MODFLOW-2000 model used to illustrate the differences in flow paths and travel times when three-dimensional kriging is used to estimate the hydraulic conductivity distribution as compared to manual determinations of hydraulic conductivity distribution

A three-dimensional (3D) groundwater flow model of the glaciated sediments around Elkhart, Indiana 
was constructed as part of the U.S. Geological Survey Groundwater Resources Program using 
lithologic records from water well logs. Texture-based hydraulic conductivities were assigned to 
vertical intervals along each lithology record. A three-dimensional kriging program read texture-based 
hydraulic conductivity values for each vertical interval and calculated a continuous 3D distribution of 
hydraulic conductivity for the entire model domain. The model was calibrated to hydrologic conditions 
in May and June of 1979. The model was used to simulate groundwater flow paths from points of 
recharge to points of discharge. These flow paths were compared to flow paths generated by an 
existing model (https://pubs.usgs.gov/wri/1997/4204/report.pdf) that was constructed using a manual 
approach to create the hydraulic conductivity distribution and calibrated to the same hydrologic 
conditions. The model using the kriged hydraulic conductivity distribution had 30 vertically discretized 
layers, and the model using the the manually created hydraulic conductivity distribution had two 
vertically discretized layers. This USGS data release contains the model input and output files for 
the simulations described in the associated documentation report

JI_Q11.TIF - Johnston Island U.S. EEZ GLORIA sidescan-sonar data mosaic (11 of 16) (LCC, 50 m, WGS84)

In 1984, the U.S. Geological Survey (USGS), Office of Marine Geology, launched a program using the Geological LOng-Range Inclined Asdic (GLORIA) sidescan-sonar system to study the entire U.S. Exclusive Economic Zone (EEZ). From December 1990 through February 1991, the USGS and IOS (Institute of Oceanographic Sciences, U.K.) scientists conducted three surveys within the Johnston Atoll U.S. EEZ surrounding Johnston Island. The results of these surveys were 16 digital mosaics of a 2 degree by 2 degree area with a 50-meter pixel resolution.

DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Streams represented in study area

Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer 
system were developed to define an updated hydrogeologic framework as part of the U.S. 
Geological Survey Groundwater Resources Program. This map layer shows areal and 
linear water features of Florida, Georgia, South Carolina, and Alabama. The original file 
was produced by joining the individual State hydrography layers from the 1:2,000,000- scale 
Digital Line Graph (DLG) data produced by the USGS. This map layer was formerly 
distributed as Hydrography Features of the United States. This is a revised version of the 
January 2003 map layer.

1-m interval contours of smoothed multibeam bathymetry in western Massachusetts Bay map Quadrangle 3 (Q3_1MCTR.SHP)

The U.S. Geological Survey has conducted geologic mapping to characterize the sea floor offshore of Massachusetts.  The mapping was carried out using a Simrad Subsea EM 1000 Multibeam Echo Sounder on the Frederick G. Creed on four cruises conducted between 1994 and 1998.  The mapping was conducted in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and with support from the Canadian Hydrographic Service and the University of New Brunswick.
The long-term goal of this mapping effort is to produce high-resolution geologic maps and a Geographic Information System (GIS) project that presents images and grids of bathymetry, shaded relief bathymetry, and backscatter intensity data from these surveys that will serve the needs of research, management and the public.

GAK_Q58.TIF - Gulf of Alaska U.S. EEZ GLORIA sidescan-sonar data mosaic (28 of 30) (LCC, 50 m, WGS84)

GLORIA data for the Gulf of Alaska Exclusive Economic Zone (EEZ) were acquired during five cruises over a four year period. The first cruise conducted in 1986 (F-1-86-GA) surveyed an area of the north-central mosaic area and covered an area of approximately 40,000 square kilometers (sq km). The second two cruises (F-8-88-AA, F-9-88-WG) were conducted in 1988. One of the 1988 cruises (F-8-88-AA) focused on a survey of the Aleutian Arc. The eastern most portion of that survey extended outside of the Aleutian Arc survey area and covered an area of approximately 52,000 square kilometers (sq km) of seafloor on the western edge of the Gulf of Alaska. The final two cruises (F-6-89-GA, F-7-89-EG) were completed in 1989. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the seafloor. Thirty digital mosaics with a 50-meter pixel resolution were completed for the region.

