Abstract:
Oceanic net community production (NCP), defined as gross primary productivity minus community respiration, is an important measure of the ocean’s biological pump as it provides information on both the status of net carbon sequestration and the availability of carbon for export and trophic exchange. We propose to estimate NCP by tracking the localized, depth-integrated particulate organic carbon (POC) stock that has been produced or respired in situ. We will use the velocity fields from ocean circulation models to advect Lagrangian particles and consequently to trace water parcels. This in turn, allows monitoring and tracking of the temporal evolution of satellite-derived POC in the moving frame of surface water parcels. Depth-integrated POC will be derived from NASA MODIS data using several candidate empirical and semi-analytical models. Changes in the local POC stock will then be translated to corresponding changes in biologically-mediated dissolved inorganic carbon (DIC) and partial pressure of carbon dioxide (pCO2). Data from NASA’s SeaWinds sensor will be used to inform the air-sea carbon exchange estimates that are also needed to track evolution in the surface layer DIC. The approach enables estimation of the biologically-mediated DIC and will serve as validation for satellite-based pCO2 estimates. Our methodology will be applied globally, extending outward from continental shelves, which will form the focal point for this study. A synoptic picture of NCP and POC export from continental shelves will be constructed to gain an understanding of the role of continental shelves in the global ocean carbon cycle. As phase one we demonstrate the described methodology for a single region, the Gulf of Maine from here it will be extended to other data rich regions around the globe. Our work will be thoroughly validated using the UNH Coastal Ocean Observation and Analysis database, the Gulf of Maine Ocean Observing System buoy array and later, from coastal ocean observing systems around the world.
