Integrating Ocean Color Observations and Nowcast/Forecast of Bio-Optical Properties into the Naval Research Laboratory Coastal Ocean Model (NCOM)
Abstract
The long-term goal of this effort is to provide a framework for assimilating satellite ocean color observations into coupled bio-optical/hydrodynamic ocean models that may provide a forecast of the fully three-dimensional field properties that define the marine environment over a range of spatial/temporal scales and are of pertinent tactical interest to the U.S. Navy. The immediate scientific objectives of this long-term effort are to: (1) use satellite ocean color algorithms that quantify and partition near-surface inherent optical properties (IOP's) to establish a regional IOP climatology, with particular emphasis upon the partition of the multi-spectral absorption coefficient between colored dissolved organic matter (CDOM) and living phytoplankton biomass, (2) examine the relationship between IOP variance and three-dimensional thermal field variability as determined by existing data assimilative and interpolative systems (i.e., the Modular Ocean Data Assimilation System - MODAS), (3) use a combination of statistical inference and numerical modeling techniques to provide a three-dimensional optical property estimate (nowcast) that is informed by and integrated with systems that estimate the thermal and velocity fields, and (4) use results from and knowledge gained in objectives 1-3 to refine existing coupled real-time modeling efforts towards an efficient, accurate, and portable prognostic tool for the optical battle space environment.
