How projections in CoSMoS work
CoSMoS’s approach to projecting flood hazards: global winds, waves, tides, and anomalous water levels are scaled down to the local scale for projecting nearshore wave heights, flooding, and shoreline change, including beach erosion and cliff failures.

Research vessel tracklines offshore of southeast Alaska
Tracklines along which R/V Ocean Starr (2017, red lines) and R/V Norseman (2016, black lines) conducted seismic-reflection surveys, overlaid on high-resolution bathymetry (color background). Yellow stars represent earthquakes of magnitude (M) 7 and greater since 1900.

Examples of sediment dynamics offshore of barrier islands
Examples of sediment dynamics offshore of barrier islands include the development and erosion of shoals, tidal deltas, and sand ridges.

Maps with key features and shaded relief of the study area
Left: Key features in and around the Gulf of Alaska. A black rectangle outlines our 2016 study area along the Queen Charlotte-Fairweather fault. Red arrows indicate relative tectonic plate motions. Right: A shaded relief map of the 2016 study area. Rainbow colors show seafloor depths acquired by the USGS in 2015 and 2016. Red indicates shallower depths.
