Summary of Decadal No-Flow Fractions and Decadal L-Moments of Nonzero Streamflow Flow-Duration Curves for National Hydrography Dataset, Version 2 Catchments in the Southeastern United States, 1950 - 2010, at 12-digit Hydrologic Unit Code (HUC12) Pour Points

Censored and uncensored generalized additive models (GAMs) are developed from 955 U.S. Geological Survey streamflow-gaging stations (streamgages) to predict decadal statistics of streamflow. The streamgages are located on streams draining to the Gulf of Mexico. Decadal statistics include no-flow fractions and selected L-moments of nonzero streamflow for six decades (1950s—2000s). These statistics represent metrics of decadal flow-duration curves (dFDCs) derived from about 10 million daily mean streamflows. The L-moments include the mean, coefficient of L-variation, and the third through fifth L-moment ratios. The models are fit using watershed properties such as basin area and slope, decadal precipitation and temperature and decadal values of flood storage and urban development percentages. The GAMs then estimate decadal statistics for 8,988 prediction locations (stream reaches) coincident with outlets of level-12 hydrologic unit codes. Both the entire dataset (whole model) and leave-one-watershed-out model results are reported. No-flow fractions are censored data and Tobit extensions to GAMs are effective in estimation of ephemeral streamflow conditions. Uncensored GAMs conversely were used for estimation of the L-moments. The R language was used to pull and process the streamflow data, and the scripts can be found online at https://code.usgs.gov/water/restore/fdclmrpplo.

Combined Occurrence Frequency of Wind Speeds and Precipitation Amounts Conducive to Dust Dispersion from Disturbed Mine and Mill Sites in the United States, 2007–16

Dispersion of dust depends on many complex factors related to the nature of the disturbed materials, climate, dust control measures, and localized weather patterns. This dataset presents wind speed and rainfall as climate factors that influence dust dispersion. These two basic factors were identified as a subset of the many factors that can lead to dust dispersion. Arpacioglu and Er (2003) reviewed historical data from selected mine sites and suggested that days when the windspeed was at least 5.4 meters per second (m/s) at 10 meters above land surface and rainfall was less than 0.25 centimeter (cm) might lead to greater dust dispersion. Existing publicly available precipitation and wind speed data from NASA’s North American Land Data Assimilation System Phase 2 (NLDAS-2), reflecting climatic conditions over a 10-year period in the United States, were used to assess the number of days between 2007 and 2016 that meet these criteria. The resulting dust dispersion index data sets are intended to indicate areas that exhibit criteria that are most likely to disperse dust particulates and fugitive dusts from disturbed mine and mill sites.

Foothill Yellow-Legged Frog (Rana boylii) Monitoring and Assessment Data from the Trinity River, California (2013-2017)

A key objective of the Trinity River Restoration Program (TRRP) is maintaining and enhancing other wildlife populations through the restoration initiatives. For herpetological species, the foothill yellow-legged frog and western pond turtle have been identified as important species on which to focus monitoring efforts due to their status as California state-listed Species of Concern. As a result, considerable prior effort has focused on understanding the distribution and demography of these species, both on the main Trinity River and on the South Fork Trinity River as a comparison population (potentially representing pre-dam population status). These studies have highlighted differences in life-history traits of each species between the two rivers that may be due to conditions of the main Trinity River. For western pond turtle these traits include slow growth rates, smaller adult sizes, lower annual fecundity, and later age at maturity in comparison to South Fork Trinity River and other western pond turtles in the region. For foothill yellow-legged frogs, densities of egg masses are an order of magnitude lower on the main Trinity River in comparison to the South Fork Trinity River. Egg masses on the main Trinity River are also vulnerable to scour depending on the timing and volume of water released from the dam. TRRP is working to address these issues by including consideration of the impacts of water management decisions on these species, as well as taking habitat requirements into account in their channel rehabilitation work that is geared towards improving salmonid rearing habitat.

Brown Treesnake counts during visual encounter surveys at three walking paces, Guam 2016

We evaluated three walking paces to estimate (1) how snake detection rate per unit distance changes with increasing pace, and (2) how total number of snakes found by the end of a night of surveying varies with pace when the amount of surveying time per night is held constant. For a “fast” pace we searched the 220 meter-long transect in 10 minutes, corresponding to a walking pace of 1.32 km/h, whereas for a “medium” pace we searched 17.5 minutes, corresponding to a pace of approximately 0.75 km/h. The “slow” pace was the 30 minutes (0.44 km/h) the standard previously adopted for work on Guam.  Perch height and sizes of detected snakes were recorded for the three paces.

Relating tissue egg counts to eggs/g of spleen in Hawaiian green turtles

The present study proposes a new methodology for the quantification of parasite eggs in animal tissue. Quantification of parasites are important to understand epidemiology of spirorchiid infections in sea turtles, however different methodologies for quantifying Spirorchiidae eggs in turtle tissues have been used.  The most representative way to quantify Spirorchiidae burdens in tissues is counting eggs / g of tissue, however, this method is very laborious. As an alternative, we propose quantifying number of Spirorchiidae egg/ area of tissue on a microscope slide. We compared this method to number of eggs / slide, a common metric of egg burden in turtle tissues.  Both methods correlated well with eggs / g with eggs/mm^2 of tissue having better correlation.

