Point shapefile of processed continuous resistivity profiling data below the sediment water interface collected in the Indian River Bay, Delaware, on April 14, 2010, on U.S. Geological Survey Field Activity 2010-006-FA (MRGAPR14_ALLXYZRES.SHP, Geographic, WGS 84)

A geophysical survey to delineate the fresh-saline groundwater interface and associated sub-bottom sedimentary structures beneath Indian River Bay, Delaware, was carried out in April 2010. This included surveying at higher spatial resolution in the vicinity of a study site at Holts Landing, where intensive onshore and offshore studies were subsequently completed. The total length of continuous resistivity profiling (CRP) survey lines was 145 kilometers (km), with 36 km of chirp seismic lines surveyed around the perimeter of the bay. Medium-resolution CRP surveying was performed using a 50-meter streamer in a bay-wide grid. Results of the surveying and data inversion showed the presence of many buried paleochannels beneath Indian River Bay that generally extended perpendicular from the shoreline in areas of modern tributaries, tidal creeks, and marshes. An especially wide and deep paleochannel system was imaged in the southeastern part of the bay near White Creek. Many paleochannels also had high-resistivity anomalies corresponding to low-salinity groundwater plumes associated with them, likely due to the presence of fine-grained estuarine mud and peats in the channel fills that act as submarine confining units. Where present, these units allow plumes of low-salinity groundwater that was recharged onshore to move beyond the shoreline, creating a complex fresh-saline groundwater interface in the subsurface. The properties of this interface are important considerations in construction of accurate coastal groundwater flow models. These models are required to help predict how nutrient-rich groundwater, recharged in agricultural watersheds such as this one, makes its way into coastal bays and impacts surface water quality and estuarine ecosystems.

MODFLOW-NWT groundwater flow model used to evaluate conditions in the Northern High Plains Aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming: U.S. Geological Survey data release

A three-dimensional groundwater flow model was developed to characterize groundwater resources and the 
interaction of groundwater with streams and other hydrologic features in the Northern High Plains aquifer. 
The Northern High Plains aquifer is generally unconfined; most of the water withdrawn from the aquifer is 
used for irrigation. A modified version of a previously published soil-water-balance (SWB) model estimates 
recharge using climatic, soils, land cover data, in addition to data for groundwater withdrawals for irrigation. 
The SWB output was adjusted in areas where surface water is used for irrigation. The groundwater flow model 
results were calibrated using parameter estimation to measured groundwater levels and estimated stream base 
flows. The model was designed as a tool for regional evaluations of groundwater resources and of groundwater 
interactions with streams and other hydrologic features resulting from current or forecasted conditions. This 
USGS data release contains all of the input and output files for the model described in the associated model 
documentation report (https://doi.org/10.3133/sir20165153). This data release also includes 
(1) MODFLOW-NWT (version 1.0.9) source code, and (2) SWB source code in two formats.

Grids of Agricultural Pesticide Use in the Conterminous United States, 1997

This spatial dataset consists of 219 1-kilometer (km) resolution
grids depicting estimated agricultural use of 219 pesticides in 1997
for the conterminous United States. Each grid cell value in the
national grids of this dataset is the estimated total kilograms (kg) of
a pesticide applied to row crops, small grain crops and fallow land,
pasture and hay crops, and orchard and vineyard crops within the
1- by 1-km area. Nonagricultural uses of pesticides are not included
in this dataset. Of the 219 pesticidesrepresented in the grids, 96
are herbicides, 65 are insecticides, and 37 are fungicides. The
remaining 21 compounds are composed of the category "other pesticides",
which consist of fumigants, growth regulators, and defoliants.
Although this dataset is referenced to 1997, it generally represents
a composite of estimated pesticide use during the mid to late 1990s.

