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

Median of wave-current bottom shear stress in the Middle Atlantic Bight for May, 2010 - May, 2011 (MAB_median.SHP)

The U.S. Geological Survey has been characterizing the regional variation in shear stress on the sea floor and sediment mobility through statistical descriptors.  The purpose of this project is to identify patterns in stress in order to inform habitat delineation or decisions for anthropogenic use of the continental shelf.  The statistical characterization spans the continental shelf from the coast to approximately 120 m water depth, at approximately 5 km resolution.  Time-series of wave and circulation are created using numerical models, and near-bottom output of steady and oscillatory velocities and an estimate of bottom roughness are used to calculate a time-series of bottom shear stress at 1-hour intervals.  Statistical descriptions such as the median and 95th percentile, which are the output included with this database, are then calculated to create a two-dimensional picture of the regional patterns in shear stress.  In addition, time-series of stress are compared to critical stress values at select points calculated from observed surface sediment texture data to determine estimates of sea floor mobility.

STATSGO soil characteristics for the conterminous United States

This digital data release consists of an ARC/INFO grid and associated
INFO tables. The grid is called MUID and has STATSGO (U.S. Department
of Agriculture, 1994) soil mapping unit identifiers gridded on a
1-kilometer resolution for the conterminous United States. The INFO
tables have soil characteristics data in them. The ITEMS in the tables
are weighted average values for several soil characteristics in the
STATSGO data base. The weighted average values were computed by
aggregating the soil layers and components in the data base.
		
The INFO tables are called MUID.LAYER, MUID.COMP, MUID.KFACT,
MUID.TFACT, and MUID.WEG. The INFO tables can be related or joined to
the MUID grid or to individual State coverages (grids or polygons) of
MUIDs. Joining or relating the tables to the MUID grid creates
1-kilometer resolution grids of the soil characteristics for the
conterminous United States.
		
The soil characteristics in MUID.LAYER are permeability (PERML and
PERMH in the STATSGO data base), available water capacity (AWCL and
AWCH), bulk density (BDL and BDH), and organic matter (OML and
OMH). The soil characteristics in MUID.COMP are slope (SLOPEL and
SLOPEH), depth to seasonally high water table (WTDEPL and WTDEPH), and
depth to bedrock (ROCKDEPL and ROCKDEPH). The soil characteristic in
MUID.KFACT is the soil erodibility factor (KFACT), the soil
characteristic in MUID.TFACT is the soil loss tolerance factor
(TFACT), and the soil characteristic in MUID.WEG is the wind erosion
group (WEG).
		
The MUID grid and INFO tables were created with a set of arc macro
language (aml) and Fortran programs. Send electronic mail to
dwolock@usgs.gov to obtain copies of the computer code. (See

Potential marine benthic habitat maps were constructed using multibeam echosounder (MBES) bathymetry and backscatter data. The habitats were based on substrate types and documented or "ground truthed" using underwater video images and seafloor samples obtained by the USGS. These maps display various habitat types that range from flat, soft, unconsolidated sediment-covered seafloor to hard, deformed (folded), or highly rugose and differentially eroded bedrock exposures.

NORCAL_BIASVALUES - Northern California Shoreline Bias Values

The USGS has produced a comprehensive database of digital vector shorelines by compiling shoreline positions from pre-existing historical shoreline databases and by generating historical and modern shoreline data.  Shorelines are compiled by state and generally correspond to one of four time periods: 1800s, 1920s-1930s, 1970s, and 1998-2002.  These shorelines were used to calculate long-term and short-term change rates in a GIS using the Digital Shoreline Analysis System (DSAS) version 3.0; An ArcGIS extension for calculating shoreline change: U.S. Geological Survey Open-File Report 2005-1304, Thieler, E.R., Himmelstoss, E.A., Zichichi, J.L., and Miller, T.M. Shoreline vectors derived from historic sources (first three time periods) represent the high water line (HWL) at the time of the survey, whereas modern shorelines (final time period) represent the mean high water line (MHW). Changing the shoreline definition from a proxy-based physical feature that is uncontrolled in terms of an elevation datum (HWL) to a datum-based shoreline defined by an elevation contour (MHW) has important implications with regard to inferred changes in shoreline position and calculated rates of change. This proxy-datum offset is particularly important when averaging shoreline change rates alongshore. Since the proxy-datum offset is a bias, virtually always acting in the same direction, the error associated with the apparent shoreline change rate shift does not cancel during averaging and it is important to quantify the bias in order to account for the rate shift. The shoreline change rates presented in this report have been calculated by accounting for the proxy-datum bias.

Processed Continuous Resistivity Profiles Collected in the Neuse River, May 4, 2005

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.

Sea Turtle Nesting Decision Points and Cross-Shore Beach Profile Data Collected on May 21, 2021, from Juno Beach, Florida

On May 21, 2021, surveys were conducted on ‘high-density’ sea turtle nesting areas located on Juno Beach, Florida.

Utilizing previously published methods for collecting beach profile data (Henderson and others, 2016; Brown and others, 2018), data were acquired by USGS scientists walking along cross-shore transect lines while carrying a survey backpack that was equipped with a Global Navigation Satellite System (GNSS) receiver and GNSS antenna. The horizontal position data are provided in the Universal Transverse Mercator (UTM) coordinate system, Zone 17 North (17N), referenced to the North American Datum of 1983 (NAD83), and the elevation data are referenced to the North American Vertical Datum of 1988 (NAVD88), GEOID12B.
