Gas hydrate at the seafloor on the U.S. Atlantic margin.

Gas hydrate at the seafloor on the U.S. Atlantic margin. The icy deposit formed as gas bubbles emitted from the seafloor transformed into methane hydrate beneath the overhanging rock.

Acoustic Backscatter Intensity

Acoustic backscatter intensity data are an indication of the relative hardness or softness of the sea floor, which is closely related to sediment texture and cohesion. The map shows acoustic backscatter intensity of the sea floor in the Buzzards Bay, Massachusetts. In general, higher values (light tones) represent rock, boulders, cobbles, gravel, shell reefs, and coarse

a Virginia beach before and after Hurricane Sandy

Overwash processes caused by storms, like the one seen here following Hurricane Sandy on a barrier island in Virginia, push sand landward over dunes to create low-elevation, minimally vegetated sandy habitats used by a variety of species, like piping plovers.

Lobster

Digital still photograph from Ipswich Bay near Salisbury, MA, showing a lobster, sponges, and brachiopods, on cobbles and ledge covered with bubblegum algae and red filamentous algae.  A thin veneer of coarse sand and gravelly sediment partially cover the rocks. Water depth at this location is approximately 24 meters.

Acoustic backscatter and bathymetry maps

 

Maps showing (A) acoustic backscatter and (B) bathymetry collected with the inteferomentric sonar.  High backscatter is displayed by light tones and low backscatter is displayed as dark tones within the backscatter image.  Regional bathymetric contours are in meters.  West of Watch Hill, the modern sand deposit is organized into a series of shoreface-attached
