New Mexico Elk Jemez Stopovers

The Jemez elk herd resides in the Jemez Mountains within the Valles Caldera National Preserve. This herd was originally included in Ungulate Migrations of the Western United States, Volume 2 (Kauffman and others, 2022), but has been updated for this volume owing to the acquisition of new data from 40 additional adult females. The Jemez elk are only partially migratory, with some residents remaining within the Valles Caldera year-round, while others exhibit two distinct seasonal movement patterns. The first movement pattern occurs during midwinter (January–February; arrows labeled 1) when numerous individuals move to the lower elevation slopes of the Valles Caldera, primarily southeast towards Bandelier National Monument. The second movement is more typical of a spring and fall migratory movement (arrows labeled 2), with individuals traveling north to La Grulla Plateau for the summer and returning to the Valles Caldera for winter. The primary challenge for migrating individuals is crossing State Route 4 when traveling to Bandelier National Monument.
These mapping layers show the location of stopovers for elk (&lt;i&gt;Cervus canadensis&lt;/i&gt;) in the Jemez population in New Mexico. They were developed from 179 migration sequences collected from a sample size of 122 animals comprising GPS locations collected every 3 to 6 hours.

40Ar/39Ar Isotopic Data and Ages for Rocks from the Yukon-Tanana Upland of Eastern Alaska and the Northern Aleutian Range of South-Central Alaska

This dataset contains 40Ar/39Ar isotopic data and ages for rocks from the Yukon-Tanana upland of eastern Alaska and the northern Aleutian Range of south-central Alaska. The entire sample suite was collected as part of geological mapping and supporting geochemical and geochronological analysis were conducted from 2013 to 2019 by the Mineral Resources Program of the U.S. Geological Survey (USGS). Legacy bedrock samples archived from earlier USGS field investigations were also analyzed in some cases. Hornblende, muscovite, and (or) biotite were extracted from bedrock samples of igneous and metamorphic rocks and analyzed at the University of Alaska Fairbanks Geochronology Laboratory in order to determine the 40Ar/39Ar age of each mineral phase. The data tables accompanying this data release report the resulting 40Ar/39Ar analytical data and interpreted ages for each mineral separated from a bulk rock sample.

Hydrodynamic and Sediment Transport Model Application for OSAT3 Guidance: Locations of convergences in the maximum alongshore current

The U.S. Geological Survey has developed a method for estimating the mobility and potential alongshore transport of heavier-than-water sand and oil agglomerates (tarballs or surface residual balls, SRBs).  During the Deepwater Horizon spill, some oil that reached the surf zone of the northern Gulf of Mexico mixed with suspended sediment and sank to form sub-tidal mats. If not removed, these mats can break apart to form SRBs and subsequently re-oil the beach.  A method was developed for estimating SRB mobilization and alongshore movement.  A representative suite of wave conditions was identified from buoy data for April, 2010, until August, 2012, and used to drive a numerical model of the spatially-variant alongshore currents.  Potential mobilization of SRBs was estimated by comparing combined wave- and current-induced shear stress from the model to critical stress values for several sized SRBs. Potential alongshore flux of SRBs was also estimated to identify regions more or less likely to have SRBs deposited under each scenario.  This methodology was developed to explain SRB movement and redistribution in the alongshore, interpret observed re-oiling events, and thus inform re-oiling mitigation efforts.

MODFLOW 6 and MODPATH 7 model data sets used to evaluate groundwater flow in the vicinity of Horsham and Warminster, Bucks and Montgomery Counties, Pennsylvania-Preliminary simulations for conditions in 1999, 2010, 2013, 2016, and 2017

In cooperation with the U.S. Navy, USGS developed and calibrated a numerical 
MODFLOW 6 model to simulate regional groundwater flow under selected 
conditions during 1999-2017 at and near the former Willow Grove Naval Air 
Station Joint Reserve Base in Horsham, Montgomery County and the former 
Naval Air Warfare Center Warminster in Bucks County, Pennsylvania. The 
model simulations provide information on regional groundwater-flow paths 
and groundwater/surface-water exchanges, in relation to changes in water 
supply pumping and recharge rates. Groundwater flow paths were simulated 
using MODPATH 7 from possible PFAS sources at the former bases under 
steady-state conditions for years 1999, 2010, 2013, 2016, and 2017.  This 
USGS data release contains all of the input and output files for the model 
calibration and simulations described in the associated report 
(https://doi.org/10.3133/ofr20191137).

