  2. WOCE/JGOFS & other data

  3. Regional cp/POC Regressions Atlantic Pacific Arabian Sea Ross Sea

  4. SAVE Data Set: Dec-Apr 1987-89

  5. APFZ Data Set: Dec’97-Mar’98 OAD, m k6 k7n k7s k8 k9n k9s

  6. Global One Attenuation Depth (OAD) Summer z, m Winter

  7. SeaWiFS products vs cp regressions: SAVE () & APFZ ()Data Chlorophyll concentration, mg m-3 Diffuse attenuationcoefficient K490, m-1 Normalizedwater-leavingradiance LWN(555),mW cm-2mm-1 sr-1 Integrated Chlorophyll CHK,mg m-2
