Description:
Abstract:
These data are high-resolution maximum likelihood classification of the seafloor offshore of Massachusetts, from Nahant to Gloucester. Approximately 127 km² of the inner shelf were mapped in the nearshore region between the 10m and 40-m isobath.
Purpose:
The purpose of this data set is to calculate a generalized sea floor bottom type using multivariate statistics, and high resolution depth (bathymetry) and acoustic backscatter (sidescan sonar) data.
These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey, Coastal and Marine Geology Program, Woods Hole Science Center. High resolution bathymetry, backscatter intensity, and seismic profile data were collected over 127 km² area covering a portion of the South Essex Ocean Sanctuary to characterize the surface and subsurface of the seafloor for regional geologic framework investigations.
geophysical data were collected during two different surveys. Survey RAFA03007 began Monday, 22 Sep 2003 (JD267) and ended on Tuesday, 14 Oct 2003 (JD287). RAFA04002 began 17 Apr 2004 (JD 108) and ended on 2 May 2004 (JD123).

Use_Constraints:
Data are not intended for navigational use.
These data should not be used at resolutions for which they are not intended. Additional ground validation should be conducted to use these data for applications other than regional geologic framework studies at spatial scales finer that 1:60,000.
Public domain data from the U.S. Government are freely redistributable with proper metadata and source attribution. Please recognize the U.S. Geological Survey (USGS) as the source of this information.

Data_Quality_Information:
Logical_Consistency_Report:
Bottom classification was calculated using the ISOCluster and Maximum likelihood tools combined in a custom modelbuilder model. Rigorous error analysis of the ISOCluster function has not been conducted. These data are intended for regional geologic framework investigations and should not be used for applications at fine scales without additional ground validation
