Removing threats before they spread: Eradication of two non-native fishes in Miami, Florida (USA)

Howard L. Jelks & Pamela J. Schofield
The proliferation of non-native fishes in Florida is a serious problem, and new species continue to be introduced to the State. Herein we report the eradication of two species of non-native fishes in Miami, Florida (Giant Cichlid Petenia splendida and Blue Mbuna Labeotropheus fuelleborni; both Family: Cichlidae). We removed these fishes before they were observed in the extensive, interconnected canal system through which they may have been able to expand throughout south Florida and access...

U.S. Geological Survey National Produced Waters Geochemical Database v2.3

Mark A. Engle, Varun Saraswathula, James J. Thordsen, Eric A. Morrissey, Kathleen D. Gans, Madalyn S. Blondes, Yousif K. Kharaka, Elisabeth L. Rowan & Mark E. Reidy
During hydrocarbon production, water is typically co-produced from the geologic formations producing oil and gas. Understanding the composition of these produced waters is important to help investigate the regional hydrogeology, the source of the water, the efficacy of water treatment and disposal plans, potential economic benefits of mineral commodities in the fluids, and the safety of potential sources of drinking or agricultural water. The U.S. Geological Survey National Produced Waters Geochemical Database v2.3 is an...

Data from a national survey for the amphibian chytrid fungi Batrachochytrium salamandrivorans and Batrachochytrium dendrobatidis

Brad M. Glorioso & J. Hardin Waddle
This dataset provides the results of a national survey of the conterminous U.S. for the salamander chytrid fungus Batrachochytrium salamandrivorans (Bsal) conducted by the U.S. Geological Survey Amphibian Research and Monitoring Initiative from May 2014 to August 2017. Sites were sampled by capturing amphibians by hand or by traps or nets that were then swabbed individually using methods that prevent sample contamination. All swabs were then analyzed using a real-time TaqMan PCR for detection of...

Brent T Aulenbach
This dataset contains the data and results of an analysis estimating wet deposition and streamwater solute fluxes at Panola Mountain Research Watershed (PMRW), Panola Mountain State Park, Stockbridge, Georgia for water years 1986-2016. The PMRW is a small (41 ha), relatively undisturbed, forested headwater catchment in the Piedmont Province of Southeastern United States.

A Soil-Water-Balance model and precipitation data used for HEC/HMS modelling at the Glacial Ridge National Wildlife Refuge area, northwestern Minnesota, 2002-15.

Timothy K. Cowdery & Catherine A. Christenson
A soil-water balance model (SWB) was developed to estimate evapotranspiration in six ditch basins of the Glacial Ridge National Wildlife Refuge area, northwestern Minnesota, during 2002-2015. The model was used to estimate evapotranspiration in water balances in six ditch basins as part of the associated report, U.S. Geological Survey Scientific Investigations Report 2019-5041 (http://dx.doi.org/10.3133/SIRXXXX). This SWB model was derived from the statewide Minnesota SWB potential recharge model, described, calibrated, and documented as part of U.S....

Highway-Runoff Database (HRDB) Version 1.1

Gregory E Granato
The Highway-Runoff Database (HRDB) was developed by the U.S. Geological Survey (USGS), in cooperation with the Federal Highway Administration (FHWA) Office of Project Delivery and Environmental Review to provide planning-level information for decision makers, planners, and highway engineers to assess and mitigate possible adverse effects of highway runoff on the Nation's receiving waters (Granato and Cazenas, 2009; Granato, 2013; Granato and others, 2018). The HRDB was assembled by using a Microsoft Access database application to...

Phytoplankton enumeration and identification from a recurring algal bloom location in Sullivan Bay, Kabetogama Lake, northern Minnesota, 2016

Victoria G Christensen & Hayley A Olds
This data release provides phytoplankton identification, phytoplankton enumeration, chlorophyll concentration, phaeophytin concentration, phycocyanin data, and nutrient quality assurance data from three recurring algal bloom sites in Kabetogama Lake, Voyaguers National Park, Minnesota in 2016 and 2017. The goal of this research is to better understand the drivers of algal bloom toxicity in the large lakes of Voyageurs National Park so that resource managers may better predict, manage, and mitigate the occurrence of harmful algal blooms....

