This data set contains shoreline rate of change statistics for New York State coastal wetlands. Analysis was performed using the Digital Shoreline Analysis System (DSAS), created by U.S. Geological Survey, version 5.0, an extension for ArcMap. A reference baseline was used as the originating point for orthogonal transects cast by the DSAS software. The transects intersect each polyline vector shoreline establishing intersection measurement points, which were then used to calculate the rates of change. End-point rates, calculated by dividing the distance of shoreline movement by the time elapsed between the oldest and the most recent shoreline, were generated for wetlands where fewer than three historic shorelines...

The dataset is composed of four tables containing environmental DNA (eDNA) data, fish capture data, and site location information from Round Goby (Neogobius melanostomus) surveys conducted on parts of the Champlain Canal and upper Hudson River, and adjacent areas, in New York during 2022 and 2023. First posted May 5, 2022, ver. 1.0 Revised June 2022, ver. 2.0 Revised August 2022, ver. 3.0 Revised November 2022, ver. 4.0 Revised February 2023, ver. 5.0 Revised May 2023, ver. 6.0 Revised June 2023, ver. 7.0 Revised September 2023, ver. 8.0 Revised October 2023, ver. 9.0 Revised December 2023, ver. 10.0
The Hudson River, New York, was contaminated with polychlorinated biphenyls (PCBs) from two General Electric plants over a period of ~30 years and PCBs are still present in sediment and biota today. The river provides habitat for a variety of plants and animals, including native freshwater mussels. Although little is known about mussels in this river, managers were concerned that a 7-year remediation program to remove PCB-contaminated sediments could affect mussels. From 2013-2019, we conducted stratified (non-remediated, before remediation, after remediation) quantitative surveys across 17-pool-stratum combinations across nine pools. Sampling was done during August through October of each year. At each site, divers...

The New York State Department of Environmental Conservation (NYSDEC) is developing a unit management plan/environmental impact statement (UMP/EIS) for the Hudson Gorge Primitive Area, an area of Forest Preserve land encompassing a scenic stretch of the Hudson River in the Adirondack Park. Two goals of the UMP/EIS are to inventory natural resources and ecosystems and take actions to protect those resources while providing for appropriate types and levels of public recreational use. Because of the river's extensive whitewater reaches, it is the setting for a commercial rafting industry that operates during spring, summer, and fall. To increase flows in the Indian and Hudson Rivers, the Town of Indian Lake conducts...

The dataset is composed of two tables containing data collected during screening surveys for invasive Round Goby (Neogobius melanostomus) on the Eastern Erie Canal in New York. Environmental DNA using water samples and traditional fish surveys using benthic trawling, seining, and trapping were conducted twice annually at 12 sites on the Eastern Erie Canal between Oneida Lake and the Hudson River from 2016-2019. Study sites were selected to be approximately equidistant apart (~ 20 km) while also taking advantage of suitable access points. Within a study site, the exact areas that were sampled were often staggered by 500 m or occasionally more in order to find appropriate habitat for each gear type (i.e., wadable...
