The International Coastal Research Center is located in Otsuchi Bay on northern Japan’s Pacific coast. The cold Oyashio and warm Kuroshio currents foster high productivity and biodiversity in and around Otsuchi Bay. The large earthquake and tsunami on March 11, 2011 resulted in serious disturbance to the nearby coastal ecosystem. It is very important to monitor physical, chemical, and biological aspects of the ecosystem as it recovers. Thus, we intend to reconstruct the ICRC in Otsuchi in order to contribute significantly to international coastal research.
