Annual variation in summer phytoplankton communities influenced by river morphology and seasonal environmental conditions Annual variation in summer phytoplankton communities influenced by river morphology and seasonal environmental conditions
Phytoplankton samples were collected from the La Grange reach of the Illinois River from 2010-2020. Samples were collected from main channel, side channel and backwater areas. The following dataset includes phytoplankton community data (e.g., taxa, biovolume, cell counts, etc.). Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by...
Great Lakes seamless topobathymetric digital elevation models and shaded relief maps Great Lakes seamless topobathymetric digital elevation models and shaded relief maps
Modifications were made to existing great lakes topobathy data sets to interpolate areas of missing near shore elevation data. Areas with missing elevation data were not interpolated where there was low confidence in the underlying depth. This included rivers, canals, harbors, lakes, reservoirs, etc. Areas important for targeting Phragmites australis management often lie within these...
Anesthetic properties of carbon dioxide on native and invasive fishes Anesthetic properties of carbon dioxide on native and invasive fishes
This study evaluated the anesthetic properties of dissolved carbon dioxide on six fish species to determine its efficacy for use in sedating wild caught fish for surgeries. Phase I of this study aimed to inform induction time, recovery time, and short-term survival of fish using five different concentrations of carbon dioxide at one water temperature. Phase II determined the induction...
Acute Toxicity of Carbon Dioxide to Crayfish Acute Toxicity of Carbon Dioxide to Crayfish
This study evaluated the use of dissolved carbon dioxide as a control method for invasive crayfish. Five concentrations of CO2 were administered to twenty-four test tanks at a water temperature of 5°C. Initially, Red Swamp Crayfish (RSC; Procambarus clarkii) were intended to be the test species used in the study. However, problems with obtaining a healthy population of RSC occurred, so...
Fluid inclusion data for fluorite, smoky quartz, and calcite samples from the Bear Lodge alkaline complex, Wyoming Fluid inclusion data for fluorite, smoky quartz, and calcite samples from the Bear Lodge alkaline complex, Wyoming
This data release is a collection of quantitative and qualitative data for fluid inclusions in samples from the Bear Lodge alkaline complex, Wyoming. The dataset includes:microthermometry, Raman spectroscopy, noble gas spectroscopy, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), and energy dispersive X-ray analyses of fluid inclusions. For spatial context and...
Projections of Elevation and Mangrove Species Cover under Sea-Level Rise across Pohnpei, Federated States of Micronesia Projections of Elevation and Mangrove Species Cover under Sea-Level Rise across Pohnpei, Federated States of Micronesia
Future sea-level rise poses a risk to mangrove forests. To better understand potential vulnerability, we developed a numerical model of soil elevation for mangrove forests. We used the model to generate projections of elevation and mangrove forest composition change under six sea-level rise scenarios from 2020 through 2150. We employed a data-driven modeling approach, utilizing new and...
Diamondback terrapins and their potential diet isotope values and associated metadata collected 2018-2021 in St. Joseph Bay, Florida Diamondback terrapins and their potential diet isotope values and associated metadata collected 2018-2021 in St. Joseph Bay, Florida
These datasets contain the carbon and nitrogen stable isotope data from diamondback terrapin epidermis tissue and a variety of sampled prey items.
Fuels Data From Sequoia and Kings Canyon National Parks 2022 Fuels Data From Sequoia and Kings Canyon National Parks 2022
We established a network of 121 plots distributed within the 2020 SQF, 2020 Rattlesnake, and 2021 KNP complex fire footprints (extracted from Fire and Resource Assessment Program (FRAP), https://frap.fire.ca.gov), as well as outside the fire perimeters to provide an unburned comparison. These plots were combined from two projects: a fire and fuels study (F&F) and the USGS sequoia...
Preliminary Digital Database for the Portola 30' x 60' Geologic and Geophysical Map, California Preliminary Digital Database for the Portola 30' x 60' Geologic and Geophysical Map, California
This geospatial dataset compiles, in digital form, geologic and geophysical data for the Portola 30’x 60’ quadrangle, located in the northern Sierra Nevada, California. This geologic map of the Portola 30’x 60’ quadrangle integrates decades of published and unpublished mapping in the northern Sierra Nevada. In conjunction with geophysical data, including more than 1000 new gravity...
Historical sea turtle relocation trawling data in the southeast U.S. (1991 - 2024) Historical sea turtle relocation trawling data in the southeast U.S. (1991 - 2024)
The U.S. Geological Survey (USGS) Wetlands Aquatic Research Center worked alongside the U.S. Army Corps of Engineers (USACE) and Bureau of Ocean Energy Management (BOEM) to amalgamate over three decades of relocation trawling records. It is USACE's mission to provide safe, reliable, efficient , and environmentally sustainable waterborne transportation systems (channels, harbors, and...
Estimated aquifer distribution for private-domestic wells; estimated spatial distribution of the self-supplied domestic population for 2020 and 2010; and estimated monthly self-supplied domestic withdrawals of groundwater for the Virginia Coastal Plain Estimated aquifer distribution for private-domestic wells; estimated spatial distribution of the self-supplied domestic population for 2020 and 2010; and estimated monthly self-supplied domestic withdrawals of groundwater for the Virginia Coastal Plain
The USGS developed methods and results to improve estimation of the aquifer system, location, and quantity of private-domestic well groundwater withdrawals and the self-supplied domestic population of the Virginia Coastal Plain. This USGS data release includes (1) tabular datasets with the estimated aquifer distribution of 8,264 private-domestic wells aggregated by locality/county, USGS...
Piping plover adult breeding dispersal and annual survival in the northern Great Plains, USA, 2014 - 2019 Piping plover adult breeding dispersal and annual survival in the northern Great Plains, USA, 2014 - 2019
We present a tabular data set representing values used to evaluate intrinsic factors of breeding dispersal and annual survival for northern Great Plains piping plovers (Charadrius melodus) from 2014 – 2019. Data was collected on wetlands and on the Missouri River in North Dakota, South Dakota, and Montana. Data includes breeding state specific observations of adults. The associated...
