Overview

We recover an ADCP, three Landers, two SEASAW systems which were deployed in KH-18-J02C and KS-17-J08C cruises to obtain variation of temperature, salinity, current and others for ecosystem model off Sanriku. We conduct the hydrographic observation with the CTD-Carousel water sampler system and the FRRF-Rinko profiler system at 28 stations. We also collect zooplankton.
