Water Quality Data for Multidecadal Change in Pesticide Concentrations Relative to Human Health Benchmarks in the Nation’s Groundwater Water Quality Data for Multidecadal Change in Pesticide Concentrations Relative to Human Health Benchmarks in the Nation’s Groundwater
In the United States, the widespread use of pesticides has led to contamination of groundwater resources. Three decades ago, the U.S. Geological Survey (USGS) established a national water quality monitoring network for groundwater (NWQN-GW). This network provides an overview of groundwater conditions across a wide range of hydrogeologic settings and capture the impacts of pesticide use...
Data and analytical code associated with a modified Lotka-Volterra model, assessing population-level co-occurrence effects between barred (Strix varia) and northern spotted owls (Strix occidentalis caurina), in western Oregon (1990 – 2015) Data and analytical code associated with a modified Lotka-Volterra model, assessing population-level co-occurrence effects between barred (Strix varia) and northern spotted owls (Strix occidentalis caurina), in western Oregon (1990 – 2015)
This data release provides data from the 2016 Lesmeister et al. technical report and Mathematica and Python analytical code to model co-occurrence effects between barred (Strix varia) and northern spotted (Strix occidentalis caurina) owls. This data release, containing sample data set and code, is designed to facilitate reproducibility of analyses associated with the manuscript titled...
Surface Geophysical Data Collected at, and Adjacent to Hanscom Air Force Base, Bedford, Massachusetts, 2024 Surface Geophysical Data Collected at, and Adjacent to Hanscom Air Force Base, Bedford, Massachusetts, 2024
In 2024 the U.S. Geological Survey (USGS), in cooperation with the Air Force Civil Engineer Center (AFCEC), conducted geophysical surveys at Hanscom Air Force Base, Hanscom Field, and surrounding areas in Massachusetts. Methods used included frequency-domain electromagnetic induction (EMI), ground-penetrating radar (GPR), horizontal-to-vertical spectral ratio (HVSR) passive seismic...
Water Quality Vertical Profile Data in West Thompson Lake, Connecticut, 2022 and 2024 Water Quality Vertical Profile Data in West Thompson Lake, Connecticut, 2022 and 2024
This data release consists of vertical water-quality profile data collected at three locations in West Thompson Lake Connecticut from June to October 2022 and from May to October 2024. The U.S. Geological Survey, in cooperation with the Connecticut Department of Energy and Environmental Protection, collected these data to assess physical property stratification in the West Thompson Lake...
Kīpahulu Valley, Haleakalā National Park, Maui bird, mosquito, and avian malaria infection data, 2002 and 2019 Kīpahulu Valley, Haleakalā National Park, Maui bird, mosquito, and avian malaria infection data, 2002 and 2019
This data publication contains data files collected as part of a field and laboratory effort aimed at estimating the prevalence and altitudinal distribution of avian malaria in forest birds and in the primary vector of malaria in Hawaii, Culex quinquefasciatus in Kīpahulu Valley, Haleakalā National Park, on the island of Maui in 2002 and 2019. To track the spread of mosquitoes and...
