Abstract:
With this proposal we seek to improve our understanding of processes controlling carbonate system variability in coastal areas, and to demonstrate that ocean color satellite data are poised to play an integral role in this field of research. We will use Lagrangian tracking of virtual particles in combination with high resolution MODIS Aqua and MERIS satellite fields to distinguish the relative effects that biological and physical processes play in regulating the carbonate system of coastal waters. The proposed project expands upon novel work developed to estimate rates of biogeochemical change using ocean color data cast within the context of modeled velocity fields. Using output from a high-resolution general circulation model (GCM) we propose to track the carbonate system and biological variables from river mouths through the coastal zone onto the open ocean boundary. An application of these methods will provide estimates of processes affecting acidification including physical residence times, mixing, dispersion, and net local terms associated with community productivity.
