Investigation of Coastal Phytoplankton Dynamics by Assimilation Satellite Ocean Color Data, NASA-NIP

 

Funding period: 2006-2009

 

The project uses inverse modeling approach to retrospectively analyze SeaWiFS and MODIS ocean color imagery in the highly productive United States (U.S.) northeast coastal ocean. Coastal ocean circulation hindcasts will be generated for time periods in which ocean color images are available. Numerical method will then be applied to invert for the phytoplankton dynamics that must be occurring during the intervening period between two sequential color images. The resulting representations of the physical and biological properties will then be used for term-by-term diagnosis of the mechanisms controlling these extremely complex coupled systems. In particular, the modulation of growth rates through both light and nutrient effects and various physically-controlled contributions to fluctuations in phytoplankton biomass will be analyzed.
