Many species of fish in the Piti Bomb Holes Marine Preserve off Piti, Guam.

 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.

The turbid waters of the Elwha River and the coastal waters of the Strait of Juan de Fuca mix directly offshore of the river mouth, forming a large coastal plume.  This plume is easily identified by the cloudiness of the water (or "turbidity") resulting from sediment discharged by the river.  Two large dams on the Elwha River were incrementally r

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.

USGS scientists Amy Draut (left) and Josh Logan set up a ground-based lidar (light detection and ranging) scanner to measure the topography of the lower Elwha River flood plain.

Photographs from Arahama beach on the Sendai coastal plain taken (A) before (April 11, 2010) and (B) after (May 4, 2011) the tsunami show damage to vegetation, landscape, and buildings. The buildings at far right and left were completely destroyed; all that remains are their foundations.

U.S. Geological Survey geographer Nadine Golden (center, kneeling) works with USGS marine operations staffer Cordell Johnson (right) and a deckhand (left) to deploy a camera sled from the research vessel Coral Sea. The sled is towed close to the seafloor and collects real-time photographs and videos.

The airgun sled is painted orange and suspended from the A-frame.  The three airguns are suspended beneath the sled. The multichannel digital streamer (yellow cable going into the water from the sled) is towed from the the weighted sled to keep it under the ice. This photo shows the number of crew required to safely deploy the airgun sled.
