Description:
Abstract:
The sedimentary environment interpretation is based on the evaluation of Chirp subbottom 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:
Attribute_Accuracy_Report:
All samples were taken using DGPS positioning. The horizontal accuracy is +/- 1 m. The outline of the different features are based on the samples that were spaced in average ~0.5 km apart and on the sidescan sonar data. 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.

Process_Description:
Sedimentary environments are based on the evaluation of the Chirp data in conjunction with the backscatter and bathymetry data. We distinguish the following classes: 1) Depositional environments are identified as regions with low backscatter that ideally can be seen overlying other strata. A clear example of a depositional environment is the site off Hook Mountain (A1) where Cesium measurements have confirmed the interpretation of recent sedimentation. This also includes the high backscatter deposits associated with tributary mouths (A2, A3). We have developed 4 distinct subclasses. 2)Erosional/Non-depositional environments are defined as sites with clearly truncated bedding in the Chirp data, outcrops of bedrock as in the Hudson Highlands or where other information, stratigraphic or radionuclides indicate non-depositional. We have developed 3 distinct erosional/non-depositional subclasses; 3) The identification of dynamic environments is based on the morphology and the backscatter data. Within the dynamic regions it is possible that both erosional and depositional processes are active. A clear example of a dynamic environment is the sediment waves/dunes prominent in the upper reaches of the Hudson River Estuary. As these features migrate both deposition and erosion are active. We have identified several major subclasses for the dynamic environment.

Process_Description:
Processed bathymetry, sidescan sonar, and sub-bottom tracks were loaded into ArcGIS. Polygons were drawn manually in ArcGIS around the areas with distinct different characteristics and each polygon was assigned a certain type based on its character.
