          Bathymetry Survey.
        Entity Type Definition: 
          The determination of ocean depths or the general configuration of the 
          sea floor as determined by the profile analysis of depth data, using 
          a multibeam, wide-swath echo sounder. Depths are measured directly 
          below and transverse to the ship's track. The width of the swath is 
          a function of the number of beams and their aperture.
