One of the major strengths of the Northeast Area is the enthusiasm and commitment of our scientists to produce the type of high quality science that the USGS is known for. Working together with our partners across the nation, we have the ability to provide complete, integrated and holistic environmental information that will produce the best results that we can achieve.
The Challenge: The genomic revolution is giving wildlife biologists new tools to assess the role of wildlife in spreading diseases that affect human populations. Peptide arrays are a high throughput technology that gives unprecedented breadth and depth of information about the immune system. We are using peptide arrays to assess the immune responses of Chesapeake Bay waterfowl to avian...
The Challenge: In an era when emerging infectious diseases are steadily increasing, human populations are exposed to virulent new pathogens. Insight into the human system can be gained from understanding the variety of immune adaptations of wildlife species. The vertebrate immune system is not static. Rather, it involves in response to the environment.
Sustainably Designed Trails: Recent Recreation Ecology Findings on Design Factors Affecting Soil Loss
The Challenge: Achieving conservation objectives in protected natural areas requires the ability to sustain visitation while avoiding or minimizing adverse environmental impacts. Trails are an essential infrastructure component that limits resource impacts by concentrating use on hardened treads designed and maintained to sustain traffic. This is particularly challenging when visitation is...
The Challenge: Climate change and sea level rise are expected to affect many miles of shoreline in the Chesapeake Bay and elsewhere along the Atlantic Coast in the coming years. In this scenario, federal and state agencies need to make more detailed assessments of how different watersheds and shoreline types might influence an array of ecosystem functions and components. Recently, most states...
The Challenge: In eastern North America there is a viral disease called Eastern Equine Encephalitis, or EEE. This virus is transmitted among native bird species by the mosquito, Culiseta melanura, but does not cause disease in these passerine species. However, the virus is capable of causing severe disease or death in horses, some game bird species, humans and whooping cranes. In the fall of...
Use of Structured Decision Making to Optimize Salt Marsh Management Decisions at Northeastern National Wildlife Refuges
The Challenge: The U.S. Fish and Wildlife Service (FWS) needs tools to inform decisions regarding the management and restoration of salt marsh ecosystems on northeastern National Wildlife Refuges. Previously, we developed a structured decision making (SDM) framework for optimizing refuge management decisions. This SDM framework served as the foundation for FWS to implement a consistent...
The Challenge: In December of 2014, a novel strain of highly pathogenic avian influenza (HPAI) caused an outbreak in poultry on the West coast of the United States. From there, the virus progressed steadily eastward, causing $3.3 billion in economic losses in addition to 50 million chickens or turkeys dying or being depopulated. While the primary mode of spread appears to be via the poultry...
The Challenge: The proliferation and degradation of visitor-created “informal” trails in protected areas can be a vexing management issue for land managers. Formal trail systems never provide access to all locations required by visitors seeking to engage in a variety of appropriate recreational activities. Traveling off-trail may be necessary to engage in activities such as nature study,...
The Challenge: A number of coastal states have been altering marshes for mosquito control since the early 1900s, but for the past four decades, changes have been made in the methods used to alter high-marsh environments. However, in most states, research and monitoring activities are still needed to inform the management methods employed. Although modern Open Marsh Water Management (OMWM)...
The Challenge: Changes in aquatic ecosystems related to climate change phenomena or other anthropogenically based environmental stressors have significant impact on the dynamics of the host-pathogen-environment relationship, often with surprising results. Therefore, biosurveillance of the aquatic environment for pathogens of significance to aquatic and terrestrial wildlife, as well as to...
The Challenge: Following outbreaks of highly pathogenic avian influenza (HPAI) in Eurasia, many researchers have attempted to determine how this virus spreads across the landscape. Unfortunately, prior to this work, most studies on HPAI movements were based on virology data alone, and no information on host ecology. Beginning in 2007, USGS Patuxent Wildlife Research Center (PWRC) and Western...
The Challenge: Highly pathogenic avian influenza viruses (HPAI) of certain subtypes primarily infect poultry, causing disease outbreaks and negative socio-economic impacts on poultry farming depending on the characteristics of biosecurity and the virus strain. HPAI viruses seem to be adapted to artificial ecosystems including poultry farming, free-ranging duck production, and live bird markets...

Evaluation and application of regional turbidity-sediment regression models in Virginia
Conventional thinking has long held that turbidity-sediment surrogate-regression equations are site specific and that regression equations developed at a single monitoring station should not be applied to another station; however, few studies have evaluated this issue in a rigorous manner. If robust regional turbidity-sediment models can be...Hyer, Kenneth; Jastram, John D.; Moyer, Douglas; Webber, James S.; Chanat, Jeffrey G.

The Marcellus Shale gas field underlies portions of New York, Pennsylvania, Ohio, Virginia, Maryland, Tennessee, and West Virginia. Development of hydraulic fracturing and horizontal drilling technology led to extensive development of gas from the Marcellus Shale beginning about 2007. The need to identify and monitor changes in water-quality...Chambers, Douglas B.; Kozar, Mark D.; Messinger, Terence; Mulder, Michon L.; Pelak, Adam J.; White , Jeremy S.

Assessing the magnitude and timing of anthropogenic warming of a shallow aquifer: example from Virginia Beach, USA
Groundwater temperature measurements in a shallow coastal aquifer in Virginia Beach, Virginia, USA, suggest groundwater warming of +4.1 °C relative to deeper geothermal gradients. Observed warming is related to timing and depth of influence of two potential thermal drivers—atmospheric temperature increases and urbanization. Results...Eggleston, John R.; McCoy, Kurt J.

Monitoring Roanoke River along Route 626 at Lafayette, VA
Monitoring Spruce Creek at Route 627 near Nellysford, VA
A large outbreak of gypsy moth (Lymantria dispar) caterpillars attacked the hardwood forests of the northeastern United States in 2016. A fungus (Entomophaga maimaigaM) introduced from Japan has kept gypsy moth populations at relatively low levels since the late 1980s. However, abnormally low rainfall during May and June in 2014, 2015, and 2016 reduced...

The USGS National Minerals Information Center tracks how much the United States relies on other countries for minerals critical to the economy and national security.
Florida’s iconic manatee population is highly likely to endure for the next 100 years, so long as wildlife managers continue to protect the marine mammals and their habitat, a new study by the US Geological Survey and the Florida Fish and Wildlife Research Institute has found.
In 2016, the United States mined $74.6 billion worth of minerals, and the following five mineral commodities accounted for 68.5 percent of that value.
New USGS assessment provides fresh insights into nation’s brackish groundwater inventory
U.S. Geological Survey scientist emeritus Chandler S. Robbins, whose heartfelt love of birds, quicksilver mind, boundless energy and sunny demeanor made him a major force in bird conservation in the U.S. and worldwide, died Monday, March 20 at the age of 98.
Tests of 75 private drinking water wells in Lycoming County, in north-central Pennsylvania, found water from most of the sampled wells contained concentrations of radon that exceeded a proposed, nonbinding health standard for drinking water. Smaller percentages of the wells contained concentrations of arsenic or methane that exceed existing drinking water standards.
Philadelphia communities along the Schuylkill River and Darby Creek now have new tools to help inform residents of impending flooding. The U.S. Geological Survey recently installed three new streamgages in Manayunk, Eastwick, and downtown near 30th St., which will monitor water levels, and provide vital data used by emergency managers and flood forecasters to help protect lives and property.
