Methane, carbon dioxide and water vapor fluxes from a Louisiana tidal saltwater marsh, 2023

Wind speed, wind direction (3D) and gas concentrations are measured at 10 Hz and statistically processed using the eddy covariance technique to half-hour estimates of flux rates of gas exchange between the ecosystem and atmosphere. Three gases were measured: carbon dioxide, methane and water vapor. Simultaneous measurements of environmental drivers are also measured and recorded as half-hourly values: photosynthetic photon flux density, downwelling and upwelling short and long wave radiation, air temperature, relative humidity and precipitation. Variable names and units follow AmeriFlux and FLUXNET standards. This site is a saltwater herbaceous marsh near Lake Hermitage, LA and Barataria Bay.

Chirp Seismic Survey Tracklines - Lake Mohave 2002

Lake Mohave is one of several multi-purpose reservoirs that have been constructed on the Colorado River.  The lake was formed upon completion of the Davis Dam in 1953. No mapping of the floor of the lake had been conducted since completion of the Davis Dam. The U.S. Geological Survey, in cooperation with researchers from the University of Nevada Las Vegas, completed a geophysical survey of this lake in April 2002.  The survey included collection of sidescan sonar imagery of nearly the entire lake floor, and high-resolution seismic-reflection profiles along widely spaced lines throughout the lake.  The detailed mapping of the lake floor was used to determine the amount of sediment that had accumulated in the lake since impoundment, its distribution, and the processes of deposition.

SEG-Y format of boomer seismic-reflection profiles collected in the Pulley Ridge study area 2001

These seismic data were collected to infer the paleodepositional environment of Pulley Ridge through seismic facies analysis.  Without actual rock cores, remote sensing is the next best tool.  It was uncertain if Pulley Ridge represented a drowned reef or paleoshoreline.  Through seismic imaging, it was determined from the high-amplitude, level-bedded nature of material in the sub-surface that Pulley Ridge represents several stages of barrier-island development.

Sally_R0_elevation: Modeling the impacts of sand placement strategies on barrier island evolution in a semi-enclosed bay system: model input and results

Using version 5527 of the XBeach numerical model (Roelvink and others, 2009), barrier island morphological change was simulated at Little Dauphin Island, Alabama (AL) under different storm scenarios and restoration alternatives as described in Passeri and others (2025). The two-dimensional XBeach model can be applied to barrier islands to solve for time-dependent elevations (topography and bathymetry). The XBeach model setup requires the input of topographic and bathymetric elevations at each grid cell. Model inputs and outputs in the form of elevation at each grid cell are provided in this data release. For further information regarding model input generation and visualization of model output, refer to Passeri and others (2025).

LANDFIRE Remap Forest Canopy Bulk Density (CBD) CONUS

LANDFIRE's (LF) Remap Canopy Bulk Density (CBD) describes the mass of available canopy fuel per unit canopy volume that would burn in a crown fire. A spatially explicit map of CBD supplies information used in fire behavior models to determine the spread characteristics of crown fires across the landscape. The CBD mapping process derives field referenced estimates of canopy characteristics through LF Reference Database (LFRDB) plot analysis. Utilizing the LFRDB plots, field referenced CBD values are computed for each plot with the canopy fuel estimation software FuelCalc. In FuelCalc, for tree species that have no crown biomass, an equation for a species with a similar genus is used as a substitute. Species widely considered to be resistant to fire are excluded, for example, Acer and Populus spp. are excluded from the canopy fuel profile because these species are considered relatively inflammable and therefore unavailable. 
CBD has a series of post processing techniques and logic checks ensuring it is relevant in the context of other fuel products and fire behavior predictions. All non-forest values and non-burnable types such as urban, barren, snow and ice, and agriculture are coded as 0. Some stands dominated by broadleaf species which typically do not permit initiation of crown fire (e.g. Populus spp.) are coded with a CBD of 0.01 kg m-3.  In some instances, LF Remap assumes the potential burnable biomass in the tree canopy has been accounted for in the surface fuel model. For example, young or short conifer stands where the trees are represented by a shrub type fuel model will not have canopy characteristics. 
LF Remap Annual Disturbance products are incorporated into CBD to provide informed changes by disturbance type, severity, and time since disturbance (TSD). Annual Disturbance products provide a pre-disturbance scenario represented by LF Remap existing vegetation products. Reporting of the pre-disturbance scenario helps to calculate CBD, with information about vegetation type, cover, and height impacted by a disturbance. With the use of Annual Disturbance products, CBD also has capable fuels functionality. Capable fuels calculate TSD assignments for disturbed areas using an effective year. For example, year 2019 fuels may be calculated for the year 2019. This new process considers all the existing disturbances included in LF Remap and adjusts the TSD for these to the effective year (2019 in this example), making the products "2019 capable fuels." More information about capable fuels can be found at https://www.landfire.gov/lf_remap.php.

2012 Post-Hurricane Sandy Northeast Atlantic Coast USGS Lidar-Derived Dune Crest, Toe and Shoreline

The Storm-Induced Coastal Change Hazards component of the 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 2012 Post-Hurricane Sandy Northeast Atlantic (North Carolina to Delaware) USGS 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.

Sediments of Western Mass Bay acquired in 1976 (MEISBURGER76 shapefile)

A seismic reflection survey with concurrent bottom sampling was conducted in western Massachusetts Bay to obtain information on bottom topography and sediments, subbottom structure and composition, and the location of sand deposits potentially usable for restoration and nourishment of nearby beaches.  Primary sediment data was derived from 43 cores.  The predominant sediments of the surface and shallow subsurface deposits in the study area are fine sand, sand and gravel, and clayey silt.  Sand suitable for beach restoration and nourishment on the contiguous coast occurs only locally and in generally small quantity relative to other sediments of the study area.
