National Shoreline Change

June 17, 2020

Exploring Shoreline Positions of the United States From the 1800s To The Present. This geonarrative explains how the USGS derives shorelines from various data sources, and how shoreline change rates are generated from these data. The Natural Hazards Mission Area programs of the USGS develop and apply hazard science to help protect the safety, security, and economic well-being of the Nation.

The series of geonarratives introduces partners and stakeholders to the data and tools available to them through the Coastal Change Hazards program.

Coastal Change Hazards

Natural processes such as waves, tides, and weather, continually change coastal landscapes. The integrity of coastal homes, businesses, and infrastructure can be threatened by hazards associated with event-driven changes, such as extreme storms and their impacts on beach and dune erosion, or longer-term, cumulative changes associated with coastal and marine processes, such as sea-level rise...

Coastal Change in Alaska

Alaska's north coast has been home to indigenous communities for centuries. Changing coastlines threaten important infrastructure and historic sites that support indigenous communities. Changing coastlines also can potentially reduce habitat for Arctic wildlife, such as polar bears, shorebirds, and walruses.

The Role of U.S. Coral Reefs in Coastal Protection

U.S. Geological Survey scientists have shown that along with providing food, tourism, and biodiversity, coral reefs also protect dollars and lives. This interactive geonarrative introduces the USGS research to understand the role of US coral reefs in coastal protection.

Barrier Islands

U.S. Geological Survey Researchers Monitor Barrier Islands. This geonarrative features research used to monitor Barrier islands which are narrow stretches of sand deposited parallel to the shoreline, are inherently valuable ecosystems. They protect estuaries and lagoons that help reduce coastal erosion, purify the water, and provide habitat for fish and birds.
