8:30 AM         - Some questions, amongst others, that should be addressed:
                  (1) Should OCMIP-2 be extended?

                  (3) After OCMIP-2, should we end cooperation?
                  (4) If not, what should we do and when?
                  (5) Should we be encouraging stronger links with ocean
                      transport modelers (WCRP/WOCE/CLIVAR) and ocean 
                      biologists and biogeochemists (other IGBP projects)?
                  (6) If so, how?
                  (7) What about links with other comparison projects
                      (e.g., TRANSCOM and CMIP)?
