All Data

Data from environmental DNA (eDNA) samples filtered from seawater collected in the Gulf of America during a research expedition on the R/V Point Sur in September 2022. Samples were collected at depths throughout the water column. Each eDNA sample was amplified using four primer sets: MiFish 12S rRNA marker targeting ray-finned fishes; 28S rRNA marker targeting corals and other cnidarians...

Digital flood-inundation map libraries for two reaches that comprise 14.8 miles of the Little and Big Papillion Creeks in Omaha, Nebraska were created by the U.S. Geological Survey (USGS) in cooperation with the Papio-Missouri River Natural Resource District. The flood-inundation maps, which can be accessed through the USGS Flood Inundation Mapping Program website at https://www.usgs.gov...

The objective of this project was to create a shoreline inventory for Hawai‘i Island, the largest and most diverse island in the Hawaiian archipelago. This was done via the collection and processing of high-resolution (

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...

These data are in four tables relating to complete blood count (CBC), biochemistry, blood gas analysis, corticosterone, serum protein electrophoresis, and sample attribute data of adult Pacific (Gavia pacifica) and Red-throated Loons (G. stellata) breeding in northern Alaska in 2023.

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...
