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.

Spatial covariance tracks grassland bird community occupancy in fragmented grasslands Spatial covariance tracks grassland bird community occupancy in fragmented grasslands
Grasslands are an imperiled ecosystem, and grassland bird abundance is declining across North America. One of the strongest drivers for these declines is woody plant encroachment of grasslands. In the Great Plains and Sagebrush biomes of North America, spatial covariance—a remote sensing metric for tracking boundaries between vegetation types—is emerging as a new method to identify and...
Oceanographic Time Series Measurements Collected at Madeira Beach, Florida Oceanographic Time Series Measurements Collected at Madeira Beach, Florida
The U.S. Geological Survey (USGS) deployed a series of oceanographic instruments at Madeira Beach, Florida configured to measure water levels, temperature, waves, and three-dimensional flow velocities throughout the water column. The instruments include (1) Spotter wave buoys with Smart Mooring (2) RBR pressure loggers, and (3) RDI Sentinel-V Acoustic Doppler Current Profilers (ADCP)...
Santa Rosa Plain integrated hydrological model: simulating the hydrological system of the Santa Rosa Plain, California with analysis of future climate scenarios Santa Rosa Plain integrated hydrological model: simulating the hydrological system of the Santa Rosa Plain, California with analysis of future climate scenarios
The U.S. Geological Survey (USGS) conducted a study in cooperation with the Sonoma County Water Agency to assess the water resources of the SRPW and develop tools to better understand the groundwater and surface-water systems in the watershed. The foundation of these tools is the development and application of the Santa Rosa Plain hydrologic model (SRPHM) using GSFLOW to simulate...
Dynamic rating model archive Dynamic rating model archive
Ratings are used for a variety of reasons in water-resources investigations. The simplest rating relates discharge to the stage of the river. From a pure hydrodynamics perspective, all rivers and streams have some form of hysteresis in the relation between stage and discharge because of unsteady flow as a flood wave passes. Simple ratings are unable to represent hysteresis in a stage...
Hawaiʻi verbenone repellents for ambrosia beetles on healthy and diseased ʻōhiʻa 2022-2023 Hawaiʻi verbenone repellents for ambrosia beetles on healthy and diseased ʻōhiʻa 2022-2023
In this experiment at Waiākea Forest Reserve, we tested the efficacy of the semiochemical repellent, verbenone, in commercial SPLAT® Verb formulation, at protecting healthy and rapid ʻōhiʻa death-Ceratocystis infested ʻōhiʻa from ambrosia beetle colonization in the 2022 and 2023 field seasons. Data files include 1) raw beetle counts, 2) individual tree information, and 3) verbenone mean...
Microsatellite Genotype Data and Body Condition Data Used to Evaluate Post-Translocation Impacts on the Mogollon Narrow-headed Gartersnake (Thamnophis rufipunctatus) Microsatellite Genotype Data and Body Condition Data Used to Evaluate Post-Translocation Impacts on the Mogollon Narrow-headed Gartersnake (Thamnophis rufipunctatus)
We compared genetic diversity and body condition indices among two source locations in Catron County, New Mexico (Whitewater Creek and Middle Fork Gila) and the recipient population (Saliz Creek) to evaluate individual- and population-level fitness responses related to the admixture of gene pools following the the translocation of Mogollon Narrow-headed Gartersnakes (Thamnophis...
