AndreaBozzo/ceres-open-data-index huggingface dataset:
Digital data sets that describe aquifer characteristics of the Antlers aquifer in southeastern Oklahoma

This data set consists of digitized polygons of a constant
hydraulic conductivity value for the Antlers aquifer in
southeastern Oklahoma. The Early Cretaceous-age Antlers
Sandstone is an important source of water in an area that
underlies about 4,400-square miles of all or part of Atoka,
Bryan, Carter, Choctaw, Johnston, Love, Marshall, McCurtain, and
Pushmataha Counties. The Antlers aquifer consists of sand, clay,
conglomerate, and limestone in the outcrop area. The upper part
of the Antlers aquifer consists of beds of sand, poorly cemented
sandstone, sandy shale, silt, and clay. The Antlers aquifer is
unconfined where it outcrops in about an 1,800-square-mile area.
The hydraulic conductivity polygons were developed from the
hydraulic conductivity value used as input into a ground-water
flow model and from published digital data sets of the surficial
geology of the Antlers Sandstone except in areas overlain by
alluvial and terrace deposits near streams. Some of the lines
were interpolated where the Antlers aquifer is overlain by
alluvial and terrace deposits. The interpolated lines are very
similar to the aquifer boundaries shown on maps published in a
ground-water modeling report for the Antlers aquifer. The
constant hydraulic conductivity value used as input to the
ground-water flow model was estimated as 5.74 feet per day.
Ground-water flow models are numerical representations that
simplify and aggregate natural systems. Models are not
unique; different combinations of aquifer characteristics may
produce similar results. Therefore, values of hydraulic
conductivity used in the model and presented in this data set
are not precise, but are within a reasonable range when
compared to independently collected data.

DS-777 Thickness-Weighted Average of Hydraulic Conductivity and Specific Yield for the Northern High Plains Groundwater-Flow Model in Parts of Colorado, Kansas, Nebraska, South Dakota, and Wyoming

This dataset is one of many developed in support of The High Plains Groundwater Availability Project 
 and the U.S. Geological Survey Data Series Report: Geodatabase Compilation of Hydrogeologic, 
Remote Sensing, and Water-Budget-Component data for the High Plains aquifer, 2011 (DS777). 
		
This dataset represents a thickness-weighted average of hydraulic conductivity (K) and specific 
yield (Sy) for 4,309 well points in the northern High Plains aquifer.  Hydraulic conductivity is a 
measure of how much water flows through a unit section of an aquifer, under a unit gradient in 
a specified amount of time.  Specific yield is a measure of how much water will drain from the 
aquifer by gravity. Both of these properties are important to develop a hydrogeologic framework 
for an aquifer and to gain an understanding of how water flows through the aquifer.
		
Included in this metadata document are the attribute definitions of all tables related to the feature 
class pts_K_Sy_TWA, including tbl_K_Sy_RawDataMaster a table of well point lithology records 
that terminate at the base of the aquifer. This document also includes the attribute definitions of 
the table of subsurface material, called tbl_Material that contains texture, grain-size, and sorting 
properties of the aquifer material, and the attribute definitions of the table of multipliers called 
tbl_Multiplier, which, based on certain subsurface materials, would reduce the computed values 
of these properties. The two tables, tbl_Material and tbl_Multiplier are used in the Geoparm 
macro to compute the K and Sy values at the wells in the pts_K_Sy_TWA feature class.  
Attribute definitions for tbl_K_Sy are also included in this metadata document; tbl_K_Sy is the 
output table created by the Geoparm macro.  The thickness weighted averages of K and Sy are 
computed by queries in this table after the macro is run. The thickness weighted averages were 
then transferred to the point feature class. (pts_K_Sy_TWA).

SECRU1M.TIF - Southeast Santa Cruz sidescan sonar backscatter image in nearshore Benthic Habitat mapping Project S. California map Series. (UTM 10N, NAD83)

The sidescan sonar image of the nearshore seafloor (0 to 100 m water depths) of the Southeast Santa Cruz area was mosaicked from data collected in 1999.  A Klein 2000 sidescan system was used for geophysical surveying. A Triton Elics Isis brand side-scan data recording system was used on the cruise.  The 1998 survey was navigated with a Leica Differential Global Positioning System (DGPS) which provided a ship position with accuracy of 1-5 m in DGPS mode. At times during the cruise differential signal was interrupted. In non-differential mode, the receiver provided a position with 30-50 m accuracy. A KVH Industries Inc. azimuth digital gyro-compass provided ship headings with 0.5 degree accuracy. Navigation data were recorded using Yo-Nav (Gann, 1992). The sidescan fish was towed approximately 30 m above the seafloor. The distance of the fish behind the ship was not known during this survey and must be estimated when the data are processed in order to produce the sidescan image mosaics.  The resolution of the processed data mosaics is 0.2 m. The data are presented here at a resolution of 1 m. This is one of a collection of digital files of a geographic information system of spatially referenced data related to the USGS Coastal and Marine Geology Program Nearshore Benthic Habitat Mapping Project. The sidescan data were processed using USGS MIPS sonar processing software (Chavez, 1984).  See &lt;http://walrus.wr.usgs.gov/nearshorehab&gt; for more information about this data set.

