Overview
The aim of this observation is to understand impacts on environments (water and sedimetnt quality, plankton and benthos) by the tsunami . Specifically as follows.1. Distribution and origin of deposited materials in Onagawa Bay.2. Distribution of harmful chemicals in fisheries grounds at Onagawa Bay.3. Ecological succession of benthic community in fisheries grounds at Onagawa Bay.4. Monitoring of growth and survival of Japanese scallop as indicator of environments in fisheries grounds
