Abstract :As a part of the educational cruise (RN10 Cruise) for students of Faculty of Science, University of the Ryukyus, by T/S Nagasaki-maru, the scientific survey was carried out during May 22 to 28, 2010. We took seawater samples above a submarine knoll in the forearc area off Miyako Island, and ones in the southern Okinawa Trough for reference. We also recovered rock samples using a dredger at Miyako Seamount which locate in the southern Okinawa Trough. Granitic rocks were dredged, which may correspond to Omoto Granit in Ishigaki island. Surface sediments were sampled by an Okean-type grab sampler from an island shelf off Naha, which are composed of biogenic carbonate sand and gravel containing a large number oflive large foraminifera, Cycloclypeus sp.
