USGS National and Global Oil and Gas Assessment Project-West Siberian Basin Province of Russia: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project-West Siberian Basin Province of Russia: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables
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 West Siberian Province in Russia. The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit...
Caloosahatchee River Nutrient Enrichment Mesocosms: Phytoplankton Taxonomic Quantification September 2019, June 2020, September 2020, February 2021 Caloosahatchee River Nutrient Enrichment Mesocosms: Phytoplankton Taxonomic Quantification September 2019, June 2020, September 2020, February 2021
An interdisciplinary and multiagency study was undertaken to study harmful algal bloom (HAB) dynamics on the Caloosahatchee River, which drains to the west from Lake Okeechobee into the Gulf of Mexico. Algae and cyanobacteria play crucial roles in aquatic ecosystems, but under favorable environmental conditions certain taxa may experience population growth booms resulting in HABs. Four...
10-year (2003-2012) bird and vegetation data collected at wind facilities in North Dakota and South Dakota 10-year (2003-2012) bird and vegetation data collected at wind facilities in North Dakota and South Dakota
This data release contains eight datasets that represent the entirety of the data collected for a study that examined breeding-bird densities in native mixed-grass prairie from 2003 to 2012 at and adjacent to wind facilities in North Dakota and South Dakota, USA. Data were collected to determine breeding-bird density per 100 hectares (ha) by distance bands from turbines and by excluding...

These data include geochemical analyses of rock, mine waste, sediment, and soil samples collected from the Aynak copper deposit, Logar Province, Afghanistan in 2019. In addition, these data include geochemical analyses of water samples collected from the Aynak copper deposit, Logar Province, Afghanistan in 2019.
Spatial and temporal surveys of salmon eDNA in Seattle urban creeks, Washington, 2018 - 2020 Spatial and temporal surveys of salmon eDNA in Seattle urban creeks, Washington, 2018 - 2020
The data support a study that surveyed the spatial and temporal distribution of salmon eDNA in Seattle urban creeks, Washington, 2018 - 2020. The metadata represent qPCR quantification cycle (Cq) values for Chinook salmon, coho salmon, and coastal cutthroat trout assays performed on water samples collected on specific days at specific sites on Thornton Creek, Taylor Creek, and Mapes...
Proximal and distal factors associated with the decline in secondary invertebrate prey production in the Colorado River, Glen Canyon, Arizona. Proximal and distal factors associated with the decline in secondary invertebrate prey production in the Colorado River, Glen Canyon, Arizona.
Using a bioenergetic model, demographic data for the Rainbow Trout (Oncorhynchus mykiss) population were compiled and used to estimate total prey consumption in the Colorado River, Glen Canyon , AZ. Additionally, other data including invertebrate diet, drift, and benthic measurements were used to make generalized estimates of daily production rates for the most common benthic...
