Shot point navigation at 500 shot intervals for EdgeTech SB-512i chirp seismic-reflection data collected by the U.S. Geological Survey - Woods Hole Coastal and Marine Science Center offshore of the Gulf Islands, MS, 2010 (ESRI point shapefile, 2010-012-FA_SeismicShot_500.shp)

In 2010, the U.S. Geological Survey in Woods Hole, MA and St. Petersburg, FL, in partnership with the U.S. Army Corps of Engineers, Mobile District conducted geologic mapping to characterize the seafloor and shallow subsurface stratigraphy offshore of the Gulf Islands of Mississippi. The mapping was carried out during two cruises in March, 2010 on the R/V Tommy Munro of Biloxi, MS. Data were acquired with the following equipment: an SEA Ltd SwathPlus interferometric sonar (both 234 kHz and 468 kHz systems), a Klein 3000 and a Klein 3900 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, high-resolution geologic maps and geophysical interpretations that can be utilized to identify sand resources within the region and better understand the Holocene evolution and anticipate future changes in this coastal system.

Location of 24 extensometers used to measure compaction in the Central Valley

This digital dataset describes the location of 21 extensometers used for observations of subsidence in 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.  Water levels, 
water-level altitude changes, and water-level and potentiometric-surface altitude maps; streamflows; 
boundary flows; subsidence; groundwater pumpage; water use; and water-delivery observations were 
used to constrain parameter estimates throughout the calibration of the CVHM.  Measured compaction 
from data collected by extensometers in the valley was used as a subsidence calibration target.  
Subsidence monitoring observations can provide valuable information about hydrologic parameters 
such as elastic and inelastic skeletal specific storage.  The CVHM was adjusted to fit the range of 
measured compaction at the extensometer sites utilizing UCODE-2005 (Poeter and others, 2006) 
and manual calibration.  The calibration target was the measured compaction from several extensometers 
in the region.  Compaction though delayed drainage and re-pressurizing of aquitards was not simulated. 
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).

Processed Continuous Resistivity Profile Data Collected in the Potomac River/Chesapeake Bay on Sept. 8, 2006

In order to test hypotheses about groundwater flow under and into Chesapeake Bay, geophysical surveys were conducted by U.S. Geological Survey (USGS) scientists on Chesapeake Bay and the Potomac River Estuary in September 2006. Chesapeake Bay resource managers are concerned about nutrients that are entering the estuary via submarine groundwater discharge, which are contributing to eutrophication.  The USGS has performed many related studies in recent years to provide managers with information necessary to make informed decisions about this issue.  The research carried out as part of the study described here was designed to help refine nutrient budgets for Chesapeake Bay by characterizing submarine groundwater flow and discharge of groundwater beneath part of the mainstem and a major tributary, the Potomac River Estuary.

Shot-Point Navigation (500 Shot Interval) for the Chirp High-Resolution Seismic-Reflection Profiles Collected During U.S. Geological Survey (USGS) R/V Rafael Cruise 08034 off Edgartown, Massachusetts (08034_KELNAV500.SHP)

The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA) and the Massachusetts Office of Coastal Zone Management (MA CZM), is producing detailed geologic maps of the coastal sea floor. Imagery, originally collected by NOAA for charting purposes, provides a fundamental framework for research and management activities along this part of the Massachusetts coastline, shows the composition and terrain of the seabed, and provides information on sediment transport and benthic habitat. Interpretive data layers were derived from the combined single-beam and multibeam echo-sounder data and sidescan-sonar data collected in the vicinity of Edgartown Harbor, Massachusetts.  During August 2008 seismic-reflection profiles (Boomer and Chirp) were acquired, and during September 2008 bottom photographs and surficial sediment data were acquired as part of two ground-truth reconnaissance surveys.

ASCII grid of bathymetry data collected by the U.S. Geological Survey and the National Oceanic and Atmospheric Administration offshore of Massachusetts between Duxbury and Hull with data gaps (DH_bathy_wgaps.asc, ARC/INFO ASCII GRID, UTM Zone 19, 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 Science Center (WHSC). 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 (5-30 m deep) of Massachusetts between the New Hampshire border and Cape Cod Bay. 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). This spatial dataset is from the study area located between Duxbury and Hull Massachusetts, and consists of high-resolution geophysics (bathymetry, backscatter intensity, and seismic reflection) and ground validation (sediment samples, video tracklines and bottom photographs). The data were collected during four separate surveys conducted between 2003 and 2007 (NOAA survey H10993 in 2003, USGS-WHSC survey 06012 in 2006, and USGS-WHSC surveys 07001 and 07003 in 2007) and cover more than 200 square kilometers of the inner continental shelf.

