Strategy of environmental assessment for CO2 ocean sequestration

CO2 ocean sequestration research should focus on determining effectiveness as well as environmental consequences. To investigate the validity of CO2 ocean sequestration, it is important that dissolution and dispersion behaviors of sequestrated CO2 into the ocean are understood. In addition, ocean environmental impact including marine ecosystem should be predicted. Sequestration research requires development of new cost-effective observation technique to monitor dilution and diffusion of sequestrated CO2. In order to assess the environmental impact of the CO2 ocean sequestration by seagoing observation, several technologies (in-situ pH/pCO2 sensor, tracking neutral buoy system, towing multi-layer monitoring system, automatic elevator) were developed and the performance of these technologies were confirmed by the sea trials.
