Data Releases

This dataset contains an input of calculated average monthly rainfall values for Guam and drought time series data that covers two islands. The Guam drought time series is based on the standardized precipitation index (SPI) three-month intervals (SPI-3) and twelve-month intervals (SPI-12). Calculated from monthly rainfall values from 1954 through 2020 were produced for the whole land...

This data release includes nest box field observations (N = 98 nest boxes) and avian egg tissue laboratory analyses (N = 60 eggs) collected from Lake Koocanusa (also known as Koocanusa Reservoir) and the Kootenai River Basin, Montana, 2022-2023. Nest box field observation data (occupancy rate, clutch size, and hatching success) and avian eggs were collected by the U.S. Fish and Wildlife...

This data release includes electron microprobe and 40Ar/39Ar data collected at the U.S. Geological Survey for samples from the Raft River metamorphic core complex in Utah, USA. Rock samples were collected by Raphael Gottardi, currently at Auburn University. Muscovite in thin sections from quartzites, micaceous quartzites, and quartz-kyanite rocks were analyzed by electron probe...

Coastal communities are uniquely vulnerable to sea-level rise and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in subsequent years. The U.S. Geological Survey has developed the Sediment...

To explore the capacity of microbiota to reflect water quality, we advanced methods using flow cytometry for measuring bacterial metabolic activity. After exposure of three bacterial species to five compounds that can be found in watersheds (i.e., an herbicide, a preservative, an antibiotic, and two hormones), flow cytometry methodology was used to measure esterase activity.

USGS’s Southeast Climate Adaptation Science Center and the University of Tennessee, Knoxville are undertaking research to support southeastern states and partners engaged in the process of preparing revisions of State Wildlife Action Plans (SWAPs). This effort focuses specifically on integration of climate change into SWAPs. This data product provides a collation of estimates of species

USGS’s Southeast Climate Adaptation Science Center and the University of Tennessee, Knoxville have launched a research effort to support southeastern states and other partners engaged in the process of preparing revisions of State Wildlife Action Plans for 2025. Specifically, this effort focuses on supporting attempts to integrate climate change considerations into SWAPs. Different...

This data release hosts detrital zircon U-Th-Pb geochronology data that were created to support geologic mapping and research in the context of the Geologic Framework of the Intermountain West Project supported by the National Cooperative Geologic Mapping Program. These data characterize the deposition age and provenance of Cretaceous stratigraphic units exposed in the Piceance Creek...

As part of the U.S. Geological Survey's (USGS) Next Generation Water Observing System (NGWOS) efforts in the Delaware River Basin (DRB), a soil moisture sensing testbed was established at USGS Delaware County Observation Well - DE 723 located in a managed meadow setting in Glen Mills, PA. Traditional in situ soil moisture sensors, a remote sensing cosmic ray neutron sensor (CRNS), and...

We used an 18-year dataset (2001 to 2019) incorporating year, sex, hurricane occurrence and sampling effort to estimate survival using Cormack–Jolly–Seber (CJS) models in Program Mark. Annual survivorship estimates were high from 2001-2003 for both sexes (91-96%) and variable from 2006-2014 (77-92%). Beginning in 2015 survival estimates exhibited a steeper decline (females: 65%, males 75...

In cooperation with the U.S. Army Corps of Engineers, the U.S. Geological Survey evaluated geomorphic conditions within Fern Ridge Lake near Eugene, Oregon, to inform cultural resources management and other natural resources decisions. Reservoir erosion and deposition during seasonal flood-control operations have formed a diverse array of landforms that can impact water storage, aquatic...

This dataset describes (a) concentrations of nutrients and related constituents, and (b) discharge in the lower Boise River (Idaho) and its primary tributaries for Water Years 1994 through 2023 and 1969 through 2024, respectively. Constituents include water column concentrations of suspended sediment, total phosphorus, dissolved phosphorus, orthophosphate as phosphorus, total nitrogen...
