Significant changes in nitrogen loads to Jamaica Bay have likely occurred with progressive improvements to Water Pollution Control Plants (WCWPs) that discharge into the Bay. Data available from the New York City Department of Environmental Protection and others will be used to determine loads from WPCPs, combined sewer overflows, and the atmosphere. Selected wells within the USGS water quality database, including those near the landfills that are immediately adjacent to Jamaica Bay, will be used to determine concentrations of nutrients in shallow ground water that enter the bay from ground water seepage. To facilitate evaluation of ground water loads, an existing USGS Finite element model that simulates sub...

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,...
Studies of nearshore environmental health by the USGS focus on the interface between health and the environment, where interactions among people, the environment, and other living organisms affect the risk of toxicological and infectious disease. Understanding nearshore ecosystem health is complex, in part, because it is affected by a wide variety of environmental and anthropogenic stressors. The nearshore environment serves a variety of functions such as habitat for plants and animals as well as a variety of human activities. The introduction of contaminants can deteriorate these aquatic resources through degradation of ambient water quality. Contaminants introduced in this manner may accumulate in the sediments...
Scientific information, when reliably obtained and wisely applied, can strengthen our efforts to build resilient coastal communities before storms strike, and guide our response and recovery strategies after landfall. Documenting the height, extent, and timing of overland storm tide and wave dynamics across natural and man-made landscapes, is critical for improved storm-surge modeling for floodplain mapping and real-time forecasting. This leads to better planning, more effective early warning of storm-driven flooding, and strengthening of coastal resilience. The USGS Surge, Wave, and Tide Hydrodynamics (SWaTH) Network developed for the Northeastern Atlantic coast provides critical information on nearshore storm...

Fire Island National Seashore (FIIS) is located on the barrier island along the extreme southern shore of western and central Suffolk County, New York. Interspersed throughout FIIS are seventeen residential beach communities that in the summer months greatly increase in population due to the arrival of summer residents and vacationers. Wastewater from the numerous homes and businesses in the barrier island communities generally is discharged directly into the shallow ground-water system through use of private septic systems. Contaminants entering the ground-water system can pose a threat to coastal habitats, as they are transported by ground water that discharges to ocean and estuary shorelines. In October 2004,...

In 1979, the U.S. Geological Survey (USGS) entered into a cooperative agreement with Monroe County (MC), which, over the span of more than three decades, has resulted in more than 30 reports that have summarized flow and water-quality data at sites in Monroe County and have presented the results of investigations of particular water-related issues that existed in the County. The collaborative relationship between Monroe County and the USGS entails: - USGS training and oversight of MC personnel to conduct site visits and measure streamflow and collect water samples at monitoring sites; - analyses of water samples by MC in a certified environmental laboratory that routinely participates in a USGS quality-control program...

Introduction Ongoing efforts to improve the health of New York's South Shore Estuary Reserve (SSER) require continuously recorded water-quality data to understand the short-term effects of stormwater runoff and other pollution sources. To document the diel and tidal variability of water quality in the western bays of the SSER, the USGS monitors select physical and chemical parameters at two sites within the SSER. One site, station 01310740 on Reynolds Channel at Point Lookout, is near the estuary mouth and operated in cooperation with the New York State Department of Environmental Conservation (NYSDEC) and Town of Hempstead Department of Conservation & Waterways. The second, station 01311143...

Coastal Hydrology and Storm Surge Storm-surge is one of the most powerful and destructive elements of major storm events. Excessively high tides associated with storms can flood and inundate coastal areas, often moving sediment and altering coastal landscapes and drainages. USGS provides critical expertise in measuring storm surge and assessing conditions both before and after the storm. Through development of storm tide monitoring networks, data analysis, and data delivery, USGS provides vital information to help coastal communities prepare for and recover from storm surge events.

Beach and barrier dynamics for the Atlantic Ocean and Great Lakes can vary extensively based on the sedimentary environments of these systems. Likewise, the settings can be complex and include components of mainland beachs, barrier islands and dunes, tidal flats and barrier platforms, salt marshes and lagoons, ponds, alluvial fans and inlet deltas, to name a few. The combination of wave, tidal, and storm impacts to coastal morphology also can differ by geographic location. However, barrier islands and spits may be the most vulnerable to changing sedimentary conditions due to human intervention, periodic extreme storms, and accelerating sea-level rise. The USGS is working to enhance mapping of these dynamic settings...

The U.S. Geological Survey (USGS) is collaborating with the New York Department of State (NYDOS) Office of Planning and Development to prepare a new Long Island South Shore Estuary Reserve (SSER) Coordinated Water Resources Monitoring Strategy (CWRMS). Since 2000, when the last CWRMS was published, numerous research projects and studies are demonstrating several new threats to the ecologic health and resilience of the SSER. Contemporary threats include: Eutrophic conditions brought on by high levels of nutrients from sewage treatment plant discharges, stormwater runoff, groundwater seepage, and atmospheric contributions; Increased occurrences of harmful algal blooms in the past 15 years; and, Growing concern...

