Data

This data release contains data in support of "Regional Analysis of the Dependence of Peak-Flow Quantiles on Climate with Application to Adjustment to Climate Trends" (Over and others, 2025). It contains input and output data used to analyze the effect of climate changes on trends in floods using three regression approaches. The input consists of two files. The first, "station_list.csv,"...

This dataset represents a validation record for Landsat 8/9 Operational Land Imager (OLI) Aquatic Reflectance (AR) products. The dataset consists of combined AERONET-OC (n=418) and GLORIA (n=1,638) hyperspectral remote sensing reflectance (Rrs) measurements in the visible to near infrared spectral bands coincident with same-day OLI acquisitions. The dataset is intended to evaluate the...

Locations of sites at which U.S. Geological Survey (USGS) biologists surveyed for Temblor legless lizards (Anniella alexanderae) from 2022 to 2025 and the results of those surveys. At the time of the species description, little was known about the distribution of the Temblor legless lizard beyond a few localities. Surveys were designed to gather information on the distribution of Temblor...

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...

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...

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.

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...

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...

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...

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...

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...

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...
