Coastal and Marine Hazards and Resources Program

Multimedia

The Coastal and Marine Hazards and Resources Program shares a wide range of resources to help explain and illustrate scientific concepts, our scientific activities, expertise, technology, tools, and other educational resources. Through newsletters, multimedia resources, special events, and other products, you can learn more about the many ways our science supports the Nation.

Lesson plan key for identifying coral condition

Key used in an educational lesson plan for identifying the composition and condition of corals and coralline algae in a core. (a) Two examples of Pocillopora in good taphonomic condition (<50% erosion or encrustation of the skeleton). Intervals in cores during which Pocillopora skeletons dominate and are in good condition represent times of good coral growth and active

Cedar Island, Virginia 1994 - 2014

Cedar Island, Virginia is an uninhabited barrier that has migrated landward approximately 15-30 meters per year since 1984 due to its low sediment supply. The shoreface slope is gradual but almost entirely devoid of island sediment - both responses to its recent, rapid retreat. USGS scientists collect geologic and morphologic data from this island’s shoreface. The

Fire Island, New York 1994 - 2014

Fire Island, New York is sparsely populated and regularly nourished, but has few modifications that impede natural sediment exchanges. Shoreface geomorphology reflects past periods of seaward progradation and alongshore extension resulting in a relatively sediment-rich shoreface. USGS scientists collect geologic and morphologic data from this island’s shoreface. The

Rockaway Beach, New York 1994 - 2014

Rockaway Beach, New York is heavily developed, has seawalls and groins and is regularly nourished. It hasn’t changed much over 20 years. The shoreface is steep and sediment cover doesn’t extend far from shore—likely the result of being fixed in place for decades. USGS scientists collect geologic and morphologic data from this island’s shoreface. The shoreface is an

Modeled beach profile evolution at Parramore Island, Virginia

Animation displays modeled beach profile elevation as it has evolved at Parramore Island, Virginia. These data are based on geomorphic investigation and measure distance (in kilometers) of cross-shore accretion. QS is the flux of sand to the beach, and QD is the flux of sand from the beach to the active dune. Yellow represents sand, blue represents

Modeled beach profile evolution at Fishing Point, Virginia

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. QS is the flux of sand to the beach, and QD is the flux of sand from the beach to the active dune. Yellow represents sand, blue represents

Overview of Taan Fiord

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. The evacuated subaerial landslide area and runout are visible to the left of the fjord head.

USGS Erosion Simulation Video

This video demonstrates a simulation of how storms can impact sandy coastlines through processes such as erosion. This demonstration is conducted at outreach events by scientists at the St. Petersburg Coastal and Marine Science Center. The activity can also be re-created at home or in the classroom.
