Geology and Sediment Availability - Coastal System Change at Fire Island, New York
Sediment supply is a critical control on barrier island vulnerability and resilience over a variety of time scales (e.g., storms to sea level rise). Past work at Fire Island and elsewhere has demonstrated a link between inner shelf sediment availability and barrier island evolution over geologic and historical time scales. However, there have been few opportunities to explore nearshore...
Long-Term Change - Coastal System Change at Fire Island, New York
Long-term coastal change can occur over historical (10s to 100s years) and geological time scales (100s-1000s years). At Fire Island, the historical record of the position of the island goes back to the 1800s. Changes since then are quantified using historical maps, aerial photos, and modern coastal mapping techniques.
Contaminants in fish tissues from AOCs in New York State: The Niagara River AOC
DEC collaborators collect fish from a Niagara River tributary using an electrofishing boat The New York State Department of Environmental Conservation (NYSDEC) and Department of Health (NYSDOH), and the U.S. Geological Survey (USGS) are gathering data on chemical contaminants in fish from multiple Areas of Concern (AOCs) in New York State and plan to use this information to evaluate fish cons...
River Continuum Concept Ecological Limit Functions for Fish and Benthic Data in Virginia
The ecological limit functions (ELF) developed in cooperation with the Virginia Department of Environmental Quality (DEQ) are a graphical representation of the current and historical state of aquatic biota in Virginia streams. The goal of this study was to quantify the potential species richness and habitat response to flow alteration using available long-term ecological data. Fish and...
Morphological Behavior - Coastal System Change at Fire Island, New York
Sand is constantly exchanged between beaches, dunes, and the submerged shoreface, which includes the nearshore sand bar system. We use specialized vessels and equipment to understand the feedbacks between nearshore morphology changes and coastal change to improve predictions of future impacts.
Open Ocean/Marine - Coastal System Change at Fire Island, New York
Geophysical mapping and research have demonstrated that the seabed on the inner continental shelf has a variety of shapes which are linked to long-term evolution of the barrier island. Regional-scale modeling forecasts how atmospheric forcing and oceanographic circulation case sand, gravel, and other materials to be transported by tides, winds, waves, fresh water fluxes, and density variations...
Nearshore - Coastal System Change at Fire Island, New York
The nearshore is the submerged portion of the shoreface between the inner shelf and the shoreline and includes the surf zone, where waves break. Along with beaches and dunes, nearshore morphology and geology adjusts to changes in waves, sediment supply, human alterations, and sea level rise. By measuring nearshore morphologic and geologic variations, we can understand how quickly beaches and...
New England WSC Seminar series Simeone 20190424
Forest cover is predicted to decline in the western US in the next century, due in part to increased hydraulic stress associated with climate change. There has been a large body of work done on adult trees in natural settings, but a smaller amount has been done on more vulnerable seedlings outside of the greenhouse.
Upper Esopus Creek Tributary Bedload Pilot Study
Problem Sediment transport is a serious concern in the upper Esopus Creek watershed. The creek is a well-documented source of sediment and turbidity to the Ashokan Reservoir, which is part of the New York City water supply system. During the last 2 decades there has been a series of stream stabilization and sediment reduction projects completed in the upper Esopus Creek watershed intended to...
United States Assessments of Undiscovered Oil and Gas Resources

Edge-of-field monitoring
Edge-of-field monitoring focuses on identifying and reducing agricultural sources of excess nutrients which can threaten the health of streams, rivers, and lakes. Edge-of-field monitoring assesses the quantity and quality of agricultural runoff and evaluates the effectiveness of conservation practices that aim to reduce nutrient loss.
Using optical sensors to detect sewage contamination in the Great Lakes
In the Great Lakes, large volumes of sewage never make it to wastewater treatment plants due to illicit discharges and leaking sewer infrastructure, but contamination can be difficult to detect. This study will define the utility and practicality of using optical sensors to identify the sources and timing of sewage contamination in surface water and storm sewers in real-time field settings....
WaterWatch is a U.S. Geological Survey (USGS) World Wide Web site that displays maps, graphs, and tables describing real-time, recent, and past streamflow conditions for the United States.Â
The data collected in this study will aid research on the ecology of fish and invertebrate species that inhabit the region. On August 22 and 23, 2017, the U.S. Geological Survey, in collaboration with the Stellwagen Bank National Marine Sanctuary, conducted a research cruise aboard the Sanctuary’s Research Vessel Auk, visiting 39 locations within the sanctuary.Â

Morphodynamic modeling of the response of two barrier islands to Atlantic hurricane forcing
The accurate prediction of a barrier island response to storms is challenging because of the complex interaction between hydro- and morphodynamic processes that changes at different stages during an event. Assessment of the predictive skill is further complicated because of uncertainty in the hydraulic forcing, initial conditions, and the...

Water for Long Island: Now and for the future
Do you ever wonder where your water comes from? If you live in Nassau or Suffolk County, the answer is, groundwater. Groundwater is water that started out as precipitation (rain and snow melt) and seeped into the ground. This seepage recharges the freshwater stored underground, in the spaces between the grains of sand and gravel in what are...

Lathrop, Timothy R.; Bunch, Aubrey R.; Downhour, Myles S.; Perkins, Daniel M. Deer do not affect short-term rates of vegetation recovery in overwash fans on Fire Island after Hurricane Sandy
1. Coastal resilience is threatened as storm-induced disturbances become more frequent and intense with anticipated changes in weather patterns. After severe storms, rapid recovery of vegetation, especially that of dune-stabilizing plants, is a fundamental property of coastal resilience. Herbivores may affect resilience by selectively foraging...
Kilheffer, Chellby R.; Underwood, H. Brian; Raphael, Jordan; Ries, Lindsay; Farrell, Shannon; Leopold, Donald J. Decline of the North American avifauna
Species extinctions have defined the global biodiversity crisis, but extinction begins with loss in abundance of organisms that can result in extreme compositional and functional changes of ecosystems.

Ottinger, Christopher A.; Smith, Cheyenne R; Blazer, Vicki S. Permeability anisotropy and relative permeability in sediments from the National Gas Hydrate Program Expedition 02, offshore India
Gas and water permeability through hydrate-bearing sediments essentially governs the economic feasibility of gas production from gas hydrate deposits. Characterizing a reservoir’s permeability can be difficult because even collocated permeability measurements can vary by 4-5 orders of magnitude, due partly to differences between how various...

USGS Tests drone-based ground-penetrating radar for bathymetry
USGS hydrographers collect tens of thousands of streamflow measurements every year. In-water work by personnel is one of the most dangerous aspects of USGS hydrologic studies, especially during high-flow conditions. In May 2019, USGS continued testing of a light-weight, self-contained ground-penetrating radar (GPR) system that can be mounted on a small drone. We are
