The objectives of this laboratory, airborne, and satellite research are to develop methods for (1) ccurately measuring the inherent and apparent optical properties of the ocean; (2) nferring biological and geochemical constituents from the optical properties; (3) sing surface layer constituent maps to understand the marine biosphere, global biogeochemical cycles, and climate variability; (4) nvestigation of the interactions between physical and biological processes; and (5) comparison studies of products from OCTS, POLDER, MOS, SeaWIFS, and MODIS. Prime considerations include the role of marine primary production and dissolved/particulate organic matter in the global carbon budget and the couplings between physical and biological processes. Current research focuses on the analysis of satellite Seastar/SeaWiFS (Sea-viewing Wide-Field-of-View Sensor) data, preparations for MODIS, development of new instruments and techniques for making in situ measurements and for calibrating optical instruments, and use of Airborne Oceanographic Lidar and Ocean Data-Acquisition System data to estimate phytoplankton and organic matter distributions and their variability on local to global time scales. Global, basin, and regional time-series data are used for investigating the coupling between physical and biological processes in time scales of days to years. We use laboratory and airborne programs to develop new active (laser) and passive (solar) remote-sensing techniques for measuring oceanic optical properties and inferring corresponding constituents. Potential research areas include ship- and ground-based laboratory sample analysis, optical sensor design, calibration, and deployment; oceanic radiance modeling and algorithm development; ocean ecosystem modeling; and primary productivity modeling.
