South Shore Estuary Reserve Total Maximum Daily Load Monitoring

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...

Water Resources of Monroe County, New York

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...

Mercury Bioaccumulation in Fish in New York's Streams and Rivers

Background Although New York State has more than 70,000 miles of streams and rivers, little is known about the status, distribution, and trends of mercury (Hg) levels in stream fish, or the environmental drivers of these patterns. Streams and their riparian zones provide critical habitat for fish, birds, mammals, reptiles and amphibians, and serve as the interface between aquatic and...

Assessment of Acidic Deposition Effects on the Chemistry and Benthos of Streams of the East-Central Adirondack Region

Project Summary. The Western Adirondack Stream Survey (WASS), conducted in 2003-2005, showed that acidic deposition was causing toxic forms of Al to move from soils to streams in 66% of the 565 watersheds assessed in the study region. The WASS encompassed only 20% of the Adirondack region, and for the remaining 80% (referred to hereafter as the East-Central Adirondack region), there is l...

Adirondack Long-Term Stream and Soil Monitoring

The current Adirondack Long-Term Monitoring Program combines monitoring of streams and soils based on a watershed design. Not only are headwater streams an important component of Adirondack ecosystems, they are closely tied to the terrestrial environment through runoff that is strongly influenced by soil and vegetation processes. This linkage makes headwater streams a useful tool for monitor...

Effects of acid rain on the ecological health of Long Island’s forests and ponds

BACKGROUND Air emissions from the combustion of fossil fuels in electrical power plants, building heating systems and vehicles are the major source of gaseous sulfur (SOx) and nitrogen (NOx) oxides in the atmosphere. These oxides dissolve in atmospheric moisture forming ions which are deposited by rain, snowfall and dust particles as acidic deposition. Acidic deposition releases soluble...

Development of a Graphical User Interface (GUI) to Predict Streamflow Statistics using USGS Streamstats and Precipitation from Downscaled Global Climate Change Models

Background Climate change during the past century has resulted in changes to precipitation amounts, form (rain vs. snow), as well as frequency and intensity in the northeastern US (Huntington et al., 2009). Additional changes in precipitation are forecast for the 21st Century as the global and regional climate is expected to warm substantially (Hayhoe et al., 2007). These ongoing and proje...

Effects of flow alteration on ecological health of streams across the Atlantic Highlands Ecoregion

Problem: The Clean Water Act (PL 92-500) requires that the health of the Nation’s rivers and streams be assessed on a regular basis, and in the Northeast such assessments often use information from aquatic biological communities that live in the stream. Biomonitoring programs implemented by individual states evaluate biological data to assess stream health on the premise that certain...

Canopy volume removal from oil and gas development activity in the upper Susquehanna River basin in Pennsylvania and New York (USA): An assessment using lidar data

Oil and gas development is changing the landscape in many regions of the United States and globally. However, the nature, extent, and magnitude of landscape change and development, and precisely how this development compares to other ongoing land conversion (e.g. urban/sub-urban development, timber harvest) is not well understood.

Carboniferous climate teleconnections archived in coupled bioapatite δ18OPO4 and 87Sr/86Sr records from the epicontinental Donets Basin, Ukraine

Reconstructions of paleo-seawater chemistry are largely inferred from biogenic records of epicontinental seas. Recent studies provide considerable evidence for large-scale spatial and temporal variability in the environmental dynamics of these semi-restricted seas that leads to the decoupling of epicontinental isotopic records from those of the...
