An Unvegetated to Vegetated Ratio (UVVR) for coastal wetlands of the Pacific Coast - 1999

Prior research has shown that sediment budgets, and therefore stability, of microtidal marsh complexes scale with areal unvegetated to vegetated marsh ratios (UVVR) suggesting these metrics are broadly applicable indicators of microtidal marsh vulnerability. This effort has developed the UVVR metric using readily available satellite imagery for the coastal areas of the contiguous United States (CONUS). These datasets provide annual averages of the 1) unvegetated fraction, 2) vegetated fraction, 3) water fraction and 4) an unvegetated to vegetated ratio (UVVR) at 30-meter resolution over the coastal areas of the contiguous United States for the year 1999. Additionally, multi-year average values of vegetated ratio, its standard deviation and a UVVR based on the annually-averaged vegetated ratio are provided for the coastal wetlands of the contiguous United States.

Wetland Paleoecological Study of Coastal Louisiana: Sediment Cores and Diatom Samples Dataset

Wetland sediment data was collected from coastal Louisiana as part of a pilot study to develop a diatom-based proxy for past wetland water chemistry and the identification of sediment deposits for tropical storms. The complete dataset includes forty-six surface sediment samples and nine sediment cores. The surface sediment samples were collected in fresh to brackish marsh throughout the southwest Louisiana Chenier Plain and are located coincident with Coastwide Reference Monitoring System (CRMS). Sediment cores were collected at Rockefeller Wildlife Refuge. The data described here include sedimentary properties, radioisotopes, x-radiographs, and diatom species counts for depth-interval samples of sediment cores.

Enhanced National Land Cover Data 1992 revised with 1990 and 2000 population data to indicate urban development between 1992 and 2000 (NLCDep0306)

This 30-meter resolution raster data set of land cover for the
conterminous United States ("NLCDep0306") was designed to
describe conditions representative of the year 2000 and is the
result of overlaying enhanced 1992 National Land Cover Data with
1990 and 2000 population data at the block group geographic
level. Any area (excluding water, developed land, or wetlands)
with population density of less than 1,000 people per square
mile in 1990 and at least 1,000 people per square mile in 2000
was reclassified as "newly urbanized" land in the derivative
product.  Areas of water, developed land, or wetlands existing
in the original national land-cover data set were preserved.
		
This data set supersedes the one called "Enhanced National Land
Cover Data 1992 revised with 2000 population data to indicate
urban development between 1992 and 2000" ("NLCDep0905") dated
September 2005. NLCDep0905 coded any area having 2000 population
density of at least 1,000 people per square mile as being
recently urbanized and did not consider that the area could
already have been urbanized in 1990. The approach used in
developing NLCDep0905 was determined to have misclassified lands
that already were urban in 1990 as newly urbanized and therefore
overrepresented new urban land.

Age-0 Sablefish Size and Growth Indices from Seabird Diets at Middleton Island, Alaska

This dataset provides annual summaries of information on age-0 sablefish in Rhinoceros Auklet (Cerorhinca monocerata) chick diets from Middleton Island, Alaska. This includes number of diet samples, number of sablefish sampled, proportion of total biomass, catch per unit effort, and frequency of occurrence for each year.
      We calculated an annual growth index for age-0 sablefish using the relationship between mean length by day and Julian day for each year (OLS[F = 24.44, df = 61, 184]: R^2 = 0.85, p &lt; 0.001). From this model, growth (in mm per day) is the slope, and predicted length (in mm) is the length on the median Julian day = 205 (July 24). Annual anomalies of growth and length are calculated for each variable by subtracting the mean of all years.

Fuel break treatments in the sagebrush biome of the western United States, 1953 - 2018

To better inform fuel break planning and assessment, we developed a comprehensive spatial database of known existing fuel breaks from 1953 to 2018 throughout the western United States. Each fuel break is represented as a polygon in the database and is attributed with the date of installation, the treatment type employed, and the data source. The availability of these data promotes the development of a monitoring framework to track the maintenance and longevity of different treatment types, as well as record the use, conditions, and outcomes of suppression activities at specific fuel break locations. The data also facilitate the quantification of important temporally varying qualities that may influence suppression, such as vegetation composition and precipitation conditions that mediate fuels. This information may help wildfire crews and fuels program managers prioritize which fuel breaks to maintain and use. Additionally, these data can contribute to studies of ecological impacts of fuel breaks on sagebrush ecosystems, such as their potential contribution to annual grass invasion, effects on sensitive species and their habitat, and potential use as corridors for predators. Results from these analyses can help inform the placement of future fuel breaks to increase their use and effectiveness for imperative fire operations while minimizing negative ecological impacts in sensitive and threatened ecosystems.

