Airborne magnetic and radiometric survey of the Wet Mountains and surrounding region, Custer and Fremont Counties, south-central Colorado, 2021

This data release provides digital flight-line and gridded data for a high-resolution airborne magnetic and radiometric survey over the region surrounding the Wet Mountains of southern Colorado, including parts of Custer and Fremont Counties. Data for this survey were collected by Sander Geophysics Limited International (SGL) under contract with the USGS.  The survey was flown in June and July of 2021 using a helicopter equipped with a magnetometer mounted in a stinger extending from the nose of the aircraft and a gamma-ray spectrometer stowed onboard.  The helicopter pilots followed pre-planned flight paths in a grid-like pattern, with east-west lines spaced 150 meters apart and north-south lines spaced 1,000 meters apart.  A terrain clearance of 80 meters above ground could be realized in areas of low relief to maximize detection of gamma-rays, but higher clearances, as much as 200-500 meters, were required over rugged terrain and populated areas for safety reasons.  A total of 17,032 kilometers were flown along the lines, covering a 2,200 square-kilometer irregular area.  SGL performed extensive data processing after completion of flying and delivered the final data and report in February 2022.

Evaluation of avoidance behavior of tadpole madtoms (Noturus gyrinus) as a surrogate to the endangered northern madtom (Noturus stigmosus) in response to granular Bayluscide®

The objective of this study was to document the vertical avoidance behavior of the tadpole madtom, as a surrogate to the northern madtom, in response to granular Bayluscide® when applied to control or assess larval sea lamprey populations.  The data set consists of one hour recordings of the avoidance behavior of tadpole madtoms after exposure to granular Bayluscide.  Each trial (replicated 15 times) consisted of three treated (Bayluscide granules) and three control (washed sand only) clear Plexiglas vertical columns (107 cm in height, 30.5 cm in diameter) with a single madtom per column.  Video recordings were analyzed for vertical avoidance at 30 second intervals after addition of Bayluscide granules/washed sand over a period of one hour.  Vertical migration of the normally bottom dwelling madtoms to greater than 15 centimeters off the bottom of the column was considered avoidance.

Inputs and Selected Outputs Used to Assess Spatial and Temporal Patterns in Streamflow, Water-Chemistry, and Aquatic Macroinvertebrates of Selected Streams in Fairfax County, Virginia, 2007-2018

Nitrogen (N), phosphorus (P), and suspended-sediment (SS) loads, in Fairfax County, Virginia streams have been calculated using monitoring data from five intensively monitored watersheds for the period from water year (October - September) 2008-2017. Nutrient and suspended-sediment loads were computed using a surrogate (multiple-linear regression) approach with lab analyzed N, P, and SS samples as the response variable and basic water-quality parameters (e.g. turbidity, specific conductance, pH, water temperature), streamflow, and time and seasonal terms that could be measured continuously as predictor (surrogate) variables. The load results represent the total mass of N, P, and SS that was exported from each of the Fairfax County watersheds. Trends in N, P, SS concentrations, as well as basic water-quality parameters including turbidity, water temperature, dissolved oxygen, specific conductance, and pH have been calculated using both non-flow-normalized and flow-normalized Seasonal Kendall tests at 14 monitoring stations in Fairfax County, Virginia for the period beginning April 2008 and ending March 2018. Flow-normalized trends were used to integrate out the effect of annual streamflow variability on concentration (or unit value). Streamflow is an important driver of water-quality conditions; therefore, several datasets are provided describing a suite of annual streamflow metrics: streamflow volume/yield, flashiness, peak stage, baseflow index, stormflow index, and runoff ratio. Depending on the metric, data are provided from the 5 intensively monitored Fairfax County, VA watersheds, the entire 20-station Fairfax County monitoring network (5 intensively monitored + 15 trend only monitoring stations), and/or 3 reference stations that are part of the USGS Chesapeake Bay Non-Tidal Network (USGS Station IDs 01646000, 01654000, 01658500). Streamflow analyses were conducted on data collected in water years 2008-2017 for all Fairfax County monitoring stations as well as station ID 01658500, 1948-2017 for station ID 01654000, and 1946-2017 for 01646000. Benthic macroinvertebrate data were collected annually (waters years 2008 - 2017) by Fairfax County staff from each of the 20 monitoring stations. These data were used to explore trends in 20 biological metrics; the data used to calculate these trends are provided.

