DELP 1988年度沖繩トラフ海域研究航海報告 : 4. DELP 88, 第5海工丸航海で採取された堆積物資料について
application/pdf Surface sediment samplings were made using a piston corer at six sites in the central grabens of the Okinawa Trough during the DELP88 leg. 2 cruises on the Kaiko-Maru No. 5. Three sites (P-1, P-2 and P-3B) were located in the southern Okinawa Trough, and the other three sites (P-5, P...
