| * » Abstract |
Ocean sediment thickness contours in 200 meter intervals for water depths ranging from 0 - 18,000 meters. These contours were derived from a global sediment thickness grid distributed by the National Geophysical Data Center (NGDC). The NGDC grid was compiled from various existing sediment thickness maps and drilling cores, and has a cell resolution of 5 arc seconds. Sediment thickness data is typically acquired through two methods. Seismic (or sub-bottom) profile technologies rely on powerful pulses of low-frequency sound which penetrate the substrate and return information about substrate thickness, character, and stratification. The data are collected along transect lines and require interpolation to create comprehensive maps. Sediment thickness is also determined by direct measurement through coring, which provides more detailed information but only at discrete sites. Coring data can also be interpolated to form area maps, and to help interpret the seismic data. |
| * Purpose |
To support ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the National Environmental Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act. |