Predicted relative habitat selection for migrating whooping cranes in the United States Great Plains, averaged

The whooping crane (Grus americana) is a listed, endangered species in North America, protected under federal legislation in the United States and Canada.  The only self-sustaining and wild population of Whooping Cranes nests at and near Wood Buffalo National Park near the provincial border of Northwest Territories and Alberta, Canada.  Birds from this population migrate through the Great Plains of North America and spend a nonbreeding period along the Gulf Coast of Texas at Aransas National Wildlife Refuge and surrounding lands.  These data represent predictions from a resource selection function using GPS locations between 2010 and 2016 during migration. This surface is a composite of drought and non-drought conditions calculated using the average drought occurrence at each pixel during our study period. Pixel values can be used to represent the relative probability of whooping crane use during migration, based on landscape conditions in 2020. These values should not be interpreted as absolute values of probability of use. See additional information about resource selection functions and interpretation of output as needed.

MODFLOW-2000 and MODPATH5 model data sets used to evaluate the effects of changes in pumping on regional groundwater-flow paths, 2005 and 2010, and areas contributing recharge to discharging wells, 1990-2010, in the vicinity of North Penn Area 7 Superfund site, Montgomery County, Pennsylvania: U.S. Geological Survey data release

A three-dimensional, groundwater-flow model (MODFLOW-2000) and a particle-tracking program 
(MODPATH5) were used to evaluate the effects of changes in pumping on regional groundwater-flow 
paths, 2005 and 2010, and areas contributing recharge to discharging wells, 1990-2010, in the vicinity 
of North Penn Area 7 Superfund site, Montgomery County, Pennsylvania. The steady-state model 
was used to simulate conditions for No Pumping, 1990, 2000, 2005, and 2010. The model was used to 
(1) evaluate the changes in flow paths from likely contaminant sources, and 
(2) delineate areas contributing recharge to streams and pumping wells. 
		
This USGS data release contains all of the input and output files for the simulations described in the 
associated report (https://doi.org/10.3133/sir20175014). The study modified and used the model 
documented in the publication 'Investigations of groundwater system and simulation of regional 
groundwater flow for North Penn Area 7 Superfund site, Montgomery County, Pennsylvania' by 
Lisa A. Senior and Daniel J. Goode (https://pubs.er.usgs.gov/publication/sir20135045).

Geochemical data for the Elk Creek alkaline complex, southeast Nebraska

This U.S. Geological Survey (USGS) data release contains analytical data from a suite of rock and mineral samples collected from drill core within the Elk Creek alkaline complex, southeast Nebraska. This complex hosts the Elk Creek carbonatite, a multilithologic carbonatite enriched in niobium, rare earth elements (REEs), scandium, and titanium.
Mineralized carbonatites are the world’s primary source of rare earth elements (REEs) and niobium, but only a few deposits are responsible for meeting the current demand of these critical elements such that there is increasing interest in other carbonatites that have the potential to help meet future demands. This study focuses on the Elk Creek carbonatite, the largest Nb resource in the United States and a REE exploration target. The Elk Creek carbonatite is comprised of three carbonatitic lithologies; apatite dolomite carbonatite, magnetite dolomite carbonatite, and barite dolomite carbonatite as well as multiple breccias. Samples were collected from drill core from mineral exploration holes drilled by the Molybdenum Corporation of America between 1973 and 1986. The drill cores are housed at the Nebraska Geological Survey storage facility near Lincoln, Nebraska.
Geochemistry data include major and trace element analytical results for 105 samples including alkaline igneous rocks, carbonatites, and paleosol samples. Dolomite and apatite geochemical data were collected using electron microprobe and laser ablation inductively coupled plasma-mass spectrometry (LA-ICP-MS) analyses. A set of dolomite samples were analyzed for their carbon and oxygen isotopic compositions. Data are reported in comma-separated values (CSV) files. All column headings, abbreviations, and limits of the data values are explained in the Entity and Attribute Information section of these metadata.

