Animation displays modeled beach profile elevation as it has evolved at Fishing Point, Virginia. These data are based on historical charts and images and measure distance (in kilometers) of cross-shore accretion. Q_S is the flux of sand to the beach, and Q_D is the flux of sand from the beach to the active dune.

Overview of Taan Fiord. Inset showing location of Taan Fiord, Alaska in Wrangell St. Elias National Park and Preserve. Taan Fiord is about 100 km from the nearest town, Yakutat, AK. Landsat 8 image of Taan Fiord acquired in 2016. Vegetation loss is clear near the water line.

A USGS scientist navigates a personal watercraft (PWC) slowly through Elkhorn Slough. The PWC is equipped with an echosounder and GPS, to record accurate depth and location. This mapping effort is part of recurring surveys in the Monterey Bay area.

A USGS scientist navigates a personal watercraft equipped with sonar and GPS to collect depth information (bathymetry) of the nearshore. This mapping effort is part of recurring surveys in the Monterey Bay area.

A USGS scientist walks along Santa Cruz Main Beach at the edge of the San Lorenzo River in Santa Cruz, California, wearing a backpack with GPS equipment. She is collecting elevation data that will be used to create a topographic map of the beach. This mapping effort is part of recurring surveys in the Monterey Bay area.

The USGS St. Petersburg Coastal and Marine Science Center strives to provide timely, robust science using modern methods and state-of-the-art technologies. This involves keeping our facilities and equipment updated.

The USGS St. Petersburg Coastal and Marine Science Center conducted outreach at the Localtopia Event held in February 2020. Staff demonstrated a simulation of how storms can impact sandy coastlines through processes such as erosion.
