Data Release for Prospectivity Mapping for Geologic Hydrogen

This data release contains multiple data layers and describes the processing steps associated with the U.S. Geological Survey Professional Paper 1900  "Prospectivity Mapping for Geologic Hydrogen". The data comprise the geologic and geophysical inputs used in support of the U.S. Geological Survey's efforts to create the first map of geologic hydrogen prospectivity within the U.S. The maps are based on our understanding of the geologic hydrogen system model, which includes three primary components: 1) a source of natural hydrogen, 2) a reservoir to store hydrogen in the subsurface, and 3) a competent seal to retain the hydrogen and prevent leakage to the Earth’s surface. Collectively, the data release includes 44 raster files and 2 data tables. In addition to this metadata file, see the larger work of Gelman, Hearon, and Ellis (USGS PP1900) for detailed descriptions of the individual layers used for mapping and the mathematical approach used for risking and modeling.

Passive seismic depth to bedrock data collected along the Slate River floodplain, CO, USA 2021

Using the horizontal-to-vertical spectral-ratio (HVSR) method, we inferred the depth to bedrock at the Slate River Floodplain, CO, USA. The point-scale passive seismic data were collected using Model TEP-3C Tromino seismometers over 20 min or less intervals with the instruments coupled directly to the floodplain ground surface at 42 non-flooded locations during June 2021. The ratio of horizontal-to-vertical Fourier spectra (HVSR), determined using Grilla software (MOHO, S.R.L.), along with the estimated sediment shear-wave velocity, was used to calculate the depth to the bedrock contact. This passive seismic dataset indicates that the deepest bedrock is 16 m below the surface, while the bedrock reaches the surface at the hillslope. This release contains the inferred bedrock depths based on likely shear wave velocities (Vs) intrinsic to the underlying sediment, ranging from 300 m/s to 400 m/s, listed in the processed_data subdirectory in the file 'SLAC_HVSR_June2021.csv.'  The range of possible depth to bedrock interpretations is included for demonstration purposes only.

2002 Survey of Diamondback Terrapins in the Chesapeake Bay

The survey was conducted to assess the distribution of terrapins in the Chesapeake Bay, based on evidence related to nesting. We conducted a survey of the beaches during the nesting season in the summer of 2002. We walked along the shoreline of over 1350 beach segments looking for evidence signifying the presence of terrapins based on nesting activity. These results represent a single-season snapshot of conditions during the surveys and at the locations visited during that season; it should not be assumed that this is representative of terrapin nest locations and numbers today.

Point Shapefile of Electrical Conductance Geoprobe Locations Collected in August, 2005 in the Nauset Marsh Area of Cape Cod, Massachusetts

In order to test hypotheses about groundwater flow under and into estuaries and the Atlantic Ocean, geophysical surveys, geophysical probing, submarine groundwater sampling, and sediment coring were conducted by U.S. Geological Survey (USGS) scientists at Cape Cod National Seashore (CCNS) from 2004 through 2006. Coastal resource managers at CCNS and elsewhere are concerned about nutrients that are entering coastal waters via submarine groundwater discharge, which are contributing to eutrophication and harmful algal blooms. The research carried out as part of the study described here was designed, in part, to help refine assumptions required by earlier versions of models about the nature of submarine groundwater flow and discharge at CCNS. This study was conducted in four phases, with a variety of field techniques and equipment employed in each phase. Phase 1 consisted of continuous resistivity profiling (CRP) surveys of the entire study area conducted in 2004. Phase 2 consisted of CRP ground-truthing via resistivity probe measurements and submarine groundwater sampling from hydraulically-drive piezometers using a barge in the Salt Pond/Nauset Marsh area in 2005. Phase 3 consisted of supplemental detailed CRP surveys in the Salt Pond/Nauset Marsh area in 2006. Finally, Phase 4 consisted of sediment coring and porewater extraction in the Salt Pond/Nauset Marsh area later in 2006 to supplement the 2005 sampling.

Hawaiian Volcano Observatory Earthquake Catalog for the region around Mauna Loa 2009-2023

Catalog datasets in support of publication, "A Decade of Precursory Seismicity at Mauna Loa: 2013-2022". The earthquake catalogs begin April 1, 2009 and extend to January 1, 2023.  The entire dataset has been generated with the ANSS Quake Management System (AQMS), which has the real-time software package Earthworm at its core.  Automated and reviewed locations use the Hypoinverse location program and data is given in Hypoinverse format.  One catalog contains all earthquakes within the catalog, regardless of whether the locations have been reviewed or not.  There is no mechanism in the Hypoinverse format to distinguish a reviewed from an automated event.  The second catalog consists only of earthquakes reviewed by a seismic analyst.  Both catalogs contain earthquakes within 45 kilometers of the summit of Mauna Loa.

