In 2002,the NMRI started a new international joint research, OACE, Ocean Abyssal Carbon Experiment, with the Monterey Bay Aquarium Research Institute (MBARI, USA) and the University of Bergen (UoB, Norway). The purpose of OACE is to accumulate the basic data on the long-term stability of CO_2 stored on the ocean floor at depths>3500m where liquid CO_2 is gravitationally stable and to evaluate its environmental effects. For this end, several filed experiments at Monterey Bay are planned to get the scientific data concerning the dissolution rate of CO_2,pH distribution around stored CO_2 and the interaction between CO_2 and sediments. The preliminary experiment was conducted in February 2003 at depths 700&800m to provide the know-how and skills for the following experiments at depths>3500m after October, 2003. The experimental procedures and outcome are summarized in this report.
