Geochemical and 40Ar/39Ar Analytical Data of Rocks from Glacier Bay National Park and Preserve

This dataset contains major and trace element geochemical data and 40Ar/39Ar isotopic data and ages for rock samples collected during 2016 fieldwork in Glacier Bay National Park and Preserve. The plutonic rock samples were collected for radiometric age determinations to test for the presence of the Late Jurassic to Early Cretaceous (130-160 Ma) Saint Elias suite. The age analyses indicate that all the dated plutons are too young to be included in the Saint Elias suite.

MODFLOW-2005 and MODPATH-6 Data sets of Simulated Groundwater Flow to Evaluate Wellbore Flow in Generic Long-Screened Wells Under Ambient Flow

A generic, three-dimensional finite-difference model, MODFLOW-2005 (version 1.12.00) and MODPATH-6 (version 6.0.01), 
was created to better understand the amount of vertical flow and cross-contamination of trichloroethene (TCE) that may be occurring 
in discontinued extraction wells under current (2018-19) ambient-flow conditions at site 25 of the Edwards Air Force Base, California. 
The wells are long-screened (100-ft long), contain a surrounding sandpack, and have not been pumped for approximately 10 years. 
The groundwater flow model utilized multiple observations made from the field measurements of flow and transport to conceptualize, 
calculate, and simulate in-well flow, and flow in the sand pack. The model was constructed to represent the average-flow condition 
near a typical long-screened well and was used to estimate flow in the sandpack and the wellbore and scenarios related to the 
hypothetical sealing of the interior of the well but leaving the sandpack intact. Relative estimates of vertical hydraulic conductivity 
between the wellbore and sandpack guided simulations. This study provided unique insights into ambient flow in long-screened wells set in 
low hydraulic conductivity aquifers that allowed for an improved assessment of remedial strategies to help mitigate cross-contamination of 
TCE. Understanding the dynamics of flow between the well and sandpack is needed to make informed decisions to mitigate contamination where 
the wellbores are facilitating the spread of contaminants through cross contamination under ambient-flow conditions. Three simulations were done 
including a simulation with no well, a simulation with the well open and unpumped with a surrounding sandpack, and a simulation with the 
well sealed with a liner but the sandpack left intact. Further information on the generic model is described in the journal article 
(https://doi.org/10.1007/s12665-024-11828-3). This USGS data release contains all the input and output files for the simulations described in the associated 
journal article.

Electromagnetic Induction, Gamma and Fluid Logs from Shallow Boreholes at the Callahan Mine Site: May 2017

From October 2016 to July 2018, the U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers and Maine Department of Transportation, collected surface, marine and borehole geophysical surveys to characterize the subsurface materials on land and under the water at a former mine facility in Brooksville, Maine. Borehole geophysical logs were collected in five boreholes from May 2-3, 2017 to identify geophysical properties, including the electrical properties and natural gamma emissions, which can be related to geologic materials behind casing.  In addition, fluid electrical conductivity and temperature were collected through the water column in the well. Results can be used to identify the water level and the lithologic contacts in the subsurface. Natural gamma, fluid electrical conductivity, temperature and electromagnetic induction logs are provided in a series of files within a compressed (zip) file. Equipment used, measurement units and calibration information are described in the log files.

Data Sets for the Report Entitled, "A Field Study of Selected U.S. Geological Survey Analytical Methods for Measuring Pesticides in Filtered Stream Water, June-September 2012"

The National Water-Quality Assessment (NAWQA) Program and National Stream Quality Accounting Network (NASQAN) are U.S. Geological Survey (USGS) monitoring programs that measure pesticide concentrations in the Nation’s streams and rivers, herein collectively referred to as streams. The NAWQA Program began monitoring pesticides in 1992 and the NASQAN Program began monitoring pesticides in 1995. The programs were recently merged to form the USGS National Water Quality Network for Rivers and Streams. Water samples are analyzed for pesticides by the USGS National Water Quality Laboratory (NWQL) using methods developed by the NWQL’s Methods Research and Development team. The NWQL extensively used two analytical methods, gas chromatography/mass spectrometry and liquid chromatography/mass spectrometry, to measure pesticides in filtered water samples during 1992–2012 (old method). In October 2012, the monitoring programs began using direct aqueous-injection liquid chromatography tandem mass spectrometry as a new analytical method for pesticides (new method). The change in analytical methods, however, has the potential to inadvertently introduce bias in analysis of datasets that span the change. The data sets provided in this report were used to document performance of the new method in a variety of stream-water matrices and help quantify potential changes in measurement bias or variability that could be attributed to changes in analytical methods (Martin and others, 2016). Users should consult the report by Martin and others (2016) to understand how these data were collected and used. Measured concentrations and calculated recoveries of 281 pesticides and degradates in paired environmental background water samples and matrix spiked water samples collected at 48 stream-water sites from June 11, 2012 to September 6, 2012 are provided in seven tab-delimited ASCII files with relational database (RDB) format header. A tab-delimited ASCII file (DataDictionaryList.txt) listing DataSet attributes and RDB column formats is also included in this data release.

Coastwide Reference Monitoring System (CRMS) 2015 Site 0684 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 2015 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.

Seabed still images in JPEG format collected on Stellwagen Bank during U.S. Geological Survey field activity 2017-043-FA, aboard the R/V Auk, Aug. 22 and 23, 2017

This field activity is part of an effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000-scale) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. The data collected in this study will aid research on the ecology of fish and invertebrate species that inhabit the region. On August 22 and 23, 2017, the U.S. Geological Survey, in collaboration with the Stellwagen Bank National Marine Sanctuary, conducted a research cruise aboard the Sanctuary’s Research Vessel Auk, visiting 39 locations within the sanctuary. A customized Van Veen grab sampler (SEABOSS) equipped with a video camera and a conductivity, temperature, and depth (CTD) instrument was deployed in drift mode to collect sediment for grain-size analysis, video imagery of the seabed, and measurements of water column properties.

Raman spectral parameters of pyrolyzed samples for three types of graptolites

A series of gold tube pyrolysis experiments (72 hrs, 300–600 °C) conducted on a graptolite-rich lower Paleozoic marine shale generated pyrolysis residues for a comprehensive evaluation of the molecular and structural variability of three types of graptolite periderm, namely granular, non-granular, and nodular graptolite. Raman spectroscopy in combination with organic petrology and field emission scanning electron microscopy (FE-SEM) was used to evaluate the thermal evolution process. The three types of graptolite periderm were analyzed by Raman spectroscopy wherein point measurements were obtained after the maceral was identified and the location verified by organic petrology. Raman spectroscopy, a non-destructive and rapid microstructural analysis technique, has recently emerged as a powerful tool for assessing the thermal maturity of source rocks (Ferralis et al., 2016; Kelemen and Fang, 2001). Applicability of these Raman thermal proxies has been extended to various OM types by correlating the Raman spectral parameters with traditional thermal maturity proxies, such as reflectance and pyrolysis Tmax (Liu et al., 2013; Wilkins et al., 2014; Morga and Pawlyta, 2018), and has thus proven to be useful in determining thermal maturity.

KauaiN_shorelines - Shorelines of the northern coastal region of Kauai, Hawaii, from Haena to Moloaa, used in shoreline change analysis

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.  Shoreline vectors derived from historic and modern sources represent the low water mark (beach toe).
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.
