SHRIMP-RG U-Pb zircon geochronology and geochemistry, and whole-rock geochemistry and radioisotope data of select samples from southern California and Arizona, and northern Mexico SHRIMP-RG U-Pb zircon geochronology and geochemistry, and whole-rock geochemistry and radioisotope data of select samples from southern California and Arizona, and northern Mexico
This dataset accompanies proposed publication, "Tectonic disruption of the Proterozoic Yavapai-Matzatzal Province boundary near Sierra Hornaday, northwest Sonora", to be published in a Geological Society of America publication, which will report zircon SHRIMP-RG U-Pb ages and Sm-Nd whole rock isotope analyses to map the path of the Yavapai-Matzatzal province boundary across southwest...
Þingmúli Volcanic Complex, eastern Iceland: Pb, Sr, and Nd isotopic data, 2024 Þingmúli Volcanic Complex, eastern Iceland: Pb, Sr, and Nd isotopic data, 2024
This dataset consists of seven lava samples that were analyzed for Pb, Sr, and Nd isotopes. The dataset accompanies the planned publication, ‘The geochemical and petrogenetic evolution of Þingmúli central volcano: Insights to magma processes in Iceland’, as well as planned future publications on this volcanic complex. Pb, Sr, and Nd isotope data were used for this study to determine...
Flood frequency for three streamgages operated by the U.S. Geological Survey in the Black River basin in southeastern Missouri and northeastern Arkansas Flood frequency for three streamgages operated by the U.S. Geological Survey in the Black River basin in southeastern Missouri and northeastern Arkansas
Flood-frequency analyses were conducted for three streamgages operated by the U.S. Geological Survey (USGS) in the Black River basin of southeastern Missouri (MO) and northeastern Arkansas (AR): 07064000, Black River near Corning, AR; 07068000, Current River at Doniphan, MO; and 07069000, Black River at Pocahontas, AR. Results from the analyses will be used for design purposes by the...
Data describing the use of a newly identified staging area on Patuxent River Naval Air Station by banded Common Terns Data describing the use of a newly identified staging area on Patuxent River Naval Air Station by banded Common Terns
These data describe the demographic composition of Common Terns at a newly identified staging area on the Patuxent River Naval Air Station and evaluates the importance of this location to the local breeding population. Specifically, we sought to identify the number of individuals using this potential staging area, the origins of those individuals, and the relative importance of this...
Chesapeake Stream Team Field Sites, 2021-2024 Chesapeake Stream Team Field Sites, 2021-2024
Each year from 2021-2024, teams from the US Geological Survey and Virginia Tech studied 30 streams with a targeted gradient of land use and conservation practices across the Chesapeake Bay Watershed. The four years of the study cover the following geographic areas and land use characteristics: -Shenandoah Valley and Ridge pasture -Delmarva row crop -Pennsylvania and Maryland Piedmont...
Basin characteristics in support of generalized least-squares (GLS) regression for 136 USGS streamgages in urban areas in Tennessee and parts of Alabama, Georgia, Mississippi, North Carolina, and South Carolina (ver. 2.0, September 2025) Basin characteristics in support of generalized least-squares (GLS) regression for 136 USGS streamgages in urban areas in Tennessee and parts of Alabama, Georgia, Mississippi, North Carolina, and South Carolina (ver. 2.0, September 2025)
This data release contains a dataset of geospatial and tabular data used in support of a flood-frequency study of urban streams in Tennessee and parts of Alabama, Georgia, Mississippi, North Carolina, and South Carolina. The dataset includes data used in the development of generalized least-squares (GLS) regression equations for predicting streamflows at ungaged locations in the study...
