SPATIAL PATTERNS IN ESTIMATED PHYTOPLANKTON BIOMASS ON GEORGES BANK COMPARED AMONGST A STEADY STATE N SUPPLY MODEL, SEAWIFS OBSERVATIONS OF OCEAN COLOR, AND ALONGTRACK FLUORESCENCE DATA
Using a simple first order model of seasonal fluxes of nitrate on Georges Bank, phytoplankton biomass is predicted for three distinct hydrographic regimes. The Bank regimes have been defined by numerous US GLOBEC broadscale and process cruises between 1994 and 1998 as being essentially well mixed, frontal, or stratified. The model predictions for each area are compared to estimates from seasonal compilations of SeaWiFS observations for these regions, and to estimates based on alongtrack fluorescence data obtained using shipboard and towed instruments. Next, specific patterns predicted by the model are compared to patterns observed, testing the model's ability to resolve the effects of the primary nitrate supply mechanisms. Finally, the influence of hydrographic boundaries that reorganize substantially on a scale of months on the ability of a climatologically based supply model to predict phytoplankton concentrations is considered.
