OverviewTo estimate density and influence of the tsunami debris on marine ecosystems, diving researches will be concucted using the newly developed ROV "Crambon" off Miyagi and Iwate. High difinition TV images will be taken and biological samples and debris will be collected from the deep sea. In addition, sediment sampling will be conducted using a multiple coring system.
