Several plumes of dissolved, chlorinated solvents, including trichloroethylene, have been identified in a sole-source aquifer near the former Northrop Grumman Bethpage Facility and Naval Weapons Industrial Reserve Plant sites in southeastern Nassau County, New York. Past investigations have documented that the groundwater contamination originated from this industrial area and now extends...

The purpose of this project was to monitor the cave climate of the Sunset Crater National Monument “Bonito Flow” Ice Cave. The main purpose of the climate monitoring was to determine if “Ice Cave” was still an ice cave, i.e., a cave that contains perennial ice. The data acquired from 2 March 2021 to 13 Dec. 2022 consisted of temperature, humidity, and pressure throughout the cave...

Thirteen years ago, as a senior in college, I barely knew what research was. Although I spent my senior year conducting fieldwork and writing 50 pages about Brown Trout Salmo trutta population dynamics in southeast Minnesota streams, the essence of research eluded me. It was not until graduate school that things clicked. A decade ago, I was several months away from completing my M.S...

On Earth, caves are unique environments at the intersection of geology, climate, and biology. Given that the same terrestrial speleogenetic processes exist throughout the solar system, it would be surprising if caves beyond Earth did not exist. Thousands of potential cave entrances (or subsurface access points) have been identified from Earth’s Moon to Pluto’s moon, Charon. To date, our...

The Upper Colorado River Basin is the principal water supply of the western United States and includes a series of canyons that provide habitat for disproportionate numbers of flora and fauna. Following the closing of Flaming Gorge and Blue Mesa dams in 1963 and 1966, decreases in peak flows and elevated base flows allowed extensive vegetation encroachment, channel narrowing, and channel

Low-lying, tropical, coral-reef-lined coastlines are becoming increasingly vulnerable to wave-driven flooding due to population growth, coral reef degradation, and sea-level rise. Early-warning systems (EWSs) are needed to enable coastal authorities to issue timely alerts and coordinate preparedness and evacuation measures for their coastal communities. At longer timescales, risk...
