Hidden system identification: Basin modeling as a tool for examining sedimentary geothermal resource potential
Rand Gardner, Justin E. Birdwell
2023, Conference Paper, Using the Earth to save the Earth
Three-dimensional (3D) geologic and temperature models have been developed for the onshore U.S. Gulf Coast. The results from these models identify areas of moderate- to high-temperature (90°-150°C and >150°C; respectively) geothermal resources at depths <6 km. This modeling study addresses the fundamental challenge of predicting where opportune temperature and lithology...

2023, Conference Paper, Proceedings of the 17th multidisciplinary conference on sinkholes and the engineering and environmental impacts of karst
Identifying and analyzing closed depressions in karst areas is important for sinkhole hazard evaluation and land management. We created a sinkhole inventory in the karst region of northwest Puerto Rico using a lidar-derived elevation model acquired in 2018 approximately eleven months after Hurricane Maria. The goal of this project is...
Red Knot stopover population size and migration ecology at Delaware Bay, USA, 2023
James E. Lyons
2023, Report
Red Knots (Calidris canutus rufa) stop at Delaware Bay on the mid-Atlantic coast of North America during northward migration to feed on eggs of horseshoe crabs (Limulus polyphemus).

2023, Journal of Fish and Wildlife Management (14) 385-399
The accuracy of posttranslocation population monitoring methods is critical to assessing long-term success in translocation programs. Translocation can produce unique challenges to monitoring efforts; therefore, it is important to understand the flexibility and robustness of commonly used monitoring methods. In Florida, USA, thousands of gopher tortoises Gopherus polyphemus have been, and continue...
