Bottom Photography
Between 2 and 8 bottom photographs and several minutes of video were taken at each station in the study area (fig. 24). The photographic data show that sandy areas of the sea floor are generally rippled, with shells commonly collecting in the ripple troughs, and that burrows, crabs, and fish are often present (fig. 25). Boulders tend to have hydrozoans and sponges and (or) tunicates attached to them, and fish are generally in the surrounding water (fig. 26).
Low-resolution images (150 x 113 pixels) of the photographs can be viewed as thumbnails in the photograph gallery below. These thumbnails are linked to medium-resolution images (600 x 450 pixels) for more detailed viewing. A compressed file with all the medium-resolution images can be accessed by clicking here. The compressed file also contains metadata about the photographs and their acquisition. Alternatively, a compressed file containing the full-resolution images (3648 x 2736 pixels) and metadata can be accessed by clicking here. The images can be identified by using the .jpg image names in the gallery below.
