Research / Professional Focus / Current Projects
In my role as Data Chief, and supervisor of the Data Section of the MD-DE-DC Water Science Center, my interests encompass all aspects of USGS water-data collection, interpretation, and publication activities in Maryland, Delaware, and the District of Columbia.
I support and maintain appropriate staff to achieve the Center's data-collection commitments, and facilitate the effective and efficient performance of data-collection work tasks that are focused and aligned with the USGS mission as well as local and regional partners' water-resource data and analysis needs.

MD-DE-DC WSC Water Use & Water Supply Capabilities
In Maryland, public supply water is delivered to users for domestic, commercial, and industrial purposes. Most is used for public services, such as public pools, parks, firefighting, water and wastewater treatment, and municipal buildings, and some is unaccounted for because of leaks, flushing, tower maintenance, and other system losses. 5.7 million Marylanders get their water from the public...

MD-DE-DC Water Quality Capabilities
Water quality is a measure of the suitability of water for a particular use based on selected physical, chemical, and biological characteristics. Water-quality monitoring is used to help water-resource managers understand and avert potential negative effects of man-made and natural stresses on water resources, evaluate trends, and compare to water-quality criteria.
One of our primary...
Next Generation Water Observing System: Delaware River Basin
The USGS Next Generation Water Observing System will provide high-fidelity, real-time data on water quantity and quality necessary to support modern water prediction and decision support systems for water emergencies and daily water operations. The Delaware River Basin pilot provides an opportunity to develop the NextGen observing system in a nationally important, complex interstate river...
Coastal Monitoring Tide Gage Sites in Maryland, Delaware, and Washington, D.C.
Vital coastal storm-tide information needed to help guide storm response efforts following major storms affecting Maryland will be more accessible than ever due to a new monitoring network the U.S. Geological Survey is currently building.
A team from the USGS MD-DE-DC Water Science Center is surveying 63 locations in the state, determining their elevations and installing receiving...
Forage and habitat for pollinators in the northern Great Plains—Implications for U.S. Department of Agriculture conservation programs
Managed and wild pollinators are critical components of agricultural and natural systems. Despite the well-known value of insect pollinators to U.S. agriculture, Apis mellifera (Linnaeus, 1758; honey bees) and wild bees currently face numerous stressors that have resulted in declining health. These declines have engendered support for pollinator...

Sediment lithology and borehole erosion testing, American and Sacramento Rivers, California
Executive SummaryA field investigation intended to measure the potential for erosion of sediments beside the American and Sacramento Rivers near Sacramento, California, is described. The study featured two primary components: (1) drilling and soil sampling to reveal lithology, down to depths matching the local river thalweg, where possible, and (2...

International geoscience collaboration to support critical mineral discovery
The importance of critical minerals and the need to expand and diversify critical mineral supply chains has been endorsed by the Federal governments of Australia, Canada, and the United States. The geoscience organizations of Geoscience Australia, the Geological Survey of Canada and the U.S. Geological Survey have created the Critical Minerals...

Effects of stormwater runoff from selected bridge decks on conditions of water, sediment, and biological quality in receiving waters in South Carolina, 2013 to 2018
The U.S. Geological Survey, in cooperation with the South Carolina Department of Transportation, investigated the effects of stormwater runoff from bridge decks on stream water quality conditions in South Carolina. The investigation assessed 5 bridges in 3 physiographic provinces in South Carolina (Piedmont, Upper Coastal Plain, and Lower Coast...

Segmentation and supercycles: A catalog of earthquake rupture patterns from the Sumatran Sunda Megathrust and other well-studied faults worldwide
After more than 100 years of earthquake research, earthquake forecasting, which relies on knowledge of past fault rupture patterns, has become the foundation for societal defense against seismic natural disasters. A concept that has come into focus more recently is that rupture segmentation and cyclicity can be complex, and that a characteristic...
Philibosian, Belle; Meltzner, Aron J. Assessing nest attentiveness of Common Terns via video cameras and temperature loggers
While nest attentiveness plays a critical role in the reproductive success of avian species, little nest attentiveness data with high temporal resolution is available for many species. However, improvements in both video monitoring and temperature logging devices present an opportunity to improve our understanding of this aspect of avian behavior...

Development of a two-stage life cycle model for Oncorhynchus kisutch (coho salmon) in the upper Cowlitz River Basin, Washington
Recovery of salmon populations in the upper Cowlitz River Basin depends on trap-and-haul efforts owing to impassable dams. Therefore, successful recovery depends on the collection of out-migrating juvenile salmon at Cowlitz Falls Dam (CFD) for transport below downstream dams, as well as the collection of adults for transport upstream from the dams...

The effects of management practices on grassland birds—Savannah Sparrow (Passerculus sandwichensis)
Keys to Savannah Sparrow (Passerculus sandwichensis) management are providing extensive grasslands of intermediate height and density with a well-developed litter layer, controlling succession, and protecting nesting habitat from disturbance during the breeding season. Savannah Sparrows have been reported to use habitats with 11–190 centimeters (...

Structure contour and overburden maps of the Niobrara interval of the Upper Cretaceous Cody Shale in the Bighorn Basin, Wyoming and Montana
The Bighorn Basin is a large intermontane sedimentary and structural basin that formed during the Laramide orogeny. The first commercial hydrocarbon production in the Bighorn Basin was established in 1906 from Cretaceous reservoirs at Garland field followed by the discovery of Greybull field in 1907. Since then, many important conventional...
Finn, Thomas M. Accidental chlorophacinone exposure of lactating ewes: Clinical follow-up and human health dietary implications
Anticoagulant rodenticides are widely used for rodent control in agricultural and urban settings. Their intense use can sometimes result in accidental exposure and even poisoning of livestock. Can milk, eggs or meat derived from such accidentally exposed animals be consumed by humans? Data on the pharmacokinetics of chlorophacinone in milk of...
Lefebvre, Sébastien; Fourel, Isabelle; Benoit, Etienne; Rattner, Barnett A.; Lattard, Virginie; Moriceau, Meg-Anne; Lefebvre, Sébastien; Fourel, Isabelle; Benoit, Etienne; Rattner, Barnett A.; Lattard, Virginie Validating deployment of aerially delivered toxic bait cartridges for control of invasive brown rreesnakes
Aerial application of management tools can provide a cost‐effective means to conserve or control wildlife populations at the landscape scale. Large spatial scales, however, present difficulties when assessing in situ reliability and integrity of the devices themselves. We demonstrate application of a distance‐sampling density estimation approach...
