Japan Coast Guard Hydrographic and Oceanographic Department (JHOD) and Institute of Industrial Sci ence, the University of Tokyo conducted joint survey in the Kuroshima Knoll in June 2010 to obtain the de tailed information about the pockmarks here and to develop the navigation accuracy of autonomous underwater vehicle. In the joint survey, accurate bathymetric data were obtained by using multibeam echo sounder installed on the survey vessel “Meiyo” and detailed bathymetric map of the Kuroshima Knoll was built. It is revealed that the pockmarks at the top of the Kuroshima Knoll are distributed in the depression (about 150 m in diameter). Backscattering intensity image collected by the multibeam echo sounder was drawn. High backscattering areas, which are caused by the distribution of cold seep carbonates were found at the top area of the Kuroshima Knoll. Key words : the Kuroshima Knoll, pockmark, bathymetry, backscatterJournal
