Stormwater concentrations of tire wear particle leachate compounds and survival of early instar mayflies (Neocloeon triangulifer) exposed to 6PPD and transformation products Stormwater concentrations of tire wear particle leachate compounds and survival of early instar mayflies (Neocloeon triangulifer) exposed to 6PPD and transformation products
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...
Buffalo and Silver Carp individual and survival data following surgery using the sedation methods at Columbia Environmental Research Center, Columbia, Missouri, USA from 2022 to 2023 Buffalo and Silver Carp individual and survival data following surgery using the sedation methods at Columbia Environmental Research Center, Columbia, Missouri, USA from 2022 to 2023
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
Vegetation and soil data from reclaimed oil and gas well pads managed by the Bureau of Land Management, Carlsbad Field Office, New Mexico Vegetation and soil data from reclaimed oil and gas well pads managed by the Bureau of Land Management, Carlsbad Field Office, New Mexico
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...
Gila spp. (bonytail chub, humpback chub, and roundtail chub) genomic data from various locations including the Colorado River in the Grand Canyon (2020-2024) Gila spp. (bonytail chub, humpback chub, and roundtail chub) genomic data from various locations including the Colorado River in the Grand Canyon (2020-2024)
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...
Nodal Seismometer Recordings of Aftershocks of the 5 December 2024 M 7.0 Offshore Cape Mendocino, California Earthquake Nodal Seismometer Recordings of Aftershocks of the 5 December 2024 M 7.0 Offshore Cape Mendocino, California Earthquake
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...
Properties of sediment collected from channels in northern San Francisco Bay, California, 2024 Properties of sediment collected from channels in northern San Francisco Bay, California, 2024
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...