Problem Coastal communities are susceptible to damage from coastal storms and associated storm surge, and although tidal wetlands provide a buffer against shoreline erosion and aid in shoreline stabilization, they too are vulnerable to the action of storms. Tidal wetland dynamics need to be better understood, as they are also intrinsically valuable as nursery, feeding, and refuge areas for many commercial and recreational fisheries, and significantly contribute to the base of the marine food web. Wetlands trap sediments, reduce turbidity, and absorb nutrients and pollutants thereby improving water quality, and they provide many recreational opportunities. Tidal wetland stability needs to be assessed using a sediment...

The coastal areas of southeastern New York (fig. 1) are highly vulnerable to tidal flooding (fig. 2). Timely evacuation of people from flood-threatened areas in advance of approaching hurricanes and nor'easters (northeast coastal storms) requires adequate flood-warning time. To begin addressing this need for immediate information on coastal flooding, the U.S. Geological Survey (USGS), in cooperation with the Town of Hempstead Department of Conservation & Waterways, Village of Freeport, and New York State Department of Environmental Conservation, has operated a network of real-time tidal water-elevation and meteorological stations since 1997 in the coastal areas of Long Island and New York City. Each tidal water-elevation...

Problem The presence of pathogens in Long Island marine embayments and the hazards they pose to marine resources and human health is of increasing concern. Many waterbodies on the New York State Section 303(d) List of Impaired Waters have pathogens listed as the primary pollutant that are suspected to originate from urban/storm runoff. There is neither a clear understanding of the relative magnitude and geographic origin of sources of loadings of pathogens (from urban/storm runoff, submarine groundwater discharge, etc) on Long Island, nor clear understanding about the host organisms from which they originate (such as human, mammals, or birds). Pathogen loads to specific embayments are affected by watershed land-use,...
Coastal planners and resources managers require information about potential future climate and land-use changes for nearshore areas, in terms that are relevant for the human and natural environments that are likely to be affected by climate change. The collection and synthesis of climate and climate-derived data sets, as well as, land-use and impervious-area data would allow practitioners to analyze and visualize a coastal area's potential impacts caused by future climate and land-use changes. The USGS studies climate and land-changes to provide the tools to understand a changing world and how it impacts our natural resources, our livelihoods, and our communities. Planners and resource managers use a variety of...
The NYWSC carries out multidisciplinary science activities across the State’s diverse coastal waters and landscapes on the Atlantic Ocean and the Great Lakes, including the many interconnected waterways, the barrier beaches that form and erode continually, the open waterways that are prone to the effects of major storms and hurricanes, and upland surface-water and groundwater source areas. These areas are also some of the most productive ecosystems in the State and host most of the population and economic development of the State. As a result, the interplay of environmental- and human-health concerns is a prominent thread that connects much of the coastal science activities of the USGS and involves cooperation not...
Coastal communities are uniquely vulnerable to sea-level rise (SLR) and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in coming years. The U.S. Geological Survey has developed a strategy to define baseline and post-event sediment-bound environmental health (EH) stress­ors (hereafter referred to as the Sediment-Bound Contaminant Resiliency and Response [SCoRR] strategy). A tiered, multi­metric approach has been developed to (1) identify and map contaminant sources and potential exposure pathways for human and ecological...

Hurricane Sandy has created three open breaches in the barrier island system along the south shore of Long Island, N.Y. In response, the National Park Service has sought assistance from the U.S. Geological Survey (USGS) New York Water Science Center (NYWSC) to help evaluate the open breach condition in Federal Wilderness near the Old Inlet area of Fire Island National Seashore, N.Y. The NYWSC evaluation is initially focusing on two activities: measurement of water velocities and depths within the Wilderness breach, and collection of water levels within Great South Bay (GSB) adjacent to the breach. Measurement of water velocities and depths within the Wilderness breach is being done with a Sontek 1 M9 acoustic...

Introduction Mosquitoes are the principle vector of the West Nile Virus (WNV) which causes infections in humans and animals and has emerged as a public health threat throughout Long Island, NY. The WNV was first detected among birds and mosquitoes by the Suffolk County Department of Health Services (SCDHS) in 2000. In response to the public health concern, the USGS in cooperation with the SCDHS, began a 3-year study in 2002 to sample surface waters in selected wetlands for insecticides which were sprayed seasonally from a truck or helicopter as part of the county's vector-control program. These insecticides include Altosid (methoprene) and Scourge [1:3 ratio of resmethrin and piperonyl butoxide (PBO)]. Methoprene...

Problem Dissolved oxygen (DO) is an important indicator of water quality that until recently has been cost-prohibitive to monitor extensively in both space and time. Continuous water-quality data, particularly in coastal environments with bidirectional tidal flow, is necessary for resource managers to understand the dynamic changes in water quality that occur tidally, daily, seasonally, and during aperiodic events. In the estuaries surrounding Long Island, such events may include wastewater treatment plant failures, harmful algal blooms, and extreme weather. The U.S. Geological Survey (USGS) has extensive experience with continuous water-quality monitoring at fixed locations along the coast that provides valuable...
