This geonarrative constitutes the Decadal Science Strategy of the USGS's Coastal and Marine Hazards and Resources Program for 2020 to 2030.
The Decadal Science Strategy of the Coastal and Marine Hazards and Resources Program (CMHRP) describes the CMHRP's vision and mission and the strategic framework needed to support key program goals: Conduct research and develop science-based tools that lead to safer, more productive coastal communities and improved stewardship of natural resources.

Delineating the U.S. Extended Continental ShelfThe United States has an interest in knowing the full extent of its continental shelf beyond 200 nautical miles from shore (called the extended continental shelf, or ECS) so that it can better protect, manage and use the resources of the seabed and subsoil contained therein. The USGS contributes to the ECS effort through membership and leadership on the interagency U.S. ECS Task Force, a group...

Climate Change on U.S. Arctic Ocean MarginsArctic Alaska is warming faster than the rest of the United States. A major consequence of this warming is permafrost thaw, which threatens infrastructure, alters habitat, increases fire risk, changes nutrient and sediment delivery to the coastal ocean, and enhances greenhouse gas release. The warming climate has already dramatically reduced the thickness and annual duration of sea ice, rendering...
Atlantic and Gulf of Mexico Submarine Landslides-Tsunami Hazards ProjectSubmarine landslides and tsunamis along the U.S. Atlantic and Gulf of Mexico coasts are rare, but the risks associated with these natural hazards are high. While most earthquakes in these margins are low in magnitude, and so shaking from them is not intense, they can still cause a lot of damage. The Atlantic and Gulf of Mexico margins are heavily urbanized, support extensive port and industrial...
Deep Sea CoralsDeep-sea corals are slow-growing marine organisms that live at water depths greater than light can penetrate. These corals are widely distributed on the outer continental shelves and slopes of U.S. margins and are considered especially vulnerable to damage by activities such as trawling given their slow regeneration time.
Measuring Sediment Flux in Blackwater National Wildlife RefugeThe Blackwater National Wildlife Refuge (NWR), Maryland, is a tidal wetland complex that has rapidly lost vegetated marsh to open water due to invasive species, sea level rise, and landscape change. The stability of this wetland complex and others nationally has consequences for habitat availability, retention of carbon stores in soils, and coastal flood protection.
Caribbean Tsunami and Earthquake HazardsFour million U.S. citizens live along the coastlines of Puerto Rico and the U.S. Virgin Islands, an earthquake- and tsunami-prone active tectonic plate boundary. A tsunami generated at the subduction zone boundary offshore Puerto Rico could also affect the U.S. Atlantic coast.
The Coupled Ocean-Atmosphere-Wave-Sediment Transport Modeling SystemTo responsibly manage our coastal resources requires an understanding of the processes responsible for coastal change. The CMHRP developed a Coupled Ocean–Atmosphere–Wave–Sediment Transport (COAWST) modeling system that allows the user to evaluate how different processes such as winds and waves, combined with sediment transport, interact with coastlines to modify them. Users can change model...
The Coastal Storm Modeling SystemThe Coastal Storm Modeling System (CoSMoS) provides emergency responders and coastal planners with critical storm-hazard information such as flood extent, flood depth, duration of flooding, wave height, and currents that can be used to increase public safety, mitigate physical damages, and more effectively manage complex coastal settings. The CMHRP initially developed CoSMoS in collaboration with...
Elwha River Restoration ProjectFrom 2011 to 2014, the Nation’s largest dam removal project to date took place in Washington State, allowing the Elwha River to once again flow unimpeded from its origin in the Olympic Mountains to the Strait of Juan de Fuca. Nearly 100 years of sediment (30 million tons) had accumulated behind two dams, and about two-thirds of that (20 million tons) was released, dramatically affecting the river...
CMHRP Response to Hurricane Sandy in Estuaries and WetlandsIn late October 2012, Hurricane Sandy made landfall on the eastern seaboard of the United States, affecting the coastline from North Carolina to New York and Massachusetts. In addition to causing more than 200 human fatalities, the storm altered coastal landscapes, geology, hydrology, environmental quality, and ecosystems. Damage to infrastructure from Hurricane Sandy totaled over $75 billion...
