Seafloor margin map helps in understanding subduction earthquakes [PDF]
Eos, Transactions American Geophysical Union, 2005 Ecuador and southwest (SW) Colombia suffered widespread damage during the twentieth century as a result of some of the greatest subduction earthquakes and associated tsunamis ever recorded. In 1906, the Ecuador‐SW Columbia margin, located at the transition between the continent and deep ocean, ruptured over a 500‐kilometer length as a single great (Mw =

Multispectral Multibeam Echo Sounder Backscatter as a Tool for Improved Seafloor Characterization
Geosciences, 2019 The establishment of multibeam echosounders (MBES), as a mainstream tool in ocean mapping, has facilitated integrative approaches towards nautical charting, benthic habitat mapping, and seafloor geotechnical surveys. The combined acoustic response of the

Seafloor Segmentation Based on Bathymetric Measurements from Multibeam Echosounders Data [PDF]
, 2003 Bathymetric data depicts the geomorphology of the seabottom and allows characterization of spatial distributions of apparent benthic habitats. The variability of seafloor topography can be defined as a texture.