Electromagnetic induction imaging (EMI) geophysical data collected at Bicycle Basin, Fort Irwin, California

Kevin Ellet, Christopher Dintaman & Jill Densmore-Judy
This data release presents raw (.csv) and processed (.csv) data files from land-based, frequency-domain electromagnetic induction (EMI) data collected at Bicycle Basin, U.S. Army Fort Irwin National Training Center, California. Data were collected during three distinct time periods: March 19, 2008 (1 survey), December 1 to December 5, 2014 (46 surveys) and December 4 to December 8, 2015 (62 surveys). Data were collected by walking along survey lines throughout the airstrip region of the basin...

EAARL-B Topography Big Thicket National Preserve: Lower Neches River Corridor Unit, Texas, 2014

Fredericks, Xan; Kranenburg, Christine J.; Nagle, David B.
These mosaics, prepared by the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center, provide lidar-derived first-surface and bare-earth topography for the Lower Neches River Corridor Unit of Big Thicket National Preserve in Texas. Elevation measurements were acquired by the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B) on January 11, 15, 17, 18, 19, 21, 23, 25, 27, and 29, 2014, in cooperation with the National Park Service Gulf Coast Network.

Raw Ground Penetrating Radar Data on North American Glaciers

Shad R O'Neel, D. McGrath, G.J. Wolken, Erin N Whorton, S.G. Candela, Louis Sass, Christopher J Mcneil, Emily H Baker, Erich H Peitzsch, Daniel B Fagre, Adam M. Clark, C.E. Florentine, Z.S. Miller, J.E. Christian, K. Christianson, E.L. Babcock, M.G. Loso, A.A. Arendt, E.W. Burgess & A. Gusmeroli
U.S. Geological Survey researchers conducted time-series ground-penetrating radar (GPR) surveys with a Sensors and Software 500-MHz Pulse Ekko Pro system. This data release contains ground-based (ski and snowmobile) as well as airborne common-offset profiles. All profiles are linked to coincident GPS observations. Additionally, common-midpoint data was collected at specific glacier locations. Coincident in-situ data may provide calibration information, and may be composed of any of the following: snow pits and/or snow-pit/snow-core combinations, probe profiles, and...

Lidar-derived Data Layers for South Carolina StreamStats, 2007-2013

Elizabeth N. Heal & Jimmy M. Clark
In cooperation with the South Carolina Department of Transportation, the U.S. Geological Survey developed a StreamStats web application (https://water.usgs.gov/osw/streamstats/) that provides analytical tools useful for water-resources planning and management (Ries and others, 2017). This data set presents the lidar-derived flow direction, flow accumulation, streamline, and hydro-enforced digital elevation model raster data used for analysis in StreamStats. Rasters are included for each of the following hydrologic unit codes (HUCs): 03040101, 03040102, 03040103, 03040104, 03040105, 03040201, 03040202,...

Hurricane Harvey: A Damage Assessment of Texas' Central Gulf Coast

The damage scale ranges from 1 (undamaged) to 5 (total structure collapse, destroyed). A score of 1 was given to structures that had no damage, a score of 2 was given to structures with minor damage, a score of 3 was given to structures with moderate damage, a score of 4 was given...

Cover of Woody and Herbaceous Functional Groups in Burned and Unburned Plots, Mojave Desert, 2009-2013

Robert C. Klinger
Arid ecosystems are often vulnerable to transformation to invasive-dominated states following fire, but data on persistence of these states are sparse. The grass/fire cycle is a feedback process between invasive annual grasses and fire frequency that often leads to the formation of alternative vegetation states dominated by the invasive grasses. However, other components of fire regimes, such as burn severity, also have the potential to produce long-term vegetation transformations. Our goal was to evaluate the...
