COAWST model of Barnegat Bay creeks to demonstrate marsh dynamics COAWST model of Barnegat Bay creeks to demonstrate marsh dynamics
The COAWST (Coupled Ocean-Atmosphere-Wave-Sediment Transport) modeling framework was extended to add two key processes that affect marshes, erosion due to lateral wave thrust (LWT) and vertical accretion due to biomass productivity. The testing of the combined effects of integrating these two processes was done by modeling marsh complexes within Forsythe National Wildlife Refuge and the...
Random forest regression model and prediction rasters of fluoride in groundwater in basin-fill aquifers of western United States Random forest regression model and prediction rasters of fluoride in groundwater in basin-fill aquifers of western United States
A random forest regression (RFR) model was developed to predict groundwater fluoride concentrations in four western United Stated principal aquifers - California Coastal basin-fill aquifers, Central Valley aquifer system, Basin and Range basin-fill aquifers, and the Rio Grande aquifer system. The selected basin-fill aquifers are a vital resource for drinking-water supplies. The RFR model...
Favorability of environmental conditions for coral reefs in Guam and American Samoa under multiple climate scenarios Favorability of environmental conditions for coral reefs in Guam and American Samoa under multiple climate scenarios
This dataset consists of raster geotiff outputs of relative environmental favorability for coral growth and survival in the United States territories of Guam and American Samoa across 3 climate scenarios: Present, Intermediate Emissions (Representative Concentration Pathway 4.5), and Worst Case Emissions (Representative Concentration Pathway 4.5). These datasets were generated from a...
Total organic carbon and pyrolysis analysis data for the U.S. Geological Survey Alcova AR-1-13 core hole, Natrona County, Wyoming Total organic carbon and pyrolysis analysis data for the U.S. Geological Survey Alcova AR-1-13 core hole, Natrona County, Wyoming
In 2013 the U.S. Geological Survey (USGS) drilled a continuous core in the southeastern part of the Wind River Basin, Wyoming to evaluate the source rock potential of the Lower and lowermost Upper Cretaceous marine shales . The well, named the Alcova Reservoir AR-1-13, located on the northeast flank of the Alcova anticline was spud in the lower part of the Frontier Formation and ended in...
2018 Eastern Lake Erie Shoreline 4-band orthophotos and mosaics 2018 Eastern Lake Erie Shoreline 4-band orthophotos and mosaics
High-resolution digital aerial imagery was collected on August 24, 2018, with an 80-megapixel Phase One iXU-R 180 natural color aerial camera co-mounted with a Phase One iXU-RS 160 achromatic aerial camera. Software co-registers the simultaneously collected images to create 4-band imagery that can be displayed in either true color (RGB) or color-infrared (CIR) format. The camera system...
Data for Machine Learning Predictions of Nitrate in Groundwater Used for Drinking Supply in the Conterminous United States Data for Machine Learning Predictions of Nitrate in Groundwater Used for Drinking Supply in the Conterminous United States
A three-dimensional extreme gradient boosting (XGB) machine learning model was developed to predict the distribution of nitrate in groundwater across the conterminous United States (CONUS). Nitrate was predicted at a 1-square-kilometer (km) resolution for two drinking water zones, each of variable depth, one for domestic supply and one for public supply. The model used measured nitrate
An updated X-ray diffractogram library of geologic materials An updated X-ray diffractogram library of geologic materials
The X-ray diffraction (XRD) pattern library presented here is intended for qualitative or quantitative mineralogical analysis of geologic materials. The original collection of 169 reference diffractograms was released by Eberl (2003) as a part of RockJock, a USGS program for quantitative analysis of mineralogy, which included patterns of many of the major rock-forming minerals needed to...
Concentration of chemical constituents in lake sediments from selected coring locations on Lake Lanier, Georgia, May 2018 Concentration of chemical constituents in lake sediments from selected coring locations on Lake Lanier, Georgia, May 2018
The data herein were collected in support of a larger study in Gwinnett County, Georgia, on the potential impacts of on-site waste water treatment (septic systems) on Lake Lanier water quality. Until recently, a missing component in this assessment was the inclusion of historical sediment and associated nutrient accumulation data from the lake to place results in a broader context. To...
Water table depth, soil moisture, and meteorological data from Panola Mountain Research Watershed, 2017 - 2020 Water table depth, soil moisture, and meteorological data from Panola Mountain Research Watershed, 2017 - 2020
These data represent time-series of water table depth from nine monitoring wells, soil moisture from three depths at a single monitoring location, and meteorological data from a weather station at the Panola Mountain Research Watershed (PMRW) in Rockdale County Georgia. Water-level data were logged at a 5 minute interval. In total, the data span from April 2017 to April 2020 but some...
Monarch Butterfly patch and landscape data for Wisconsin, 2018-2019 Monarch Butterfly patch and landscape data for Wisconsin, 2018-2019
To ensure habitat restoration efforts are targeted towards areas maximizing monarch population growth, it is important to understand the effects of landscape heterogeneity on monarch occurrence in habitat patches (i.e. grasslands with milkweeds). Over two summers (2018-2019), monarch adults, larvae, and eggs were surveyed at sixty grassland sites in Wisconsin varying in patch size and...
R code: Landscape- and local-level variables associated with monarch breeding occurrence and abundance at patches in Wisconsin grasslands R code: Landscape- and local-level variables associated with monarch breeding occurrence and abundance at patches in Wisconsin grasslands
This code file accompanies a manuscript describing associations of monarch breeding occurrence and abundance with landscape and local characteristics at locations in northern and southern Wisconsin. Context for the study can be obtained from the manuscript (Bruce (nee Harnsberger), A.S., Thogmartin, W.E., Trosen, C., Oberhauser, K., and Gratton, C., In-Press, Landscape- and local- level...
SPARROW model inputs and simulated future baseflow for streams of the Upper Colorado River Basin SPARROW model inputs and simulated future baseflow for streams of the Upper Colorado River Basin
The U.S. Geological Survey's (USGS) SPAtially Referenced Regression On Watershed attributes (SPARROW) model was used to estimate baseflow changes from historical (1984 - 2012) to thirty-year periods centered around 2030, 2050, and 2080 under warm/wet, median, and hot/dry climatic conditions. SPARROW is a spatially explicit hybrid statistical and process-based model that estimates mean...
