Overview

We conduct the geographic survey off Onagawa for creating a detailed bathymetric map of the Sanriku coast after the earthquake and tsunami. We also conduct the hydrographic observation using CTD-system to obtain the information of hydrographic structure and to collect seawater samples for analyzing biological and chemical components. Lander was deployed about 1,000m depth off Otsuchi to conduct long-term monitoring of marine environments near the seafloor.

Investigation Item and Data Acquisition

Investigation Item	Data Acquisition
Measurement of water temperature, salinity, dissolved oxygen, fluorescence and others with CTD system	Water temperature, Salinity, Dissolved Oxygen, Transmission, Fluorescence, water samples
Measurement of water temperature, salinity, dissolved oxygen, fluorescence and turbidity with FRRF-Rinko profiler	Water temperature, Salinity, Dissolved Oxygen, Turbidity, Fluorescence