Vegetation Transects to Measure Effects of Snow Goose Grazing on the Colville River Delta, Alaska

This data release corresponds to visual vegetation measurements in snow goose grazing areas of the Colville River Delta. Visual vegetation measurements data include functional group percent cover and evidence of goose activity including grazed stems, snow goose grubbing holes, and shoot pulling. These data were collected at a set of four 100m transects located in areas of representative vegetation used by nesting snow geese on the Colville River Delta. The transects were distributed non-randomly in an area with sparse snow goose nesting but adjacent to an existing snow goose nesting colony in 2016, to provide baseline vegetation data that could be compared to future surveys as the snow goose nesting population grew and expanded its spatial footprint. At each transect, vegetation measurements were collected within 11 50cm by 50cm quadrats located every 10m along the transect line. At every observation, two photographs were taken at every plot. One was an overhead shot from ~1m height, and the second was a landscape shot showing the immediate vicinity of the plot. All photographs are indexed in the data table.

Seamless Integrated Geologic Map Database of the Intermountain West: Contributions to The National Geologic Map

This dataset is intended to provide seamless, integrated, surficial geologic mapping of the U.S. Intermountain West region and is supported by the National Cooperative Geologic Mapping Program of the U.S. Geological Survey. Surficial geology included as part of this data release as independent of bedrock geologic mapping and is compiled at a variable resolution from 1:50,000 to 1:250,000 scale. No original interpretations are presented in this dataset; rather, all interpretive data are assimilated from referenceable publications.
Initial contributions to this data release are along an east-west transect that parallels 37-degrees north latitude extending from the Rio Grande Rift and Great Plains in the east to the Basin and Range and Sierra Nevada to the west. Other areas of the Intermountain West region will be incorporated over time. Data are presented as a downloadable file geodatabase (*.gdb) and as features services that can be directly ingested into GIS software for analysis. This dataset is intended to be versioned regularly as new geologic map data is integrated. The data structure follows the Seamless Integrated Geologic Mapping extension (SIGMa) (Turner and others, 2022) to the Geologic Map Schema (GeMS) (USGS, 2020).

MOSAIC8 - Composite sidescan-sonar mosaic collected by the U.S. Geological Survey offshore of the Chandeleur Islands, LA, 2007 (UTM Zone 16N GeoTIFF)

In 2006 and 2007, the U.S. Geological Survey, in partnership with Louisiana Department of Natural Resources and the University of New Orleans, conducted geologic mapping to characterize the sea floor and shallow subsurface stratigraphy offshore of the Chandeleur Islands in Eastern Louisiana. The mapping was carried out during two cruises on the R/V Acadiana. Data were acquired with the following equipment: an SEA Ltd SwathPlus interferometric sonar (234 kHz), Klein 3000 dual frequency sidescan sonar, and an Edgetech 512i chirp subbottom profiling system. The long-term goal of this mapping effort is to produce high-quality geologic maps and geophysical interpretations that can be utilized to investigate the impact of Hurricane Katrina in 2005 and to identify sand resources within the region.

Land use and socioeconomic time-series reveal legacy of redlining on present-day gentrification within a growing United States city.

Home Owners’ Loan Corporation (HOLC) maps illustrated patterns of segregation in United States cites in the 1930s. As the causes and drivers of demographic and land use segregation vary over years, these maps provide an important spatial lens in determining how patterns of segregation spatially and temporally developed during the course of the past century. Using a high-resolution land-use time series (1937-2018) of Denver Colorado USA, in conjunction with 80 years of U.S. Census data, we found divergent land-use and demographics patterns across HOLC categories were both pre-existent to the establishment of HOLC mapping, and continued to develop over time. Over this period, areas deemed “declining” or “hazardous” had more diverse land use compared “desirable” areas. “Desirable” areas were dominated by one land-use type (single-family residential), while single-family residential diminished in prominence in the “declining/hazardous” areas. This divergence became more established decades after HOLC mapping, with impact to racial metrics and low-income households. We found changes in these demographic patterns also occurred between 2000 and 2019, highlighting how processes like gentrification can develop from both rapid demographic and land-use changes. This study demonstrates how the legacy of urban segregation develops over decades and can simultaneously persist in some neighborhoods while providing openings for fast-paced gentrification in others.
