U.S. JGOFS Synthesis And Modeling Project Gets Underway

by Robert Armstrong

The U.S. JGOFS Synthesis and Modeling Project (SMP) will be launched this summer at a workshop on the role of oceanic processes in the global carbon cycle. To be held Aug. 13-19 in Durham, New Hampshire, the workshop will bring together empiricists and modelers for a week of intense discussion on how to achieve the central JGOFS goals of characterizing the processes controlling oceanic carbon fluxes on a global scale and predicting the responses of oceanic biogeochemical processes to anthropogenic perturbation.

The main legacy of this component of U.S. JGOFS will be the synthesis of knowledge gained from field and modeling studies into a set of models that reflect our current understanding of how oceanic processes affect the global carbon cycle. Attaining this goal will be neither simple nor straightforward, requiring as it must the synthesis and modeling of knowledge gained from the global survey of carbon dioxide (CO2) in the ocean, the time- series programs at Hawaii and Bermuda, the U.S. process studies in the North Atlantic, equatorial Pacific, Arabian Sea and Southern Ocean, and JGOFS studies conducted by our international partners.

The SMP steering committee considers it essential that the investigators who made measurements during these studies participate actively in the synthesis and modeling effort. The goal is to ensure that full and appropriate use be made of the findings of these investigations. Among the purposes of the workshop are to foster relationships between empiricists and modelers and to emphasize the committee's commitment to the continuing collaboration that will be necessary to achieve the goals of the synthesis and modeling project and, through them, the central goals of JGOFS. The specific objectives of this workshop are:

In support of these purposes, the SMP steering committee has proposed some provisional goals, which are to be discussed at the workshop:
