Colorado River Basin: Building Advanced, Strategic, Innovative,?Integrated?System?Science
The Colorado River Basin is currently experiencing its worst drought in recorded history. The period from 2000 through 2020 is the driest 21-year period in over 100 years and one of the driest periods in the 1,200-year paleo-record. Drought impacts include worsening conditions in the 9 ecoregions, including habitat for several threatened and endangered species, wildland fire risks, reduced...

Non-Traditional Stable Isotopes
Understanding the genesis of ore deposits and their behavior in the environment is a subject of great importance to the Nation. A relatively new tool to aid in these efforts to investigate the origin and environmental effects of ore deposits is the use of "heavy" metal stable isotopes. Our research objectives are to utilize various isotopic systems to advance our understanding of ore genesis...

We tackle these issues with a combination of simulation and statistical...
Critical Elements in Carbonatites: From Exploration Targets to Element Distribution
Critical elements are essential to the modern economy and have potential supply chain disruptions, but compared to most base and precious metals, little work has been done in understanding ore-grade enrichments. Carbonatites are the primary source of the worlds light rare earth elements and niobium, and a potential source for heavy rare earths, scandium, tantalum, and thorium. Project...
Microbial Source Tracking and Escherichia coli Monitoring in the Rio Grande in the South Valley, Albuquerque, New Mexico
The Rio Grande, in southern Albuquerque, is an impaired reach for bacteria. Escherichia coli (E. coli) bacteria are elevated in this reach of the Rio Grande even without stormwater present, during what is referred to as “dry season”. Samples will be collected over a range of flows including during the dry season (November 1st-June30th). Water samples will be analyzed for E. coli and microbial...

Data release for Accounting for Land in the United States: Integrating Physical Land Cover, Land Use, and Monetary Valuation
Land plays a critical role in both economic and environmental accounting. As an asset, it occupies a unique position at the intersection of the System of National Accounts (SNA), the System of Environmental-Economic Accounting Central Framework (SEEA-CF), and (as a spatial unit) SEEA Experimental Ecosystem Accounting (SEEA-EEA), making land a natural starting point for dev
Data release for tracking rates of post-fire conifer regeneration distinct from deciduous vegetation recovery across the western U.S.
Post-fire shifts in vegetation composition will have broad ecological impacts. However, information characterizing post-fire recovery patterns and their drivers are lacking over large spatial extents. In this analysis we used Landsat imagery collected when snow cover (SCS) was present, in combination with growing season (GS) imagery, to distinguish evergreen vegetation from deciduou
