Field observation of wind waves (2019) along the Chincoteague Living Shoreline, Virginia Field observation of wind waves (2019) along the Chincoteague Living Shoreline, Virginia
This dataset contains measured (interval = 0.5 hour) wave height, peak wave period, water level, and water depth during March 1 to May 1, 2019, at five wave gage locations along the Chincoteague Living Shoreline, Virginia. These wave gages were sampled continuously at 10 Hz to take 20-min bursts every 30 min. These data were used for the analysis of wave attenuation along the oyster-reef...
The North American Freshwater Migratory Fish Database (NAFMFD): Characterizing the migratory life histories of freshwater fishes of Canada, the United States, and Mexico The North American Freshwater Migratory Fish Database (NAFMFD): Characterizing the migratory life histories of freshwater fishes of Canada, the United States, and Mexico
We developed the North American Freshwater Migratory Fish Database (NAFMFD) that synthesizes current knowledge of migratory status, pattern, and behavior for native and non-native freshwater fish species throughout North America, including 1,241 species representing 79 families and 322 genera.
Input data, trained model data, and model outputs for predicting streamflow and base flow for the Mississippi Embayment Regional Study Area using a random forest model Input data, trained model data, and model outputs for predicting streamflow and base flow for the Mississippi Embayment Regional Study Area using a random forest model
This data release contains datasets developed for the purpose of training and applying random forest models to the Mississippi Embayment Regional Study Area. The random forest models are designed to predict total stream flow and baseflow as a function of a combination of watershed characteristics and monthly weather data. These datasets are associated with a report (SIR 2022-xxxx) and...
Above- and belowground biomass production, decomposition, and wetland elevation change in transitional coastal wetland communities exposed to elevated CO2 and sediment deposition: a mesocosm study from 2012 to 2014 Above- and belowground biomass production, decomposition, and wetland elevation change in transitional coastal wetland communities exposed to elevated CO2 and sediment deposition: a mesocosm study from 2012 to 2014
This data release includes belowground primary productivity, decomposition, and surface elevation change data from a two-year mesocosm experiment from 2012 to 2014. We conducted experimental greenhouse manipulations of atmospheric CO2 (double ambient CO2) and sediment deposition to simulate a land-falling hurricane under future climate conditions. Experimental greenhouse conditions...
Hydrologic metrics, biological metrics, R scripts, and model archives associated with regression analyses used to quantify relations between altered hydrological and biological responses in rivers of Minnesota, 1945-2015 Hydrologic metrics, biological metrics, R scripts, and model archives associated with regression analyses used to quantify relations between altered hydrological and biological responses in rivers of Minnesota, 1945-2015
The U.S. Geological Survey (USGS) and the Minnesota Pollution Control Agency (MPCA) conducted a cooperative study to develop linear regression models that quantify relations among 173 hydrologic explanatory metrics in five categories (duration, frequency, magnitude, rate-of-change, and timing) computed from streamgage records and 132 biological response metrics in six categories...
Aquatic Prey Resources in Response to Estuary Restoration in Willapa Bay, Washington (2014-2015) Aquatic Prey Resources in Response to Estuary Restoration in Willapa Bay, Washington (2014-2015)
The ongoing restoration of more than 200 hectares of estuarine habitat at Willapa National Wildlife Refuge, southwestern Washington, is expected to benefit a variety of species, including salmonids that use estuarine and tidal marshes as rearing and feeding areas as well as migratory waterbirds. During March through June 2014 and 2015, this study was initiated to assess aquatic prey...
Database for the Geologic Map and Structure Sections of the Clear Lake Volcanics, Northern California Database for the Geologic Map and Structure Sections of the Clear Lake Volcanics, Northern California
This geologic map database is a reproduction of U.S. Geological Survey Miscellaneous Investigations Map I–2362: “Geologic Map and Structure Sections of the Clear Lake Volcanics, Northern California” (Hearn, Donnelly-Nolan, and Goff, 1995). The database consists of a geologic map, three structural cross sections and a table of petrographic data for each map unit by mineral type, abundance...
Growth and Capture-Mark-Recapture Data for San Francisco Gartersnakes, Thamnophis sirtalis tetrataenia, in San Mateo County, California from 2007 to 2020 Growth and Capture-Mark-Recapture Data for San Francisco Gartersnakes, Thamnophis sirtalis tetrataenia, in San Mateo County, California from 2007 to 2020
This dataset includes records of captures of San Francisco gartersnakes (Thamnophis sirtalis tetrataenia) collected at five sites from 2007 to 2020. The data include measurements of snake snout-vent length to estimate growth patterns, snake sex, and the record of all captures of individual snakes for estimating capture probability, availability for capture, and survival. These data...
Argon data for HD-B1 intercalibration Argon data for HD-B1 intercalibration
This data release includes 40Ar/39Ar intercalibration data from the U.S. Geological Survey for neutron fluence monitors HD-B1 (Heidelberg biotite) and FCs (Fish Canyon sanidine). Potassium-bearing mineral grains were analyzed by argon geochronology at the U.S. Geological Survey Argon Geochronology Laboratory in Denver, Colorado. These data provide intercalibration information between the...
Velocity and Bathymetric Data near Outlet Structures for the City of Omaha Water Resource Recovery Facilities on the Missouri River, 2020 Velocity and Bathymetric Data near Outlet Structures for the City of Omaha Water Resource Recovery Facilities on the Missouri River, 2020
These data sets were derived from surveys at the Missouri River and Papillion Creek Water Resource Recovery Facility outfalls on the Missouri River. Each site had three transects, one at the outfall, one 45.7 meters upstream of the outfall and one 45.7 meters downstream of the outfall. Velocity and depth data were collected using an acoustic Doppler current profiler at each transect...
Seepage-run discharge measurements, September 8, 2021, He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i Seepage-run discharge measurements, September 8, 2021, He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i
This data release contains a comma-delimited ascii file of nine discrete discharge measurements made at sites along selected reaches of He'eia Stream and 'Ioleka'a Stream, O'ahu, Hawai'i, on September 8, 2021. These discrete discharge measurements form what is commonly referred to as a "seepage run." The intent of the seepage run is to quantify the spatial distribution of streamflow...
