Soil characteristics and microbial taxonomy in selected urban stormwater best management practices (BMPs) in Clarksburg, MD, 2015 Soil characteristics and microbial taxonomy in selected urban stormwater best management practices (BMPs) in Clarksburg, MD, 2015
The data were gathered as a preliminary assessment of soil microbiology and conditions in selected urban stormwater best management practices (BMPs) in Clarksburg, MD. Four bioretention facilities (BF), four dry ponds (DP), and four surface sand filters (SSF) were selected. Three samples were taken from each BMP (a single sample from one dry swale (DS) was also collected). BMPs were...
Structure-from-motion datasets of Fall Creek Lake, Oregon, acquired during annual drawdown to streambed November 2016 Structure-from-motion datasets of Fall Creek Lake, Oregon, acquired during annual drawdown to streambed November 2016
The Middle Fork Willamette River basin encompasses 3,548 square kilometers of western Oregon and drains to the mainstem Willamette River. Fall Creek basin encompasses 653 square kilometers and drains to the Middle Fork Willamette River. In cooperation with the U.S. Army Corps of Engineers, the U.S. Geological Survey evaluated geomorphic responses of downstream river corridors to annual...
Target-Chemical Concentrations in Landfill Leachate and Wastewater Treatment Influent and Effluent Target-Chemical Concentrations in Landfill Leachate and Wastewater Treatment Influent and Effluent
Concentration results and quality assurance for pharmaceutical, hormone, and per- and polyfluorinated alkyl substances (PFAS) analyzed in landfill leachate and wastewater influent and effluent. Samples were collected between July and October 2016, using U.S. Geological Survey field methods. Water-quality samples for pharmaceutical and hormone compounds (reported in nanograms per liter...
Hawaii Island forest bird response to simulated nest predator 2015-2016 Hawaii Island forest bird response to simulated nest predator 2015-2016
Hawaii forest birds nesting in Hakalau Forest National Wildlife Refuge were exposed to models of predators near their nests to measure behavioral responses. Responses to potential nest predators included vocalization rate, movement behavior, and nestling feeding. Predators were inert stick, introduced but abundant predator, a rat, and a novel predator, a snake, that does not occur on...
Database for the geologic map of the Paeroa Fault block and surrounding area, Taupo Volcanic Zone, New Zealand Database for the geologic map of the Paeroa Fault block and surrounding area, Taupo Volcanic Zone, New Zealand
The Taupo Volcanic Zone (TVZ), New Zealand, is the most productive area of explosive silicic volcanism in the world. Faulted early and middle Pleistocene volcanic products are generally concealed beneath voluminous, generally unfaulted, younger volcanic products. An exception is the southeast margin of the TVZ where the two parallel, northeast-trending Paeroa and Te Weta Fault blocks...
Environmental data collected at piezometer field plot locations used to study hydrologic impacts on vegetation due to historic rail road embankment at Canaan Valley NWR Environmental data collected at piezometer field plot locations used to study hydrologic impacts on vegetation due to historic rail road embankment at Canaan Valley NWR
This data represents environmental attributes collected at or around field sample locations (groundwater piezometers or water wells) that were used in a study of impacts from a historic railroad embankment on wetland vegetation. GPS surveys were used to map piezometer locations, elevations, and the elevation of the ground surface in proximity to the piezometer. Water surface elevations...
