Contaminants and Environmental Pathways

Living things are intricately connected to each other and to the air, water, and soil that surrounds them. Our research looks at how contaminants move through the environment and living things to understand the chemical and physiological processes and ecological factors that influence exposure and risk in wildlife.

Freshwater

Our nation’s rivers have many uses. People have altered the flow of some rivers through diversions, dams, and water use.  Such changes can affect fish populations and our scientist work to understand these effects by answering such questions as “How is survival of young fish affected by streamflow patterns?” and “How do fish communities respond to changes in water management?”

Wind Energy

Demands for alternative energy are increasing and the number of wind farms, both terrestrial and in the marine environment, while serving great benefit to society, have the potential to impact wildlife populations, particularly birds and bats.  Studies of the spatio-temporal distribution and abundance of birds can identify sensitive and high–use areas in need of protection, not to mention...

Structured Decision Making

The biggest natural resource management challenges include competing views of the value and uses of those resources in society. Patuxent scientists develop methods to manage resources given those competing views under a “structured decision making” (SDM) framework. Our scientists both practice and train others in key SDM skills, such as model development and monitoring design.

Gas Hydrates- Climate and Hydrate Interactions

Breakdown of gas hydrates due to short- or long-term climate change may release methane to the ocean-atmosphere system. Methane that reaches the atmosphere can in turn exacerbate climate warming. Studies of methane hydrate dynamics and methane release on the continental shelf and upper slope in the US Arctic and Atlantic margin are tracking these processes.

Gas Hydrates- Energy

Natural gas production from methane hydrates may someday prove viable. The USGS Gas Hydrate Project takes part in US and international programs to investigate the potential of deepwater marine and permafrost gas hydrates as an energy resource. Long-term production tests are the next step in this research.

Matrix inhibition PCR and Microtox® 81.9% screening assay analytical results for samples collected for the Sediment-Bound Contaminant Resiliency and Response Strategy pilot study, northeastern United States, 2015

Coastal communities are uniquely vulnerable to sea-level rise (SLR) and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in coming years. The U.S. Geo­logical Survey has developed the Sedime

In situ measurements of compressional wave speed during gravity coring operations in the New England mud patch

This paper presents measurements of sediment sound-speed profiles measured in situ using the acoustic coring system (ACS). The reported measurements were obtained from seven gravity cores collected in the New England Mud Patch. The ACS uses two sets of transducers mounted below the penetrating tip of a sediment corer to make in situ measurements...

Investigating bedload transport under asymmetrical waves using a coupled ocean-wave model

Transport by asymmetrical wave motions plays a key role in cross-shore movement of sand, which is important for bar migration, exchange through tidal inlets, and beach recovery after storms. We have implemented a modified version of the SANTOSS formulation in the three-dimensional open-source Coupled-Ocean-Atmosphere-Wave-Sediment Transport (...

How lipid content and temperature affect American shad (Alosa sapidissima) attempt rate and sprint swimming: Implications for overcoming migration barriers

How seasonal effects such as temperature increases and reduced lipid content affect the ability of anadromous fishes to traverse high-velocity barriers and sprint swimming is poorly understood. We evaluated American shad (Alosa sapidissima) swimming performance in a flume against high flow velocities (2.5–3.7 m·s−1) during the upstream migration...

Surficial geochemistry and bioaccessibility of tellurium in semi-arid mine tailings

Tellurium (Te) is a critical element due to its use in solar technology. However, some forms are highly toxic. Few studies have examined Te behavior in the surficial environment, thus little is known about its potential human and environmental health impacts. This study characterizes two physicochemically distinct Te-enriched mine tailings piles...
