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.

Soil Properties of Tidal Marshes Across Don Edwards San Francisco Bay National Wildlife Refuge, California Soil Properties of Tidal Marshes Across Don Edwards San Francisco Bay National Wildlife Refuge, California
Soil cores were collected across the marshes of Don Edwards San Francisco Bay National Wildlife Refuge in California to assess belowground properties and for radioisotope dating. Data from the soil cores include dry bulk density, organic matter proportion, carbon, and accretion rates. These data were then used to calibrate a wetland model (WARMER3) to assess future elevation and...
Data for the Revised Marine Bird Collision and Displacement Vulnerability Index for Pacific Outer Continental Shelf Offshore Wind Energy Development Data for the Revised Marine Bird Collision and Displacement Vulnerability Index for Pacific Outer Continental Shelf Offshore Wind Energy Development
To better inform continued offshore wind energy development in the region, U.S. Geological Survey, Western Ecological Research Center (USGS-WERC) has updated the database of marine bird vulnerabilities to offshore wind energy infrastructure (OWEI) in the Pacific Outer Continental Shelf Region (POCS; waters within the Exclusive Economic Zone off California, Oregon, and Washington). The...
Data Describing Changes in Aboveground Live Tree Carbon With and Without Restoration Treatments in Second-growth Coastal Redwood Forests Data Describing Changes in Aboveground Live Tree Carbon With and Without Restoration Treatments in Second-growth Coastal Redwood Forests
This dataset provides estimates of aboveground forest carbon for all live trees with diameter at breast height at or above 20 centimeters in 151 second-growth forest plots in Redwood National and State Parks. The dataset contains all existing field observations along with projections from the Forest Vegetation Simulator in five year increments from 2024 to 2064.
Expert suggestions for fostering greater habitat model use in public lands management, elicited through surveys and workshops in 2024 Expert suggestions for fostering greater habitat model use in public lands management, elicited through surveys and workshops in 2024
Habitat models can help inform land management, but are not always used where they could be most helpful. In this study, researchers aimed to identify specific actions that could foster greater use of habitat models for managing rare and invasive plants on public lands. The researchers gathered data through surveys and expert elicitation workshops with modelers and model users. One...
Luminescence Data For: Vibracores Collected in 2021 from the Central Florida Gulf Coast Barrier Islands Luminescence Data For: Vibracores Collected in 2021 from the Central Florida Gulf Coast Barrier Islands
This report summarizes the dating results from sedimentary deposits sampled by the St. Petersburg Coastal and Marine Science Center and analyzed at the USGS Luminescence Geochronology Laboratory. Within this report, we detail the luminescence measurement, equivalent dose determination, and dating-related calculations. We recommend that this report be included as the supplementary...
Watershed Attributes for Chesapeake Stream Team Field Sites Watershed Attributes for Chesapeake Stream Team Field Sites
The Chesapeake Stream Team studied 123 streams from 2021 to 2024 to determine whether conservation practices in agricultural and urban settings have improved downstream nontidal stream health. To isolate effects of conservation practices, scientists must account for other attributes in the greater watershed that may affect measured metrics of stream health. This release includes over 450
Soil-water content and soil temperature data near Sugarloaf Mountain, Colorado, USA Soil-water content and soil temperature data near Sugarloaf Mountain, Colorado, USA
This product is a dataset of volumetric soil-water content and soil temperature in an area affected by wildfire in the Boulder Creek watershed, in the Colorado Front Range, USA. The data contained in this archive continue through 7 years of recovery following a wildfire in 2010. Automated sensors (Decagon Devices, 5TE and 5TM) were used to collect the data at 1-minute and 5-minute...
Streamflow recession indices computed by automation within and proximal to the Mobile Bay and Perdido Bay watersheds, south-central United States Streamflow recession indices computed by automation within and proximal to the Mobile Bay and Perdido Bay watersheds, south-central United States
This data release presents streamflow recession analyses and supporting statistics for 164 U.S. Geological Survey (USGS) streamgages located in or near the watersheds of Mobile and Perdido Bays in the south-central United States (see Tatum and others, 2024). Streamgages were selected based on a minimum of two complete decades of daily streamflow data since January 1, 1950, with the...
Geophysical and video logs of eight wells in the Camas prairie, Idaho Geophysical and video logs of eight wells in the Camas prairie, Idaho
In cooperation with the Idaho Department of Water Resources (IDWR), the U.S. Geological Survey (USGS) collected groundwater levels, geophysical logs, and video logs at eight monitoring wells from the Camas prairie, Idaho, between November 5 and November 8, 2024. The Camas Prairie (study area) is an intermountain basin of southern Idaho, located 75 miles east-southeast from the state’s...
Headwater and downstream attributes for select HUC12 units across the Conterminous United States (CONUS) Headwater and downstream attributes for select HUC12 units across the Conterminous United States (CONUS)
This dataset contains topographic, climatic and land cover attributes for headwaters (stream orders 1 and 2 ) as defined by the National Hydrography Dataset High Resolution (NHDHR) and downstream areas (stream orders 3 and up) for a subset of Conterminous United States (CONUS) HUC12s. Specifically, this dataset contains 2021 National Land Cover Database (NLCD) land cover for the...
Survival, neonate counts, and water quality measurements in controlled exposures to long-term wildland fire retardants to Ceriodaphnia dubia Survival, neonate counts, and water quality measurements in controlled exposures to long-term wildland fire retardants to Ceriodaphnia dubia
We investigated the survival and reproductive success of Ceriodaphnia dubia that were exposed to a concentration series of four current-use fire retardants (Phos-Chek 259-Fx Phos-Chek MVP-Fx, Phos-Chek LC95A-Fx, and Phos-Chek LC95A-R) to determine if exposure duration and concentration of the product altered the survival of C. dubia and the number of neonates produced by C. dubia. We...
Longer exposure to warm water increases subsequent thermal tolerance of brook trout in cold water: acclimation timing and physiology Longer exposure to warm water increases subsequent thermal tolerance of brook trout in cold water: acclimation timing and physiology
This record contains data generated from a laboratory-based study examining the persistence of warm water acclimation following cold water recovery in an iconic cold-water species, the Eastern brook trout. The data set includes Critical Thermal Tolerance (CTmax) measures of fish in treatment groups: control (15 degrees C throughout), 1, 3, 7, and 14 days in warm water exposure (22...
