Sublacustrine landslide and tsunami models from Lake Quinault, Washington Sublacustrine landslide and tsunami models from Lake Quinault, Washington
This USGS data release provides model setup files to simulate a hypothetical sublacustrine landslide in Lake Quinault and resulting tsunami waves.
Seismic reflection data imaging the Meadow Bank scarp in the Wabash Valley Seismic Zone, southeastern Illinois, U.S. Geological Survey data release Seismic reflection data imaging the Meadow Bank scarp in the Wabash Valley Seismic Zone, southeastern Illinois, U.S. Geological Survey data release
The U.S. Geological Survey, in collaboration with seismologists from University of Kentucky, performed a 917-meter east-west oriented shear horizontal (SH)-wave seismic-reflection survey in the Wabash Valley Seismic Zone in southeastern Illinois. The resulting profile, named ML-2, images the near-surface geology underlying the Meadow Bank scarp, a roughly 10-km long northeast-oriented...
Stakeholder Engagement for Water-Hazard Science and Response in the USGS Rocky Mountain Region Stakeholder Engagement for Water-Hazard Science and Response in the USGS Rocky Mountain Region
Stakeholder engagement is essential to successful development and implementation of products and services supporting emergency management. Governmental agencies often have a unique challenge of ensuring equitable stakeholder representation across large geographic, administrative, and topical areas. This project used stakeholder engagement to understand end-users needs concerning water...
Phytoplankton Species Composition and Abundance in the Sacramento-San Joaquin River Delta: Microscopic Enumeration of USGS Samples, beginning in 2016 (ver. 2.0, December 2025) Phytoplankton Species Composition and Abundance in the Sacramento-San Joaquin River Delta: Microscopic Enumeration of USGS Samples, beginning in 2016 (ver. 2.0, December 2025)
This dataset contains multiple types of data characterizing phytoplankton in the Sacramento-San Joaquin Delta (California, USA). 1) Bright field microscopy was used to identify and enumerate phytoplankton community composition; 2) Epifluorescent microscopy was used to enumerate picophytoplankton (phytoplankton cells less than 2 microns in diameter) and, 3) a categorical visual index...
Phytoplankton, algal toxin, and water-quality data for Blue Mesa Reservoir, Colorado, 1970–2023 Phytoplankton, algal toxin, and water-quality data for Blue Mesa Reservoir, Colorado, 1970–2023
Blue Mesa Reservoir (Blue Mesa) is the largest storage reservoir in Colorado and is used for water supply and recreation. The reservoir consists of three distinct basins which are, moving from east to west, Iola, Cebolla, and Sapinero. This data release includes a wide variety of data collected to understand conditions that contribute to algal blooms in Blue Mesa. Data include...
Predictive layers of trace elements in soil in the conterminous United States Predictive layers of trace elements in soil in the conterminous United States
This dataset provides posterior mean predicted rasters of the distribution of trace elements important to vertebrate health (cobalt, copper, iron, manganese, selenium, and zinc) in the soil across the conterminous United States. Rasters were generated using a Bayesian modeling framework implemented in R with the R-INLA framework (Integrated Nested Laplace Approximation) and the...
