Cruise Inventory Information

Long name Hakuho Maru cruise 49HH915_2
Short name 49HH915_2
Objectives and Narrative WOCE section P13C. CTDO2 casts with 24-place 12-liter rosette water sample were carried out at 68 stations along 165 E. Eight stations were occupied on 164 E and 166 E in order to calculate meridional geostrophic flows and zonal gradients of property concentrations. The other 60 stations were on 165 E, forming a part of the WHP P13. The interval of CTD stations was basically 60 n.miles, but it was shortened to 30 n.miles over the seamounts around 12 N and l9 N and near the equator between 5 S and 4 N

CTD stations were moved to 7 N and 10 N from 165 E to 164 30 E and the
stations at 8 N and 9 N to 164 E, in order to avoid the training area of US
navy. Six SOFAR floats were deployed at three locations in the Kuroshio Extension area just east of Japan. Three moorings of acoustic receiver for SOFAR were deployed in the Kuroshio Extension area just . Japan. Five moorings of current meters were deployed on 165~E. Each mooring has four or-five current meters between the sea bottom and the depth of 800 m from the sea surface. One mooring of current meters at 27*N, 168-E was recovered.
