The global seafloor geomorphology provides spatial layers (shapefile format) for 29 different seafloor geomorphic features mapped by Harris et. al. (2014). The layers were mapped based on the interpretation of the SRTM30 plus v7 global bathymetric model. Full details on the methodology can be found in the accompanying paper Harris, P. T., Macmillan-Lawler, M., Rupp, J., & Baker, E. K. (2014). Geomorphology of the oceans. Marine Geology, 352, 4–24. https://doi.org/10.1016/j.margeo.2014.01.011. The following geomorphic features are included in the data package: shelf, slope, abyss, hadal, shelf valleys, glacial troughs, coral reefs, escarpments, terraces, canyons, fans, rise, seamounts, guyots, plateaus, spreading ridges, rift valleys, ridges, troughs, trenches, sills, basins, abyssal hills, abyssal mountains, abyssal plains, low, medium and high relief shelf.
