| Outline of Final Research Achievements |
Deep ocean mining in a hydrothermal area needs careful environmental impact assessments in terms of preservation and mitigation of biodiversity. In order to take measures against environmental impact during the mining in a hydrothermal area, it is important to measure components of hydrothermal origin with high temporal and spatial resolution on site, and to understand the ecosystem in the hydrothermal environment. In this study, I have developed a measurement method of turbidity profiles using an Acoustic Doppler Current Profilers (ADCPs). Applying this method to the ADCP measurements in a hydrothermal area in the Okinawa, we verify that this method can extract turbidity data from echo intensities measured by ADCP.
