Sea Level and Storm Hazards: Past and Present

Sea level and Storm Hazards: Past and Present is a multidisciplinary study of past changes in sea level. Prehistoric shorelines can be used as a baseline for current and future sea level changes under warmer-than-present climate. Emphasis is placed on looking at sea levels during warm periods of the last 500,000 years as well as how base level changes increase the risk of coastal inundation...

Macrofossil and Sediment Processing Laboratory

In the Macrofossil and sediment processing lab we analyze the physical, biological, and geochemical characteristics of peat and sediment samples collected from lake, wetland, and peat cores as proxies for past changes to these depositional environments on timescales of decades to millennia. We primarily study terrestrial wetland ecosystems from subtropical to arctic regions in order to...

2015 Appalachian Floods and Hurricane Joaquin

Learn more about USGS flood activities related to the 2015 Appalachian Floods and Hurrican Joaquin. An upper atmospheric low-pressure system over the Southeast combined with moisture from Hurricane Joaquin off the Atlantic coast to create historic rainfall in early October, 2015, across South Carolina.

Economics, Energy Resources, and Future Energy Supply

The members of this project have prepared a number of analyses that constitute the economic components of energy resource assessments. They have also proposed enhancements to geologic assessment data and methods that make results of assessments immediately amenable to economic analysis. In addition, they apply theoretically sound valuation methodologies to assess the commercial value of...

Geochemistry of Energy Fuels Task

Geologic and geochemical processes that impact fuel quality, quantity, and availability can be best understood by utilizing a range of approaches, including, but not limited to isotopic signatures, inorganic and organic analyses, and neutron scattering techniques. Current work focuses on using neutron scattering to understand how fluids are stored and flow through tight continuous reservoirs...

Recreational Fishing as driver of overexploitation in inland waters- Doug Beard

Do fisheries managers know the impacts of improving recreational fishing technology on the populations of fish they manage? The role of gear innovations in recreational fisheries is understudied as a driver of overexploitation in inland waters. Examining technology advances will inform recreational managment.

Peatland responses to centennial and millennial-scale changes in North Pacific hydroclimate- Miriam Jones

This study will examine centennial- to millennial-scale North Pacific hydroclimate variability over the late-glacial and Holocene from Alaskan peatlands using cellulose extraction from peatland plants. Hydroclimate analysis will be coupled with vegetation and carbon dynamics to better understand how peatlands respond to long-term climate variability.

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...
