Chemistry Data from the Birney Test Site, Montana, 2018-2020 Chemistry Data from the Birney Test Site, Montana, 2018-2020
Data were collected to monitor geochemistry before and after an injection designed to stimulate microbial methanogenesis in the shallow Flowers-Goodale coal bed, near Birney in southeastern Montana. Waters from wells completed in the Flowers-Goodale, Nance, Knobloch, and Terret coalbeds at the Birney Test Site were sampled. Geochemical characterization of the water included non-purgeable...
Phytoplankton Data for Malheur Lake, Oregon, 2018-2020 Phytoplankton Data for Malheur Lake, Oregon, 2018-2020
Malheur Lake is a shallow, freshwater lake in southeastern Oregon. This data release includes phytoplankton data from three sites located in Malheur Lake collected from 8/8/2018 to 8/11/2020. For each sample collected, the phytoplankton were reported to the lowest taxonomic unit. Phytoplankton biovolume, algal cell concentration, and algal biomass concentration are included. All...
Field measurements of water depth from the American River near Fair Oaks, CA, October 19-21, 2020 Field measurements of water depth from the American River near Fair Oaks, CA, October 19-21, 2020
Field measurements of water depth were acquired from a reach of the American River at Sailor Bar, near Fair Oaks, California, October 19-21, 2020, to support research on remote sensing of water depth from satellite images. The depth measurements included in this data release were obtained via two different methods: 1) By wading the shallow channel margins with RTK GPS receivers and...
Field measurements of water depth from the Colorado River near Lees Ferry, AZ, March 16-18, 2021 Field measurements of water depth from the Colorado River near Lees Ferry, AZ, March 16-18, 2021
Field measurements of water depth were acquired from a reach of the Colorado River near Lees Ferry, Arizona, March16-18, 2021, to support research on remote sensing of water depth from satellite images. The depth measurements included in this data release were obtained along a series of cross-sections using a SonTek RiverSurveyor M9 acoustic Doppler current profiler (ADCP) deployed from...
Stormwater-quality data in the control and test catchments during the calibration and treatment phase of a leaf collection study in Madison, Fond du Lac, and Oshkosh, WI, from September 2016 through November 2019 Stormwater-quality data in the control and test catchments during the calibration and treatment phase of a leaf collection study in Madison, Fond du Lac, and Oshkosh, WI, from September 2016 through November 2019
The data set contains phosphorus and nitrogen concentrations and loads measured as part of a study to determine if, and by how much, removing leaves and other organic detritus from streets, through municipal leaf collection and street cleaning programs, could reduce nutrient contributions to local water bodies. Stormwater runoff was sampled in paired, medium-density, residential...
Multibeam echosounder, video observation, and derived benthic habitat data offshore of south-central California in support of the Bureau of Ocean Energy Management Cal DIG I, offshore alternative energy project Multibeam echosounder, video observation, and derived benthic habitat data offshore of south-central California in support of the Bureau of Ocean Energy Management Cal DIG I, offshore alternative energy project
Coastal and Marine Ecological Classification Standard (CMECS) geoform, substrate, and biotic component (also known as "biotope") GIS products were developed for the U.S. Exclusive Economic Zone of south-central California motivated by interest in development of offshore wind energy capacity and infrastructure. The lead agency responsible for planning and leasing in the Exclusive Economic...
