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.

An aerial view of Dauphin Island, Alabama, shows a thin strip of road partially covered by sand, with undeveloped beach in the foreground and developed beach in the background.

 The map view in the center of the sheet is similar to the colored shaded-relief bathymetry map of Hueneme Canyon and vicinity (sheet 1 of this report). Numbered arrows show viewing directions of the perspective views on this sheet (figs.

Pacific sand lance captured in a beach seine. Sand lance are a forage fish that underpin Puget Sound food webs and are intimately connected to Puget Sound beaches. The fish spend a portion of their time buried in the sand and eggs are laid on the upper beach, making healthy beaches critical to the success of this species.

USGS scientist Collin Smith, aboard USGS research vessel Dogfish, sets out a sampling net—called a lampara net—to capture nearshore fishes in a subtidal eelgrass bed in Eagle Harbor, Bainbridge Island, Washington.

Bird's-eye view map of a section of the seafloor off southern California, made with depth data. The map shows a channel wall that has been cut by the San Diego Trough fault and moved about 20 meters. This feature is about 1,000 meters below sea level.
