Landslide Monitoring and Research in the Atlantic Highlands area, New Jersey

Recent shallow landslides have occurred on the steep hillslopes of the Atlantic Highlands area during and after large storm events with exceptionally heavy rainfall. These shallow landslides have resulted in extensive damage to residential property and local infrastructure and threatened human safety.The USGS New Jersey Water Science Center (NJWSC) and the USGS Landslide Hazards...

Hydrologic Monitoring and Analysis to Support Water Resource Management in the City of Roanoke

The U.S. Geological Survey, partnering with the City of Roanoke and Virginia Tech, are working to monitor the water volume and quality in streams throughout the City of Roanoke. There are currently six monitoring stations within the city. Water-quality data are collected at five stations through real-time monitors and manual sampling to support the estimation of suspended sediment loads. The...

Improving Time of Concentration Estimates for Small Rural Watersheds in the Appalachian Plateaus Physiographic Province, West Virginia

Many culverts and other drainage structures in rural West Virginia are located in small streams or valleys draining 100 acres or less. Design of these structures in West Virginia is generally done using discharge estimates made with widely used and well accepted methods. However, these methods require information including flow-segment length and channel geometry that are poorly characterized...

Responses of fish assemblages to changing environmental conditions in the Neversink River and Rondout Creek

Problem The Neversink River and Rondout Creek are historic trout fishing and recreational streams in the heart of the Catskill Mountains of southeastern NY. Waters throughout upper reaches of both rivers currently range from neutral to severely acidic due to deposition of acid rain throughout their watersheds. Fish surveys conducted by the USGS during the late 1980s and early 1990s found that...

Using Microbial Source Tracking to Identify Pollution Sources in Pathogen Impaired Embayments in Long Island, New York

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...

Long Island - Location and Physical Setting

Long Island, the eastern-most part of New York State, extends east-northeastward roughly parallel to the Connecticut coastline. It is bounded on the north by Long Island Sound, on the east and south by the Atlantic Ocean, and on the west by New York Bay and the East River. Long Island is joined to the mainland specifically, to the Borough of the Bronx, which is one of the five boroughs of New...

Long Island Topography

The present landforms of Long Island are the result of many geologic processes, some of which began many millions of years ago and some of which began only recently. Most of the major features of the present-day topography, however, are related to the last glaciation, which ended approximately 22,000 years ago.

Long Island Land Use and Land Cover

On Long Island, land use includes the human activities and management practices for which land is used. Land cover is a mosaic of developed, forest, agriculture, and wetlands areas. Both land use and land cover are usually discussed in similar environments. The National Land Cover Database (NLCD) serves as the definitive LANDSAT-based, 30-meter resolution, land cover database for the Nation....

Long Island Freshwater

Long Island is surrounded by an almost limitless amount of saltwater in the Atlantic Ocean, in the Long Island Sound, and in the many bays bordering Long Island. Although the salty water is important to the economy of the area and is of significant recreational value, this website is mainly concerned with the fresh water of Long Island, which from many standpoints, is even more important than...

Hydrologic Cycle

The water cycle has no starting point, but we'll begin in the oceans, since that is where most of Earth's water exists. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air; a relatively smaller amount of moisture is added as ice and snow sublimate directly from the solid state into vapor. Rising air currents take the vapor up into the ...

Long Island Precipitation and Recharge

Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain. 

Water seeping down from the land surface and reaching the water table adds to the groundwater and is called groundwater recharge....

Landscape evolution of a fluvial sediment-rich Avicennia marina mangrove forest: Insights from seasonal and inter-annual surface-elevation dynamics

Mangrove forests are vulnerable to accelerated sea-level rise associated with climate warming because they occupy a relatively narrow zone on the mid-to-upper-intertidal flats. The fate of these ecosystems largely depends on their capacity to accrete sediment at a rate sufficient to maintain their elevation relative to sea level. We investigated...

Demographic and genetic description of Greenland’s only indigenous Atlantic salmon Salmo salar population

A survey of the Kapisillit River system was conducted in 2005 and 2012 to study the only indigenous Atlantic salmon Salmo salar population in Greenland. Little is known about its characteristics or its relationship with other S. salar populations across the species range. Juvenile S. salar were captured in all stations surveyed within the lower...

Use of blood clotting assays to assess potential anticoagulant rodenticide exposure and effects in free-ranging birds of prey

Non-target wildlife, particularly birds of prey, are widely exposed to and acutely poisoned by anticoagulant rodenticides (ARs). An unresolved issue surrounding such exposure, however, is the potential for sublethal effects. In particular, the consequences of AR exposure and resulting coagulopathy on health and survival of...

The planktonic foraminiferal response to the Paleocene-Eocene thermal maximum on the Atlantic coastal plain

Planktonic foraminiferal assemblages in two cores from Maryland and New Jersey show evidence for significant changes in surface ocean habitats on the continental shelf during the Paleocene-Eocene Thermal Maximum (PETM). At both sites, significant assemblage shifts occur immediately before the onset of the event. These changes...

Estimating occurrence, prevalence, and detection of amphibian pathogens: Insights from occupancy models

Understanding the distribution of pathogens across landscapes and their prevalence within host populations is a common aim of wildlife managers. Despite the need for unbiased estimates of pathogen occurrence and prevalence for planning effective management interventions, many researchers fail to account for imperfect pathogen detection. Instead...

Salt marsh ecosystem restructuring enhances elevation resilience and carbon storage during accelerating relative sea-level rise

Salt marshes respond to sea-level rise through a series of complex and dynamic bio-physical feedbacks. In this study, we found that sea-level rise triggered salt marsh habitat restructuring, with the associated vegetation changes enhancing salt marsh elevation resilience. A continuous record of marsh elevation...

A preliminary assessment of hyperspectral remote sensing technology for mapping submerged aquatic vegetation in the Upper Delaware River National Parks

Hyperspectral remote sensing of submerged aquatic vegetation is a complex and difficult process that is affected by unique constraints on the energy flow profile near and below the water surface. In addition, shallow, winding, lotic systems, such as the Upper Delaware River, present additional remote sensing problems in the form of specular...

This study compares six immunological elements in eggs of six species within the same family, the...
