Resurrection Bay on August 8, 2016. The water appeared calm in the shelter of the inner bay, but closer to the entrance, swells coming in from the Gulf of Alaska were breaking on a small beach where the three boaters had capsized.

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.

Perspective views of multibeam bathymetry data acquired by the USGS aboard the R/V Medeia. Shallower depths in red. Arrows point to the distinct line in the seafloor associated with the Queen Charlotte-Fairweather fault.
