| Research Abstract |
We identified as following three topics. 1) Iron sedimentation period and timing, 2) Caldera forming process and sedimentation, 3) Hydrothermal process and Coral record. We identified 3 years long temperature records of ocean surface, floor and sediments with hydrothermal activity in Nagahama bay. Sediment core and coral core samples indicate sedimentation timing of Iron and record of volcanic activity.
