Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Forest Dynamic Model Predictions of Density and Basal Area of Six Invasive Species Across the Ozark Region of the U.S. Midwest under Current Climate (2050) Forest Dynamic Model Predictions of Density and Basal Area of Six Invasive Species Across the Ozark Region of the U.S. Midwest under Current Climate (2050)
This dataset is a collection of TIFF file outputs from the forest dynamic model LANDIS PRO representing projections of the density and basal area for six invasive tree/shrub species under current climate conditions (avaraged from 1980-2009) in the Ozark region of the U.S. Midwest for the year 2050. The six species included in this study are autumn olive, bush honeysuckles, Callery pear...
Spatial Occurrence and Demographic Points of Six Non-Native Invasive Species across the Eastern US (2000-2020) Spatial Occurrence and Demographic Points of Six Non-Native Invasive Species across the Eastern US (2000-2020)
This dataset compiles spatial occurrence and demographic information for six non-native invasive tree and shrub species—autumn olive, bush honeysuckles, Callery pear, princess tree, privet, and tree-of-heaven—across the eastern United States from 2000 to 2020. Occurrence points were obtained from the Early Detection and Distribution Mapping System (EDDMapS), and plot-level observations...
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...
