Data

The U.S. Geological Survey collected groundwater samples from 33 wells used for domestic and small system drinking water supplies in Santa Clara and San Benito Counties, California in 2022. The wells were sampled for the Gilroy Hollister basin and surrounding areas Domestic-Supply Aquifer Study Unit of the State Water Resources Control Board Groundwater Ambient Monitoring and Assessment...

This data release documents time-series analyses of aqueous-chemistry data from public-supply wells (PSWs) and associated potential explanatory factors to characterize responses of groundwater quality to drought and recovery periods in California’s San Joaquin Valley (SJV) during 2000-2022. Annual median nitrate values were computed for PSWs throughout the SJV during the period of study...

This data set contains toxicity data from 28- and 84-day sediment bioassays to assess the effects of contaminated Kanawha River, West Virginia sediment on juvenile mussels (fatmucket, Lampsilis siliquoidea) and one commonly tested benthic invertebrate (amphipod, Hyalella azteca) following ASTM standard methods for conducting 4-week sediment toxicity tests with the mussel and amphipod. In...

This data was collected as part of a larger project to examine predator-prey interactions between invasive Brown Treesnakes (Boiga irregularis, predator) and native prey species at a study site located in a peri-urban area of Andersen Air Force base in Guam, USA. This dataset includes two datasets. One dataset contains 22 columns and includes data collected on Brown Treesnakes captured...

The yǻyaguak (Mariana swiftlet; Aerodramus bartschi) is an endangered cave-nesting species historically found on Guam and the southern Mariana Islands, Micronesia. The population on Guam has been severely impacted by the introduction of the brown treesnake (Boiga irregularis). Population status assessments have, however, been challenging due to the limitations of traditional counting...

These data were collected as part of several studies or efforts to remove brown treesnakes (Boiga irregularis) across three sites located in Guam, USA and one site in Cocos Island (Dano), Guam, USA. The various goals of projects were distinct and these data were applied to a more intensive, cross site comparison on the height snakes were detected during visual surveys as a function of...

The Yǻyaguak (Mariana Swiftlet; Aerodramus bartschi) is an endangered cave-roosting species native to Guam and southern Mariana Islands, Micronesia. On May 24-25, 2023, Guam was hit by the category-4 Typhoon Mawar, which brought wide-spread destruction to the island. Approximately 6 weeks prior to the typhoon in April 2023 we conducted surveys of the three known colonies of Yǻyaguak at...

These data represent brown treesnake (Boiga irregularis) captures from a population in a 5 ha natural snake enclosure on Guam from 2016 - 2023. During the period of study we artificially reduced the number of snakes present in the population through a variety of control tools that included toxic baits, as mice and chicks, live trapping, and hand capture. We censused the population...

Highly altered agricultural watersheds like the Mississippi Alluvial Plain (MAP) in Mississippi, USA pose significant challenges for developing biological stressor-response relationships to monitor ecological improvements from best management practices (BMPs). Previous research (Taylor et al., 2023) has indicated that MAP streams have elevated nutrient and ion concentrations as well as...

We created a comprehensive estimate of potential distribution for a subset of 17 ecosystem modifying invasive plants (EMIPs) in Hawaiʻi. This work uses methods that integrate a wide set of data sources including agency and citizen science data, but perhaps more importantly, the integration of regional and global distribution information for these species. We built three sets of ensemble...

Catalog datasets in support of publication, "A Decade of Precursory Seismicity at Mauna Loa: 2013-2022". The earthquake catalogs begin April 1, 2009 and extend to January 1, 2023. The entire dataset has been generated with the ANSS Quake Management System (AQMS), which has the real-time software package Earthworm at its core. Automated and reviewed locations use the Hypoinverse location...

In support of a preliminary analysis performed by New York State Department of Environmental Conservation (NYSDEC) that found elevated nutrient levels along selected reaches of the Mohawk River, one-dimensional, unsteady, hydraulic and water-quality models using HEC-RAS and HEC-RAS Nutrient Simulation Module I (version 5.0.3) were developed by the U.S. Geological Survey (USGS) for the...