Baseline for the southern coast of Cape Cod, Massachusetts, generated to calculate shoreline change rates using the Digital Shoreline Analysis System version 5.1

The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast by compiling a database of historical (mid 1800's-1989) shoreline positions. Trends of shoreline position over long and short-term timescales provide information to landowners, managers, and potential buyers about possible future impacts to coastal resources and infrastructure.  In 2001, a 1994 shoreline was added to calculate both long- and short-term shoreline change rates along ocean-facing sections of the Massachusetts coast. In 2013, two oceanfront shorelines for Massachusetts were added using 2008-2009 color aerial orthoimagery and 2007 topographic lidar datasets obtained from the National Oceanic and Atmospheric Administration's Ocean Service (NOAA), Coastal Services Center. In 2018, two new mean high water (MHW) shorelines for the Massachusetts coast extracted from lidar data between 2010-2014 were added to the dataset. This 2021 data release includes rates that incorporate one new shoreline from lidar data extracted in 2018 by the U.S. Army Corps of Engineers (USACE) Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX), added to the existing database of all historical shorelines (1844-2014), for the North Shore, South Shore, Cape Cod Bay, Outer Cape, Buzzard’s Bay, South Cape, Nantucket, and Martha’s Vineyard. 2018 lidar data did not cover the Boston or Elizabeth Islands regions. Included in this data release is a proxy-datum bias reference line that accounts for the positional difference in a proxy shoreline (the High Water Line shoreline) and a datum shoreline (the Mean High Water shoreline). This issue is explained further in Ruggiero and List (2009) and in the process steps of the metadata associated with the rates. This release includes both long-term (~150+ years) and short term (~30 years) rates.  Files associated with the long-term rates have “LT” in their names, files associated with short-term rates have "ST” in their names.

Bathymetric data collected by the U.S. Geological Survey off the southern shore of Martha's Vineyard, MA, 2007 (ESRI BINARY GRID, BATHY_2M)

The USGS Woods Hole Science Center conducted a nearshore geophysical survey offshore of the southern coast of Martha's Vineyard, in the vicinity of the Martha's Vineyard Coastal Observatory (MVCO) in August 2007.  This mapping program was part of a larger research effort supporting the Office of Naval Research (ONR) Ripples Directed-Research Initiative (DRI) studies at MVCO by providing data collection and modeling.  The geophysical data will be used to provide initial conditions for wave and circulation models for the study area.  Ultimately, geophysical mapping, oceanographic measurements and modeling will help to improve our understanding of coastal sediment-transport processes.
The geophysical mapping utilized a suite of high-resolution instrumentation to map the surficial sediment distribution, depth and sub-surface geology: dual-frequency 100/500 KHz sidescan-sonar system, 234-KHz interferometric sonar, and 500 Hz -12 KHz chirp sub-bottom profiler. The survey was conducted aboard the M/V Megan Miller August 9-13, 2007. The study area covers 35 square kilometers from about 0.2 km to 5-km offshore of the south shore of Martha's Vineyard, and ranges in depth from ~ 5 to 20 meters.

Grain size and bulk density from Little Holland Tract and Liberty Island, Sacramento-San Joaquin Delta, California, 2015 to 2019 (ver. 4.0, March 2025)

Grain size distribution, bulk density, and percent carbon are reported for sediment samples from two flooded agricultural tracts, Little Holland Tract and Liberty Island, in the Sacramento-San Joaquin Delta, California. Samples were repeatedly collected at 8 sites using a Ponar grab or push core samplers during 19 visits to the study area from 2015 to 2019. The long-term time series data collection stations (sites LWA, HVB, HWC, and LVB) were sampled on almost every field survey, and the remaining sites were sampled 6 or times or fewer, some only once. All samples were analyzed for grain size distribution, and some were analyzed for bulk density and/or percent carbon. These data provide insight into how particle size distributions varied spatially and temporally.
