Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Data for experimental conservation translocations of an aquatic invertebrate (Gammarus lacustris) in Minnesota USA from years 2017-2020 Data for experimental conservation translocations of an aquatic invertebrate (Gammarus lacustris) in Minnesota USA from years 2017-2020
The dataset accompanies the scientific article, "Experimental conservation translocations of an aquatic invertebrate (Gammarus lacustris) within prairie and forest-transitional wetlands". In this study, we conducted a before-after/control-impact experiment to test the efficacy of conservation translocation for re-establishing abundant populations of the freshwater amphipod Gammarus...
Digital 3D database of faulted horizons in the northern Arkoma basin, Arkansas Digital 3D database of faulted horizons in the northern Arkoma basin, Arkansas
This is a digital dataset to accompany the journal article "Influence of inherited structure on flexural extension in foreland basin systems: Evidence from the northern Arkoma basin and southern Ozark dome, USA", published in April 2024 by Earth Science Reviews. This dataset contains point features, line features, and raster grids that together constitute a 3D structural model of the...
Digital elevation model of the lava dome in the crater of Mount St. Helens, June 23, 1982 Digital elevation model of the lava dome in the crater of Mount St. Helens, June 23, 1982
The catastrophic, explosive eruption of Mount St. Helens, Washington, on May 18, 1980, is the most well-known eruption of the volcano. Less well known is the May 18 eruption marked the beginning of a period of eruptive activity that lasted through 1986. Beginning in October 1980, a series of 17 dome-building episodes added millions of cubic meters of lava to the crater floor. Most of the...
Corresponding dataset for effectiveness of canine-assisted surveillance and human searches for early detection of invasive spotted lanternfly Corresponding dataset for effectiveness of canine-assisted surveillance and human searches for early detection of invasive spotted lanternfly
This study experimentally tested whether utilizing trained detector dogs could improve the probability of detecting SLF in both agricultural and forest settings. This dataset includes the data from spotted lanternflys (SLF) surveys in 20 vineyards in Pennsylvania and New Jersey, USA using both human and trained detection dogs as observers. We used a multi-scale occupancy model to...
MODFLOW6 Groundwater Flow Model, MODPATH Particle-Tracking Simulation, and Groundwater-Transported Nitrogen Load Model of Average Monthly Conditions in Coastal Connecticut and Adjacent Areas of New York and Rhode Island, 1993 - 2022 MODFLOW6 Groundwater Flow Model, MODPATH Particle-Tracking Simulation, and Groundwater-Transported Nitrogen Load Model of Average Monthly Conditions in Coastal Connecticut and Adjacent Areas of New York and Rhode Island, 1993 - 2022
A groundwater flow model simulating average monthly conditions, using MODFLOW6, was developed to better understand groundwater flow and groundwater-transported nitrogen loads in coastal Connecticut and adjacent areas of New York and Rhode Island. Elevated nitrogen loads are a pervasive issue in the Long Island Sound, an estuary that receives freshwater and nutrients from both surface...
Summary Simulated Groundwater-transported Nitrogen Loads on the North Shore of Long Island Sound and Associated Data Summary Simulated Groundwater-transported Nitrogen Loads on the North Shore of Long Island Sound and Associated Data
A monthly model of groundwater-transported nitrogen loads was developed for 12-digit hydrologic unit code (HUC12) watersheds on the north shore of Long Island Sound in coastal Connecticut and adjacent areas of New York and Rhode Island. As part of the analysis, potential management actions that upgraded septic systems or reduced fertilizer application to areas of turf-grass were also...
