Preparing for a day of sampling on Grizzly Bay
Scientists from the USGS Pacific Coastal and Marine Science Center in their vessel jewell, docked at Belden's Landing Water Access Facility on Montezuma Slough. They are preparing for a day of sampling on Grizzly Bay, where they study how sediment moves through sensitive coastal environments.
Preparing the GOMEX on Grizzly Bay

California coastline
The U.S. west coast is an area of complex coastal geography. This photograph depicts several examples of geological features along the California coastline that are shaped by varied coastal processes. The gently sloping beach, stark bluffs, and presence of smooth rocks suggests that the coastal processes shaping this coastline are complex.

California coastal erosion
This region of the California coastline is lined with coastal bluffs that have been shaped not only by runoff from rain, but also by wave- and wind-driven erosion. This photo from Pescadero State Beach displays an example of a bluff undergoing erosional processes. Water from the ocean, delivered in waves, can overtop some of these coastal bluffs.

Coastal storm modeling system integrates economic impacts
Patrick Barnard explains how the Coastal Storm Modeling System (CoSMoS) integrates information from the Hazards Exposure Reporting and Analytics (HERA) mapper to understand the social and economic consequences of different flooding scenarios.

Economic benefit of coral reef-lined coastlines in U.S.
Map displaying the distribution of total economic losses (direct building damages and indirect economic disruption) in the U.S. that are prevented from flooding by coral reefs annually. In total, the annual coastal flooding risk reduction benefits provided by U.S. coral reefs exceed $1.8 billion.

Astoria Canyon multibeam bathymetry
Multibeam bathymetry shown in the spectrum from red (shallower) to blue (deeper) for depths greater than 200 m across the head of Astoria Canyon. The land and continental shelf are shown in grayscale slope shading where darker colors represent steeper slopes. The modern Columbia River is far right.

Evolution of shoreline around Elwha River mouth
Evolution of the shoreline around the Elwha River mouth, Washington, before, during and after dam removal, 2011–2017. Two large dams were removed from the Elwha River between 2011 and 2014 in the largest dam removal worldwide thus far, releasing more than 20 million tons of sediment downstream.
