usSEABED and the Marine Aggregates Resources and Processes Project (MARP)

usSEABED is the collaborative product of the U.S. Geological Survey, the University of Colorado, and other partners and provides integrated data from small and large marine research efforts by many entities - federal and state agencies, local authorities, universities, private and public consortiums. usSEABED includes surficial and subbottom information on grain size, composition, and applied-properties and is held in comma-delimited files, useable in most GIS and RDB programs.

Users of the data continue to work with and test the data for new purposes and products. The Marine Aggregates Resources and Processes project (MARP) is using the database to model offshore sand resources near New York and New Jersey (Bliss and others, 2009), conduct regional-scale assessments, and for producing interpreted GIS maps that can serve a variety of needs. Sand and gravel assessments are in-progress for Louisiana and similar assessments are planned for other regions.

Externally the data has been used for modeling mean grain size (Goff and others, 2008), managing Essential Fish Habitat (National Marine Fisheries Council, 2009), describing Atlantic Wolffish Habitat (Wollfish Workgroup, 2009) and dogfish habitat (Graham, M.S. Thesis), and establishing management plans for regional sediment resources (Masachusetts Ocean Planning, 2009). State organizations have used it to map important estuarine habitats (Hamlin, 2008), and private consulting firms have used it to establish basic sea floor geology for exploratory drilling.
