Results of Ecosystem Scale Selenium Modeling in Support of Site-Specific Guidelines Development for Lake Koocanusa, Montana, U.S.A., and British Columbia, Canada, 2020

This data release and accompanying spreadsheet illustrate the ecosystem scale selenium model for Lake Koocanusa described in USGS Open-File Report 2020-xxxx, "Understanding and Documenting the Scientific Basis of Selenium Ecological Protection in Support of Site-Specific Guidelines Development for Lake Koocanusa, Montana, U.S.A., and British Columbia, Canada." All report sections, equations, and tables referenced in this data release and spreadsheet are from that report, referred to hereafter as “the OFR.” Two models are described in the OFR.  Results for several different “runs” of this model with different model input parameters and assumptions are included in this data release.  The spreadsheet calculations that produced those results are also included with this data release. Model 1, IFM = Insect-to-fish model, summarized by Eq. 11: protective C(Se)dissolved = tissue guideline/TTFfish /[(TTFinvert1*invert fraction1) + (TTFinvert2*invert fraction2)]/SPM bioavailability fraction/(Kd/1,000). Model2, TFM = Trophic-fish model, summarized by Eq. 12: protective C(Se)dissolved = tissue guideline/TTFfishTL4/TTFfishTL3/[(TTFinvert1*invert fraction1) + (TTFinvert2*invert fraction2)]/SPM bioavailability fraction/(Kd/1,000). Model results are presented for the four representative IFM food webs described in Table 6 of the OFR, and for three representative TFM food webs described in Table 7 of the OFR.  “Generic” IFM and TMF modeling spreadsheets (consistent with Tables 8 and 9 of the OFR) are provided that implement the two models such that a user can establish their own modeling assumptions and view the results of the models with those assumptions.Finally, four alternative modeling scenarios and results specifically requested by the Montana Department of Environmental Quality, the cooperator in this work, are also presented here.

Data used to model and map arsenic concentration exceedances in private wells throughout the conterminous United States for human health studies

This data release contains data used to develop models and maps that estimate probabilities of exceeding various thresholds of arsenic concentrations in private domestic wells throughout the conterminous United States. Three boosted regression tree (BRT) models were developed separately to estimate the probability of private well arsenic concentrations exceeding 1, 5, and 10 micrograms per liter (µg/L).  A random forest (RF) model was developed to estimate the most probable arsenic concentration category (≤5, &gt;5 to ≤10, or &gt;10 µg/L).  The models use arsenic concentration data from private domestic wells located throughout the conterminous United States and independent variables that are available as geospatial data.  The models were used to produce maps that are included in this data release. 
The model input data (predictor variables) that were used to make the maps are within a zipped folder (Map_Input_Data.zip) that contains 85 tif-raster files, one for each model predictor variable.  The map probability estimates that are outputs from the model are in a zipped folder (Map_Output_Data.zip) that contains 13 tif-raster files, one model estimate map for each of the BRT models and four for the RF model, as well as 2 confidence interval maps for each BRT model.

Atomic Force Microscopy-based Infrared Spectroscopy Data within Immature Eagle Ford Shale at the Nanometer-scale

The nanoscale molecular composition of kerogen is a challenging parameter to characterize given the chemical and structural complexity exhibited by this important biopolymer. However, kerogen composition will strongly impact its reactivity and so is a critical parameter to understand petroleum generation processes during kerogen catagenesis. The recent advent of tip-enhanced analytical methods, such as atomic force microscopy-based infrared spectroscopy (AFM-IR), has allowed for the major compositional features of kerogen to be elucidated at spatial resolutions at or below 50 nm. Here we apply AFM-IR to examine inertinite, an important kerogen maceral type, from an immature Eagle Ford Shale sample. Our data show that the nanoscale molecular composition of the examined inertinite is: (i) less heterogeneous than other organic matter types from the Eagle Ford Shale and (ii) more hydrogen- and oxygen-rich than inertinite from the New Albany Shale at a similar stage of thermal maturity.

