Copper concentrations and associated morphometric data from brook trout (Salvelinus fontinalis) and copper results from macroinvertebrates and zooplankton at 6 lakes in Sequoia National Park, CA, 2021-2022 Copper concentrations and associated morphometric data from brook trout (Salvelinus fontinalis) and copper results from macroinvertebrates and zooplankton at 6 lakes in Sequoia National Park, CA, 2021-2022
This dataset encompasses a series of files related to a comprehensive ecotoxicology research project conducted in high elevation lakes of the Tokopah Basin in Sequoia National Park. The dataset includes detailed sampling data that reflects the copper concentrations at multiple levels of the food web. This dataset also includes morphometric data for collected fish, biomarkers of fish...
Passive acoustic telemetry detections of Black Carp Mylopharyngodon piceus in the Mississippi River Basin; 2021-2023 Passive acoustic telemetry detections of Black Carp Mylopharyngodon piceus in the Mississippi River Basin; 2021-2023
This dataset represents passively detected locations of acoustic telemetry tagged Black Carp in the Mississippi and Missouri rivers near their confluence. These river segments consisted of both open river and impounded habitat present during observed hydrologic conditions from 2021-2023. Receiver arrays were set in known use areas (determined by active relocations of tagged fish) and set...
Erodium pollen data from Morro Bay Salt Marsh Erodium pollen data from Morro Bay Salt Marsh
Presence/absence data for Erodium pollen in a sediment core taken from the Morro Bay Salt Marsh.
Stream stage, stream temperature, and climate metrics for 30 streams spanning land use and management gradients in a mixed agricultural region in Pennsylvania and Maryland, 2023 Stream stage, stream temperature, and climate metrics for 30 streams spanning land use and management gradients in a mixed agricultural region in Pennsylvania and Maryland, 2023
This data release contains summary metrics describing stream stage, stream water temperature, and short-term climate conditions (daily precipitation and air temperature) for 30 streams spanning gradients of forest and agricultural land uses and the implementation of agricultural best management practices in a mixed agricultural region in Pennsylvania and Maryland, USA. This setting is...

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered conventional oil and gas resources of the Santos Basin, Campos Basin, and Espírito Santo Basin provinces of Brazil. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment NAGA Project for...
Paleomagnetic Directional Data from 194 sites on Hualalai Volcano, Hawaii Paleomagnetic Directional Data from 194 sites on Hualalai Volcano, Hawaii
Paleomagnetic samples were taken at 194 sites on Hualalai Volcano to obtain characteristic mean remanent magnetic directions using a standard protocol (McElhinny, 1973). Eight (8) to twelve (12) cores were taken at each site with a portable, water-cooled, diamond-coring drill, and oriented in the field exclusively with a suncompass. Measurements were conducted on both a spinner...
