Data Release: Peat collapse and vegetation shift after storm-driven saltwater surge in a tidal freshwater swamp, roots

Annual root production over time was measured by collecting data on ingrowth into mesh root bags. The study was conducted on tidal freshwater swamp environments subjected to salinity intrusion at Hickory Point State Forest near Pocomoke City, Maryland. Root bags were collected at 5 set locations within the study area from 2013 to 2021 and analyzed to determine the weight in grams of new root production per meter cubed each year.

2013-2014 Northeast USGS Lidar-Derived Dune Crest, Toe and Shoreline

The Storm-Induced Coastal Change Hazards component of the National Assessment of Coastal Change Hazards project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. Lidar-derived beach morphologic features such as dune crest, toe and shoreline help define the vulnerability of the beach to storm impacts. This dataset defines the elevation and position of the seaward-most dune crest and toe and the mean high water shoreline derived from the 2013-2014 Post\x96Hurricane Sandy Northeast (New York to New Hampshire) USGS lidar survey. Beach width is included and is defined as the distance between the dune toe and shoreline along a cross-shore profile. The beach slope is calculated using this beach width and the elevation of the shoreline and dune toe.

One-second USGS College (CMO) magnetic observatory data collected before 2013

The USGS Geomagnetism Program operates a network of magnetic observatories that collect vector and scalar magnetometer data for use in Earth main-field modeling, geophysics research, space physics research, and space weather hazard assessment and mitigation. Until mid-2011, only 1-minute time resolution magnetic field measurements were archived with the INTERMAGNET consortium following international magnetic observatory standards. 1-second time resolution magnetic field measurements, which had already been collected by all the USGS observatories for up to almost a decade prior, started being archived with INTERMAGNET on June 13, 2011, or July 27, 2012 in the case of the more recently constructed Deadhorse (DED) magnetic observatory. This data release contains 1-second time resolution magnetic field measurements collected up through the end of 2012, after which time 1-second data from USGS magnetic observatories may be obtained from INTERMAGNET. There is some overlap between data in this release and those data archived with INTERMAGNET. Any discrepancies that may exist between these two data sources should resolve in favor of INTERMAGNET.
CMO-specific notes:
- there are significant gaps in the 2004 data, most notably in April
- some filenames originally and mistakenly identified the College observatory as "COL", not "CMO".
- some filenames originally possessing with a ".sec" extension were renamed to ".raw"

Estimated public-supply water withdrawals and domestic water use in Puerto Rico (ver. 2.0, March 2023)

The U.S. Geological Survey estimates annual public-supply water withdrawn from freshwater sources in Puerto Rico using data obtained from various agencies on the island, including the Puerto Rico Aqueduct and Sewer Authority (PRASA), and the Puerto Rico Department of Health (PRDOH). Public-supply withdrawals from surface and groundwater sources are tabulated by municipality, and by PRASA water service area or public water supply system. 
When supporting information is available, the USGS also tabulates annual domestic water use for users supplied by public systems such as PRASA and non-PRASA community water systems which are certified by PRDOH. Domestic water use includes indoor and outdoor uses at residences. 
Version 2.0
Estimated public-supply water withdrawals in Puerto Rico for the years 2017–20 have been published. This data release consists of Microsoft Excel workbooks related to a cooperative project between the U.S. Geological Survey (USGS) and the Puerto Rico Aqueduct and Sewer Authority (PRASA) to estimate public-supply water withdrawals for the years 2017–20. The total annual volume withdrawn from PRASA and non-PRASA public-supply wells and surface-water intakes was aggregated by municipality and PRASA public water system identification (PWSID) to obtain total surface-water and groundwater withdrawals for PRASA and non-PRASA systems. 
Changes from previous version:
Estimated public-supply water withdrawals in Puerto Rico for the years 2017–20 have been added as child pages to the project page in ScienceBase.
Additional co-authors for the years 2017-20 added to the project page citation: Irizarry-Ortiz, M., Santiago, M., Pazmino-Hernandez, M., and Kahlid, S.

Landscape and connectivity metrics based on invasive annual grass cover from 2016-2018 summarized at 15 kilometer grid cells in the Great Basin, USA

The spatial context of invasions is increasingly recognized as important for the success and efficiency of management actions. This information can be key for managing invasive grasses that threaten native ecosystems. We calculated landscape metrics and circuit-based centrality for invasive grasses using a source input raster of weighted-average annual herbaceous cover from 2016-2018 (Maestas et al. 2020, 30 meter resolution) in the Great Basin, USA. 
This shapefile data product includes the summarized landscape metrics and connectivity metrics for 15 kilometer grid cells (n = 2408) across the Great Basin, USA. Metrics for each grid cell include: mean patch area (area_mn), class area (ca), number of patches (np), largest patch index (lpi), mean Euclidean nearest neighbor distance (enn_mn), mean patch contiguity (cntg_mn), aggregation index (ai), and centrality (cntrlty). We also calculated dominant abundance class (dm_bnd_) for comparison with these metric values.

