Figure 15. Locations of stations at which bottom samples and photographs were taken during cruise 08012 of research vessel Rafael to verify acoustic data.

A total of 160 still photographs of the sea floor were obtained at 37 locations as part of this study (fig. 15). The small SEABOSS system was used to obtain 3–6 still photographs at each station as the RV Rafael drifted over the seabed for 2–5 minutes. The width of the field of view of each image is approximately 50 cm (from the 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 by the .jpg image names in the galleries below. Textural analyses of samples obtained at these stations, where available, are provided in the Sediments section of this report.
