Data for Estimating detection and occupancy of secretive marsh bird species in low and high saline marshes in southwestern Louisiana using automated recording units Data for Estimating detection and occupancy of secretive marsh bird species in low and high saline marshes in southwestern Louisiana using automated recording units
This dataset compiles all data used in a study on occupancy of secretive marsh birds collected from automated audio recording units in southwest Louisiana. The main data files consist of detection histories for the 11 species across 20 sampling occasions at 33 sites. The sites were randomly selected, and all site level information is provided, including coordinates, marsh type, and...
Daily-timestep and monthly-timestep estimates of baseflow at 49 reference stream gages located within 25 miles of the Delaware River basin watershed boundary for the years 1950 through 2015 Daily-timestep and monthly-timestep estimates of baseflow at 49 reference stream gages located within 25 miles of the Delaware River basin watershed boundary for the years 1950 through 2015
This USGS data release contains daily-timestep and monthly-timestep estimates of baseflow at 49 reference stream gages located within 25 miles of the Delaware River basin watershed boundary. Estimates are provided for the available period of record of streamflow data at each site between 1950 and 2015. A two-parameter recursive digital filter was used to estimate baseflow at the selected...
Rangeland Ecosystem Data, Grand Canyon - Parashant National Monument, AZ, USA Rangeland Ecosystem Data, Grand Canyon - Parashant National Monument, AZ, USA
These data were compiled for an assessment of rangeland ecosystem conditions of the Grand Canyon - Parashant National Monument. The approximately one-million-acre Grand Canyon-Parashant National Monument (PARA) is located in the northwest corner of Arizona and co-managed by the Bureau of Land Management (BLM) and National Park Service (NPS). This report is focused on the ca. 200,000...
Channel Mapping of the Colorado River in Grand Canyon National Park, Arizona, May 2012, river miles 29 to 62 - Data Channel Mapping of the Colorado River in Grand Canyon National Park, Arizona, May 2012, river miles 29 to 62 - Data
Bathymetric, topographic, and grain-size data were collected in May 2012 along a 33-mi reach of the Colorado River in Grand Canyon National Park, Arizona. The study reach is located from river miles 29 to 62 at the confluence of the Colorado and Little Colorado Rivers. Channel bathymetry was mapped using multibeam and singlebeam echosounders, subaerial topography was mapped using ground...
Discrete water-quality data for the Kansas River and tributaries, July 2012 - September 2016 Discrete water-quality data for the Kansas River and tributaries, July 2012 - September 2016
This U.S. Geological Survey (USGS) Data Release provides discrete water-quality data collected from four sites on the Kansas River and four of its tributaries during July 2012 through September 2016. The water-quality constituents included in this data release are the cyanotoxins microcystin and cylindrospermopsin, the taste-and-odor compounds geosmin and 2-methylisoborneol, major ions...
Peak-flow frequency analyses for 99 selected streamgages in or near Montana, based on data through water year 2015 (ver. 1.1, August 2020) Peak-flow frequency analyses for 99 selected streamgages in or near Montana, based on data through water year 2015 (ver. 1.1, August 2020)
The USGS Wyoming-Montana Water Science Center (WYMT WSC) recently completed a report documenting methods for peak-flow frequency analysis following implementation of the Bulletin 17C guidelines. The methods are used to provide estimates of peak-flow quantiles for 50-, 42.9-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probabilities (AEPs) for selected streamgages...
