Pesticide Toxicity Index (PTI) and maximum Toxic Unit (TUmax) scores and information for fish, cladocerans, and benthic invertebrates from water samples collected at National Water Quality Network sites during Water Years 2013-2017 Pesticide Toxicity Index (PTI) and maximum Toxic Unit (TUmax) scores and information for fish, cladocerans, and benthic invertebrates from water samples collected at National Water Quality Network sites during Water Years 2013-2017
During 2013-2017, the U.S. Geological Survey, National Water-Quality Assessment (NAWQA) Project, collected water samples year-round from the National Water Quality Network - Rivers and Streams (NWQN) and reported on 221 pesticides at 72 sites across the US in agricultural, developed, and mixed land use watersheds. Pesticide Toxicity Index (PTI) scores, a screening-level tool that uses an...
Tabular data for selected items from the Census of Agriculture for the period 1950-2017 for counties in the conterminous United States Tabular data for selected items from the Census of Agriculture for the period 1950-2017 for counties in the conterminous United States
This product provides tabular data from the U.S. Department of Agriculture (USDA) Census of Agriculture for selected items for the period 1950-2017 for counties in the conterminous United States. Data from 1950-2012 are taken from LaMotte (2015) and 2017 data are retrieved from the USDA QuickStats online tool. Data which are withheld in the Census of Agriculture are filled with estimates...
Geochronologic data from xenoliths near the Stillwater Complex, Montana Geochronologic data from xenoliths near the Stillwater Complex, Montana
The Archean Stillwater Complex, a layered ultramafic-to-mafic intrusion, is exposed along the northern side of the Beartooth Mountains in Montana. To the north of the Stillwater outcrops, a gravity anomaly is located where Phanerozoic rocks may unconformably overlie the complex. These Phanerozoic rocks are intruded by Cretaceous plutons that have gabbroid inclusions that look like...
Failed Brown Treesnake bait cartridges from an aerially application in Guam, 2018 Failed Brown Treesnake bait cartridges from an aerially application in Guam, 2018
The dataset contains 6 columns of data collected during line transect surveys (Line) that evaluated bait cartridge efficacy for Brown Treesnake control on Guam. Two-person teams recorded all bait cartridges observed while walking the center line of transects in the Habitat Management Unit (HMU). Perpendicular distance (DIST (m)) to cartridges from center line was measured to the nearest...
Tops file for the Niobrara interval of the Upper Cretaceous Cody Shale and associated strata in the Bighorn Basin, Wyoming Tops file for the Niobrara interval of the Upper Cretaceous Cody Shale and associated strata in the Bighorn Basin, Wyoming
The Bighorn Basin is a large Laramide structural and sedimentary basin that encompasses about 10,400 square miles in north-central Wyoming and south-central Montana (fig. 1). The basin is bounded on the northeast by the Pryor uplift, on the east by the Bighorn uplift and on the south by the Owl Creek uplift. The northern margin is formed by a zone of faulting and folding referred to as...
Data on interannual seed set variation, weather, and reproductive traits for global plants Data on interannual seed set variation, weather, and reproductive traits for global plants
Data were collected on seed production dynamics of long-lived plants, reproductive plant traits of those plant species, and weather variability for sites where those species live. Data include the coefficient of variation in seed production over time, the variation (coefficient of variation or standard deviation) in weather over years, and reproductive traits such as pollination mode and...
