Status

As of April 1999, the US JGOFS Synthesis and Modeling Project comprises 41 research projects (and some 80 Principal Investigators) funded by the National Science Foundation (NSF), the National Aeronautical and Space Administration (NASA), the National Oceanic and Atmospheric Administration Ocean-Atmosphere Carbon Exchange Study (NOAA - OACES), and Department of Energy (DOE).  These projects comprise a broad spectrum of analyses designed to utilize existing JGOFS data sets (and others); and include both data synthesis and modeling at local, regional and global scales.  We anticipate that additional funding for the Synthesis and Modeling Project will be made available in the fiscal year 2000, and have identified important areas for future research below.

Future Directions

As the U.S. JGOFS Synthesis and Modeling Project matures and specific projects are completed, the foci for the program will be refined to emphasize emerging new scientific directions and remaining elements of the original implementation plan.  High priority will be given to proposals addressing the following topics of equally importance:

• synthesis of primary production, new production and export production (both particulate and dissolved)
• the mechanisms and rates of mid to deep water particle flux and remineralization as well as sediment diagenesis
• controls and distributions of calcium carbonate and silica production, transport and remineralization
• biogeochemical effects of trace metal cycling
• spatial and temporal extrapolation of biogeochemical flux estimates (e.g.export production) from local to basin and global scales
• development, evaluation and incorporation of mechanistically based, biological models for global carbon cycle simulations
• synthesis and modeling studies of the Arabian Sea, Southern Ocean, North Atlantic, ocean margins (with respect to role in basin to global-scale carbon cycle), and the set of U.S. and international time-series stations data.
