Overview
We deploy an ADCP, two Landers, two SEASAW systems to obtain variation of temperature, salinity, current and others for ecosystem model off Sanriku. We also conduct the hydrographic observation with the CTD system and the FRRF-Rinko profiler system. We also collect zooplankton.

Results and Future Plan
In the KH-18-J02C cruise, we moored two Landers, an ADCP and two SEA-SAW off Sanriku to obtain variation of temperature, salinity, current and others for ecosystem model. We also conducted the hydrographic observation using CTD-system to obtain the hydrographic information at 20 stations and collected zooplankton.
