Introduction Recent trends analysis examining the effectiveness of tidal wetland regulations and the regulatory program of the New York State Department of Environmental Conservation (NYSDEC) revealed that the regulations and regulatory program were highly effective in stemming the historic "fill and build" activities. However, the trends also revealed that tidal wetlands—specifically, low marshes—were disappearing. To help determine the cause(s) of this loss, the NYSDEC, in collaboration with Stony Brook University's School of Marine and Atmospheric Sciences (SoMAS) and the U.S. Geological Survey (USGS), established a monitoring program in 2008 that has been conducted on and in the tidal wetlands of East Creek,...

This dataset represents public and non-governmental organizations (NGO) beaches in the North and Mid-Atlantic. The data are part of a larger project, Inventory of Habitat Modifications to Sandy Oceanfront Beaches in the U.S. Atlantic Coast Breeding Range of the Piping Plover (Charadrius melodus) as of 2015: Maine to North Carolina. Beachfront land parcels in public or NGO ownership were delineated from a variety of sources, including county or municipal parcel data available online to the public (see Table 1 of Rice 2015b for a full list of sources consulted for Maine to New York). Public and NGO-owned beachfront parcels are delineated with narrow, lime green lines in Google Earth Pro. The public / NGO line segments...

This data release contains coastal wetland synthesis products for the geographic region of eastern Long Island, New York, including the north and south forks, Gardiners Island, and Fishers Island. Metrics for resiliency, including unvegetated to vegetated ratio (UVVR), marsh elevation, mean tidal range, and shoreline change rate are calculated for smaller units delineated from a Digital Elevation Model, providing the spatial variability of physical factors that influence wetland health. Through scientific efforts initiated with the Hurricane Sandy Science Plan, the U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands with the intent of...

Two marine geological surveys were conducted in Long Island Sound, Connecticut and New York, in fall 2017 and spring 2018 by the U.S. Geological Survey, University of Connecticut, and University of New Haven through the Long Island Sound Mapping and Research Collaborative. Sea-floor images and videos were collected at 210 sampling sites within the survey area, and surficial sediment samples were collected at 179 of the sites. The sediment data and the observations from the images and videos are used to identify sediment texture and sea-floor habitats.

This U.S. Geological Survey data release presents tabular data on nitrogen concentrations and loads for multiple nitrogen species, and river discharge data used in the analysis of data collected from October 1994 to September 2016. Data on flow and nitrogen concentrations were analyzed using the USGS EGRET R package, and the method of WRTDS (Weighted Regression on Time Discharge and Season). Data and outputs summarized are for water-quality data collected from 18 water-quality monitoring stations in the Long Island Sound watershed. Specific data in tabular format for this release include: calculated annual nitrogen concentration and loads, calculated annual flow-normalized nitrogen concentrations and loads by water...

The data are from the Sediment Placement Projects on Sandy Beaches in the U.S. Atlantic Coast Breeding Range of the Piping Plover (Charadrius melodus) prior to Hurricane Sandy.This dataset represents the approximate locations of sediment placement projects along the U.S. North Atlantic coast from Maine through Virginia prior to the time that Hurricane Sandy made landfall in October 2012.The sediment placement projects were identified as part of an inventory of habitat modifications to sandy beach habitat within the U.S. Atlantic Coast breeding range of the federally-threatened piping plover. Sediment placement projects included in the inventory were beach nourishment projects, storm damage reduction projects, beneficial...

This dataset represents beach scraping after Hurricane Sandy. These data are part of a broader project Inventory of Habitat Modifications to Tidal Inlets and Sandy Oceanfront Beaches in the U.S. Atlantic Coast Breeding Range of the Piping Plover (Charadrius melodus) as of 2015: Maine to North Carolina. Beach scraping modified sandy beach habitat in each of the states within the U.S. Atlantic Coast breeding range of the piping plover during the three years after Hurricane Sandy. The beaches of the Peconic Estuary of New York were the least modified by beach scraping, with only 0.02 miles (0.03 km) of sandy beach habitat modified by beach scraping between 2012 and 2015. Less than 1 mile (1.6 km) of sandy beach habitat...

This dataset represents beach armor after Hurricane Sandy, including outfalls and proposed sites. These data are part of a broader project Inventory of Habitat Modifications to Tidal Inlets and Sandy Oceanfront Beaches in the U.S. Atlantic Coast Breeding Range of the Piping Plover (Charadrius melodus) as of 2015: Maine to North Carolina. The total length of oceanfront shoreline between Georgetown, ME, and the North Carolina-South Carolina boundary that has been armored is at least 476.81 miles (767.35 km; 27% of the total shoreline length). This assessment is a minimum number because some structures are buried and not visible in aerial imagery; in addition, historical records or inventories of hard stabilization...

Groundwater data were collected in the spring and fall of 2008 from three sites representing different geological settings and biogeochemical conditions within the surficial glacial aquifer of Long Island, NY. Investigations were designed to examine the extent to which average vadose zone thickness in contributing watersheds controlled biogeochemical conditions and processes, including dissolved oxygen concentration (DO), oxidation-reduction potential (Eh), dissolved organic carbon concentration (DOC), and microbial dinitrogen (N2) production. Greatest N2 production was observed at the south shore of Long Island, which is characterized by a thin vadose zone, low DO and Eh, and relatively high DOC. Limited N2 production...
