Status • On-line coupling (off-line in future?) • Initiated NPZD with climatology (NP) • Completed 1995 whole year run for NPZD • Gathered copepod data (GLOBEC,MARMAP, ECOMON, AZMP) • Testing CPD model (Pseudocalanus), impletmented “stage with mean age” method, testing “EOF” method • Ready for NPZD run in other GLOBEC yrs
