U.S. Coal Resources and Reserves Assessment

The U.S. Coal Resources and Reserves Assessment Project, as part of the U.S. Geological Survey (USGS) Energy Resources Program, conducts systematic, geology-based, regional assessments of significant coal beds in major coal basins in the United States. These assessments detail the quantity, quality, location, and economic potential of the Nation’s remaining coal resources and reserves and...

Remote Sensing Techniques for Characterizing Energy Resources in Waste

Funded by the USGS Energy Resource Program “Shark Tank” grant. The goal of this project is to develop a method to use remotely collected satellite and airborne data to ascertain the quantity and quality of waste at abandoned uranium mines to better estimate the resource potential, identify abandoned mines and explore potential applications to other energy resources.  This is a collaborative...

Assessing Emissions from Active and Abandoned Coal Mines

The gas emission zone liberates and accumulates significant amounts of coal mine methane as a by-product of active mining. In most active mines, coal mine methane is controlled by wellbores, called gob gas ventholes. Despite the presence of these wellbores, it is not possible to capture all of the methane generated within the gas emission zone. As a consequence, a large amount of gas migrates...

Introduction to linked and dynamic decisions

Often, a decision maker is faced with a series of linked decisions, rather than an isolated one-off decision. In natural resource management, it is common to make a similar type of decision on a regular basis (e.g., annually). Such linked decisions have two important properties: they are dynamic, that is, the actions taken early on affect...

As Earth’s climate rapidly changes, species range shifts are considered key to species persistence. However, some range-shifting species will alter community structure and ecosystem processes. By adapting existing invasion risk assessment frameworks, we can identify characteristics shared with high-impact introductions and thus predict potential...
