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.

Capture-Mark-Recapture Science

Capture-Mark-Recapture (CMR) can be viewed as an animal survey method in which the count statistic is the total number of animals caught, and the associated detection probability is the probability of capture.  The method involves capturing a number of animals, marking them, releasing them back into the population, and then determining the ratio of marked to unmarked animals in the population...

Regression models for estimating sediment and nutrient concentrations and loads at the Iroquois River near Foresman, Indiana, March 2015 through July 2018

In 2015, the U.S. Geological Survey, in cooperation with the Iroquois River Conservancy District, deployed continuous water-quality monitors and began collecting representative discrete water-quality samples at the Iroquois River near Foresman, Indiana, streamflow-gaging station (U.S. Geological Survey station 05524500). By relating continuously...

Deer do not affect short-term rates of vegetation recovery in overwash fans on Fire Island after Hurricane Sandy

1. Coastal resilience is threatened as storm-induced disturbances become more frequent and intense with anticipated changes in weather patterns. After severe storms, rapid recovery of vegetation, especially that of dune-stabilizing plants, is a fundamental property of coastal resilience. Herbivores may affect resilience by selectively foraging...

Decline of the North American avifauna

Species extinctions have defined the global biodiversity crisis, but extinction begins with loss in abundance of organisms that can result in extreme compositional and functional changes of ecosystems. Using multiple and independent monitoring networks, we report major population losses across much of the North American avifauna, including in once...

Permeability anisotropy and relative permeability in sediments from the National Gas Hydrate Program Expedition 02, offshore India

Gas and water permeability through hydrate-bearing sediments essentially governs the economic feasibility of gas production from gas hydrate deposits. Characterizing a reservoir’s permeability can be difficult because even collocated permeability measurements can vary by 4-5 orders of magnitude, due partly to differences between how various...

Pressure core based onshore laboratory analysis on mechanical properties of hydrate-bearing sediments recovered during India's National Gas Hydrate Program Expedition (NGHP) 02

A solid understanding of the mechanical properties of hydrate-bearing sediments is essential for the safe and economic development of methane hydrate as an energy resource. In 2015, 104 pressure cores were collected, recovering sediments from above and within concentrated hydrate reservoirs in the Krishna-Godavari Basin, as part of India’s...

Compressibility and particle crushing of Krishna-Godavari Basin sediments from offshore India: Implications for gas production from deep-water gas hydrate deposits

Depressurizing a gas hydrate reservoir to extract methane induces high effective stresses that act to compress the reservoir. Predicting whether a gas hydrate reservoir is viable as an energy resource requires enhanced understanding of the reservoir’s compressibility and susceptibility to particle crushing in response to elevated effective stress...
