Abstract : The long term goals of this research were to acquire and use spatially overlapping swath bathymetry data sets at different scales using multibeam echo-sounders, for use in characterizing the statistical nature of the deep sea floor in the contexts of marine geology and ocean acoustics. The work included construction of a deeply towed multibeam swath mapping sounding system that can be operated as a part of our Deep Tow system (Spiess and Lonsdale, 1982), seagoing work to validate system capability, an initial expedition to use the system in the Pacific Natural Laboratory site (9 deg N, 104 deg-30' W) and subsequent data reduction and dissemination.
