Additional Documentation: Atlas Hydrosweep DS is a hydrographic "multi-beam echosounder" which provides, measurements of depths, signal strengths, and a "mean velocity of sound in, water" by 59 performed beams (PFBs) which cover a sector of 90 degrees below, the ship. In the "survey mode" the fan of PFBs is oriented across the ship's, axis, in the "calibration mode" it is oriented along the ship's axis. MBSystem's (LDEO) mbcopy command was used to convert the raw format to a URI, VAX byte order format from which the vertical beam was then extracted.
