23 Apr 2010 This cruise is a site survey of Integrated Ocean Drilling Program (IODP) campaign, planned primarily for the purpose of recovering two suits of mooring, which had been set in the northern Izu-Bonin arc area during KY09-04 cruise for monitoring sea current variations at the site on which deep drilling with the Chikyu’s riser system is proposed in IODP proposal 698-Full2 and 698-Full2-Addendum (Tatsumi et al., 2007, 2009). It is very important for planning and implementing a safe riser drilling program to know vertical profiles and time variations of the actual sea current at the site. The data obtained shall be used for the analysis on riser behavior in high current conditions (Kuroshio Current). In addition, seafloor bathymetry and sea current surveys around the site was intended to be conducted supplementary in the night and redundant times with the shipboard multibeam bathymetry system and the hull-mounted ADCP as much as possible for increase the amount of our dataset.
