Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Regions L2 Landing Page Tabs

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.

Integrating Habitat and Harvest Management for Northern Pintails

The Challenge: Several blue-ribbon panels have challenged the waterfowl management world to recognize the linkages between the two primary management frameworks: harvest management under the Migratory Bird Treaty Act, and habitat management under the North American Waterfowl Management Plan. Because these two frameworks seek to manage the same populations, there needs to be better coordination...

Modeling, Estimation, and Adaptive Management of Florida Manatees

The Challenge: Florida manatees are threatened by watercraft-related mortality, the potential loss of warmwater habitat, red tide events, and other anthropogenic factors. The USFWS and the Florida Fish and Wildlife Conservation Commission have regulatory authorities under the Endangered Species Act (ESA), the Marine Mammal Protection Act (MMPA), and state statutes to recover manatees. To...

Adaptive Management for Threatened and Endangered Species

The Challenge: Threatened and endangered species have to be managed in the face of uncertainty, but traditionally, there has been reluctance to think about adaptive management of listed species. Management agencies with responsibility for threatened and endangered species need tools to help manage in the face of uncertainty, with the hope of reducing that uncertainty.

Structured Decision Making: Methods, Applications, and Capacity-Building

The Challenge: The field of decision analysis is a rich and mature discipline that provides robust methods for helping decision makers understand the nature of their decisions, involve stakeholders and scientists in appropriate steps of the process, and develop transparent records for the public. The use of these structured approaches is emerging in natural resource management, and there is...

Study Shows High Potential for Groundwater to be Corrosive in Half of U.S. States

A new U.S. Geological Survey assessment of more than 20,000 wells nationwide shows that untreated groundwater in 25 states has a high prevalence of being potentially corrosive. The states with the largest percentage of wells with potentially corrosive groundwater are located primarily in the Northeast, the Southeast, and the Northwest.

The North American Breeding Bird Survey: Refining Scale to Provide New Insights

The Challenge: Since 1966, the North American Breeding Bird Survey (BBS) has filled a vital role in identifying at-risk bird species for Federal, State, and private entities. The BBS is a scientifically rigorous population count performed by a highly skilled, largely volunteer work force of nearly 2,500 observers. Every year these observers visit most of the survey’s 4,500 routes, which...

Native Bee Status and Vulnerability to Climate Change in National Parks

The Challenge: Mountain tops and Coastal Dunes - These are perhaps the most vulnerable locations in the United States to climate change in the lower 48 states. Native bees also face challenges due to loss of the plants, from which they gather nectar and pollen, and from introduced diseases and general loss of habitat. Additionally, both Mountain Tops and Dunes contain bees that are only found...

Improving Our Ability to Forecast Tidal Marsh Response to Sea Level Rise

The Challenge: Accelerations in sea-level rise and changing environmental stressors have important implications for the integrity of coastal wetlands and for efforts to restore and protect the ecosystem services they provide. Their persistence and adaptation to these stressors depends on the net effects of changes in physical processes and biotic responses. Future planning by decision makers...

Contaminant Exposure, Food Web Transfer and Potential Health Effects on Chesapeake Bay and Delaware Bay Waterbirds

The Challenge: Agricultural, industrial and urban activities have had major effects on waterbirds in Chesapeake and Delaware Bays. Some legacy pollutants (PCBs, organochlorine pesticides, flame retardants, metals) pose a potential threat to wildlife in some locations. Pharmaceuticals, personal care products, and endocrine disrupting compounds have been detected in water and fish tissue, yet...

Hazard, Risk and Physiologically-based Pharmacokinetic Model for Anticoagulant Rodenticides in Kestrels and Owls

The Challenge: Anticoagulant rodenticides have been identified as being hazardous to predatory and scavenging birds on a global scale. Restrictions on the sale, distribution and packaging of some second generation anticoagulant rodenticides (e.g., brodifacoum, difethialone, bromadiolone and difenacoum) have been instituted by the US EPA, and will likely result in expanded use of first-...

Toxicity of the Non-Steroidal Anti-Inflammatory Drug Diclofenac

The Challenge: Diclofenac is a non-steroidal anti-inflammatory drug that has been used by veterinarians for the treatment of inflammation, fever and pain in domestic livestock. This drug appears to have been the principal cause of a severe population crash of vultures of the genus Gyps in India and Pakistan. Vultures unintentionally ingested diclofenac when scavenging livestock treated shortly...

Barre Granite

Granite is an igneous rock that we’ve used for building materials for thousands of years. It’s name comes from the Latin word “granum,” meaning “grain,” which refers to the grains of quartz and feldspar that define granite. This one is from the Barre formation in Vermont.

Cannel Coal

Cannel coal is a type of bituminous coal, which is the second-highest rank of coal (just behind anthracite). This particular sample has a high carbon content with high pollen and spore content as well. Unlike most bituminous coal, Cannel coal can be carved into ornaments. This sample came from the Eastern Interior Coalfield in Kentucky.
