Modeling Escherichia coli in the Missouri River near Omaha, Nebraska, 2012-16: Model Inputs and Outputs Modeling Escherichia coli in the Missouri River near Omaha, Nebraska, 2012-16: Model Inputs and Outputs
This data release contains the inputs and outputs from the development of Escherichia coli (E. coli) concentration models for the four Missouri River sites near Omaha, Nebraska. Model development, models, and results are published in the associated U.S. Geological Survey (USGS) report Densmore and others, 2020. Load Estimator models (LOADEST) (Runkel and others, 2004) were developed from...
Historical produced water chemistry data compiled for selected oil fields in Los Angeles and Orange Counties, southern California Historical produced water chemistry data compiled for selected oil fields in Los Angeles and Orange Counties, southern California
This digital dataset contains historical geochemical and other information for 200 samples of produced water from 182 sites in 25 oil fields in Los Angeles and Orange Counties, southern California. Produced water is a term used in the oil industry to describe water that is produced as a byproduct along with the oil and gas. The locations from which these historical samples have been...
Ground Control Point Locations, Elevations and Photographs From North Topsail Beach and Camp Lejeune, North Carolina, June 2019 Ground Control Point Locations, Elevations and Photographs From North Topsail Beach and Camp Lejeune, North Carolina, June 2019
Scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center collected location data (horizontal and vertical coordinates) for 53 Ground Control Points (GCP) in North Topsail Beach and within the Camp Lejeune Marine Corps Base, North Carolina, in June 2019. These GCPs were used to georectify aerial imagery taken post-Hurricane Florence (landfall...
Microbial and chemical contaminant occurrence and concentration in groundwater and surface water proximal to large-scale poultry facilities and poultry litter, 2016 Microbial and chemical contaminant occurrence and concentration in groundwater and surface water proximal to large-scale poultry facilities and poultry litter, 2016
Chemical and biological results, quality assurance and quality control, and method information from groundwater, surface water, and litter samples, collected from nine locations in Iowa and one in Wisconsin in 2016. Thirteen groundwater, nine surface water, four poultry litter, and four QA/QC samples were collected. Samples were analyzed at U.S. Geological Survey laboratories; bacteria...
Demographic data from two chorus frog populations in Colorado Demographic data from two chorus frog populations in Colorado
We used 29 years of data on boreal chorus frogs at two sites to view life-history, estimate demographic parameters, assess weather-related covariates, and determine the magnitude of process variation in target parameters. Average estimates of survival probabilities were 0.51 (Standard error [SE]=0.04) and 0.43 (SE=0.04), and average estimates of recruitment probabilities were 0.64 (SE=0...
Data Release for Testing ecosystem accounting in the United States: A case study for the Southeast Data Release for Testing ecosystem accounting in the United States: A case study for the Southeast
Ecosystems benefit people in many ways, but these contributions do not appear in traditional national or corporate accounts so are often left out of policy- and decision-making. Ecosystem accounts, as formalized by the System of Environmental-Economic Accounting Experimental Ecosystem Accounts (SEEA EEA), track the extent and condition of ecosystem assets and the flows of ecosystem...
