Burke Minsley is a Research Geophysicist with the Geology, Geophysics, and Geochemistry Science Center.
Burke Minsley joined the USGS in 2008 as a Research Geophysicist with the Geology, Geophysics, and Geochemistry Science Center in Denver, Colorado. After receiving a B.S. in Applied Physics from Purdue University in 1997, Burke began his career as a field geophysicist working on offshore seismic vessels before receiving a Ph.D. in Geophysics from MIT in 2007. His work involves the development and implementation of innovative ground-based and airborne geophysical methods used in interdisciplinary studies to improve our understanding of Earth's geosphere, hydrosphere, and cryosphere. Burke's projects are interdisciplinary and geographically diverse, including permafrost mapping in Alaska, critical zone studies in a mountain headwater system in Colorado, and a large regional water availability study in the lower Mississippi River valley. He also works on development of computational methods for uncertainty quantification in geophysical datasets and associated geologic or hydrologic interpretations. In 2012, Burke received the PECASE award for his fundamental research on advancing airborne electromagnetic survey methodology and its use in studying permafrost. He is currently serving as President of the Near-Surface Geophysics Section of AGU from 2021-2022.

Quantifying model structural uncertainty using airborne electromagnetic data
The ability to quantify structural uncertainty in geological models that incorporate geophysical data is affected by two primary sources of uncertainty: geophysical parameter uncertainty and uncertainty in the relationship between geophysical parameters and geological properties of interest. Here, we introduce an open-source, trans-dimensional Bayesian Markov chain Monte Carlo (McMC) algorithm GeoAuthorsBurke J. Minsley, N. Leon Foks, Paul A. BedrosianWildfire-initiated talik development exceeds current thaw projections: Observations and models from Alaska's continuous permafrost zone
As the Arctic warms and wildfire occurrence increases, talik formation in permafrost regions is projected to expand and affect the cycling of water and carbon. Yet, few unified field and modeling studies have examined this process in detail, particularly in areas of continuous permafrost. We address this gap by presenting multimethod, multiseasonal geophysical measurements of permafrost and liquidAuthorsDavid Rey, Michelle A. Walvoord, Burke J. Minsley, Brian A. Ebel, Clifford I. Voss, Kamini SinghaCharacterizing the diverse hydrogeology underlying rivers and estuaries using new floating transient electromagnetic methodology
The hydrogeology below large surface water features such as rivers and estuaries is universally under-informed at the long reach to basin scales (tens of km+). This challenge inhibits the accurate modeling of fresh/saline groundwater interfaces and groundwater/surface water exchange patterns at management-relevant spatial extents.

Growing water stress has led to emerging interest in protecting fresh and brackish groundwater as a potential supplement to water supplies and raised questions about factors that could affect the future quality of fresh and brackish aquifers. Limited well infrastructure, particularly in regions where elevated salinity has led to limited historical groundwater development, hinders traditional mappiAuthorsLyndsay B.

The New Madrid seismic zone has been the source of multiple major (M ~7.0–7.5) earthquakes in the past 2 ka, yet the surface expression of recent deformation remains ambiguous. Crowleys Ridge, a linear ridge trending north‐south for 300+ km through the Mississippi Embayment, has been interpreted as either a fault‐bounded uplift or a nontectonic erosional remnant.

MinsleyHigh-resolution mapping of the freshwater-brine interface using deterministic and Bayesian inversion of airborne electromagnetic data at Paradox Valley, USA
Salt loads in the Colorado River Basin are a primary water quality concern. Natural groundwater brine discharge to the Dolores River where it passes through the collapsed salt anticline of the Paradox Valley in western Colorado is a significant source of salt to the Colorado River. An airborne electromagnetic survey of Paradox Valley has provided insights into the 3D distribution of brine in theAuthorsLyndsay B. Ball, Paul A. Bedrosian, Burke J. MinsleyInversion of airborne EM data with an explicit choice of prior model
Inversion of airborne electromagnetic (AEM) data is an under-determined inverse problem, in that infinitely many resistivity models exist that will be able to explain the observed data, within measurement errors. Therefore, additional information or constraints must be taken into account to solve the inverse problem. In deterministic approaches, the goal is to locate one optimal model that can beAuthorsThomas Mejer Hansen, Burke J. MinsleyInvestigating lake-area dynamics across a permafrost-thaw spectrum using airborne electromagnetic surveys and remote sensing time-series data in Yukon Flats, Alaska
Lakes in boreal lowlands cycle carbon and supply an important source of freshwater for wildlife and migratory waterfowl. The abundance and distribution of these lakes are supported, in part, by permafrost distribution, which is subject to change. Relationships between permafrost thaw and lake dynamics remain poorly known in most boreal regions. Here, new airborne electromagnetic (AEM) data collectAuthorsDavid Rey, Michelle Ann Walvoord, Burke Minsley, Jennifer Rover, Kamini SinghaDevelopment of perennial thaw zones in boreal hillslopes enhances potential mobilization of permafrost carbon
Permafrost thaw alters subsurface flow in boreal regions that in turn influences the magnitude, seasonality, and chemical composition of streamflow. Prediction of these changes is challenged by incomplete knowledge of timing, flowpath depth, and amount of groundwater discharge to streams in response to thaw. One important phenomenon that may affect flow and transport through boreal hillslopes is dAuthorsMichelle A. Walvoord, Clifford I. Voss, Brian A. Ebel, Burke J.

Disturbance related to fire or hydrologic processes can cause degradation of deep (greater than 1 m) permafrost. These changes in deep permafrost have the potential to impact landscapes and infrastructure, alter the routing and distribution of surface water or groundwater, and may contribute to the flux of carbon to terrestrial and aquatic ecosystems.

Permafrost is found throughout northern latitudes, and hasfar reaching implications for natural and man-made environments including hydrologic processes, landscape dynamics, ecosystems, and infrastructure. While maps of near-surface permafrost characteristics are available, relatively little is known about permafrost distributions at depth over large areas.

Geologic controls on groundwater flow, particularly in tectonically and topographically complex mountainous terrain, can be difficult to quantify without a detailed understanding of the regional subsurface geologic structure. This structure can influence the magnitude of groundwater flow through the mountain block, which in turn impacts groundwater composition and the flux of metals and nutrientsAuthorsBurke J.
