AB: Ocean Drilling Project Leg 200 was the first leg in deep sea and ocean drilling history to conduct operations in the vicinity of a continuously operating broadband seafloor seismometer. In 1998 investigators from the University of Hawaii, Woods Hole Oceanographic Institution, and Incorporated Institutions for Seismology had installed a broadband, shallow buried seismometer at the site [Duennebier et al., 2002] and data has been acquired in real time in Oahu over the Hawaii-2 transoceanic cable. Hole 1224D was drilled, cased and cemented at the site so that a broadband borehole seismometer can be emplaced in the future. The noise from the JOIDES Resolution as it approached and left the site as well as during all on-site operations was observed. In addition we recorded shots with 80 cubic inch water guns during single channel seismic tests as well as whale songs and earthquake activity. The behavior of ambient noise levels near the microseism peak was also compared with local wind speed and sea state conditions as observed from the drill ship. This work was supported by a grant from JOI-USSAC. We would like to thank the Earthquake Research Institute at the University of Tokyo for a Visiting Professorship for RAS during which much of this work was carried out. [Duennebier, F.K., D.W.
