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.

Genomic and Behavioral Effects of the Neonicotinoid Imidacloprid in Birds Exposed Through Pesticide-Coated Seeds

The Challenge: Neonicotinoid pesticides act as agonists of nicotinic acetylcholine receptors (nAChRs) and are designed to be lethal to insects while theoretically posing little to no threat to vertebrates. The perceived safety of neonicotinoids has led to a sharp increase in their use in the United States and globally, since they were first introduced in 1994. The use of the neonicotinoid...

U.S. Geological Survey (USGS) Science Summary—The Role of Storms on Bank Erosion Rates and Sediment Transport in Urban Areas

Sediment is a major pollutant degrading aquatic ecosystems in the Chesapeake Bay watershed. The USGS is conducting studies to determine the relative importance of streambank erosion to other sediment sources, such as upland erosion, in both agricultural and urban areas. The information is necessary so resource managers can focus on the types, and locations, of practices that will be most...

National Assessment of Coastal Vulnerability to Sea Level Rise

The original national coastal vulnerability index (CVI) assessment was motivated by expected accelerated sea-level rise (SLR) and the uncertainty in the response of the coastline to SLR. This research was conducted between 1999 and 2001, and is currently being updated using new data sources and methodology. This original study was part of the ...

Chesapeake Bay ‘dead zone’ to vary from average to slightly smaller

Hypoxic zone size affected by low river flow and nutrient loading

Scientists expect that this year’s mid-summer Chesapeake Bay hypoxic low-oxygen zone or “dead zone” – an area of low to no oxygen that can kill fish and aquatic life – will be approximately 1.58 cubic miles, about the volume of 2.3 million Olympic-size swimming pools. This is close to the long-term...

Streamflow in the Watershed and Entering the Chesapeake Bay

The health of the Chesapeake Bay, and streams in the watershed, are affected by changes in surface-water flows. Runoff from storms carries pollutants, such as nutrients, sediments, and toxic contaminants, into streams throughout the 64,000 square-mile watershed, which drain to the Bay. The changes of stream flow, and associated pollutant loads, influence habitat conditions for fisheries and...

Shaken, Not Stirred--3.6 Earthquake in Maryland

This morning the Washington D.C. Metro area was awakened by a 3.6 magnitude earthquake which struck near Germantown, Maryland and was widely felt throughout the region. We spoke with Mike Blanpied, of our Earthquake Hazards Program, about the details related to this event, why it was felt so widely, and what people can do to prepare around the region.
