Thickness of the Chicot aquifer system of southwestern Louisiana's surficial confining unit and shallow sand lenses Thickness of the Chicot aquifer system of southwestern Louisiana's surficial confining unit and shallow sand lenses
The Chicot aquifer system is a vital water resource for Southwestern Louisiana, providing nearly half of the fresh groundwater the region consumes (Sargent, 2011). The aquifer’s surficial confining unit consists of a wedge-shaped thickening sequence of south to southeastern dipping, interbedded clays and coarser material (primarily sand and gravel). In collaboration with the Louisiana...
HASP HASP
The Hydrologic Analysis Package (HASP) can retrieve groundwater level and groundwater quality data, aggregate these data, plot them, and generate basic statistics. One of the benefits of HASP is its ability to aggregate two time-series of data into one record and generate statistics and graphics on hat record. By merging two data sets together, users can view and manipulate a much longer...
Preliminary model data for lake level gate operation and discharge at Reelfoot Lake - Tennessee and Kentucky Preliminary model data for lake level gate operation and discharge at Reelfoot Lake - Tennessee and Kentucky
Reelfoot Lake, in northwestern Tennessee and southwestern Kentucky, is home to a Federal wildlife refuge, a State wildlife-management area, and to a tourism industry that is based on hunting, fishing, birding, and the area’s unique cultural history. In 2012, the U.S. Geological Survey, in cooperation with the Tennessee Wildlife Resources Agency, began a series of hydrologic...
Coastal Bathymetry and Backscatter Data Collected in June 2021 from Rockaway Peninsula, New York Coastal Bathymetry and Backscatter Data Collected in June 2021 from Rockaway Peninsula, New York
Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS-SPCSMC), conducted a geophysical survey nearshore the Rockaway Peninsula, New York, during June 2021. During this study, multibeam bathymetry and acoustic backscatter data were collected aboard the R/V Sallenger. Efforts were supported by the National Fish and...
Datasets for Rapid Assessment of Streambank Erosion Potential for Selected Streams throughout the Greater Raleigh Area, North Carolina, 2022 Datasets for Rapid Assessment of Streambank Erosion Potential for Selected Streams throughout the Greater Raleigh Area, North Carolina, 2022
As part of a collaborative study with the City of Raleigh, North Carolina, the U.S. Geological Survey is assessing streambank erosion potential in selected stream reaches throughout the Greater Raleigh metropolitan area. Rapid field measurement techniques were used to assess streambank stability at 124 stream segments between January and March 2022. Field data were collected using the...
Keys Carbonate Budget Calculations and Analysis Keys Carbonate Budget Calculations and Analysis
The code 'Keys Carbonate Budget Calculations', written in R (v.4.0.4; https://www.R-project.org/), uses benthic coral-reef survey data and fish survey data to calculate coral-reef carbonate budgets following the ReefBudget v2 methodology (http://geography.exeter.ac.uk/reefbudget/; Perry and Lange, 2019). The carbonate budgets include estimates (means +/- standard errors) of gross...
