National Shoreline Change Data Catalog

The U.S. Geological Survey (USGS) maintains shoreline positions for the United States coasts from both older sources, such as aerial photos or topographic surveys, as well as contemporary sources like lidar elevation point clouds and digital elevation models (DEMs). These shorelines are compiled and analyzed in the Digital Shoreline Analysis System (DSAS) software to compute rates of change. It is important to keep, and make available, records of historical shoreline positions to allow monitoring of change over time, and to identify areas most susceptible to erosion or accretion. These data can help coastal managers identify areas of the coast that are most likely to experience significant change over time. This...

U.S. Geological Survey Hydrodynamic Model Simulations

A collection of hydrodynamic model simulations, their inputs, outputs by USGS Woods Hole Coastal and Marine Science Center. For more information on the Coupled Ocean Atmospheric Wave Sediment Transport (COAWST) modeling system see https://code.usgs.gov/coawstmodel/COAWST. Aboout the Estuarine Processes, Hazards, and Ecosystems Team At the U.S. Geological Survey's Woods Hole Coastal and Marine Science Center we undertake interdisciplinary projects that aim to quantify and understand estuarine processes through observations and numerical modeling. Both the spatial and temporal scales of these mechanisms are important, and therefore require modern instrumentation and state-of-the-art hydrodynamic models. These are...

Coastal Wetlands Synthesis Products

Visit the USGS story map, U.S. Coastal Wetland Synthesis, to experience our wetlands syntehsis study interactively. Aboout the Estuarine Processes, Hazards, and Ecosystems Team At the U.S. Geological Survey's Woods Hole Coastal and Marine Science Center we undertake interdisciplinary projects that aim to quantify and understand estuarine processes through observations and numerical modeling. Both the spatial and temporal scales of these mechanisms are important, and therefore require modern instrumentation and state-of-the-art hydrodynamic models. These are mostly collaborative projects that include participation from other U.S. Geological Survey offices, other federal and state agencies, and academic institutions....

Environmental Geochemistry and Wetland Science

The Environmental Geochemistry and Wetland Science Community is a place to organize Science Base Data Releases and links for associated publications concerning the ecology, biogeochemistry, and resilience of coastal wetlands. Coastal wetlands provide critical ecosystem services, including carbon sequestration. Many coastal marshes are altered due to human management actions that disrupt key biogeochemical feedbacks. Within this ScienceBase Community, data that supports publications on these topics is orgaznized in two ways: 1) publications with similar research topics are grouped within the same sub-categories (Blue Carbon and Coastal Carbon Studies or Coastal Groundwater Studies are the primary research areas)...