LANDFIRE Remap Anderson Fire Behavior Fuel Model (FBFM13) Palau

LANDFIRE’s (LF) 2016 Remap (Remap) Anderson Fire Behavior Fuel Model 13 (FBFM13) product represents distinct distributions of fuel loadings found among surface fuel components (live and dead), size classes, and fuel types (Anderson 1982). The fuel models are described by the most common fire carrying fuel type (grass, brush, timber, or slash), loading and surface area-to-volume ratio by size class and component, fuel bed depth, and moisture of extinction. FBFM13 can be used for fire spread related characteristic models. 
LF Remap used vegetation products and 10-years of disturbance data to create Fuel Vegetation Type (FVT), Fuel Vegetation Cover (FVC), and Fuel Vegetation Height (FVH) for disturbed areas to represent pre-disturbance scenarios in FBFM13. A combination of pre-disturbance and non-disturbance Existing Vegetation Type (EVT) are used to assign surface fuel models. FBFM13 was developed using the most recent 10 years of Annual Disturbance products and is a capable fuels product that calculates Time Since Disturbance (TSD) assignments for disturbed areas using an "effective year." For example, year 2020 fuels may be calculated for the year 2020. the new process considers all the existing disturbances included in LF Remap and adjusts the TSD for these to the effective year (2020 in the example), making the products "2020 capable fuels." More information about capable fuels can be found at https://www.landfire.gov/lf_remap.php.

Irrigation Land Leveling on Agricultural Land in the Conterminous United States, 1992: National Resource Inventory Conservation Practice 464

This data set represents the estimated percentage of the 1-km grid cell that is covered by or subject to the 
agricultural conservation practice (CP464), Irrigation Land Leveling (ILL) on agricultural land by county.  
Irrigation Land Leveling is described as "[r]eshaping the surface of land to be irrigated to planned grades.
for the purpose of permitting uniform and efficient application of irrigation water to the leveled land." 
(U.S. Department of Agriculture, 1995)  This data set was created with geographic information systems 
(GIS) and database management tools. The acres on which ILL's are applied were totaled at the county 
level in the tabular NRI database and then apportioned to a raster coverage of agricultural land within the 
county based on the Enhanced National Land Cover Dataset (NLCDe) 1-kilometer resolution land cover 
grids (Nakagaki, 2003). Federal land is not considered in this analysis because NRI does not record 
information on those lands.

BITH2014_LowerNechesRiverCorridorUnit_EAARLB_BE_z15_n88g12A_mosaic_metadata: EAARL-B Topography-Big Thicket National Preserve: Lower Neches River Corridor Unit, Texas, 2014

A bare-earth topography Digital Elevation Model (DEM) mosaic for the Lower Neches River Corridor Unit of Big Thicket National Preserve in Texas was produced from remotely sensed, geographically referenced elevation measurements collected on January 11, 15, 17, 18, 19, 21, 23, 25, 27, and 29, 2014 by the U.S. Geological Survey, in cooperation with the National Park Service - Gulf Coast Network. Elevation measurements were collected over the area using the second-generation Experimental Advanced Airborne Research Lidar (EAARL-B), a pulsed laser ranging system mounted onboard an aircraft to measure ground elevation, vegetation canopy, and coastal topography. The system uses high-frequency laser beams directed at the Earth's surface through an opening in the bottom of the aircraft's fuselage. The laser system records the time difference between emission of the laser beam and the reception of the reflected laser signal in the aircraft. The plane travels over the target area at approximately 55 meters per second at an elevation of approximately 300 meters, resulting in a laser swath of approximately 240 meters with an average point density of 1.4 points per square meter. A peak sampling rate of 15-30 kilohertz results in an extremely dense spatial elevation dataset. More than 100 kilometers of coastline can be surveyed easily within a 3- to 4-hour mission. When resultant elevation maps for an area are analyzed, they provide a useful tool to make management decisions regarding land development.

