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. Oil- and gas-related development sites and U.S. Department of Defense installations

Coastal Storms

U.S. Geological Survey scientists study our coasts to understand how they respond to storms today. But rising sea levels and a changing climate will alter these natural cycles in the future. This geonarrative features research used to predict flooding now and into the future.

National Shoreline Change

Exploring Shoreline Positions of the United States From the 1800s To The Present. Beach erosion is a chronic problem for many coastal areas of the United States. This geonarrative explains how the USGS derives shorelines from various data
sources, and how shoreline change rates are generated from these data.

Real-Time Forecasts of Coastal Change

U.S. Geological Survey researchers develop tools to forecast coastal change hazards. This geonarrative features research and tools developed to forecast real-time coastal change.

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.

Coastal Wetlands: The State and Future of a Precious Resource

Coastal wetlands, and salt marshes specifically, are simultaneously geomorphic and biologic systems. They proliferate across a narrow range of elevation, water level, and salinity conditions. Salt marshes rely on their own growth and sediment input to maintain or increase their extent, whereas physical forces such as waves and sea-level rise tend to reduce it.

California Seafloor Mapping Program

The California Seafloor Mapping Program (CSMP) is a cooperative program to create a comprehensive coastal and marine geologic and habitat base map series for California's State waters. Initiated in 2008, the CSMP has collected bathymetry and backscatter data that are being turned into habitat and geologic base maps.
