Type of Activity: Sea floor mapping;Sea Floor Mapping

Information to be derived: Sea floor map;

Summary: The GLORIA sidescan sonar data are of excellent quality and complete coverage of the EEZ area was obtained. No down-time was experienced by GLORIA. The airgun, 10 kHz echo sounder and magnetic data are also of high quality with only a few hours of airgun data lost because of technical problems. The 3.5 kHz echo sounder records vary in quality from good to very noisy. This cruise was made scientifically successful and most enjoyable by the cooperation and competence of the ship's officers and crew and our multinational scientific staff.
