Predicting bottom current deposition and erosion on the ocean floor

Mapping sediment deposition and erosion by thermohaline ocean bottom currents is important for the development of infrastructure, future geo resources understanding sedimentology contourites abyssal wavefields. However, only a limited percentage (estimated 20%) floor has been mapped directly through seismic or sonar imaging. To better delineate where zones current exist, we develop prediction from numerical model solutions sedimentological measurements floor. This achieved integrating three types data, which include following: (1) shear stress run HYCOM model; (2) sedimentation rates lithospheric age thickness GlobSed Model; (3) measured extents deposits observations. Shear stresses inside outside allow us to quantify conditions that are conducive deposition. These then extrapolated displayed on 1/12° arcsecond resolution map world's oceans validated comparison with known, systems. Based our prediction, around 12% significant while 1% erosion. Most activity occurs impinge upon like continental slopes some areas plain. Deposition also occur constriction takes place as in straits seaways. Inland basins (i.e. seas) shelves mostly disconnected global-ocean conveyors and, therefore, have Mid-ocean ridges little due low supply.
