Sediment grain size from the Elwha River, Washington, 2006 to 2022 (ver. 2.0, July 2025)

The grain size of sediment on the riverbed was measured during 21 surveys on the Elwha River, Washington, between 2006 and 2022. Most data were collected along the same transects where channel topography was measured (see related child item in this data release with river-channel topography). Measurements of sediment ranging from medium sand to boulders were made using the CobbleCam digital photographic technique (Warrick and others, 2009), which uses a calibrated autocorrelation algorithm (Rubin, 2004) to calculate the mean grain size of sediment from pixels in downward-looking digital photographs. This technique yields grain-size values accurate to within 14 percent of those obtained by pebble counting (Wolman, 1954; Warrick and others, 2009). For samples finer than medium sand, we measured grain size using a Coulter laser particle-size analyzer at the USGS laboratory in Santa Cruz, California. Grain size was measured along subaerial portions of the survey transects within the bankfull channel. We also measured grain size of some sediment deposited after dam removal that did not coincide with survey transects (these sample locations are labeled “OffTransect” in the data file).

Climate, hydrology and riparian vegetation composition data, Grand Canyon, Arizona

These data were compiled for monitoring riparian vegetation change along the Colorado River. This file contains data recorded at 42 sandbars between Lees Ferry and Diamond Creek, AZ, which are sampled for both geomorphic and vegetation change annually. Field data contained here were collected from 2012 to 2016 in September and October of each year. Plant species cover values in 5441 1m^2 quadrat frames, locations and elevations of those sampling frames, slope and aspect, sample dates, temperature and precipitation data, and flood frequency parameters were either recorded in the field or calculated. Annual and seasonal climate variables were estimated from eight weather stations distributed along the river corridor from data aquired from Caster et al. 2014. Data collected between 1 February 2008 and 31 January 2011 were used, as the greatest number of weather stations were recording data with the fewest data gaps during this time. Data were linearly interpolated to sandbars lacking weather data based on distance from adjacent weather stations. Available climate variables included minimum and maximum annual temperature; mean annual, winter (November - April) and monsoon (May - October) precipitation; and mean annual humidity. Inundation and depth to water table were estimated for each plot using plot elevation (acquired from Kaplinski et al. 2014), the 15-minute hydrograph from Glen Canyon Dam (https://www.gcmrc.gov/discharge_qw_sediment/?), and the stage calculator developed for sandbars by Hazel et al. (2006). Discharge data from the 365 days preceding the vegetation surveys were used to calculate the proportion of that year, and the maximum number of contiguous days in which a plot was inundated; minimum, mean and maximum inundation depth; and elevation above river stage at 566m3s-1 (average daily peak flow).

Lake St. Joseph

Nutrient and phytoplankton data indicate poor environmental health in four oxbow lakes in central Louisiana suggesting that long-term agriculture practices and increases in shoreline development have accelerated eutrophication. Surface-water quality and phytoplankton indicators of eutrophication were examined at Lake Bruin, Lake St. John, Lake St. Joseph, and False River Lake along an eutrophication gradient. These oxbow lakes are cut-off meanders of the Mississippi River that do not receive overbank flow from the river due to the levee system built in the early twentieth century. Oxbows have formed at various times in the last few hundred years as the Mississippi River carves a more efficient hydrologic route to the Gulf of Mexico and exhibit a succession of stages in lake evolution, from deep and oligotrophic to shallow and eutrophic.
Water-quality samples were collected three times per year: once in late spring, once in late summer-early fall, and once in winter. Water samples were analyzed for major ions, nutrients, suspended sediments, pesticides, dissolved organic carbon, and chlorophyll. At each site, physiochemical properties (water temperature, specific conductance, dissolved oxygen, and pH) were recorded at multiple depths within a single vertical profile. Phytoplankton community samples and cyanotoxin samples were collected from the photic zone at the time of water-quality sample collection at one site per lake. This data release provides water quality profile and phytoplankton data for these lakes.

HyCReWW database: A hybrid coral reef wave and water level metamodel

We developed the HyCReWW metamodel to predict wave run-up under a wide range of coral reef morphometric and offshore forcing characteristics. Due to the complexity and high dimensionality of the problem, we assumed an idealized one-dimensional reef profile, characterized by seven primary parameters. XBeach Non-Hydrostatic was chosen to create the synthetic dataset and Radial Basis Functions implemented in Matlab were chosen for interpolation. Results demonstrate the applicability of the metamodel to obtain fast and accurate results of wave run-up for a large range of intrinsic coral reef morphologic and extrinsic hydrodynamic forcing parameters, offering a useful tool for risk management and early warning systems.

Groundwater Usage for Public Supply by County in the Glaciated Conterminous United States

The Groundwater Usage for Public Supply dataset contains attributes pertaining to groundwater use in the glaciated conterminous United States summarized by county. The attributes were computed from total groundwater usage by county compiled by Maupin and others (2010), and from inventories of water-use records for 71,267 public water-supply systems by Buchwald and others (in press). Source aquifers (Quaternary sediments or bedrock) were assigned for the public water-supply systems based on reported data (e.g., well construction records, aquifer delineation maps), or based on well depth and the Quaternary sediment thickness. Water usage rates are reported on an average annual, areal basis in units of millimeters per year, to facilitate comparison with estimated recharge rates from Westenbroek and others (in press).

Dataset for 2013 Creek Fire Research Points, Pre- and Post-Fire Data, U.S. Geological Survey

The practice of fire suppression across the western United States over the past century has led to dense forests, and when coupled with drought has contributed to an increase in large and destructive wildfires. Forest management efforts aimed at reducing flammable fuels through various fuel treatments can help to restore frequent fire regimes and increase forest resilience. Our research examines how different fuel treatments influenced burn severity and post-fire vegetative stand dynamics on the San Carlos Apache Reservation, in east-central Arizona, U.S.A. Our methods included the use of multitemporal remote sensing data and cloud computing to evaluate burn severity and post-fire vegetation conditions as well as statistical analyses. We investigated how forest thinning, commercial harvesting, prescribed burning, and resource benefit burning (managed wildfire) related to satellite measured burn severity (the difference Normalized Burn Ratio – dNBR) following the 2013 Creek Fire and used spectral measures of post-fire stand dynamics to track changes in land surface characteristics (i.e., brightness, greenness and wetness). This dataset includes all of the attribute information for each point, including if the location of the point intersects a treatment type or combination of treatments as well as a KML file showing the location of each point.

Fish data collected during 2015 and 2016 at 9 sites at the Ten Thousand Islands National Wildlife Refuge, Florida

Field sampling occurred at locations within Ten Thousand Islands National Wildlife Refuge on three transects along the natural salinity gradient of increasing salinity to the coastal south. We used three replicates per tier (east-west) for a total of nine sampling sites. Sites were approximately 1300 m apart in all directions. Sampling events occurred every 3–4 weeks from January to May for 7 sampling events in 2015 and 5 in 2016. These dates were selected to capture signals of the natural variation in water levels and salinity that occur during the transition from the wet season to the dry season. Fish traps were deployed at each of the nine sites and then retrieved the following day, allowing 24 hours soak time. Two minnow traps (Gee Minnow Trap; 22.9 x 44.5 cm, 0.6 cm mesh, 1.9 cm diameter opening) and two Breder traps (15 cm x 15 cm x 30 cm, 12 mm opening width, 15 cm opening height) were placed at each sampling site because the two trap types have the potential to catch different fish species.
