In this cruise, a WHP like observation will be carried out in the sub-tropical/sub-arctic regions in the Eastern North Pacific.

A port will be made at Seward before the entrance to the arctic region.

4. Outline of Observation:

In the Eastern North Pacific, WHP P17 will be re-visited in the north of 30N. Main apparatus will be CTD+RMS and LADCP. The number of bottles on RMS will be either 24 or 36 at each P17 station. Observation items using sampled waters are planned to be, at least, Salinity, DO, nutrients, freons (11, 12, 133), TOC, delta 14C. IN the Chukchi and the Bering Sea, several CTD+RMS stations will be occupied with the bottom core sampling, if needed. Salinity, DO and nutrients will be analyzed using sampled water. Ocean ridar system will be operated at tens of stations both in the sub-arctic and the arctic regions.
