Quantitative polymerase chain reaction (qPCR) cyanotoxin data for 21 sites on Lake Okeechobee and the Okeechobee waterway, Florida, USA collected monthly from March 2019 through October 2021 Quantitative polymerase chain reaction (qPCR) cyanotoxin data for 21 sites on Lake Okeechobee and the Okeechobee waterway, Florida, USA collected monthly from March 2019 through October 2021
Quantitative polymerase chain reaction (qPCR) data were compiled for the biosynthesis genes of five toxins of interest produced by cyanobacteria as well as an internal control. Sample deoxyribonucleic acid (DNA) were collected from 21 sites which includes 17 sites from Lake Okeechobee, and four sites from the Caloosahatchee River and the St. Lucie River. Samples were collected on a...
Estimated Nitrogen, Phosphorus, and Sediment Load Reductions from Best Management Practices in the Chesapeake Bay Watershed between 1985 and 2020 Estimated Nitrogen, Phosphorus, and Sediment Load Reductions from Best Management Practices in the Chesapeake Bay Watershed between 1985 and 2020
To estimate changes in nitrogen, phosphorus, and sediment loads from technologies and management practices (TMPs), the Chesapeake Bay Program Partnership's CAST model was used to run scenarios with and without TMPs for years between 1985 and 2020 for the Chesapeake Bay watershed. Scenarios were run using the native model segmentation of land-river segments and downscaled to the National
Southwestern Willow Flycatcher (Empidonax traillii extimus) Surveys and Nest Monitoring in San Diego County, California (ver. 5.0, December 2025) Southwestern Willow Flycatcher (Empidonax traillii extimus) Surveys and Nest Monitoring in San Diego County, California (ver. 5.0, December 2025)
Data presented are results of surveys and monitoring for Southwestern Willow Flycatcher (Empidonax traillii extimus) in San Diego County, California. These data were collected to assess Southwestern Willow Flycatcher abundance and distribution in San Diego County. Surveys were conducted in various years at 33 locations along 10 drainages in San Diego County, including portions of Agua...

This data release contains the boundaries of assessment units, assessment input data tables and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources in the Paleozoic petroleum systems of the Central European Basin System. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas...
Data describing infection status and movement ecology of North American waterfowl Data describing infection status and movement ecology of North American waterfowl
These data, which support a USGS authored manuscript, describe how active and previous previous infection with avian influenza impacts the movement ecology of several wild waterfowl species that overwinter in California. Results varied by species and demonstrate that the relationships between avian influenza infection and wild bird movements are context- and species-dependent.
