Causality-informed Bayesian inference for rapid seismic ground failure and building damage estimation

Rapid and accurate estimates of seismic ground failure and building damage are beneficial to efficient emergency response and post-earthquake recovery. Traditional approaches, such as physical and geospatial models, have poor accuracy and resolution due to large uncertainties and the limited availability of informing geospatial layers. The introduction of remote sensing techniques has shown potent

Utilization of genetic data to inform native Brook Trout conservation in North Carolina

As North Carolina’s only native salmonid, Brook Trout Salvelinus fontinalis is a fish of considerable ecological and cultural significance in the state, but anthropogenic alterations to the landscape and introductions of nonnative salmonids have fragmented and reduced its native range. As a result, the North Carolina Wildlife Resources Commission (NCWRC) has enacted numerous efforts to help conser

Opportunities to improve water quality during abandoned mine-tunnel reclamation

In the western United States, bulkheads are constructed to limit drainage from abandoned, draining mine adits and to protect downstream resources from uncontrolled releases of degraded adit water. Although bulkheads improve safety and water-quality conditions at the mouth of the adit, elevated hydraulic pressure behind the bulkhead often causes continuing water-quality problems in new locations. S

Critical ShakeCast lifeline users and their response protocols

ShakeCast is a US Geological Survey (USGS) software application that automatically retrieves ShakeMap shaking estimates and performs analyses using fragility functions for buildings and lifelines. The ShakeCast system aims to identify which facilities or lifeline segments are most likely impacted by an earthquake—and thus which ones should be prioritized for inspection and response—and sends notif

Inclusive lunar exploration: Lunar Surface Science Workshop virtual session 13

This report reviews and presents findings from the Lunar Surface Science Workshop Virtual Session 13: Inclusive Lunar Exploration. The report consists of a brief introduction to the workshop, followed by summaries of the six workshop sessions, and a synthesis section discussing seven key findings.

Ecological Coastal Units – Standardized global shoreline characteristics

A new set of resources is now available that describe global shoreline characteristics. High resolution (30 m), globally comprehensive Coastal Segment Units (CSUs) and Ecological Coastal Units (ECUs) were developed in a collaboration between the U.S. Geological Survey (USGS), Esri, and the Marine Biodiversity Observation Network (MBON). The data were produced from a segmentation and characterizati

Defining the Hoek-Brown constant mi for volcanic lithologies

The empirical Hoek-Brown failure criterion is a well-known and commonly used failure criterion for both intact rocks and rock masses, especially in geological engineering. The intact criterion is calculated using experimental triaxial compression test results on intact samples while the rock mass criterion modifies the intact strength using quantified measures of the rock mass quality. The Hoek-Br

PHREEQ-N-AMDTreat+REYs water-quality modeling tools to evaluate acid mine drainage treatment strategies for recovery of rare-earth elements

The PHREEQ-N-AMDTreat+REYs water-quality modeling tools have the fundamental capability to simulate aqueous chemical reactions and predict the formation of metal-rich solids during the treatment of acid mine drainage (AMD). These new user-friendly, publicly available tools were expanded from the PHREEQ-N-AMDTreat tools to include the precipitation of rare-earth elements plus yttrium (REYs) and the

Determination and prediction of rare earth element eeochemical associations in acid mine drainage treatment wastes

Acid mine drainage (AMD) has been proposed by various researchers as a novel source of rare earth elements (REE), a group of elements that include critical metals for clean energy and modern technologies. REE tend to be sequestered in the Fe-Al-Mn-rich solids produced during the treatment of AMD. These solids are typically managed as waste, but could be a low-cost, readily available REE source. He

Gene flow and spatial population structure of Brook Trout in a large headwater stream network in Colorado

We studied gene flow of non-native Brook Trout Salvelinus fontinalis in a 60-km section of continuous stream network in the upper Cache la Poudre River basin, where a large-scale reclamation effort to restore federally threatened Greenback Cutthroat Trout Oncorhynchus clarkii stomias (GBCT) is taking place. This effort—the Poudre Headwaters Project—represents the most important recovery effort of

Conservation genetics and wild trout: Evolving opportunities to support management

It is increasingly apparent that our planet is undergoing rapid, unprecedented environmental change. These changes are already impacting wild trout populations, leading to declines in occupancy and abundance across increasingly fragmented landscapes. Many changes are projected to intensify in the coming decades, which are likely to be crucial to the future of many wild populations. While there is

Benefits of genetic data for the design of Brook Trout translocation efforts

With wild trout populations in decline, many conservation practitioners are evaluating the feasibility of incorporating reintroduction and genetic rescue into management frameworks. As interest in these conservation tools continues to grow, so too has the need for rigorous science to evaluate translocation success and improve the efficacy of future efforts. From this, it has become increasingly ap