Bathymetric Terrain Model of the Puerto Rico Trench and Northeastern Caribbean Region Compiled by the U.S. Geological Survey From Multibeam Bathymetric Data Collected Between 2002 and 2013 (PRBATHOFR150, Esri Binary Grid, UTM19, WGS 84).

Bathymetric terrain models (BTMs) of seafloor morphology are an important component of marine geological investigations. Advances in technologies of acquiring and processing bathymetric data have facilitated the creation of high-resolution bathymetric surfaces that approach the resolution of those available for onshore investigations. These bathymetric terrain models provide a detailed representation of the Earth's subaqueous surface and when combined with other geophysical and geologic datasets, allow for interpretation of modern and ancient geologic processes.

Boomer Seismic Survey Tracklines - Lake Mead 2001

Lake Mead is a large interstate reservoir located in the Mojave Desert of southeastern Nevada and northwestern Arizona.  It was impounded in 1935 by the construction of Hoover Dam and is one of a series of multi-purpose reservoirs on the Colorado River.  The lake extends 183 km from the mouth of the Grand Canyon to Black Canyon, the site of Hoover Dam, and provides water for residential, commercial, industrial, recreational, and other non-agricultural users in communities across the southwestern United States.  Extensive research has been conducted on Lake Mead, but a majority of the studies have involved determining levels of anthropogenic contaminants such as synthetic organic compounds, heavy metals and dissolved ions, furans/dioxins, and nutrient loading in lake water, sediment, and biota (Preissler, et al., 1998; Bevans et al, 1996; Bevans et al., 1998; Covay and Leiker, 1998; LaBounty and Horn, 1997; Paulson, 1981).  By contrast, little work has focused on the sediments in the lake and the processes of deposition (Gould, 1951).  To address these questions, sidescan-sonar imagery and high-resolution seismic-reflection profiles were collected throughout Lake Mead by the USGS in cooperation with researchers from University of Nevada Las Vegas (UNLV).  These data allow a detailed mapping of the surficial geology and the distribution and thickness of sediment that has accumulated in the lake since the completion of Hoover Dam.  Results indicate that the accumulation of post-impoundment sediment is primarily restricted to former river and stream beds that are now submerged below the lake while the margins of the lake appear to be devoid of post-impoundment sediment.  The sediment cover along the original Colorado River bed is continuous and is typically greater than 10 m thick through much of its length.  Sediment thickness in some areas exceeds 35 m while the smaller tributary valleys typically are filled with less than 4 m of sediment.  Away from the river beds that are now covered with post-impoundment sediment, pre-impoundment alluvial deposits and rock outcrops are still exposed on the lake floor.

Single-Beam Bathymetry Sounding Data of Tampa Bay, Florida (2001-2004) in X,Y,Z format

Tampa Bay and its environs have experienced phenomenal urban growth and significant changes in land-use practices over the past 50 years. This trend is expected to continue, with human activity intensifying and affecting a wider geographic region. Urbanization has created impervious surfaces, which increase storm water run-off and contribute to higher levels of chemicals flowing into the area's waters. These chemicals have contributed to declines of sea-grasses and other marine life. A major focus of the USGS CMGP Tampa Bay Study was to investigate sediments and their associated contaminants, and to develop a bay wide circulation model to determine the routes of sediment transport.
High resolution sea floor mapping was conducted in Tampa Bay between 2001 and 2004 as part of the CMGP Tampa Bay Study. High resolution, acoustic bathymetric surveying is a proven method to map sea and estuary elevations. Data was collected throughout the entire bay including all small, peripheral embayments and channels.
This report serves as an archive of processed single-beam bathymetry data that were collected in Tampa Bay, Florida in 2001-2004. Geographic information system data products include a XYZ data, bathymetric contours, and USGS quadrangle map. Additional files include formal Federal Geographic Data Committee (FGDC) metadata.

Locations of bottom photographs collected by the U.S. Geological Survey offshore of Massachusetts within northern Cape Cod Bay (CCB_BOTTOMPHOTOS Esri Shapefile, Geographic, WGS84).

These data were collected under a cooperative agreement with the Massachusetts Office of Coastal Zone Management (CZM) and the U.S. Geological Survey (USGS), Coastal and Marine Geology Program, Woods Hole Coastal and Marine Science Center (WHCMSC). Initiated in 2003, the primary objective of this program is to develop regional geologic framework information for the management of coastal and marine resources. Accurate data and maps of sea-floor geology are important first steps toward protecting fish habitat, delineating marine resources, and assessing environmental changes due to natural or human impacts. The project is focused on the inshore waters of coastal Massachusetts, primarily in water depths of 3-30 meters deep. Data collected for the mapping cooperative have been released in a series of USGS Open-File Reports (http://woodshole.er.usgs.gov/project-pages/coastal_mass/html/current_map.html). The data collected in the study area located in Northern Cape Cod Bay Massachusetts includes high-resolution geophysics (bathymetry, backscatter intensity, and seismic reflection), and ground validation (sediment samples, video tracklines, and bottom photographs). The data were collected during five separate surveys conducted between 2006 and 2008 and cover 480 square kilometers of the inner continental shelf.
