Fig. 8.11 a Single beam acoustics provides coverage only along discrete lines underneath the
boat track. While single beam returns can be harvested to provide information about the nature of
the seafloor (see Chap. 9), no continuous surface of measurements is available (from Purkis and
Klemas 2011, by permission of Wiley-Blackwell) b Swath systems, such as multi-beam
bathymetry provides complete surfaces of bathymetric information and allow imaging of the
seafloor with more complete information (image courtesy NOAA)
