Data

This data release contains data collected using a thermogravimetric analyzer (TGA) of rock samples collected from the Escanaba Trough hydrothermal vent field, Gorda Ridge, in the northeast Pacific Ocean. These data were collected in 2022 on expedition TN403 (USGS Field Activity 2022-621-FA). Samples were taken to the USGS Pacific Coastal Marine Science Center for subsampling before being...

We measured juveniles from four species, black carp (Mylopharyngodon piceus), bighead carp (Hypophthalmichthys nobilis), silver carp (H. molitrix), and grass carp (Ctenopharyngodon idella), for thiaminase activity. These data provide previously unknown information about thiaminase activity of three emerging threats (bighead carp, black carp, and grass carp) to the Great Lakes. We tested...

This data release contains a digital geospatial dataset generated by the U.S. Geological Survey under a cooperative agreement with the Water Replenishment District of Southern California to characterize the three-dimensional hydrogeology of the Los Angeles Coastal Plain. The geospatial dataset covers about 580 square miles of the largest coastal plain of southern California and contains...

This data release contains water level observations from a sensor grid deployed in the tidal marshes of the Charles H. Wheeler Wildlife Management Area in the central Long Island Sound (Connecticut, USA). Water level sensors were deployed between August 2018 and December 2018 to serve as a calibration/validation (cal/val) dataset for the development, refinement, and evaluation of remote...

Tiltmeter data on the Island of Hawaiʻi collected by the Hawaiian Volcano Observatory from July 1, 2025 to present with 60-day latency. These data are collected by the USGS Hawaiian Volcano Observatory. This dataset will be updated as new tiltmeter data are collected and approved with 60-day latency.

The U.S. Geological Survey (USGS) Woods Hole Coastal and Marine Science Center deployed a four-legged bottom landing frame (nanopod) containing oceanographic instruments to collect measurements of winter wave conditions directly offshore of Marconi Beach in Wellfleet, MA. Supplementary sediment samples were collected to characterize grain size. Marconi Beach is the site of ongoing...

In 2023, the USGS 3D Elevation Program (3DEP) funded the collection of topo-bathymetric lidar (sometimes referred to as "green lidar") in the Santiam River Basin, Oregon. As part of this acquisition, lidar data were collected on the North, Middle and South Santiam and Santiam Rivers, encompassing reaches upstream of Detroit, Green Peter and Foster Lakes on each river and extending...

The U.S. Geological Survey deployed small uncrewed aircraft systems (sUAS) to collect aerial remote sensing data across sites within the Lower Darby Creek Superfund Site ~5 miles outside of Philadelphia, PA in March and August of 2025. March datasets include aerial images and lidar. August datasets include aerial images from natural color (RGB) and multispectral sensors, and lidar. These

This U.S. Geological Survey (USGS) data release contains data that allows for calculation of total dissolved-solid loads for high-flow and baseflow conditions in the Upper Colorado River Basin (UCRB) collected between 2021 and 2023. High-flow hydrologic events are critical periods for salinity transport but are often underrepresented in existing datasets due to limited sampling and...

Embryonic zebrafish (Danio rerio) were exposed to 0, 1, 5, 10, or 50 micrograms per liter carbamazepine (CBZ) from 2 hours post fertilization (hpf) through hatching, and then sampled at 48, 72, or 144 hpf. Larvae collected at 48, 72, and 144 hpf were assessed for transcriptomic profiles using RNA sequencing. Larvae collected at 72 and 144 hpf time points were assessed for histological...

Pollutants present in stormwater runoff can severely degrade water quality in aquatic habitats. The tire-derived chemical 6PPD-quinone is one such pollutant present in stormwater that is known to significantly impact the survival of salmonids. 6PPD-quinone is derived from 6PPD, the primary antiozonant used to protect tire rubber from ozone attack and degradation. Alternative antiozonants...