One meter mosaic of acoustic backscatter data acquired using a SWATHplus-H interferometric sonar in Barnegat and Little Egg Inlets, New Jersey by the U.S. Geological Survey in 2012, and 2013 (GeoTIFF image, UTM 18N, WGS 84)

In 2011, the US Geological Survey in partnership with the New Jersey Department of Environmental Protection began a multidisciplinary research project to better understand the water quality in Barnegat Bay, New Jersey.  This back-barrier estuary is flushed by only three inlets and is experiencing degraded water quality, algal blooms, loss of seagrass, and increases in oxygen stress, macro algae, stinging nettles, and brown tide. The scale of the estuary and the scope of the problems within it necessitate a multidisciplinary approach that includes establishing the regional geology, its physical characteristics, and modeling how the estuary's morphology interacts to affect its water quality.
Scientists from USGS Coastal and Marine Geology Program offices in Woods Hole, Massachusetts, and St. Petersburg, Florida, began mapping the seafloor of the Barnegat Bay-Little Egg Harbor estuary in November 2011 and completed in September 2013. With funding from the New Jersey Department of Environmental Protection and logistical support from the USGS New Jersey Water Science Center, they collected data with a suite of geophysical tools, including swath bathymetric sonar for measuring seafloor depth, a sidescan sonar for collecting acoustic-backscatter data (which provides information about seafloor texture and sediment type), subbottom profiler for imaging sediment layers beneath the floor of the estuary, and sediment samples with bottom photographs for ground validation of the acoustic data.
More information about the individual surveys conducted as part of the Barnegat Bay Project can be found on the Woods Hole Coastal and Marine Science Center Field activity webpages:

Tabular data: Sediment Sample Locations Collected in September 2012 from the Northern Chandeleur Islands, Louisiana (U.S. Geological Survey Field Activity Number 12LGC02)

As part of the Barrier Island Evolution Research (BIER) project, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) collected sediment samples from the northern Chandeleur Islands in March and September 2012. The overall objective of this project, which integrates geophysical (bathymetric, seismic, and topographic) and sedimentologic data, is to better understand the depositional and erosional processes that drive the morphologic evolution of barrier islands over annual to interannual timescales (1 to 5 years). Between June 2010 and April 2011, in response to the Deepwater Horizon oil spill, the State of Louisiana constructed a sand berm extending more than 14 kilometers (km) along the northern Chandeleur Islands platform. The construction of the berm provided a unique opportunity to investigate how this new sediment source will interact with and affect the morphologic evolution of the barrier-island system. Data collected from this study will be used to describe differences in the physical characteristics and spatial distribution of sediments both along the axis of the berm and also along transects across the berm and onto the adjacent barrier island. Comparison of these data with data from subsequent sampling efforts will provide information about sediment interactions and movement between the berm and the natural island platform, improving our understanding of short-term morphologic change and processes in this barrier-island system.
This data series serves as an archive of sediment data collected in March and September 2012 from the Chandeleur Islands sand berm and adjacent barrier-island environments. Data products, including descriptive core logs, core photographs and x-radiographs, results of sediment grain-size analyses, sample location maps, and Geographic Information System (GIS) data files with accompanying formal Federal Geographic Data Committee (FDGC) metadata, can be downloaded from http://pubs.usgs.gov/ds/850/data.html.

Spatial Provinces and Domains of the Central Valley for Textural Analysis

This digital dataset contains the 9 major areas used to subdivide the Central Valley for the interpolation of the 
percentage of coarse-grained deposits into the texture model.  This texture model was used as input data for 
the hydraulic properties portion of the Central Valley Hydrologic Model (CVHM).  The Central Valley encompasses 
an approximate 50,000 square-kilometer region of California. The complex hydrologic system of the Central 
Valley is simulated using the USGS numerical modeling code MODFLOW-FMP (Schmid and others, 2006).  
This simulation is referred to here as the CVHM (Faunt, 2009). Utilizing MODFLOW-FMP, the CVHM simulates 
groundwater and surface-water flow, irrigated agriculture, land subsidence, and other key processes in the Central 
Valley on a monthly basis from 1961-2003.  The total active modeled area is 20,334 square-miles on a finite 
difference grid comprising 441 rows and 98 columns. Slightly less than 50 percent of the cells are active. The 
CVHM model grid has a uniform horizontal discretization of 1x1 square mile and is oriented parallel to the valley 
axis, 34 degrees west of north (Faunt, 2009). In order to better characterize the aquifer-system deposits, lithologic 
data from approximately 8,500 drillers' logs of boreholes ranging in depth from 12 to 3,000 feet below land surface 
were compiled and analyzed. The percentage of coarse-grained sediment, or texture, then was computed for each 
50-foot depth interval of the drillers' logs. A 3-dimensional texture model was developed by interpolating the percentage 
of coarse-grained deposits onto a 1-mile spatial grid at 50-foot-depth intervals from land surface to 2,800 feet below 
land surface. The CVHM is the most recent regional-scale model of the Central Valley developed by the U.S. Geological 
Survey (USGS).  The CVHM was developed as part of the USGS Groundwater Resources Program (see "Foreword", 
Chapter A, page iii, for details).
