Unified Interior Regions
Maryland
Maryland's water supply comes from streams, rivers, groundwater and reservoirs. Many of these systems flow to the Chesapeake Bay, the Nation's largest estuary. This complex ecosystem has been degraded due to the impact of human-population increase. The MD-DC-DE Water Science Center studies the impacts this has on water quality, habitats and biological communities.

Endocrine Active Effects on Turtle Embryonic Development
The Challenge: Emerging contaminants may be in part responsible for recent endocrine disruption observed in fish in the Chesapeake Bay watershed. Endocrine active compounds implicated in the decline of fish populations may affect other wildlife as well. There are 6 species of turtles and 5 of snakes living within the main-stem and tidal areas of the Bay. As poikilotherms, reptiles are...
The Eastern Box Turtle at USGS Patuxent Wildlife Research Center, MD
The Challenge: Once common to forest and backyard habitats, the eastern box turtle (Terrapene carolina) has declined sharply. Threats to box turtles include loss and fragmentation of their habitat, road mortality, and commercial taking for the international pet trade. Researchers at the USGS Patuxent Wildlife Research Center have 70 years of records on a turtle population located within a 12...
West Coast Fish Pathogen Now Found in the East
Research by the USGS identified a fish pathogen similar to one previously found in the United States only in Pacific salmonids -- salmon and trout species -- in the eastern United States and in a non-salmon species.
HDgov: Multi-agency Website for Human Dimensions of Natural Resources
HDgov is an interactive and mobile-responsive online portal to interagency, academic, and non-government resources focused on the human dimensions of natural resource management. The web portal provides easy access to tools, publications, data, and methods that help ensure that the people side of natural resources is considered throughout the entire natural resource management process. The...
National Park Service Visitor Spending Effects
The National Park Service (NPS) manages the Nation’s most iconic destinations that attract millions of visitors from across the Nation and around the world. Trip-related spending by NPS visitors generates and supports a considerable amount of economic activity within park gateway communities. USGS economists collaborate with the National Park Service social science program to estimate NPS...
North American Waterfowl Management Plan
The ultimate success of North American Waterfowl Management Plan (NAWMP) depends on maintaining relevance to stakeholders and society. In order to be relevant, a first step is to better understand what people value in regard to waterfowl and their habitats.
Patuxent Library Services
The Patuxent Library provides reference services and support to the staff of the Patuxent Wildlife Research Center and also responds to inquiries from the general public. The collection focuses on birds, contaminants, monitoring, and wetlands as related to wildlife research.
Flood Science- Northeast Region Capability Team
One of the critical roles that USGS personnel play in their day-to-day activities is to respond in a timely and professional manner to floods that can occur at any time of the year and for a variety of reasons. The Flood Science Capability Team examines the cause and effect...
Understanding Coastal Change
Scientists perform a range of studies that document, assess, and model coastal change, risk, and vulnerability. Studies include historical shoreline change, the geologic structure and history of coastal regions, sediment supply and transport, sea-level rise, and how extreme storm events affect rates and impacts of coastal change.
Geologic Hazards and Catastrophic Events
We study the distribution and hazard potential of coastal and submarine events such as earthquakes and submarine landslides and associated tsunami potential, hurricane induced coastal inundation, extreme storms, sea-level rise and oil and gas spills. We also model development to help evaluate and forecast coastal hazard probability and occurrence.
Ocean Resources for America's Needs
Our scientists conduct research studies focused on geologic mapping, sampling and understanding of mineral and energy resources and studies of the geologic setting and processes to inform renewable energy development offshore.
Coastal and Marine Ecosystem Science
We bring together multidisciplinary expertise focused on developing tools and models to improve understanding of how healthy ecosystems function as well as how they respond to environmental changes and human impacts including ecosystem restoration. Research studies address coral reef, coastal wetland, benthic habitat and groundwater resources.
The "Best Report" for 2014 is "Hydrogeologic characterization and assessment of bioremediation of chlorinated benzenes and benzene in wetland areas, Standard Chlorine of Delaware, Inc. Superfund Site, New Castle County, Delaware, 2009-12"
Hydrogeologic characterization and assessment of bioremediation of chlorinated benzenes and benzene in wetland areasThe Chesapeake Bay is affected by multiple factors, ranging from population growth to climate variability, which will challenge the recovery of this important ecosystem.
For several years, scientists have been working to determine why so many male smallmouth bass in the Potomac River basin have immature female egg cells in their testes - a form of intersex. They are closer to finding an answer.
You are invited to attend an event co-hosted by The Embassy of Afghanistan and the Afghan-American Chamber of Commerce where the U.S. Geological Survey will unveil a 2007 preliminary assessment of non-fuel mineral resources of Afghanistan.
The discovery of a high incidence of intersex (male fish exhibiting female characteristics) in smallmouth bass of the Potomac River Basin has prompted an investigation of water quality and wastewater discharge into the upper Potomac, and blood-plasma studies on this fish species.
Many chemicals were detected in ground water from selected areas of the Piedmont Aquifer System (PAS), but concentrations of those chemicals were below drinking-water standards in most cases, according to a report released by the U.S. Geological Survey (USGS).
Many chemicals were detected in ground water from selected areas of the Piedmont Aquifer System (PAS), but concentrations of those chemicals were below drinking-water standards in most cases, according to a report released by the U.S. Geological Survey (USGS). For example, none of the 47 pesticides or 59 volatile organic compounds (VOCs) analyzed exceeded drinking-water standards.
A West Indian manatee has been sighted in various waters of the northeastern United States in the last 5-6 weeks. It took in the sights along the Hudson River traveling up into Harlem, visited Cape Cod, Mass., and was most recently sighted in Warwick, Rhode Island, in Greenwich Bay.
The U.S. Geological Survey (USGS) National Fish Health Research Laboratory and NOAA´s Cooperative Oxford Laboratory are cosponsoring a workshop on mycobacteriosis in Chesapeake Bay striped bass. This disease, also known as "fish-handlers disease," causes wasting and skin lesions in rockfish, a species that is important to recreational and commercial fishers and the economy of the Chesapeake Bay.

Despite recent rain, water levels in streams throughout the Mid-Atlantic and surrounding regions remain near record lows for this time of year, according to hydrologists at the U.S. Geological Survey (USGS).
