Data Releases

Endangered pallid sturgeon (Scaphirhynchus albus) spawning habitats were mapped on the Tongue River near Miles, City Montana June in 2023 and 2024. Data quantify the physical characteristics of the river channel and flow; depth, velocity and habitat assessments using single-beam sonar, acoustic Doppler current profilers (ADCPs) in 2023 and single-beam sonar in 2024. Real-time kinematic...

This data release includes sampling location data, the information about sequenced organisms and the SRA accession number for the 16S whole-organism sequencing data for larval aquatic insects, emergent adult insects, and two riparian spiders from Torch Lake and Gratiot Lake (N=3 sites at each Lake). Torch Lake (Houghton County, Keweenaw Peninsula, Michigan, USA) is a Great Lakes Area of...

Data include position data from a VEMCO Positioning Systems (VPS) array at the mouth of the Lamine River. The array was deployed September 3rd and retrieved October 2nd. Position data was generated for all tagged fish detected in the VPS array using Fathom Position software. The data includes 3946 positions for 26 detected tags. The array was deployed as part of a project to remove...

This dataset includes a collection of files related to a project investigating the ecology of six lakes in the Tokopah Basin. The primary purpose of the research project was to understand the dynamics of periphyton growth and the potential relationships with nitrogen and copper concentrations in high elevation lakes of the Sierra Nevada mountains in Sequoia National Park, California...

Tabular and raster data containing spatial capture recapture, GPS telemetry, ground observations, and genetic records for male and female Rocky Mountain bighorn sheep (Ovis canadensis canadensis) in Dinosaur National Monument from 2006 to 2022. Includes associated tabular data files required for analysis of data with spatial capture models and resource selection models, and the raster...

This data set includes concentrations of selected transformation products (TPs) of the tire antioxidant, 6PPD, including 6PPD-quinone (6PPDQ) and 4-hydroxydiphenylamine (4-HDPA) in water samples collected during a rain event from two urban rivers in the Greater Toronto Area, Ontario, Canada. In addition, mortality data from acute toxicity tests with aquatic larvae of the mayfly...

The dataset includes capture and individual data for silver carp and buffalo from 2022 and 2023. Fish were captured in the Missouri River and tributaries and transported to the Columbia Environmental Research Center, Columbia, MO, USA. Fish were assigned to one of four treatments to examine different sedation techniques for surgical implantation of artificial transmitters: tricaine

These data were compiled to support a study of how environmental setting affects the success of well pad reclamation within the region managed by the Bureau of Land Management, Carlsbad Field Office in southeastern New Mexico, USA. The data were collected in 2022 and 2023 and represent vegetation, soil, and climate conditions at 70 reclaimed well pads from 4 to 24 years after the wells...

These data were compiled to investigate genomic patterns in humpback chub (Gila cypha) sampled from various locations (New Mexico and Utah) including the Colorado River in the Grand Canyon, AZ. Specifically, our objectives were to understand 1) if unique genetic variation persisted in the western Grand Canyon during the period when chub was restricted to warm water refugia and 2) if a...

At 10:44:21 local time on December 5, 2024, a M 7.0 earthquake occurred approximately 70 km southwest of Ferndale, California, just west of the Mendocino Triple Junction. Starting the next day, the U.S. Geological Survey deployed nodal seismometers (nodes) in the Eel River Valley, near Cape Mendocino, and along the California Highway 101 corridor to compliment local permanent stations of...

Bed sediment samples were collected from the channels of 4 sites within northern San Francisco Bay, California, USA. The channels sampled were located in Corte Madera Bay, San Pablo Bay, Grizzly Bay and Suisun Bay. Sediment samples were collected with push cores, by subsampling a Gomex box corer. Cores, which ranged in length from 2 to 6 centimeters (cm), were sectioned by depth. The top...

Data were collected as part of a long-term capture-recapture program to assess the status and dynamics of populations of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon and Clear Lake Reservoir, California. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated...
