Bottom Photography Several minutes of video and between two and seven still photographs were obtained at each station as the RV Rafael drifted over the sea floor (fig. 17). Bottom photography shows that silty areas tend to be characterized by numerous burrows in the sea floor, sandy areas commonly exhibit current-formed sand ripples and mobile marine life (such as worms, amphipods, sand dollars, and crabs; fig. 18), and areas with boulders and bedrock tend to be covered with algae, sponges, and hydrozoans (fig. 19).
Low-resolution images (150 x 113 pixels) of the photographs may be viewed by browsing the thumbnails in the “Photograph Gallery” section. These thumbnails are linked to medium-resolution images (600 x 450 pixels) for more detailed viewing. A .zip file with all the medium-resolution images is also available with this report. The .zip file also contains metadata about the photographs and their acquisition. In addition, a .zip file containing the full-resolution images (3,648 x 2,736 pixels) and metadata is also part of this report. The images can be identified by using the .jpg image names in the “Photograph Gallery” section.
