Quetrupillán Volcanic Complex, southern Chile: Argon age data and Pb, Sr, and Nd isotopic data

This dataset accompanies planned publication 'Lava-ice interactions at late Pleistocene trachyte-basaltic andesite fissure eruptions, Quetrupillán Volcanic Complex (39°30′ S, 71°43′ W), southern Chile', as well as planned future publications on this volcanic complex. The Ar/Ar data and the Pb, Sr, and Nd data are for basalt and trachyte lava flows at Quetrupillán volcano. The Ar geochronology and isotope geochemistry will aid in the understanding of the timing of eruptive activity and glacial damming of lava flows, and magma source compositions studied in the planned publications. Samples were collected from Quetrupillán volcano by Dave McGarvie (Univ. of Lancaster, UK) and Isla Simmons (Univ. of Edinburgh, UK), who sent them to the USGS Denver for analysis. The analyses were performed from March 2021 to Feb 2023.

Potential suitable habitat for Pahrump orache (Atriplex argentea var. longitrichoma) in the California desert

Here we present the map of potential suitable habitat for Pahrump orache (Atriplex argentea var. longitrichoma). The data indicate both how many models predicted each location to be potentially suitable for the species and the average standardized habitat suitability score for each location.Data are presented at a spatial resolution of 10 m pixels, which was required to harmonize the original model inputs. However, maps of suitable habitat should be used at a resolution no smaller than 360 m (i.e., 36 pixels x 36 pixels), which corresponds with the resolution of the coarsest model input. These data are intended to be used only to target future plant surveys in areas where new occurrences are most likely to benefit future habitat modelling efforts. Complete methods and other additional information are provided in the article associated with this data release (Reese and others, 2019).

Coastwide Reference Monitoring System (CRMS) 2005, 2008, 2012, 2016, 2018, and 2021 Site 3590 land-water matrix

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring to determine the efficacy of these projects. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 390 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Digital Orthophoto Quarter Quadrangles (DOQQs) approximately every three years at all CRMS sites. This dataset consists of a matrix of six land-water products (2005, 2008, 2012, 2016, 2018, and 2021).  The resulting matrix has 64 possible classes defined by the combination of land and water categories on those six dates.

An Unvegetated to Vegetated Ratio (UVVR) for coastal wetlands of the Atlantic Coast - 1999

Prior research has shown that sediment budgets, and therefore stability, of microtidal marsh complexes scale with areal unvegetated to vegetated marsh ratios (UVVR) suggesting these metrics are broadly applicable indicators of microtidal marsh vulnerability. This effort has developed the UVVR metric using readily available satellite imagery for the coastal areas of the contiguous United States (CONUS). These datasets provide annual averages of the 1) unvegetated fraction, 2) vegetated fraction, 3) water fraction and 4) an unvegetated to vegetated ratio (UVVR) at 30-meter resolution over the coastal areas of the contiguous United States for the year 1999. Additionally, multi-year average values of vegetated ratio, its standard deviation and a UVVR based on the annually-averaged vegetated ratio are provided for the coastal wetlands of the contiguous United States.

Daily and annual abundances of natural- and hatchery-origin age-0 fall Chinook salmon (Oncorhynchus tshawytscha) passing Lower Granite Dam, Washington 1992 - 2021

The main contents of this data release are estimates of daily and annual abundances of federally-threatened natural-origin age-0 fall Chinook salmon (Oncorhynchus tshawytscha) passing Lower Granite Dam, Washington. Fish from this population are sampled as they pass Lower Granite Dam, but these sample data cannot be used directly to infer abundance because capture probability at Lower Granite Dam varies throughout the migration and because of the contemporaneous presence of unmarked hatchery-origin fish which are visually indistinguishable from natural-origin fish.
Estimates of abundance were obtained by fitting a statistical mark-recapture model that integrated four related datasets: 1) the release/recapture data of passive integrated transponder juvenile salmon tagged as either part of a natural-origin fish survey or as part of hatchery monitoring efforts, 2) daily counts of fish sampled by the smolt monitoring program at Lower Granite Dam, 3) hatchery release data and 4) environmental and operational covariates of Lower Granite Dam. An integrated Bayesian mark-recapture model fit joint parameters for daily fish arrival and capture probabilities to these data to estimate the daily abundance of hatchery- and natural-origin fish. 
In addition to the main results, this data release contains the raw data used to the fit the models and related parameters such as daily capture probability estimates and daily abundances of hatchery-origin fish.

Digital Shoreline Analysis System version 4.3 Transects with Short-Term Linear Regression Rate Calculations for Mississippi

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate.  Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.
There is no widely accepted standard for analyzing shoreline change.  Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments.  The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast.  The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.

Attributes for NHDPlus Version 2.1 Catchments and Modified Routing of Upstream Watersheds for the Conterminous United States: National Land Cover Database 2001 (NLCD 2001)

This tabular data set represents the percent of land cover classes from the 2001 National Land Cover Dataset compiled for two spatial components of the NHDPlus version 2 data suite (NHDPlusv2) for the conterminous United States; 1) individual reach catchments and 2) reach catchments accumulated upstream through the river network. This dataset can be linked to the NHDPlus version 2 data suite by the unique identifier COMID.  The source data is the "National Land Cover Database 2001" produced by the United States Geological Survey (Homer and others, 2007). Units are percent. The "National Land Cover Database 2001" (NLCD 2001) is a 16-class (additional four classes in Alaska only) land cover classification scheme that has been applied consistently across all 50 United States and Puerto Rico at a spatial resolution of 30 meters. Reach catchment information characterizes data at the local scale. Reach catchments accumulated upstream through the river network characterizes cumulative upstream conditions.  Network-accumulated values are computed using two methods, 1) divergence-routed and 2) total cumulative drainage area. Both approaches use a modified routing database to navigate the NHDPlus reach network to aggregate (accumulate) the metrics derived from the reach catchment scale. (Schwarz and Wieczorek, 2018).