Orthomosaic images of the middle and lower Elwha River, Washington, 2012 to 2017

This dataset presents 28 georeferenced orthomosaic images of the middle and lower reaches of the Elwha River. Each mosaic image was created by stitching together thousands of individual photographs that were matched based on numerous unique tie points shared by the photographs. The individual photographs were taken by a plane-mounted camera during multiple flights over the study area spanning 2012 to 2017. Because each mosaic is orthogonal to the earth's surface and is georeferenced to real-world coordinates, changes to the river channel and surrounding morphology can be seen and measured, including channel width, river braiding, bar formation, and other metrics to assess responses of the river to the removal of two large dams upstream from the study area.

Raw continuous resistivity profile data collected by the U.S. Geological Survey in Great South Bay on Long Island, New York, on May 22, 2008

An investigation of submarine aquifers adjacent to the Fire Island National Seashore and Long Island, New York, was conducted to assess the importance of submarine groundwater discharge (SGD) as a potential nonpoint source of nitrogen delivery to Great South Bay. More than 200 kilometers (km) of continuous resistivity profiling (CRP) data were collected to image the fresh-saline groundwater interface in sediments beneath the bay. In addition, groundwater sampling was performed at sites (1) along the northern shore of Great South Bay, particularly in Patchogue Bay, that were representative of the developed Long Island shoreline, and (2) at sites on and adjacent to Fire Island, a 50-km-long barrier island on the southern side of Great South Bay. Other field activities included sediment coring, stationary electrical resistivity profiling, and surveys of in-situ pore water conductivity. The onshore and offshore shallow hydrostratigraphy of the Great South Bay shorelines, particularly the presence and nature of submarine confining units, appears to exert primary control on the dimensions and chemistry of the submarine groundwater flow and discharge zones. Sediment coring has shown that the confining units commonly consist of drowned and buried peat layers likely deposited in salt marshes. Based on CRP data, low-salinity groundwater extends from 10 to 100 meters (m) offshore along much of the northern and southern shores of Great South Bay, especially off the mouths of tidal creeks, and beneath shallow flats to the north of Fire Island adjacent to modern salt marshes. Human modifications of much of the shoreline and nearshore areas along the northern shore of the bay, including filling of salt marshes, construction of bulkheads and piers, and dredging of navigation channels, has substantially altered the natural hydrogeology of the bay's shorelines by truncating confining units and increasing recharge near the shore in filled areas. Better understanding of the nature of SGD along developed and undeveloped shorelines of embayments such as this could lead to improved models and mitigation strategies for nutrient overenrichment of estuaries.

Multivariate regression model for predicting oxygen reduction rates in groundwater for the State of Wisconsin

A multivariate regression model was developed to predict zero-order oxygen reduction rates (mg/L/yr) in aquifers across the State of Wisconsin. The model used a combination of dissolved oxygen concentrations and mean groundwater ages estimated with sampled age tracers from wells in the U.S. Geological Survey National Water Information System and previously published project reports from state agencies and universities.  The multivariate regression model was solved using the Microsoft Excel solver, with 461 wells used for training and 46 wells held-out for validation.  A total of 31 predictor variables were used for model development (56 were tested), including basic well characteristics, soil properties, aquifer properties, hydrologic position on the landscape, recharge and evapotranspiration rates, and land use characteristics. Model results indicate that the mean oxygen reduction rate for the training wells is 0.15 mg/L/yr (ranges from 0.07 to 0.59 mg/L/yr), with a root mean weighted square error of 3.13 mg/L/yr and Coefficient of Correlation (r^2) of 0.49 for the holdout validation data. This data release includes the Microsoft Excel file that represents the final solved regression model, as well as an Excel file that describes all of the predictor variables that were tested with the model.

Magnetotelluric data, Southern San Luis Valley, Colorado, 2006: Station 16

This dataset includes the magnetotelluric (MT) sounding data collected in 2006 in the Southern San Luis Valley, Colorado. The U.S. Geological Survey conducted a series of multidisciplinary studies, including MT surveys, in the San Luis Valley to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits comprising the principal groundwater aquifers of the Rio Grande rift. The shallow unconfined and the deeper confined Santa Fe Group aquifers in the San Luis Basin are the main sources of municipal water for the region. The population of the San Luis Valley region is growing rapidly and water shortfalls could have serious consequences. Future growth and land management in the region depend on accurate assessment and protection of the region's groundwater resources.

