A NOAA image of the bathymetry north of Puerto Rico. Two ancient submarine landslides are visible as head scarps (labeled Loiza and Arecibo Amphitheaters). Seafloor fissures are indicated by black arrows, and dashed lines outline debris flows from past failures. Map annotated by Uri ten Brink, USGS

Contour plots of SSC for the spatial surveys during trade-wind conditions on the reef flat. (a) SSC from the low tide survey. The highest SSC (60e70 mg/l) were located in a nearshore band, and east of the fish ponds and Kaunakakai wharf. (b) SSC from the high tide surveys.

A multibeam bathymetric survey that produced unprecedented high resolution images of the mouth of San Francisco Bay was conducted in 2004 and 2005.

Digital still photograph from Massachusetts Bay near Cohasset, MA, showing seastars (Asterias sp.), blood stars (Henricia sanguinolenta), blood drop tunicates (Dendrodoa carnea), mussels, and barnacles on cobbles and boulders covered with bubblegum algae and red filamentous algae. Water depth at this location is approximately 19.6 meters.

Photograph of Pingok Island, Alaska, reveals physical features of a changing Arctic: collapsing bluffs, salt-killed tundra (lighter brown near the bluff edge), and drained thermokarst lakes (rust-colored depressions).

This photograph shows caribou tracks on ice-wedge polygons near Garry Creek in Alaska. Coastal erosion along the Arctic coast is chronic, widespread and potentially accelerating, posing threats to infrastructure important for defense and energy purposes, natural shoreline habitats and nearby Native communities.

An oblique aerial photograph shows the currently active Long Range Radar Site on Barter Island, formerly a DEW Line (Distant Early Warning) station that was deactivated in 1990. The Cold War-era landfill in the foreground of the photograph was at immediate risk from coastal erosion in 2006 and has since been relocated farther inland.

Coral atolls are normally long, thin bars of white sand that rise just a few meters above sea level. The island or island group surrounds a hollow center where a volcanic peak once was. The atoll shown in this photo-like satellite image is the island of Tureia, in French Polynesia, in the South Pacific Ocean.