Data from a Circumpolar Survey on Recreational Activities in Polar Bear Habitat, 2017-2018

These data are the responses of researchers, managers, community members, and tour guides who live or work in polar bear habitats anywhere within their range to inquiries about the types, frequency, and potential impacts of recreational activities. Respondents answered a series of questions on their background and experience with polar bears and the geographic area in which they are familiar. Respondents then indicated how common specific types of recreations are in the area in which they are familiar and whether various types of potential impacts were perceived or had been observed to occur. Finally, respondents prioritized a list of management actions and research needs.

Select borehole data for Edwards Air Force Base and vicinity, Antelope Valley, CA

Edwards Air Force Base (EAFB) is located in Kern County, CA, approximately 35 kilometers (km) northeast of Lancaster and 9 km south of California City. The Air Force Research Laboratory (AFRL) is situated on EAFB, approximately 7 km southwest of Boron, CA. Release of contaminants from the AFRL facilities have contaminated local groundwater, which is mostly restricted to fractured granitic bedrock, but studies indicate that the groundwater and contaminant plumes have moved into alluvial deposits to the north and northwest (AECOM, 2014). The U.S. Geological Survey (USGS) and the Air Force Civil Engineer Center (AFCEC) entered into a cooperative agreement in 2017 to develop a hydrogeologic framework model to help determine groundwater movement and the geologic and lithologic structures that control groundwater movement. This dataset of lithologic descriptions from boreholes was used for lithologic analysis to build a hydrogeologic framework in the EAFB area. Data includes the California Department of Water Resources borehole log number (if known), state well number (if applicable), location information, and detailed lithologic descriptions, including depth to bedrock where present, for each borehole.

Data and regression models used to estimate chloride concentration and road salt loading for an urban rain garden, Gary, Indiana

This data release contains data used to develop linear regression models to calculate continuous chloride concentrations in groundwater and runoff at an urban rain garden in Gary, Indiana. A python script was developed to perform the regression analysis and estimate sodium chloride (NaCl) loading to 5 rain-garden flumes as the product of: (1) the estimated continuous (one-minute) chloride concentration, (2) the mass ratio of sodium chloride to chloride, and (3) continuous flume discharge. The python source code used to execute the regression model and loading calculations is included in this data release in the zipped folder named Model_Archive.zip. The regression input (discrete specific conductance and chloride concentration data), chloride concentration model input (continuous specific conductance data) and NaCl loading model input (continuous flume discharge and specific conductance data) that were used to estimate chloride concentrations at 3 USGS monitoring wells (413610087201001, 413612087201301, 413611087201004) and NaCl loading at 5 USGS rain garden flume monitoring stations (413611087201101, 413611087201001, 413612087200901, 413611087200901, 413611087201002) are also included as part of the model archive (Model_Archive.zip). The model output consists of 3 .csv files for the USGS monitoring wells with estimated continuous (hourly) chloride concentrations (mg/L) and 5 .csv files for the USGS flume monitoring sites with estimated continuous (1-minute) chloride concentrations (mg/L) and NaCl loading (grams) that are presented in the zipped folder Model_Output_Data.zip.

U-Pb Isotopic Data and Ages of Detrital Zircon Grains and Graptolite Fossil Data from Selected Rocks from the Western Alaska Range, Livengood area, and Seward Peninsula, Alaska

This data release contains two datasets. One dataset is of U-Pb isotopic data and associated ages of detrital zircon grains from 16 sedimentary and metasedimentary rocks from the western Alaska Range, Livengood area and Seward Peninsula, Alaska. Two samples were collected from the York Mountains area of the Seward Peninsula of western Alaska. Three samples were collected from the Livengood quadrangle of central Alaska. Eleven samples were collected from the western Alaska Range of south-central Alaska. Detrital zircon grains from each of the sixteen samples were separated and analyzed by Apatite to Zircon, Inc. (A2Z) and Geosep Services (GSS) laboratories between 2011 and 2014, using laser-ablation-inductively-coupled-plasma-mass spectrometry (LA-ICP-MS) techniques.
      The second dataset contains fossil identifications and age assignments from a select sedimentary rock from the western Alaska Range of south-central Alaska. Fossils were identified by visual inspection.
      All samples were collected as part of geological mapping research conducted between 1984 and 2014 and funded by the Mineral Resources Program of the U.S. Geological Survey.

Coastwide Reference Monitoring System (CRMS) 2016 Site 0220 land-water classification data

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring efforts to determine the efficacy of these efforts. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 390 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Digital Orthophoto Quarter Quadrangles (DOQQs) approximately every three years at all CRMS sites. A DOQQ is a raster image in which displacement in the image caused by sensor orientation and terrain relief has been removed and combines the image characteristics of a photo with geometric qualities of a map. The DOQQs generated for this project consist of 2016 Color Infrared (CIR) Digital Imagery. These images were classified into land and water categories using a threshold of the near infrared (NIR) band, followed by supervised and unsupervised classification.  Initial classification results are then reviewed by multiple image analysts to identify and manually recode errors. The final land-water classifications are intended to serve as both geographic and quantitative assessments of landscape composition on the date of acquisition. Three previous assessments have been conducted (2005, 2008, and 2012). Once the program creates enough data points for statistical analyses, these data will be used for land area change rate calculation.
