DOI: 10.1111/sed.12935
Abstract: Repeated multibeam echo‐sounder surveys can provide information on developing stratigraphy over large areas and during periods when environmental conditions are known. In this study, analysis encompasses 13 time‐separated multibeam echo‐sounder surveys between 2002 and 2010… read more here.

DOI: 10.1121/1.5014973
Abstract: Multibeam echo sounders (MBES) are tools used to gather geophysical information on the seafloor and watercolumn which are important for feature detection, identifying gas seeps, and characterizing the seafloor, among others. At high frequencies (>100… read more here.

DOI: 10.1190/tle36040304.1
Abstract: Multibeam echo sounder (MBES) bathymetry and backscatter data from the 2013 R/V Falkor survey are used to define the Cretaceous–Paleogene (K-Pg) boundary deposit outcropping on the Campeche Escarpment and to characterize large-scale erosional processes on… read more here.
