Data

The U.S. Geological Survey St. Petersburg Coastal and Marine Science Center developed the Along-Track Reef Imaging System (ATRIS) in order to capture high-resolution, geo-located images of the seafloor. The images in this data release were collected September 29-30, 2011 at West Turtle Shoal, Rawa, Dustan Rocks, and Thor patch reefs near Marathon, Florida. The transects below show the path of imag

Two dams on the Elwha River, Washington State, USA trapped over 20 million cubic meters of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system

This dataset displays the spatial variation mean tidal range (i.e. Mean Range of Tides, MN) in the Edwin B. Forsythe National Wildlife Refuge (EBFNWR), which spans over Great Bay, Little Egg Harbor, and Barnegat Bay in New Jersey, USA. MN was calculated as the difference in height between mean high water (MHW) and mean low water (MLW) using the VDatum (v3.5) software (http://vdatum.noaa.gov/). The

This dataset is the largest global dataset to date of soil respiration, moisture, and temperature measurements, totaling >3800 observations representing 27 temperature manipulation studies, spanning nine biomes and nearly two decades of warming experiments. Data for this study were obtained from a combination of unpublished data and published literature values. We find that although warming increa

Lidar-derived bare-earth topography Digital Elevation Model (DEM) mosaic and classified point-cloud datasets were produced from remotely sensed, geographically referenced elevation measurements collected post-Hurricane Irene on August 30, 2011 for Long Island, New York, using a Leica ALS50-II.

Understanding the processes that govern whether a coral reef is accreting (growing) or dissolving are fundamental to questions of reef health and resiliency. The Reefscape Characterization task of the Coral Reef Ecosystem Studies (CREST) project is focused on geochemical, geologic, and metabolic processes that affect carbonate precipitation and dissolution on coral reefs. For the 1-km x 1-km study

The National Assessment of Coastal Change Hazards project derives features of beach morphology from lidar elevation data for the purpose of understanding and predicting storm impacts to our nation's coastlines. This dataset defines mean beach slopes along the United States Northeast Atlantic Ocean for New Jersey for data collected at various times between 2007 and 2014. For further information reg

These Digital Elevation Model (DEM) and XYZ datasets provide lidar-derived bare-earth topography for Fire Island, New York. Elevation measurements were acquired on October 25 and November 8, 2002 by the first-generation Experimental Advanced Airborne Research Lidar (EAARL) in cooperation with the National Park Service (NPS) and the National Aeronautics and Space Administration (NASA).

Massive corals are used as environmental recorders throughout the tropics and subtropics to study environmental variability during time periods preceding ocean-observing instrumentation. However, careful testing of paleoproxies is necessary to validate the environmental-proxy record throughout a range of conditions experienced by the recording organisms. As part of the USGS Coral Reef Ecosystems S

As part of the Coastal Storm Modeling System (CoSMoS), time series of hindcast, historical, and 21st-century nearshore wave parameters (wave height, period, and direction) were simulated for the southern California coast from Point Conception to the Mexican border. The hindcast (1980-2010) time series represents reanalysis-forced offshore waves propagated to the nearshore, whereas the historical (

The salt marsh complex of the Edwin B. Forsythe National Wildlife Refuge (EBFNWR), which spans over Great Bay, Little Egg Harbor, and Barnegat Bay (New Jersey, USA), was delineated to smaller, conceptual marsh units by geoprocessing of surface elevation data. Flow accumulation based on the relative elevation of each location is used to determine the ridge lines that separate each marsh unit while
