- 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)

- Data Quality Information
- Attribute Accuracy Report
- All sediment grab samples were positioned using Differential GPS (DGPS), with accuracy within 1 meter. The polygon borders are based on the samples (spaced an average of 0.5 km apart) and the sidescan sonar data. The sediment type polygons represent the general trend, but local misinterpretations are possible.
- Logical Consistency Report
- No information provided.
- Completeness Report
- The data cover the Hudson River Estuary from the Verrazano-Narrows Bridge to Troy, with the exception of some areas shallower than 4m, which have not been surveyed and sampled completely.

- Attributes
- type
- Sedimentary environment type based on interpretation of
sidescan sonar, bathymetry, and sub-bottom data
- Deposition - thin
- Low backscatter; Sub-bottom data shows thin (50 cm) usually transparent layer of sediment accumulation
- Deposition - thick
- Low backscatter; Sub-bottom data shows thick (50 cm) usually transparent layer of sediment accumulation
- Deposition - over bedrock
- Low backscatter; Sub-bottom data indicate bedrock underneath thin drape
- Deposition - unres. thickness
- Low backscatter; Sub-bottom data are not available or not clear enough to identify thickness of layer
- Erosional - truncated
- Sub-bottom data show indication of truncated stratigraphy outcropping on the river bottom. This class can only be identified where good sub-bottom data are available.
- Erosional - bedrock
- Multibeam bathymetry and sidescan data show bedrock outcropping at the surface. In general, no sub-bottom penetration.
- Erosional - non-deposition
- Moderate to high backscatter; multibeam may show smooth or rough surface. Sub-bottom does not show any indication of recent drape or truncated reflections. Applies to areas where there is no clear indication of deposition or other dynamic classes. No 7Be radionuclides where analysis exists.
- Dynamic - waves
- Regions with waves imaged with multibeam or sidescan
- Dynamic - scour
- Typically located around obstacles such as bridge abutments. Moderate to high backscatter, rough surface in multibeam bathymetry. No penetration and/or rough surface in sub-bottom data.
- Dynamic - debris
- Areas of complex morphology that includes small mounds of potential dumps or debris flow deposits. Often these areas show sign of scouring and sediment tails around individual features.
- Dynamic - lineation
- These are bedforms that are parallel to the current in contrast to the waves/dunes, which are typically aligned perpendicular to the current. Examples of lineations with distinct topographic relief are found in the Highlands.
- Dynamic - drift
- Regions characterized by deposition in the lee of obstacles. Often scour is also evident along the edges of obstacles so that regions of dynamic drift are characterized by both deposition and erosion.
- Dynamic - streaks
- Features visible in the backscatter are aligned along the current but have not evident topographic relief. Examples of these features are associated with the Newburg Beacon Bridge (A2).
- Dynamic - slump
- Features that are found a few times in the interpretation for example the slump structure along the edge of the channel adjacent to Catskill Creek, and the slide off of stony Point.
- Unsurveyed
- These regions are not classified due to lack of data coverage. These are generally the shallow regions that were not surveyed.