Sensor data from natural release experiments conducted in May, 2017, at the USGS debris-flow flume, HJ Andrews Experimental Forest, Blue River, Oregon

The files consist of six .csv files, with two files for each of three experiments (2017_05_16, 2017_05_17, 2017_05_18). One of the two files contain high-resolution data (1000 Hz) collected during the period of slope failure only, and the other files contain low-resolution data (10 Hz) for the entire duration of an experiment. Each of these files contains multiple columns of data, with each column representing either a time measurement or the value of a physical quantity measured at that time (e.g., flow depth, pore pressure, normal stress, etc.). In addition, 289 pairs of images were extracted from two video cameras during the sediment failure on May 17 2017.

Louisiana Barrier Island Comprehensive Monitoring Program – 2008 habitat map, East Chenier Region (ver. 1.1, May 2020)

The Barrier Island Comprehensive Monitoring (BICM) program was developed by Louisiana’s Coastal Protection and Restoration Authority (CPRA) and is implemented as a component of the System Wide Assessment and Monitoring Program (SWAMP). The program uses both historical data and contemporary data collections to assess and monitor changes in the aerial and subaqueous extent of islands, habitat types, sediment texture and geotechnical properties, environmental processes, and vegetation composition. Examples of BICM datasets include still and video aerial photography for documenting shoreline changes, shoreline positions, habitat mapping, land change analyses, light detection and ranging (lidar) surveys for topographic elevations, single-beam and swath bathymetry, and sediment grab samples. For more information about the BICM program, see Kindinger and others (2013).
The U.S. Geological Survey, Wetland and Aquatic Research Center provides support to the BICM program through the development of habitat map products using aerial imagery and lidar elevation data and assessing change in habitats over time. These data provide a snapshot of barrier island habitats and can be combined with other past and/or future maps to monitor these valuable natural resources over time. The current effort of this habitat mapping program includes developing habitat maps for 2008 and 2015-2016 for the following BICM regions: 1) West Chenier; 2) East Chenier; 3) Acadiana Bays (only Marsh Island); 4) Early Lafourche Delta; 5) Late Lafourche Delta; 6) Modern Delta (only Chaland Headland and Shell Island); and 7) Chandeleur Islands. Additionally, a habitat change analysis will be conducted comparing reaches mapped in 2008 and 2015-2016. The BICM program has developed two habitat classification schemes which include a detailed 15-class habitat scheme and a general eight-class habitat scheme. The detailed scheme was developed specifically for this habitat mapping effort and builds off the general scheme used in previous BICM habitat mapping efforts (Fearnley and others, 2009). The additional classes developed in the detailed scheme are primarily used to further delineate various dune habitats, separate marsh and mangrove, and distinguish between beach and unvegetated barrier flat habitats. To ensure comparability between this effort and previous BICM map products, we have crosswalked the detailed classes to general habitat classes previously used by Fearnley and others (2009).

LANDFIRE 2016 Remap Existing Vegetation Cover (EVC) Micronesia

LANDFIRE's (LF) 2016 Remap (Remap) Existing Vegetation Cover (EVC) represents the vertically projected percent cover of the live canopy for a 30m cell. EVC is produced separately for tree, shrub, and herbaceous lifeforms. Training data depicting percentages of canopy cover are obtained from plot-level ground-based visual assessments and lidar observations. These are combined with Landsat imagery (from multiple seasons), topographic, climate, and other geospatial data sets to inform models built independently for each lifeform. Tree, shrub, and herbaceous lifeforms each have a potential range from 10% to 100%. The three independent lifeform datasets are merged into a single product. The EVC product is then reconciled through QA/QC measures to ensure lifeform is synchronized with both Existing Vegetation Height (EVH) and Type (EVT) products. Disturbance events not visible in the source imagery are accounted for by incorporating LF Remap Annual Disturbance products. LF uses EVC as an input for LF Remap Fuel Vegetation Cover (FVC).

Atmospheric-loading frequency response functions and groundwater levels filtered for the effects of atmospheric loading and solid Earth tides for three USGS monitoring wells, southeastern Laramie County, Wyoming, 2014–2017

The data include atmospheric-loading frequency response functions (table 1) and filtered detrended and reconstructed (trends restored) groundwater levels (tables 2–4) computed for selected, parsed time series for three USGS monitoring wells [BR–1 (USGS site 410233104093203); LN–1 (USGS site 410233104093202); and FH–1 (USGS site 410233104093201)], and the associated hourly resampled water-level and barometric-pressure time-series "pieces" (tables 2–4) used to create the parsed series. Table headings are defined in the Data Dictionary. Digital filters were developed based on the computed water-level response to Earth tides and barometric pressure in all three wells, and these filters were used to compute the filtered water-level time series in tables 2, 3 and 4 for wells BR–1, LN–1, and FH–1, respectively. The content of tables (1–4) and the development of the digital filters and filtering techniques are described in the associated publication, https://doi.org/10.3133/sir20215020.

Pallid Sturgeon Spawning Habitat in the Lower Missouri River

Lack of reproduction has been hypothesized to be a factor in the decline of the pallid sturgeon (Scaphirhynchus albus) through much of its range. Spawning habitat and behavior have only recently been documented on the Lower Missouri River, which comprises over 1,300 river kilometers of undammed river. This data consists of present habitat measurements for ten pallid sturgeon spawning events from 2008-2013 that occurred in discrete reaches dispersed over hundreds of kilometers on the Lower Missouri River.
