Sea-floor photography was collected at 25 stations within the H11922 survey area as part of this study (fig. 17). The small SEABOSS system aboard the RV Rafael and the SEABOSS system aboard the RV Connecticut were used to obtain video photography and 1 to 8 still photographs at each station as the vessels drifted over the seabed for 2 to 5 minutes. A total of 93 still photographs of the sea floor were obtained. The field of view of each image is approximately 50 cm wide (SEABOSS 50 cm above the bottom).
Low-resolution images (150 pixels wide) of the photographs may be viewed by browsing the thumbnails in the photo gallery below. These thumbnails are hyperlinked to medium-resolution images (600 pixels wide) for more detailed viewing. Alternatively, the directory containing the full-resolution images may be accessed by clicking here. These full-resolution images can be identified using the JPEG image names in the gallery below. Textural analyses of samples obtained at these stations, where available, and discussions of the sediment distribution are provided in the Data Catalog and Sediments sections of this report, respectively.
922-1 / Boulders overgrown primarily with hydrozoans and some hydroids and rust-colored algae. Rippled sand with pea- to pebble-sized gravel and shells and shell hash cover the sea floor between the boulders. A thin veneer of fine-grained siliciclastic or organic debris covers the rocks. Lobster, anemones, and starfish are present. |
