Description:
Abstract:
The sediment type interpretation is based on the grain size analysis of the cores and grabs with some guidance from acoustic backscatter data collected with sidescan sonar. Sediment profile imagery (SPI) has also been used to supplement these interpretations. Since the first guide in developing this interpretation is contouring the results of the grain size interpretation there is deviation from the side scan images. In most research on sediments, grain size data is given in phi intervals rather than in microns, millimeters, or inches. One phi unit is equal to one Udden Wentworth grade. Phi diameter is computed by taking the negative log of the diameter in millimeters. We have identified 9 major classes of sediment based on the Wentworth classification.
Purpose:
In 1996, the New York State Department of Environmental Conservation (DEC) initiated an effort to map the benthic habitat of the Hudson River Estuary as part of a larger Hudson River Action Plan. This project includes extensive mapping using sidescan sonar, sub-bottom profiling, single and multi-beam bathymetric sonars, as well as collecting ground truth data with sediment cores, grab samples, and sediment profiling imagery (SPI). The goal of the project is the creation of a comprehensive data set that includes detailed interpretive maps of the physical environment of the floor of the estuary.  An overview of the first phase of the benthic mapping project can be found in Bell et al. (2006)

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
All data samples were taken using DGPS positioning with a horizontal accuracy is +/- 1 m. The interpreted outlines of the different features are based on sediment samples that were spaced an average ~0.5 km apart and on the sidescan sonar images. The data represent general trends; but, locally, misinterpretations are possible.
Logical_Consistency_Report: None
Completeness_Report:
The data cover the whole Hudson River Estuary from Verrazano Bridge to Troy. Areas of the Hudson River shallower then 4 m have not been surveyed and sampled completely.

Phi diameter is computed by taking the negative log of the diameter in millimeters Samples have been classified into 9 different groups: Main class is based on largest grain size fraction. If the second largest grain size fraction was above 10% this has been used as a modifier.
