River Bottom Mapping
River Bottom Mapping
In 1996 the New York State Department of Environmental Conservation (NYSDEC) initiated the River Bottom Mapping Project, an effort to map the river bottom 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 sonar, as well as collecting ground truth data with sediment cores, grab samples, and sediment profiling imagery (SPI). The goal of the River Bottom Mapping project is the creation of a comprehensive data set that includes detailed interpretive maps of the physical environment of the floor of the estuary that can be used to support activities related to wildlife management, sediment and contaminant management, and protection of historic resources. An overview of the first phase of the benthic mapping project can be found in Bell et al. (2006). Nitsche et al. (2010) provide an analysis of 20th century deposition in Haverstraw Bay. Maher (2006) and Strayer et al. (2006) explore the relationships between provinces defined on the basis of the acoustic surveys and the distribution of macroinvertebrates. Investigations are underway to explore the habitat preferences of juvenile and adult Atlantic sturgeon. Data products can be accessed at the NYS GIS Clearinghouse.