Potmap_wells_May_June2010

Water-level measurements of wells were taken in the Upper Floridan aquifer between the dates of May 2 and June 23, 2010. A GIS shapefile of these water-level measurements was constructed and released as part of a prior USGS publication (Kinnaman and Dixon, 2011). This ArcGIS layer was updated in August 2014 to include salinity-based density corrections to water levels in those areas of south Florida where water in the subject aquifer is not fresh. The density corrections to water levels result in the portrayal of the “equivalent freshwater head” values in brackish and saline areas of the Upper Floridan aquifer where water quality data were available.

Coastwide Reference Monitoring System (CRMS) 2021 Site 0220 land-water classification data

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring efforts to determine the efficacy of these efforts. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 398 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Digital Orthophoto Quarter Quadrangles (DOQQs) approximately every three years at all CRMS sites. A DOQQ is a raster image in which displacement in the image caused by sensor orientation and terrain relief has been removed and combines the image characteristics of a photo with geometric qualities of a map. The DOQQs generated for this project consist of 2021 Color Infrared (CIR) Digital Imagery. These images were classified into land and water categories using a threshold of the near infrared (NIR) band, followed by supervised and unsupervised classification.  Initial classification results are then reviewed by multiple image analysts to identify and manually recode errors. The final land-water classifications are intended to serve as both geographic and quantitative assessments of landscape composition on the date of acquisition. Five previous assessments have been conducted (2005, 2008, 2012, 2015/2016, and 2018). Once the program creates enough data points for statistical analyses, these data will be used for land area change rate calculation.

Supplemental Results from: Using mobile acoustic monitoring and false-positive N-mixture models to estimate bat abundance and population trends

These data contain the supplementary results corresponding with the journal article: Using mobile acoustic monitoring and false-positive N-mixture models to estimate bat abundance and population trends by Udell et al. (2024) in Ecological Monographs. These results contain the findings from the North American Bat Monitoring Program's (NABat) "Summer Abundance Status and Trends" analyses which used mobile transect acoustic data for three species (tricolored bat, little brown bat, and big brown bat). Data from the entire summer season (May 1–Aug 31) were used in the modeling process. Here, tabular data for each species include predictions (with uncertainty) of relative abundance (and trends over time) in the summer maternity season (May1 - July 16) from 2012-2020. Predictions for status and trends are provided for each species at four different spatial resolutions: 1) across the modeled species ranges, 2) at the state or province level, 3) at the NABat grid cell (10km x 10km scale) level, and 4) for each sampled transect. Predictions were produced using an analytical pipeline supported by web-based infrastructure, Bayesian hierarchical modeling, and 'false-positive N-mixture model' framework which analyzed mobile transect acoustics to model the relative abundance distribution (and trends over time) of each species while accounting for imperfect detection and species misclassification. 
Tabular files provided include: 1) range-wide average relative abundance predictions by year for each species, 2) range-wide trends in average relative abundance for each species, 3) regional (state/province) average relative abundance by year for each species, 4) regional (state/province) trends in average relative abundance for each species, 5) grid cell-level predictions of relative abundance by year for each species, 6) grid cell-level trends (overall change from 2012-2020) for each species (one file per species), and 7) transect-level estimates of relative abundance by year for each species. Estimates include means, medians, standard deviations, and the 95% Bayesian credible intervals. These data can be cross-referenced to the 'knitted' NABat master sample for CONUS, Canada, and Alaska (NABat_grid_covariates.shp, which is available on ScienceBase).

2010 Southeast Atlantic 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 2010 Southeast Atlantic (Florida to North Carolina) U.S. Army Corps of Engineers (USACE) 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.

LANDFIRE Remap Fuel Vegetation Type (FVT) HI

The LANDFIRE (LF) Remap Fuel Vegetation Type (FVT) represents a modified pre-disturbance version of Existing Vegetation Type (EVT). FVT leverages fuel transition assignments related to disturbed areas by re-establishing pre-disturbance vegetation. FVT was developed using the full suite of LF vegetation releases and 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. This new process considers all the existing disturbances included in LF Remap and adjusts the TSD for these to the effective year (2020 in this example), making the products "2020 capable fuels." More information about capable fuels can be found at https://www.landfire.gov/lf_remap.php. The FVT product is then evaluated through a series of QA/QC measures ensuring lifeform of the vegetation type assignment matches the lifeform of associated FVT attributes.
