Data

This data release includes metadata and tabular data that document Acacia koa density, basal area, and grass cover before and after the 2018 Keauhou Ranch Fire in Hawaii Volcanoes National Park. Specifically, we asked three questions: 1) At what level of precision can pre-fire grass cover be accurately estimated from oblique aerial photos? 2) How are post-fire Acacia koa regeneration densities aff

Fog has been demonstrated to support plant growth, survival and ecosystem maintenance spanning rainfall and elevation gradients across the world. Persistent fog and strong winds on high mountain slopes in Hawai'i create a unique ecological environment. We collected stem diameter measurements of three native plant species at Nakula Natural Area Reserve, Maui, during 2016-2019 and numerous environme

This metadata document describes the data contained in the "processedData" folder of this data package. This data package contains all data collected by the Argos System from 217 satellite transmitters attached to Spectacled Eiders on their breeding range in arctic and western Alaska and northeastern Russia, 1993-2011. The raw data were processed to accomplish two goals: flag implausible location

The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center in Sioux Falls, SD developed a cloud validation dataset from 48 unique Landsat 8 Collection 2 images. These images were selected at random from the Landsat 8 archive from various locations around the world. While these validation images were subjectively designed by a single analyst, they provide useful informa

Silver nanoparticles (AgNP) are one type of contaminant that can enter treatment wetlands (Wiesner 2006) and impact the overall treatment efficacy. Grazing by filter feeding zooplankton, such as Daphnia magna, is critical to treatment wetland functioning (Ismail 2019), but the effects of AgNP on zooplankton are not fully understood, especially at environmentally relevant concentrations. In this st

This data release presents projected flooding extent polygon (flood masks) shapefiles based on wave-driven total water levels for the State Florida (the Florida Peninsula and the Florida Keys). There are 12 associated flood mask shapefiles: one for each of four nearshore wave energy return periods (rp; 10-, 50-, 100-, and 500-years), the current scenario (base) and each of the degradation scenario

This data release provides flooding extent polygons based on wave-driven total water levels for the coral lined coast of Florida and the Commonwealth of Puerto Rico. The wave and sea-level conditions were then propagated using the XBeach over 100-m spaced shore-normal transects modified to account for base and post-storm scenarios. In situ observations following hurricanes Irma and Maria were used

This data release provides flooding extent polygons based on wave-driven total water levels for the coral lined coasts of Florida, Puerto Rico, and the U.S. Virgin Islands. The locations of the restoration lines along and across shore were defined by the presence of continuous coral/hardbottom habitat of greater than 100 m alongshore length and proximity to the 3-m depth contour. The wave and sea

A machine learning streamflow (MLFLOW) model was developed in R (model is in the Rscripts folder) for modeling monthly streamflow from 2012 to 2017 in three watersheds on the Wyoming Range in the upper Green River basin. Geospatial information for 125 site features (vector data are in the Sites.shp file) and discrete streamflow observation data and environmental predictor data were used in fitting

The USGS Coral Reef Ecosystems Studies project provides science that helps resource managers tasked with the stewardship of coral reef resources. This data release contains data on coral-growth rates and time-series photographs taken of colonies of the mustard hill coral, Porites astreoides, grown at four sites on the Florida Keys reef tract from spring 2015 to spring 2017. The data will be used t

Holocene-aged corals from reef cores collected throughout the Florida Keys reef tract (FKRT; Fig. 1) were dated using a combination of U-series and radiocarbon techniques to quantify the millennial-scale variability in the local radiocarbon reservoir age (delta-R) of the shallow water environments of south Florida. delta-R provides a measure of the deviation of local radiocarbon concentrations of

The data comprise an archive of repeated surveyed measurements to monitor surface fault creep (a form of gradual tectonic movement) occurring along active faults in the San Francisco Bay region for use by the scientific research community. Additional description of these data and the methods used to collect them is provided at: https://pubs.usgs.gov/of/2009/1119/. The primary data are angle measur
