| | Abstract | | The reflection seismic method, using the seafloor based sound source and the Vertical Cable Seismic, has been studied for the exploration of the ocean bottom hydrothermal deposits. On August 2013, the practical survey was conducted at Izena cauldron, Okinawa. The data were successfully acquired with 1 kHz Ricker wavelet and both direct wave and reflected wave are recorded by each hydrophone. In addition, some reflectors can be seen in the record section processed using seismic interferometry. Although a measure of success were achieved in data acquisition and processing, further examinations for appropriateness of processing flow, validity of interpretation and so on are required. |
