Data

This dataset consists of one table containing whole-rock geochemistry data for 250 igneous and metamorphic rocks from the Darby Mountains area on the Seward Peninsula in western Alaska, collected in 2017. All materials were analyzed by ALS Global, between 2019 and 2020, by a range of different techniques; multiple unique entries for a given element relate to different analytical methods...

This data release presents whole rock geochemical data and powder X-ray diffraction (XRD) mineralogic data from a suite of mafic and ultramafic geologic units in the United States. One-hundred-twelve samples were analyzed from core and outcrop settings at thirty sites, including from the contiguous United States, Alaska, and Hawaii. Sample localities include some of the large mafic and...

A total of 1796 tree seedlings comprised of 11 species (eight families) native to the region were selected to research the possible influence of plant traits and weeding maintenance on seedling survival. The data set includes five years of plant measurements and survival data (fate) for 1796 individual seedlings planted throughout 22 plots in 4 stands with 50% of the plots receiving...

We assessed leaf and root morphological traits of seven species commonly used in restoration across the southwestern United States. Plants were grown in greenhouse conditions for four weeks followed by three weeks of growth under the following treatment conditions: control (adequate watering), moderate drought (12% soil volumetric water content), and severe drought (no water). Functional...

This model archive contains the model files for the Mobile Bay groundwater-flow model documented in the U.S. Geological Survey Scientific Investigations Report 2026–5125. The Mobile Bay model simulates transient groundwater flow in Mobile Bay and surrounding coastal areas of Alabama and Mississippi from 2008 through 2015. The primary goal of the model was to determine how changes in...

This data release contains geospatial data compiled from an investigation into the hydrology of Moreau Lake, in Moreau Lake State Park, Town of Moreau, Saratoga County, New York (Heisig, 2026). This compilation included well logs, seismic measurements, and measurements of water levels in the area to define the hydrogeologic framework and groundwater flow system around the lake...

This data release contains hydrologic and water quality data collected as part of an investigation into the hydrology of Moreau Lake, in Moreau Lake State Park, Town of Moreau, Saratoga County, New York (Heisig, 2026). These data include: 1) discrete and 2) continuous comparison measurements of lake-water levels adjacent groundwater levels at well SA1305, 3) measurements of groundwater...

The U.S. Geological Survey collected low-altitude airborne natural color imagery via a fixed-wing uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 6-mile reach of the Middle Green River at Ouray National Wildlife Refuge near Ouray, Utah. Visual imagery was collected in jpg format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over...

This data release contains data collected during campaign Global Navigation Satellite Systems (GNSS; formerly only the Global Positioning System or GPS) surveys conducted at Mount St. Helens. A survey in any given year may contain data from a subset of established sites depending on access, personnel, and the condition of the GNSS monument. For each site, we include raw data in binary or...

This data release contains Horizontal-to-Vertical Spectral Ratio (HVSR) data collected between 2017 and 2020 from 73 locations in the area surrounding Moreau Lake, Saratoga County, New York. The HVSR technique, commonly referred to as the passive-seismic method, is used to estimate the thickness of unconsolidated sediments and the depth to bedrock (Lane and others, 2008; Fairchild and...

This U.S. Geological Survey (USGS) data release contains Darcy flux and mass flux of per- and polyfluoroalkyl substances (PFAS) data measured using passive flux meters (PFMs) in monitoring wells at the Yakima Training Center (YTC) in Yakima, Washington. The measurements were conducted by the USGS in cooperation with the U.S. Army Environmental Command. This data release contains PFM data...

This data release contains coastal wetland synthesis products for the New Hampshire salt marshes. Metrics for resiliency, including the unvegetated to vegetated ratio (UVVR), marsh elevation, tidal range, and lifespan are calculated for smaller units delineated from a digital elevation model, providing the spatial variability of physical factors that influence wetland health. The U.S...
