SVANHAB -- Habitat polygons for the nearshore Point Arguello study area, South Vandenberg Reserve

Benthic habitat polygon coverages have been created for marine reserve locations surrounding the Santa Barbara Basin.  Diver, ROV and submersible video transects, bathymetry data, sedimentary samples, and sonar mapping, have been integrated to describe the geological, biological, and oceanographic aspects of habitat.  The U.S. Geological Survey (USGS), in a cooperative project with Sea Grant-MERRP and investigators at National Marine Fisheries Service (NMFS), the Channel Islands National Marine Sanctuary (CINMS), and National Park Service (NPS) has collected sidescan sonar and video data to produce a polygon coverage.  The habitat polygons have attributes for megahabitat, bottom induration, macrohabitat (where macrohabitat observations are available), polygon area, polygon perimeter, and water depth.  The habitat GIS shows rocky habitat suitable for rockfish (Sebastes sp.), abalone (Haliotis sp.), and other threatened benthic species from the shoreline out to the 100-m depth limit of the survey.

Attributes for MRB_E2RF1 Catchments by Major River Basins in the Conterminous United States: Level 3 Ecoregions

This tabular data set represents the estimated area of level 3 ecological landscape regions (ecoregions), 
as defined by Omernik (1987), compiled for every MRB_E2RF1 catchment of the Major River Basins 
(MRBs, Crawford and others, 2006). The source data set is Level III Ecoregions of the Continental 
United States (U.S. Environmental Protection Agency, 2003).
		
The MRB_E2RF1 catchments are based on a modified version of the U.S. Environmental Protection 
Agency's (USEPA) ERF1_2 and include enhancements to support national and regional-scale 
surface-water quality modeling (Nolan and others, 2002; Brakebill and others, 2011).
		
Data were compiled for every MRB_E2RF1 catchment for the conterminous United States covering 
New England and Mid-Atlantic (MRB1), South Atlantic-Gulf and Tennessee (MRB2), the Great Lakes, 
Ohio, Upper Mississippi, and Souris-Red-Rainy (MRB3), the Missouri (MRB4), the Lower Mississippi, 
Arkansas-White-Red, and Texas-Gulf (MRB5), the Rio Grande, Colorado, and the Great basin (MRB6), 
the Pacific Northwest (MRB7) river basins, and California (MRB8).

Shot points (60 shot interval) for CHIRP seismic profiles 15-27 collected on GYRE cruise 99002 (L15_27SP.SHP)

This GIS overlay is a component of the U.S. Geological Survey, Woods Hole Science Center's, Gulf of Mexico GIS database.  The Gulf of Mexico GIS database is intended to organize and display USGS held data and provide on-line (WWW) access to the data and/or metadata.
A two week cruise aboard the R/V GYRE focused on mapping surficial sedimentary processes and their connection to the subsurface geology.  The study area was on the upper continental slope in the northwestern Gulf of Mexico; an area of active hydrocarbon exploration. Active salt movement, hydrocarbon movement up faults, the presence of gas hydrates associated with biogenic and thermogenic methane, and overpressured sand deposits all present hazards to oil exploration in this area.  This study used sidescan sonar and high-resolution chirp subbottom profiling techniques to map the surficial and shallow subsurface expression of these processes in two areas roughly 15 by 25 km in size.  High-resolution multi-channel seismic-reflection data were collected simultaneously with the sidescan imagery to provide a link to the deeper subsurface. Additional multi-channel and Huntec seismic data were collected along regional lines between the detailed study areas to tie these studies to other areas of known hydrates and to wells where shallow overpressured sands have been drilled.
The detailed studies attempted to map entire geological systems in this upper slope environment to provide a broader perspective than can be seen from studying a single lease block.  One study area focused on two adjacent salt withdrawal basins to assess the processes that are shaping the flanks of the basins, the processes affecting sedimentation in the basin floors, and to compare the deeper structures and surficial processes between the basins.  The second study area focused on three salt domes, the processes associated with them, and how they affect the shallow subsurface stratigraphy. Initial observations suggest that most of the surface and shallow subsurface geohazards are associated with the flanks of salt structures. Here active salt movement generates faults along which hydrocarbons can escape to the seafloor, and tectonic oversteepenning generates slope failures.

Extent of Corcoran Clay modified from Page (1986) for the Central Valley Hydrologic Model (CVHM)

This digital dataset defines the areal extent of the Corcoran Clay Member of the Tulare Formation. 
The complex hydrologic system of the Central Valley is simulated using the USGS numerical 
modeling code MODFLOW-FMP (Schmid and others, 2006b).  This simulation is referred to 
here as the Central Valley Hydrologic Model (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.  Numerous 
lenses of fine-grained sediments are distributed throughout the southern Central Valley (San 
Joaquin Valley) and generally constitute more than 50 percent of the total thickness of the valley 
fill. Generally, these lenses are discontinuous and not vertically extensive or laterally continuous. 
However, the Corcoran Clay is a low-permeability, a really extensive, lacustrine deposit (Johnson 
and others, 1968) as much as 200-ft thick (Davis and others, 1959; Page, 1986). This continuous 
clay divides the groundwater-flow system of the western San Joaquin Valley into an upper semi-
confined zone and a lower confined zone (Williamson and others, 1989; Belitz and Heimes, 1990; 
Burow and others, 2004).  The extent and distribution of the Corcoran Clay was defined for use in 
the CVHM because the unit is one of the few deposits in the Valley that can be regionally mapped. 
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).

This map layer contains the shallowest principal aquifers of the
conterminous United States, Hawaii, Puerto Rico, and the U.S. Virgin
Islands, portrayed as polygons.  The map layer was developed as part of
the effort to produce the maps published at 1:2,500,000 in the printed
series "Ground Water Atlas of the United States".  The published maps
contain base and cultural features not included in these data.  This is a
replacement for the July 1998 map layer called Principal Aquifers of the

GAK_Q33.TIF - Gulf of Alaska U.S. EEZ GLORIA sidescan-sonar data mosaic (3 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.

Grayscale GeoTIFF Image of the 1-m Sidescan-Sonar Data From National Oceanic and Atmospheric Administration (NOAA) Survey H12023 in Block Island Sound (H12023_1MSSS_UTM19.TIF, UTM Zone 19, NAD83)

The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is producing detailed geologic maps of the coastal sea floor. Bathymetric and sidescan-sonar data, originally collected by NOAA for charting purposes, provide a fundamental framework for research and management activities along this part of Block Island Sound, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. During June 2012, bottom photographs and surficial sediment data were acquired as part of a ground-truth reconnaissance survey of this area. Interpretations were derived from the multibeam-echosounder, sidescan-sonar, sedimentary, and photographic data collected in Block Island Sound. For more information on the ground-truth survey see &lt;http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2012-002-FA&gt;.

Extratropical Storm March 2018 Assessment of Potential Coastal Change Impacts: 0800 AM EST FRI MAR 02 2018

This dataset defines storm-induced coastal erosion hazards for the North Carolina, Virginia, Maryland, Delaware, New Jersey, New York, Rhode Island, Massachusetts, New Hampshire and Maine coastline. The analysis was based on a storm-impact scaling model that used observations of beach morphology combined with sophisticated hydrodynamic models to predict how the coast would respond to the direct landfall of an Extratropical Storm in March 2018. Storm-induced water levels, due to both surge and waves, were compared to beach and dune elevations to determine the probabilities of the three types of coastal change: collision (dune erosion), overwash, and inundation. All hydrodynamic and morphologic variables are included in this dataset.
