Description:
Abstract:
Interpretation of the sea-floor substrate types in the study area from the combined data collection techniques. In general, the entire mapped area was observed to have coarse-grained sediment, i.e., sand-to-boulders or bedrock outcrops. Most of the region can be characterized as having mixed grain sizes, with significant differences in the amount of the largest rocks. These differences have been characterized by three levels of boulder abundance for the mixed sediment: low, medium and high boulder abundance (Figure 8). These three levels were mapped using the raw backscatter data and the substrate classification map and are equivalent to average boulder abundances of less than 10 boulders/km2, 10-10,000 boulders/km2, and greater than 10,000 boulders/km2, respectively.
Purpose:
These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) software to display geologic and oceanographic information.

Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.
Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in ArcInfo format, this metadata file may include some ArcInfo-specific terminology.
