A total of 75 still photographs of the sea floor were obtained at 19 locations as part of this study (fig. 12). The small SEABOSS system was used to obtain 2 to 7 still photographs at each station as the RV Rafael drifted over the seabed for 2 to 5 minutes. The field of view of each image is approximately 50 cm wide (small 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 .jpg image names in galleries below. Textural analyses of samples obtained at these stations, where available, are provided in the Sediment Distribution section of this report.
RP8 / Gravel, gravelly sediment, and scattered boulders covered with barnacles and sponges. Abundant mussel shell debris with some surf clam and quahog shells. Sand patches, where present, are current rippled. |