Magnetotelluric Data from the San Andreas Fault, Loma Prieta CA, 1989-1990

The U.S. Geological Survey (USGS) Geology, Geophysics and Geochemistry Science Center (GGGSC) collaborated with the USGS Science Analytics and Synthesis (SAS) team to preserve and release a subset of magnetotelluric data from the San Andreas Fault in Loma Prieta, California. The San Andreas Fault data were collected by the Branch of Geophysics, a precursor to the now GGGSC, between 1989 and 1994. The magnetotelluric data selected for this preservation project were collected in 1989 and 1990 using USGS portable truck mounted systems that measure the distribution of electrical conductivity beneath the surface of the earth. Truck mounted systems of this era output data to 3.5” discs, from which data were recovered and transformed to binary or ASCII formats using proprietary software. This USGS data release includes the original binary and ASCII data files and derivative EDI files (Wight, 1988), a common modern format for magnetotelluric modelling, created using Python-based software developed by the SAS team.

Colorado River Delta project: Growing Season Normalized Difference Vegetation Index (NDVI) Difference Maps

These operational land imager (OLI) value added data sets, maps, and associated ancillary data were compiled as part of an ongoing research aimed at quantifying the riparian vegetation greenness and water use in the lower Colorado River Delta in Mexico. In order to create trend and anomaly maps that characterize these ecosystems Vegetation Index (NDVI) time series imagery from Landsat OLI were acquired and processed over time and space along seven predefined reaches that capture different natural states and management conditions.
We used Landsat OLI 30m data as an improvement upon past studies that were based on coarser remote sensing data from the NASA MODIS sensor (250 m). The OLI 30m images provide better characterization and performance over these rather narrow riparian corridors. To capture the change over time we used a simple differencing technique that compares two annual average growing season VI cycles (limited to May-October).  These anomaly maps capture how the corridor vegetation health responds to both natural and anthropogenic changes.  We limited this study to the full OLI record (2013-2019) since we were interested in understanding the response to Minute 319 pulse flow of 2014. The difference maps are an ideal tool for capturing how the released water impacted vegetation immediately and over long time.
The Minute 319 pulse flow science team in collaboration with the University of Arizona have developed a data processing system to support this effort with focus on understanding how the riparian corridor is responding to these natural and anthropogenic stressors.
All data associated with this project were acquired from the LP-DAAC and pre-processed to remove and capture issues prior to further processing (see below) which involved reprojection to a common projection, masking to only retain the area of interest, quality analysis to discard poor data, and then value addition to generate the NDVI and the difference maps.  The data acquisition and analysis were performed at the University of Arizona VIP lab (vip.arizona.edu) using their large Linux cluster of computing and storage resources.  A mix of off the shelf software and specialized in-house tools were used to carry the different steps and analyses.

Colorado River Delta project: River reach (1-7) full timeseries period statistics computed for Landsat 5, Landsat 7 and Landsat 8 data.

