Data

This data set contains information on the occurrence and abundance of intertidal marine invertebrates and macro algae collected across five islands with 10 sites in the Boston Harbor in 2023. This data was collected using an intertidal biodiversity monitoring protocol developed specifically for the mixed coarse substrate habitat found on the inner islands of Boston Harbor, including...

U.S. Geological Survey (USGS) scientists and engineers from the Earth Resources Observation and Science Center (EROS) Calibration/Validation Center of Excellence (ECCOE) and the National Uncrewed Systems Office (NUSO) conducted field data collection efforts July 15 – 18, 2023 at the USGS EROS facility in Minnehaha County, South Dakota. The data collected included multispectral (MS) and

This data set contains environmental DNA (eDNA) data enumerating the presence of intertidal marine vertebrates, invertebrates, and macro algae collected across 5 islands with 10 sites in the Boston Harbor in 2023. This data was collected using water samples collected in association with other intertidal biodiversity monitoring protocols developed specifically for the mixed coarse...

U.S. Geological Survey (USGS) scientists conducted field data collection efforts between April 27 and May 2, 2023, at four sites (Fort Zachary Taylor Historic State Park, Bahia Honda State Park, Curry Hammond State Park, and Long Key State Park), in the Florida Keys using high accuracy surveying technologies. Wadded Global Navigation Satellite System (GNSS) points and single beam sonar...

This TX_LowerRioGrande_D22 project called for the planning, acquisition, processing, and derivative products of lidar data to be collected at an aggregate nominal pulse spacing (ANPS) of 0.18 meters (30 ppsm) and 0.35 meters (8ppsm). Project specifications are based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification 2022 Rev A. The data was developed based...

Wildfire can substantially alter the hydrologic response of watersheds to rainfall, and debris-flow activity is among the most destructive consequences of these events. To assist federal, state, and local agencies in planning for postfire hazards, the U.S. Geological Survey (USGS) conducts debris-flow hazard assessments for recent wildfires. This collection holds all postfire debris-flow...

This is an outdated version of the North American Breeding Bird Survey (BBS) dataset that has been superseded by a more recent release. Unless you have a specific need for these archived data, please return to the main page and download the latest data release, which includes all BBS data available to date. The 1966–2024 BBS dataset contains avian point-count data for more than 700 North

Sediment accretion measurements were made at the SMARTX warming experiment at the Smithsonian Environmental Research Center's Global Change Research Wetland. Feldspar marker horizons were established at the beginning of the experiment in 2016 in the warming plots, and were subsequently buried over time by wetland accretion of both organic and inorganic matter. These data include the...

These data include a collection of 3-dimensional (3D) point clouds from three New Mexico landscapes and associated field-collected validation data accompanying each scan. The data were collected in fall of 2022-2023 across three montane New Mexico landscapes - similar in climate but differing in disturbance histories. Landscapes include a intensely and repeatedly burned shrubfield, a...

While the timing and composition of the Yellowstone Plateau volcanic field’s caldera-forming tuffs and rhyolite flows are well-characterized, the chronology of smaller-volume mafic eruptions is poorly known, thereby limiting our understanding of how mafic magmatism drives rhyolite volcanism, particularly Yellowstone’s large caldera-forming eruptions. To address this gap in knowledge, we...

This data release contains the analytical results of seven contaminant classes and four cyanotoxins in water using three types of passive sampling devices. Samples were collected at eight sites on the lower Columbia River and two sites on the lower Willamette River in Oregon and Washington. A Polar Organic Compound Integrating Sampler (POCIS), a Semipermeable Membrane Device (SPMD), and...

The Sacramento-San Joaquin Delta is a crucial river delta that supplies a significant portion of California's freshwater for agricultural and residential use and serves as critical habitat for numerous state and federally listed species of concern. In several areas, urban stormwater drains discharge directly into the Delta. 6PPD-quinone (6PPD-Q, 2-anilo-5-[(4-methylpentan-2- yl)amino...
