The influence of drying on the aeolian transport of river-sourced sand

Transgression and regression of water levels (stages) have impacted the evolution of aeolian landforms and sedimentary deposits throughout geologic history. We studied this phenomenon over a five-day period of reduced flow on the Colorado River in Grand Canyon National Park, AZ, USA, in March 2021. These transient low flows exposed river-channel sand deposits to the air, causing progressive desicc

Defining biologically relevant and hierarchically nested population units to inform wildlife management

Wildlife populations are increasingly affected by natural and anthropogenic changes that negatively alter biotic and abiotic processes at multiple spatiotemporal scales and therefore require increased wildlife management and conservation efforts. However, wildlife management boundaries frequently lack biological context and mechanisms to assess demographic data across the multiple spatiotemporal s

U.S. Geological Survey Colorado River Basin Actionable and Strategic Integrated Science and Technology (ASIST)—Information Management Technology Plan

IntroductionMore than 840 publications, 575 data releases, and 330 project web pages from the U.S. Geological Survey (USGS) pertain to the Colorado River Basin. Limited interconnections between Colorado River Basin publications, data, and web pages restrict the ability to synthesize and interpret scientific resources. Currently, these pieces are spread across multiple isolated locations, internal

Hunting and Fishing

This page is a work in progress and showcases hunting and fishing as a way of life. The management of fish and wildlife populations for the benefit of current and future generations of all Americans is the foundation of this Nation’s conservation heritage. We help to inform decisions through a variety of actions, from the development and implementation of basic monitoring protocols to complex...

Coproduced Science Linking Environmental and Public-Health Data to Evaluate Drinking Water Arsenic Exposure on Birth Outcomes

U.S. Geological Survey (USGS) scientists teamed up with public-health epidemiologists to probe for associations between arsenic in drinking water and human-birth outcomes. They reported a modest inverse relation between birth weight and arsenic exposure. Findings indicate that future research efforts using individual-level exposure data such as measured arsenic concentrations in tap water could...