Time-Domain Electromagnetic Data Collected in the U.S. Part of the Mesilla Basin/Conejos-Médanos Aquifer System in Doña Ana County, New Mexico, and El Paso County, Texas, November 2012

The transboundary Mesilla Basin/Conejos-Médanos aquifer system was identified as one of the priority transboundary aquifer systems for additional study by the United States and Mexico U.S.-Mexico Transboundary Aquifer Assessment Act of 2006 (United States-Mexico Transboundary Aquifer Act, Public Law 109-448). As one of the largest rechargeable groundwater systems by total available volume in the Rio Grande/Rio Bravo del Norte Basin region of the United States and Mexico, the Mesilla Basin/Conejos-Médanos aquifer system supplies water for irrigation as well as municipal use in El Paso, Texas; Las Cruces, New Mexico; and Ciudad Juárez, Chihuahua, Mexico (Alley, 2013). The U.S. Geological Survey in cooperation with the Bureau of Reclamation assessed the groundwater resources in the Mesilla Basin and surrounding areas in Doña Ana County, New Mexico, and El Paso County, Texas by using a combination of geophysical and geochemical methods. Previously published geophysical data were compiled and these data were augmented by collecting additional geophysical and geochemical data. In October 2012, 12 time-domain electromagnetic soundings were collected near the southeastern part of the study area by the U.S. Geological Survey to provide more information on the area south of where the previously published direct-current resistivity soundings had been collected. Results from these geophysical assessments were used with collected geochemical data to facilitate the interpretation of the geochemical characteristics of the groundwater sources and the identification of geochemical groups within the aquifer, physical and geochemical description of the groundwater-flow system and the evolution of the groundwater from source to mixing, location of discharge areas, and definition of some of the salinity issues relative to the Rio Grande.

Water Table Contours in the Upper Glacial and Magothy Aquifers, April-May 2016

This polyline shapefile consists of digital contours that represent the water table altitude in the upper glacial and Magothy aquifer beneath Long Island, New York. The U.S. Geological Survey constructed a water table altitude map using ground-water levels measured in the upper glacial and Magothy aquifers during the spring of 2016. Contours were constructed at a scale of 1:125,000 from water-level data collected at 276 groundwater monitoring wells. The water table altitude contours were digitized and compared to 1997, 2006, 2010 and 2013 water table altitude maps . The variable contour interval ranges from 5 to 120 feet above the National Geodetic Vertical Datum of 1929 (NGVD29). This polyline shapefile is a digital representation of the potentiometric-surface contours presented in sheet 1 of Scientific Investigations Map 3398.

Characterizing the early life history of an imperiled freshwater mussel (Ptychobranchus jonesi)

Conservation of imperiled species is frequently challenged by insufficient knowledge of life history and the environmental factors that affect various life stages. The larvae (glochidia) of most freshwater mussels in the family Unionidae are obligate ectoparasites of fishes. We describe the early life history of the federally endangered Southern Kidneyshell, Ptychobranchus jonesi, and compare methods for estimating fecundity and conducting host trials on conglutinate-producing mussel species. Both the glochidial inoculation baths and direct feeding of conglutinates to Percina nigrofasciata, Etheostoma edwini, and Etheostoma fusiforme resulted in successful metamorphosis to the juvenile life stage. Ptychobranchus jonesi glochidia did not metamorphose on the 25 other species of fishes tested representing 11 families. Three juveniles were recovered from Gambusia holbrooki resulting in a metamorphosis rate &lt; 1%. We characterize P. jonesi as a host fish specialist that fractionally releases conglutinates from late January to early June. Intact P. jonesi conglutinate resemble a simuliid fly larva attached to an egg, but the majority of conglutinates were released as segments representing separate egg-- or larva--mimics. Viability of glochidia encased within a conglutinate was &gt; 90% for at least 5 days. Directly feeding conglutinates to fishes allowed us to estimate natural infestation rates and calculate average numbers of juveniles produced per conglutinate, unlike the traditional approach of infesting fish hosts using an inoculation bath. Each method for measuring fecundity produced similar estimates but the regression, which estimated fecundity based on the physical dimensions of each conglutinate or conglutinate segment, was most practical. The distribution information, coupled with early life history description and methods developed for determining fecundity and conducting host trials, may assist in the conservation of P. jonesi, specifically during recovery options that include captive propagation, augmentation, and reestablishment.
