Data about Earth and its resources are only useful if available in a format that is understandable and accessible. We provide the Nation with ready access to natural science information that supports smart decisions about how to respond to natural risks and manage natural resources.
Coral cover and health determined from seafloor photographs and diver observations, West Hawai'i, 2010-2011
The data described here were collected as part of a larger study to examine habitat conditions and coral health with respect to exposure to submarine groundwater discharge (SGD) and urban land uses.
The Coastal Storm Modeling System (CoSMoS) makes detailed predictions (meter-scale) over large geographic scales (100s of kilometers) of storm-induced coastal flooding and erosion for both current and future sea-level rise (SLR) scenarios. CoSMoS v3.0 for Southern California shows projections for future climate scenarios (sea-level rise and storms) to provide emergency responders and...
The online Catalog provides easy public Web site access to this vital information for the global community. Through greater access to and understanding of these vital test sites and their use, the validity and utility of information gained from Earth remote sensing will continue to improve.
The objective was to compare an urbanized wetland with limited sediment supply (Seal Beach) with a less modified marsh (Pt. Mugu) with fluvial sediment supply. Marine temperature, conductivity, pressure sensors, optical turbidity sensors and acoustic velocity meters were deployed on bottom platforms to quantify the conditions in the water column.
Oceanographic, Atmospheric and Water-Quality Measurements Sandwich Town Neck Beach, Massachusetts, 2016
These measurements provide information about waves, tides, and overwash during a winter storm in January 2016; about waves, tides, currents, and water properties between February and May, 2016; and about waves and tides between May and June 2016, during a period that overlaps with offshore bathymetric surveys.
Oceanographic, Atmospheric and Water-Quality Measurements Sandwich Town Neck Beach, Massachusetts, 2017
These measurements provide short-duration datasets of waves, tides, and overwash from portable pressure sensors deployed on the beach during major winter storms on these dates: January 23-26; February 9-10; February 13-15; and March 13-15, 2017. Longer datasets were obtained from sensors on a platform deployed on the seafloor north of the beach in seven meters depth.
Oceanographic and Water Quality Measurements Collected in Grand Bay, Alabama/Mississippi, August 2016 – January 2017
Suspended-sediment transport is a critical element governing the geomorphology of tidal marshes and estuaries. Marshes rely both on organic material and inorganic sediment deposition to maintain their elevation relative to sea-level. Additionally, horizontal marsh extent is altered by lateral erosion and accretion.
To support the modeling of storm-induced flooding, the USGS Coastal National Elevation Database (CoNED) Applications Project has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for the Southern California Coast and Channel Islands.

Grand Canyon Sandbar Monitoring
The Grand Canyon Monitoring and Research Center, in conjunction with Northern Arizona University, monitors changes to sandbars along the Colorado River downstream of Glen Canyon Dam near Page, Arizona.

The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. The shoreline position and change rate are used to inform management decisions regarding the erosion of coastal resources.
