Abstract : Large- and small-scale tectonism and volcanism shape seafloor topography near Mid-Ocean Ridges (MOR) and produce a variety of both regular and irregular morphological features. Large consistent features such as the Mid-Atlantic Ridge (MAR), central valley, and crestal mountains, are superimposed by smaller and more irregular features such as ridge offsets, ridge-parallel faults, and volcanic constructions. Many of these features are observable on Sea Beam swath-collected bathymetry. Our long-term objective is to quantify regularities in seafloor morphology and determine which features are best described by purely stochastic processes, which are suitable for deterministic physical and predictive models, and which fall somewhere in between.
