To better understand pesticide exposure, silicone band samples were placed in five National Wildlife Refuges in the Sacramento Valley of Northern California. Silicone bands, used as aerial passive sampling collection devices, were flag-pinned half a meter off the ground and deployed for 28 days in the spring of 2023 (total of 176 bands). Upon retrieval, silicone bands were extracted via sonication

To advance the USGS 3D National Topography Model (3DNTM) including the next generation of the 3D Elevation Program (3DEP) and the 3D Hydrography Program, USGS is producing a new one-meter resolution seamless digital elevation model (DEM) product. The project is funded by the Inflation Reduction Act. This dataset is a 1-m seamless DEM prototype that was created from several different 3D Elevation P

This dataset provides topographic indices derived from 1 m resolution DEMs for sequoia groves in both Sequoia-Kings Canyon and Yosemite National Parks. All mapped sequoia groves in Sequoia-Kings Canyon National Park and two groves from Yosemite National Park, Merced and Mariposa, are included. For each grove, aspect, slope, the stream network, height above nearest drainage (HAND), depth to water (

This dataset includes elevation-based probability and depth statistics for estimating inundation under various sea-level rise and high tide flooding scenarios in and around the National Park Service’s San Juan National Historic Site. These datasets were developed using 1-m digital elevation model (DEM) from the 3D Elevation program. This data release includes results from analyses of two local sea

The U.S. National Seismic Hazard Model (NSHM) for the state of Alaska was updated in 2023 as part of the 50-state NSHM update. The new model incorporates more than 15 years of additional science since the release of the previous model in 2007 and has been reviewed by a six-member review panel and a supplementary eight-member team of ground motion model developers. This time-independent probabilis

This dataset contains tables of estimated fertilizer and manure nutrient inputs in kilograms to individual stream catchments of the continental United States from the National Hydrography Dataset Plus Version 2.1 (McKay and others, 2012). These data were downscaled from county-level estimates of nitrogen and phosphorus inputs from Falcone (2021) by allocating mass of applied nutrients to appropria

Tungsten is a mineral commodity critical for national security and the economy. Vein and greisen deposits host wolframite, a tungsten ore mineral that accounts for a significant portion of global mine production and resources. This data release contains updated resource information for globally distributed deposits that underpin grade and tonnage modeling efforts.

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 lacustris in ye

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 growth oc

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 estimate detectio

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-water and gr

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 simulated. T
