We compared pollinator diversity derived from environmental DNA (eDNA) extracted from flowers and DNA extracted from pulverized bulk samples of insects collected from vane traps deployed at the same sites. We used three metabarcoding primers, two of which target arthropods generally (COI-Jusino and 16S-Marquina) and one that targets bumblebees (Bombus spp., COI-Milam). Across methods, we...

Broad-area, high-resolution, boat-based water quality mapping surveys of the Sacramento-San Joaquin Delta and Suisun Bay (Delta) of California, USA were conducted under different environmental/flow conditions in May, July, and October of 2023. The spatial and temporal variability of nutrients, phytoplankton, and related water quality parameters were assessed. This dataset includes...

In 2003, a lake sturgeon reintroduction experiment was initiated in the Genesee River, NY. Young-of-year hatchery-reared lake sturgeon were released over multiple years. An assessment of the presence of lake sturgeon was done by systematic gill netting using monofilament nets. This data release is the lake sturgeon catch information collected during the systematic gill netting from 2003...

This dataset comprises in situ images of benthic algae collected by an autonomous underwater vehicle (AUV) in Lake Michigan during August and September 2020. The images were annotated, or labeled, to identify specific features for use in machine learning and algorithm development, specifically to train and validate an algorithm for the automated identification and assessment of submerged...

This dataset contains site information and results of flood frequency analysis for 154 urban streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in Washington D.C. and parts of Delaware, Maryland, New Jersey, Pennsylvania, and Virginia. Site information and annual peak-flow data from the 1924 - 2022 water years were obtained from the USGS National Water

This dataset contains site information and results of flood frequency analysis for 64 urban streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in Alabama and Mississippi. Site information and annual peak-flow data from the 1885 - 2024 water years were obtained from the USGS National Water Information System (NWIS) database (U.S. Geological Survey, 2025...

This dataset contains site information and results of flood-frequency analysis for 422 streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in parts of the Upper Mississippi and Souris-Red-Rainy basins and surrounding areas in the United States. Annual peak-flow data from the 1844 - 2013 water years were used in the study (U.S. Geological Survey, 2024)...

Seamless topographic-bathymetric (topo-bathy) profiles and their derived morphologic characteristics were developed for sandy coastlines along the Atlantic and Gulf coasts of the United States. The topo-bathy profiles are published as a database in the Hierarchical Data Format version 5 (HDF5) which contain cross-shore distance coordinates, Universal Transverse Mercator (UTM) coordinate...

The data represent sediment depth profiles of gamma-emitting radionuclides and major, minor, and trace elements in native soil locations around four mineralized sites in Mohave County, Arizona. The four sites represent breccia pipe uranium deposits in the Grand Canyon Region in various lifecycle stages of mining: EZ2 complex (exploration), Arizona 1 mine (standby), Pinenut mine (closed...

The data represent sediment depth profiles of gamma-emitting radionuclides cesium-137 (Cs-137), lead-210 (Pb-210), lead-214 (Pb-214), and bismuth-214 (Bi-214) in native soil locations around four mineralized sites in Mohave County, Arizona. The four sites represent breccia pipe uranium deposits in the Grand Canyon Region in various lifecycle stages of mining: EZ2 complex (exploration)...

This data set includes the audio-magnetotelluric (AMT) sounding data collected from 1997 to 2004 in and near the Rio Grande rift, New Mexico. The U.S. Geological Survey conducted a series of multidisciplinary studies, including magnetotelluric surveys, in the Rio Grande rift to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits...

Quantitative PCR results for samples collected from the Hudson River near Troy, New York by autonomous and manual (backpack) samplers