Baseline High Resolution Land Cover Map for the Mainstem Klamath River Corridor Downstream of Iron Gate Dam, Klamath River, CA, 2018

This data release includes a file geodatabase with land cover maps for a 313-kilometer segment along the mainstem Klamath River corridor downstream from Iron Gate Dam, CA. The maps were derived from high-resolution (15cm) imagery and topobathymetric elevation data, collected by NV5 Geospatial (formerly QSI, Inc) and published on Open Topography (https://doi.org/10.5069/G9DN436N). Acquisition dates spanned 06/01/2018 to 06/14/2018. The area of interest was discretized into three zones and land cover maps were generated using geoprocessing tools, implemented in ArcMap 10.8.1, and image classification tools, implemented in Ecognition 10.2. The maps include six land cover classes: 1) trees, 2) shrubs, 3) grass, 4) bare ground, 5) rock outcrop and 6) water. Water was defined by a lidar hydrobreak raster product. Trees, shrubs and grass were classified using a lidar-derived canopy height model and threshold values in vegetation indices. The bare ground and rock outcrop classes were further classified using a random forest classifier. A total of 639 independent reference points were used in an accuracy assessment. The overall accuracy of the Level II classification (all 6 classes) is 87%. The overall accuracy of the Level I classification [ 6) water, 7) vegetation (trees, shrubs, grass) and 8) unvegetated (bare ground, rock outcrop) ] is 95.1%. See attached Klamath_AccuracyAssessment.csv for more details. The file geodatabase includes land cover maps for three zones. Zone A covers Iron Gate Dam to Fort Goff. Zone B covers Fort Goff to Somes Bar. Zone C covers Somes Bar to the estuary. The USGS Integrated Water Availability Assessments (IWAAs) Program and the USGS National Land Imaging Program funded generation of these high-resolution digital products.

Point Cloud derived from historical aerial imagery of the South Cow Mountain Recreational Area, Lake County, California, 19770527

The USGS, in cooperation with the U.S. Bureau of Land Management (BLM), created a series of geospatial products using historic aerial imagery and Structure from Motion (SfM) photogrammetry methods.  A point cloud dataset (.laz) of the South Cow Mountain Recreational Area was generated from stereo historical aerial imagery acquired in by the BLM in 1977. The aerial imagery was downloaded from the USGS Earth Resources Observation and Science (EROS) Data Center's USGS Single Aerial Frame Photo archive and the point cloud was created using USGS guidelines. 
Photo alignment, error reduction, and dense point cloud generation followed guidelines documented in Over, J.R., Ritchie, A.C., Kranenburg, C.J., Brown, J.A., Buscombe, D., Noble, T., Sherwood, C.R., Warrick, J.A., and Wernette, P.A., 2021, Processing coastal imagery with Agisoft Metashape Professional Edition, version 1.6— Structure from motion workflow documentation: U.S. Geological Survey Open-File Report 2021–1039, 46 p., https://doi.org/10.3133/ofr20211039. 
Photo-identifiable points, selected as synthetic ground-control points, followed guidelines documented in Sherwood, C.R.; Warrick, J.A.; Hill, A.D.; Ritchie, A.C.; Andrews, B.D., and Plant, N.G., 2018. Rapid, remote assessment of Hurricane Matthew impacts using four-dimensional structure-from-motion photogrammetry https://doi.org/10.2112/JCOASTRES-D-18-00016.1
Additional post-processing of the 1977 dense point cloud, using Iterative Closest Point (ICP) analysis, was used to improve the alignment with the 2015 LiDAR point cloud. The ICP analysis is explained in Low, K.L., 2004. Linear least-squares optimization for point-to-plane ICP surface registration. Chapel Hill, University of North Carolina, 4(10), pp.1-3. http://www.comp.nus.edu.sg/~lowkl/publications/lowk_point-to-plane_icp_techrep.pdf 
Data were processed using photogrammetry to generate a three-dimensional point cloud that identifies pixels of an object from multiple images taken from various angles and calculates the x, y, and z coordinates of that object/pixel. The point cloud was processed to create a digital surface model of the study area (57.3 cm resolution). Finally, source images were stitched together based on shared pixels and orthogonally adjusted to the digital surface model to create a high resolution (approximately  18.3 cm) orthoimage for the study area.

