    • PAR in the water column was calculated using clear sky irradiance (36), the daily surface reflectance data retrieved from TOMS data, and the diffuse attenuation coefficient estimated from the POC sensor (37-39). PAR was averaged over the mixed layer.

    • -3) chlorophyll values which were found at cloud boundaries. To best match the SeaWiFS record, we averaged dawn and dusk mixed layer POC values obtained on odd days of our Carbon Explorer record and combined these with the "noon" data obtained on even days near the time of the SeaWiFS over pass (Fig. 3).

    • C-JGOFS POC/chlorophyll ratios in the mixed layer were approximately 70:1 (19, 38). As a rough approximation, we used chlorophyll estimated from POC data and the chlorophyll K relation of Smith and Baker (39).

    • We thank C. Moore and A. Derr (WETlabs) for developing the stabilized POC meter. The U.S. Coast Guard helicoptered Todd Wood (LBNL) and the two Carbon Explorers from Dutch Harbor, the Aleutian Islands, to the icebreaker Polar Star, and assisted in the deployment of the floats in the North Pacific. P. Lam assisted with the analysis of SeaWiFS data.
