Multi-Scale Studies of Seafloor Topography.

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.