Projections of coastal flood water elevations for the U.S. Atlantic coast

Projected water elevations from compound coastal flood hazards for future sea-level rise (SLR) and storm scenarios are shown for the U.S. Atlantic coast for three states (Florida, Georgia, and Virginia). Projections were made using a system of numerical models driven by output from Global Climate Models (GCMs) from the Coupled Model Intercomparison Project Phase 6 (CMIP6) and a tropical cyclone database from U.S. Army Corps of Engineers. The resulting data are water elevations of projected flood hazards along the U.S. Atlantic coast due to sea-level rise and plausible future storm conditions that consider the changing climate, hurricanes, and natural variability. The resulting data products include water elevations that are consistent with coastal flood projections, also available in this dataset (Barnard, and others, 2023); see Nederhoff and others (2024) for a full explanation of data and methods. In addition to sea-level rise, flood simulations run by these numerical models included dynamic contributions from tide, storm surge, wind, waves, river discharge, precipitation, and seasonal sea-level fluctuations. Outputs include impacts from combinations of SLR scenarios (0, 0.25, 0.5, 1.0, 1.5, 2.0, and 3.0 m), storm conditions including 1-year, 20-year, and 100-year return interval storms, and a background condition (no storm - astronomic tide and average atmospheric conditions). Similar projections for North Carolina and South Carolina are available from Barnard and others, 2023, at https://doi.org/10.5066/P9W91314

Sedimentary Data Collected in April 2013 From Dauphin Island and salt marshes of coastal Alabama

From April 13 to 20, 2013, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) collected push cores and vibracores on Dauphin Island, Alabama, along with push and auger cores in salt marshes at several locations in southwestern coastal Alabama. This work, a component of the SPCMSC’s Barrier Island Evolution Research (BIER) project, was conducted as part of USGS field activity number (FAN) 13BIM01. The objectives of the study were to evaluate processes affecting the development and evolution of certain back-barrier environments (marsh, flats, ponds, etc.) and to assist in developing geologic controls on barrier island breaching.  In addition to the collection of sediment cores, marsh surface sediments were collected for micropaleontological analysis (included in this report). Ground penetrating radar (GPR) was collected on Dauphin Island and adjacent barrier-island environments. Elevation-corrected subsurface profile images of the processed GPR data, unprocessed digital GPR trace data, post-processed differential Global Positioning System (DGPS) data, and Geographic Information System (GIS) files are reported in Forde and others (2016, https://doi.org/10.3133/ds982).
This data report is an archive of field-collected and laboratory analytical data for the sediment cores and surface sediments.  Data products include: GPS-derived site locations and elevations; core logs and photographs; lithologic, radiochemical, elemental composition, stable isotopic composition, micropaleontological data; and Federal Geographic Data Committee (FGDC) metadata.

Raw Continuous Resistivity Profiles Collected in the Neuse River, April 22, 2004

The Neuse River Estuary in North Carolina is a broad, V-shaped water body located on the southwestern end of Pamlico Sound. This estuary suffers from severe eutrophication for which several water quality models have recently been developed to aid in the management of nutrient loading to the estuary. In an effort to help constrain model estimates of the fraction of nutrients delivered by direct ground-water discharge, continuous resistivity profile (CRP) measurements were made during the spring of 2004 and 2005. CRP is used to measure electrical resistivity of sediments, a property that is sensitive to difference in salinity of submarine ground water. The 2004 and 2005 surveys used floating resistivity streamers of 100 m and 50 m respectively. The depth penetration of the streamers is approximately 20% of the streamer length which translates to approximately 20-25 m with the 100 m streamer and 12-14 m with the 50 m streamer. These data were processed using AGI's EarthImager 2D software. CRP data enables the mapping of the extent and depth of the fresher ground water within the estuary.
