Description:
Abstract: This dataset provides sedimentary environments of the Hudson
River Estuary from Verrazano Narrows Bridge to Troy. Areas of the Hudson
River shallower than 4 meters have not been surveyed and sampled
completely. The sedimentary environment interpretation is based on the
evaluation of Chirp sub-bottom acoustic profiler data in conjunction
with acoustic backscatter and bathymetry data. It is subdivided into
depositional, erosional, and dynamic classes that are further
subdivided, depending on the details identified in the sub-bottom data,
or because of their location. A more complete description of this
interpretation can be found in Nitsche et al. (2004) and Nitsche et al.
(2005)
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)