PIT Tags Encountered by Klamath Falls Field Station Equipment in the Upper Klamath Basin

Data were collected as part of a long-term capture-recapture program to assess the status and dynamics of populations of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon and Clear Lake Reservoir, California. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated transponder (PIT) tags during their spawning migrations in each year since 1995.PIT tagged species were encountered in netting efforts, remote transceivers, and active scanning on bird colonies across the Upper Klamath River Basin (predominately Upper Klamath Lake and Clear Lake Reservoir). The data includes detections for endangered suckers, but also salmonids and other PIT tagged aquatic species that were encountered.

Total mercury, methylmercury, and isotopic composition in various life stages of boreal chorus frogs (Pseudacris maculata) at two subalpine ponds in the Rocky Mountains, CO, USA, 2015

Mercury is an atmospherically transported contaminant found even in relatively pristine habitats. Once accumulated at the base of the food web, mercury can move between animals that are linked trophically. Pond-breeding amphibians may be particularly important vectors of mercury flux from remote freshwater to terrestrial systems because they feed on algae and detritus as tadpoles and metamorphose into insectivorous terrestrial adults where they carry out most of their remaining life cycle. However, it is still unclear how mercury concentrations change across life stages in complex life cycle amphibian species. The data presented here includes total mercury (THg), methylmercury (MeHg), and isotopic composition (δ13C, δ15N) in boreal chorus frogs (Pseudacris maculata) at two subalpine ponds in the Rocky Mountains, CO, USA. We sampled various life stages including breeding adults, eggs, tadpoles, metamorphs, and mid-summer adults.

Geospatial data to assess karst aquifer systems between Albany and Buffalo, New York (ver. 4.0, January 2024)

Using publicly available data for Onondaga and Cayuga counties, New York, a series of geospatial overlays were created at 1:24,000 scale to examine the bedrock geology, groundwater table, soils, and surficial geology. Bedrock and surficial geology were refined using extant bedrock maps, well and borehole data from water- and gas-wells, soil data, and lidar data. Groundwater data were collected from New York State Department of Environmental Conservation and U.S. Geological Survey water-well databases to estimate the groundwater table. Soil data were used to examine soil thickness over bedrock and infiltration. 
An inventory of closed depressions was created using reconditioned lidar-derived bare-earth digital elevation models (DEMs) and a modeled stream network. Closed depressions were identified from the processed DEMs using threshold criteria of 10 and 30 centimeters (3.9 and 11.8 inches) for depth and 100 square meters (1076 square feet) for area. A combination of hydrologic, mining, and cultural features was used to eliminate false positives and filter out features that overlie existing waterbodies, streams, and mines and to remove artificial dams along roadways and railways. 
This data release includes shapefiles containing the well data information including location, well depth, depth to bedrock, and groundwater depth; bedrock geology; surficial geology; interpolated bedrock surface contours; interpolated groundwater surface contours; soil saturated hydraulic conductivity; soil classes; and modeled closed depressions of 10 cm and 30 cm depth thresholds. This release also contains rasters of the interpolated bedrock surface, interpolated groundwater surface and land use.

MODFLOW-One-Water model used to support the Central Platte Natural Resources District Groundwater Management Plan

An integrated hydrologic-flow model, called the Central Platte Integrated Hydrologic Model, was constructed using the MODFLOW-One-Water Hydrologic Model code with the Newton solver. This code integrates climate, landscape, surface water, and groundwater-flow processes in a fully coupled approach.  This study provided the Central Platte Natural Resources District (CPNRD) with an advanced numerical modeling tool to assist with the update of their Groundwater Management Plan by providing them information on modeled future GW levels under different climate scenarios and management practices. This tool will allow the CPNRD to evaluate other scenarios as management changes in the future.  A predevelopment model simulated steady-state hydrologic conditions prior to April 30, 1895 and a development period model discretized into 610 stress periods simulated transient hydrologic conditions from May 1, 1895, to December 31, 2016, using 170 biannual stress periods from 1895 to 1980, and monthly stress periods from May 1, 1980 to December 31, 2016.  The calibrated Central Platte Integrated Hydrologic Model was used to simulate the effects of eight different potential future climate and irrigation pumping conditions from January 1, 2019, to December 31, 2049.  This USGS data release contains all of the input and output files for the simulations. The user should first open the readme.txt file for descriptions on how to download this model archive and what files are contained in each .7z file.
