\nThe NOAA Office for Coastal Management worked with the states of Maine, New Hampshire, and Massachusetts to develop a regional geomorphology data set which would form the framework for collaborative planning and assessment offshore in the Gulf of Maine. A contract was awarded to a private sector company to process NOAA's BlueTopo bathymetric products to generate CMECS geoforms for the area. The spatial domain of these data extend from the landward limit of BlueTopo tiles seaward to the 24 nautical mile Contiguous Zone boundary. The project used semi-automated methods so that features identified throughout the region would be consistently mapped. A second set of Interpreted Geoforms consisting of Deltas, Moraines, Paleo-deltas, Basins, and Cobble-Boulder-Complexes, and Estuarine Sediment Shoals were manually delineated and were intended to complement the other Geoform products visible in the Portal table of contents. A generally very conservative approach was taken to these delineations and the resultant features are only identified where the source bathymetry was of high quality. It is likely that the extent of these features may change as new bathymetry becomes available. View the metadata report for a description of data inputs, methods, and QA processes.
