved and specific data collection capability for local air and sea conditions. The observational platforms will include gliders, moorings, drifters, gliders, ships, aircraft and satellites. The plan is to have two Calibration/Validation cruises in the Ligurian Sea on the NR/V Alliance to collect a comprehensive suite of bio-optical and physical data that can be used to improve our understanding of the physical and optical dynamics of a Mediterranean littoral zone, as well as provide initial parameterization and testing of METOC forecasting models.
