DATA RELEASE Part 2: Optical luminescence dating of Bradley Lake, Oregon, tsunami deposits, analytical data for: A maximum rupture model for the central and southern Cascadia subduction zone-reassessing ages for coastal evidence of megathrust earthquakes DATA RELEASE Part 2: Optical luminescence dating of Bradley Lake, Oregon, tsunami deposits, analytical data for: A maximum rupture model for the central and southern Cascadia subduction zone-reassessing ages for coastal evidence of megathrust earthquakes
The following report summarizes the dating results from Bradley Lake, Oregon. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose determination, and datingrelated calculations. We recommend that this report be included as the supplementary...
Data Release Sediment and water column flux data from the Fox Rivermouth (Green Bay, WI; 2017) Data Release Sediment and water column flux data from the Fox Rivermouth (Green Bay, WI; 2017)
These are data associated with water column incubation experiments performed in the Fox rivermouth. The Fox River is a Lake Michigan tributary that enters Green Bay. These experiments are used to measure the transformation of inorganic and total dissolved nutrients occurring in the surface water of the rivermouth. Experiments had light and dark treatments, and some experiments were...
Data release: Process-based predictions of lake water temperature in the Midwest US Data release: Process-based predictions of lake water temperature in the Midwest US
Climate change has been shown to influence lake temperatures in different ways. To better understand the diversity of lake responses to climate change and give managers tools to manage individual lakes, we focused on improving prediction accuracy for daily water temperature profiles in 7,150 lakes in Minnesota and Wisconsin during 1980-2019. The data are organized into these items...
Data release: Walleye Thermal Optical Habitat Area (TOHA) of selected Minnesota lakes Data release: Walleye Thermal Optical Habitat Area (TOHA) of selected Minnesota lakes
Climate change and land use change have been shown to influence lake temperatures and water clarity in different ways. To better understand the diversity of lake responses to climate change and give managers tools to manage individual lakes, we focused on improving prediction accuracy for daily water temperature profiles and optical habitat in 881 lakes in Minnesota during 1980-2018. The...
Data set for a mesocosm to field assessment of the ecological risks associated with neonicotinoids in US streams Data set for a mesocosm to field assessment of the ecological risks associated with neonicotinoids in US streams
Neonicotinoids, a widely used class of insecticide, have been found in surface waters globally. They pose a risk to non-target species found in aquatic environments such as aquatic macroinvertebrates. To better understand the effects of the neonicotinoids imidacloprid, clothianidin and their mixtures on aquatic communities we ran a 30 day mesocosm test. Rock trays were colonized with...
Data Sets for Simulation of Migration of Injected Wastewater with High Levels of Ammonia in a Saline Aquifer in South Florida, using SEAWAT v 4 Data Sets for Simulation of Migration of Injected Wastewater with High Levels of Ammonia in a Saline Aquifer in South Florida, using SEAWAT v 4
This data set provides the SEAWAT - version 4 model input files used to simulate the transport of the injected fresh wastewater with high levels of ammonia in a saline aquifer in south Florida, from January 1983 to December 2013. Initial conditions for January 1983 are calculated in subdirectory \model\unigrid_link where steady-state conditions are assumed. Files needed to simulate...
Data sets for: Sampling for Per- and Polyfluoroalkyl Substances (PFAS) by the Groundwater Ambient Monitoring and Assessment Priority Basin Project (GAMA-PBP) Data sets for: Sampling for Per- and Polyfluoroalkyl Substances (PFAS) by the Groundwater Ambient Monitoring and Assessment Priority Basin Project (GAMA-PBP)
The U.S. Geological Survey Groundwater Ambient Monitoring and Assessment-Priority Basin Project (USGS GAMA-PBP) collected samples to be analyzed for per-and polyfluoroalkyl substances (PFAS) from domestic and public supply wells from May 2019 to September 2020. The datasets presented here include identification of the 28 PFAS constituents monitored by the project, Identification and...
Data sets of actual evapotranspiration rates from 2000 to 2017 for basins in Florida and parts of Alabama and Georgia, calculated using the water-balance method, the bias-corrected Operational Simplified Surface Energy Balance (SSEBop) model, and the and Data sets of actual evapotranspiration rates from 2000 to 2017 for basins in Florida and parts of Alabama and Georgia, calculated using the water-balance method, the bias-corrected Operational Simplified Surface Energy Balance (SSEBop) model, and the and
Annual actual evapotranspiration (ETa) rates in 55 basins in Florida and parts of Alabama and Georgia were evaluated for 2000–17 using the Operational Simplified Surface Energy Balance (SSEBop) model at about a one-square kilometer resolution (Sepúlveda, 2021). SSEBop ETa rates were bias corrected on the basis of ETa rates computed from weather observations at 24 micrometeorological
Data supporting the 2018 geomorphic survey of North Fork Eagle Creek, New Mexico Data supporting the 2018 geomorphic survey of North Fork Eagle Creek, New Mexico
This U.S. Geological Survey (USGS) data release contains results from the 2018 geomorphic survey of North Fork Eagle Creek, New Mexico. The 2018 geomorphic survey was conducted by the USGS, in cooperation with the Village of Ruidoso, New Mexico, and is the second in a planned series of five annual geomorphic surveys of the stream reach located between the North Fork Eagle Creek near Alto...
Data to Incorporate Water Quality Analysis into Navigation Assessments as Demonstrated in the Mississippi River Basin Data to Incorporate Water Quality Analysis into Navigation Assessments as Demonstrated in the Mississippi River Basin
This data release includes estimates of annual and monthly mean concentrations and fluxes for nitrate plus nitrite, orthophosphate and suspended sediment for nine sites in the Mississippi River Basin (MRB) produced using the Weighted Regressions on Time, Discharge, and Season (WRTDS) model (Hirsch and De Cicco, 2015). It also includes a model archive (R scripts and readMe file) used to...
Data used in projected air and water temperatures for selected regions of the upper San Francisco Estuary and Yolo Bypass under 20 scenarios of climate change 2020-2099 Data used in projected air and water temperatures for selected regions of the upper San Francisco Estuary and Yolo Bypass under 20 scenarios of climate change 2020-2099
Understanding the effects of climate change is a substantial challenge in estuarine systems because the mixing of freshwater and ocean water adds complexity to climate change projections. Such climate change projections have been conducted in the San Francisco Estuary as part of the U.S. Geological Survey's CASCaDE Project. In this project, we assessed downscaled air temperature data...
Data used in projected flow analysis in Yolo Bypass under 20 scenarios of climate change Data used in projected flow analysis in Yolo Bypass under 20 scenarios of climate change
Yolo Bypass is an ecological feature of the Bay-Delta ecosystem in California that provides floodplain habitat for spawning and rearing of Sacramento Splittail (Pogonichthys macrolepidotus) and rearing of juvenile Chinook Salmon (Oncorhynchus tshawytscha) when inundated. We used outputs from 10 climate change models for two Representative Concentration Pathways (RCPs) for greenhouse gas