2009 North Carolina USACE Lidar-Derived Dune Crest, Toe and Shoreline

The Storm-Induced Coastal Change Hazards component of the National Assessment of Coastal Change Hazards project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. Lidar-derived beach morphologic features such as dune crest, toe and shoreline help define the vulnerability of the beach to storm impacts. This dataset defines the elevation and position of the seaward-most dune crest and toe and the mean high water shoreline derived from the 2009 U.S. Army Corps of Engineers (USACE) North Carolina lidar survey. Beach width is included and is defined as the distance between the dune toe and shoreline along a cross-shore profile. The beach slope is calculated using this beach width and the elevation of the shoreline and dune toe.

PACIFIC - Coastal Vulnerability to Sea-Level Rise: U.S. Pacific Coast

The goal of this project is to quantify, at the National scale, the relative susceptibility of the Nation's coast to sea-level rise through the use of a coastal vulnerability index (CVI). This initial classification is based upon the variables geomorphology, regional coastal slope, tide range, wave height, relative sea-level rise and shoreline erosion and accretion rates. The combination of these variables and the association of these variables to each other furnish a broad overview of regions where physical changes are likely to occur due to sea-level rise.

Laboratory Observations of Artificial Sand and Oil Agglomerates: Video and Velocity Data: Sea Floor Interaction Experiment Preview Video (GoPro)

Weathered oil in the surf-zone after an oil spill may mix with suspended sediments to form sand and oil agglomerates (SOA). Sand and oil agglomerates may form in mats on the scale of tens of meters (m), and may break apart into pieces between 1 and 10 centimeters (cm) in diameter. These more mobile pieces are susceptible to alongshore and cross-shore transport, and lead to beach re-oiling on the time scale of months to years following a spill. The U.S. Geological Survey (USGS) conducted experiments March 10 - 13, 2014, to expand the available data on sand and oil agglomerate motion; test shear stress based incipient motion parameterizations in a controlled, laboratory setting; and directly observe SOA exhumation and burial processes.  Artificial sand and oil agglomerates  (aSOA) were created and deployed in a small-oscillatory flow tunnel in two sets of experiments, during which, video and velocity data were obtained. The first experiment, which was set up to help researchers investigate incipient motion, used with an immobile, rough bottom (referred to as false-floor) and the second–testing seafloor interactions–utilized with a coarse grain sand bottom (movable sand bed). Detailed information regarding the creation of the aSOA can be found in Dalyander et al. (2015).  More information about the USGS laboratory experiment conducted in collaboration with the Naval Research Laboratory can be found in the associated Open File Report (OFR Number Unknown).

Sediment Grain-size Data from sediment core samples collected in March/April 2014 from Assateague Island and the mainland of Virginia and Maryland (U.S. Geological Survey Field Activity Numbers 2014-301-FA, and 2014-322-FA).

The influence of tropical and extratropical cyclones on coastal wetlands and marshes is highly variable in both space and time and depends on a number of climatic, geologic, and physical variables.  The impacts storms can be either positive or negative with respect to the wetland and marsh ecosystems. Small to moderate amounts of inorganic sediment added during storms or other events helps to abate pressure from sea-level rise.  However, if the volume of sediment is large and the resulting deposits thick, the organic substrate may compact causing submergence and a loss in elevation.  Similarly, thick deposits of coarse inorganic sediment may also alter the hydrology of the site and impede vegetative processes.  Alternative impacts associated with storms include shoreline erosion at the marsh edge as well as potential emergence.  Predicting the outcome of these various responses and potential long-term implications can be obtained from a systematic assessment of both historical and recent event deposits.  The objectives of this study are to 1) characterize the surficial sediment of the relict to recent washover fans and back-barrier marshes, and 2) characterize the sediment of 6 marsh cores from the back-barrier marshes and a single marsh island core near the mainland.  These geologic data will be integrated with other remote sensing data collected along Assateague Island, Maryland / Virginia and assimilated into an assessment of coastal wetland response to storms.
