The second VOS was M/S Alligator Hope of MO Line Co., Japan, which operated from November 1999 to May 2001.
This container cargo ship operated between Japan and the U.S. West Coast at 5-week intervals. The calling
ports were Seattle in the U.S. and Vancouver in Canada. Oceanic pCO2 was observed between Tokyo and Seattle
and between Vancouver and Tokyo. From the 16 round-trips within the period, frequent observations of the high
latitude area in the Pacific were obtained. A fully automated onboard system was installed and its operation was
contracted out to an onboard seaman. The 6-year datasets obtained through Skaugran and Alligator Hope provided
useful information about the interannual variability of ΔpCO2 in the North Pacific, which has significantly smaller
amplitude than that in the Equatorial Pacific area.
