We present the summary and application of a new MATLAB/GIS technique for the quantification of gradient defined features in submarine environments. The technique utilizes MATLAB scripts to convert bathymetry data into a gradient dataset, produce gradient maps, and most importantly, automate the process of defining and characterizing gradient defined features such as flows, faults, landslide scarps, folds, valleys, and ridges. The features are defined according to strict gradient threshold criteria ...