These data were compiled for monitoring riparian zone trends and changes in the Lower Colorado Delta as part of the Minute 139 of the 1944 Water Treaty between the United States and Mexico. The quality and quantity of the Delta’s riparian and aquatic ecosystems have been dramatically reduced over the past century, due largely to significant alterations to natural hydrologic and sediment regimes. The Minute 319 Agreement states that 130 million cubic meters of water was to be released during the spring of 2014. Water was released from Morelos Dam at the Northern International Border (NIB) near Yuma, Arizona, to the river’s delta in Mexico, allowing water to reach the Gulf of California for the first time in 13 years since 2000. Our study evaluated the short and long-term effects of environmental flows to hydrological processes in this borderland delta region. Because of the landscape changes and the anticipated impacts of added water in 2014 from Minute 319 water release, we explored remote sensing-based change analysis techniques and data to develop time series data of the Colorado River delta riparian corridor vegetation greenness and water use since the year 2000. We divided the river into 7 Reaches (R1..R7) to separate between the different land covers, management conditions, and general geospatial and hydrological conditions. We generated a variety of vegetation index, ET, anomalies, and trends using time series for all reaches combined then separately. Our data shows Landsat and MODIS derived EVI and EVI2 as well as time-series data of ETLandsat-EVI (mm/day), using a modified (EVI mod) equation, and ETMODIS-EVI  with both EVI and then EVI 2 as the input variable to the ET algorithm were extremely consistent across sensors and methods and covaried well with vegetation, climate, and hydrological conditions of each reach and the whole region. These data represent statistics that were computed within each river reach (1-7) for the full timeseries period and for each raster dataset; Landsat 5 Continuity Data (Cont), Landsat 7 Continuity Data (Cont_L7), Landsat 7 NDVI data filtered using QA pixel information (Filter_L7), Landsat 5 and Landsat 8 NDVI data, filtered using QA and Long Term Average (Filter2), Landsat 7 NDVI data, filtered using QA and Long Term Average (Filter2_L7), Landsat 5 and Landsat 8 NDVI Data filtered using QA pixel information (Filtered), and Landsat 5 Continuity, Landsat 7 Continuity and Landsat 8 (MergeCont).

Debris-flow video files, Chalk Cliffs, Colorado, USA, 2017

Chalk Cliffs, located 8 miles southwest of Buena Vista, Colorado, is one of the most active debris-flow areas in the state (U.S. Geological Survey). Three stations were set up at Chalk Cliffs which are located sequentially along a channel draining the 0.3 km^2 study area. This data release includes videos of debris-flows and floods captured by high-definition cameras placed at four different locations along the study area at Chalk Cliffs during 2017. Near the Upper Station (Station 1) there are two cameras, one located at the bridge cross section at the channel (Bridge Camera) and another on the opposite side of the basin with a broad view of the channel (Wide-angle Camera). The third camera is located near Station 2 (Middle Camera), and the final camera (Firehose Camera) is located near the bottom of the channel. The attached figure "station_and_camera_locations.png" provides an overview figure with the location of the four cameras and three stations along the channel. The videos and their audio are used to record information on flow type and velocity of debris flows. They can also be used to interpret how the flow characteristics, such as sediment concentration, vary with time to compare to seismic observations. 
Video recording for all cameras is triggered using a rainfall threshold (Michel et al., 2019). The complete videos for all the cameras are downloaded manually during site visits.  More detailed information about the cameras and settings used can be found in the metadata file under “Process steps” in “Data quality information.”  
During 2017, several debris flows and floods were captured by the four cameras. The videos can currently be viewed in the individual ‘Child item’ pages accessible below. The ‘Child item’ pages contain either flood or debris flow video files for each camera described above.

The Basin Characterization Model - A monthly regional water balance software package (BCMv8) data release and model archive for hydrologic California (ver. 5.0, June 2025)

This data release accompanies the USGS Techniques and Methods report titled: "The Basin Characterization Model - A Regional Water Balance Software Package", and includes all necessary Basin Characterization Model version 8 (BCMv8) inputs and outputs for water years 1896 to 2024. The BCMv8 was refined from the previous BCMv65 version to improve the accuracy of the water-balance components, particularly the recharge estimate. The new version includes seven new features: (1) monthly vegetation-specific actual evapotranspiration (AET) for 65 vegetation types, (2) spatially distributed calibration coefficients for snow accumulation and snowmelt, (3) mapped soil organic matter, (4) soil hydraulic properties calculated from soil texture and soil organic matter (model simulations run using water content at field capacity of –0.01 megapascal (MPa) and wilting point of –6 MPa), (5) soil dry-out below wilting point at a rate driven by average statewide aridity, (6) a switch allowing for the incorporation of urban impermeable surfaces, and (7) internally calculated gaining and losing streams. The model has been run at a monthly time scale to calculate the unimpaired water balance for every 18-acre (270 by 270-meter) grid cell for all of California, including all basins draining into the state for water years 1896–2024.
