Plate 15.—OCEAN-BOTTOM PHOTOGRAPHS OF SEAMOUNTS
- Figure 1. (Station V4-12, photo 16) Depth 700 fathoms, location 35° 12´N., 15° 18´W., on seamount of the Horseshoe Group. Note bioclastic debris lodged in depressions on the rocky bottom. Photographs shown in Figures 1, 2, and 3 are no more than a few hundred feet apart.
- Figure 2. (Station V4-12, photo 10) Depth 700 fathoms, location 35° 12´N., 15° 18´W. Rippled sandy bottom.
- Figure 3. (Station V4-12, photo 7) Depth 710 fathoms, location same as Figures 1 and 2. Note current ripple marks. The photograph indicates an appreciable current from left to right.
- Figure 4. (Station V4-16, photo 19) Depth 1100 fathoms, location 35° 07´N., 13° 04´W., on the side of Ampere Seamount. Note winnow row of dark and light gravel-sized detritus which resembles similar material on the Rift Mountains shown in Figure 1 of Plate 19.
- Figure 5. (Station V4-18, photo 26) Depth 75 fathoms, location 35° 10´N., 12° 55´W., near the top of Ampere Seamount.
- Figure 6. (Station V4-14, photo 47) Depth 1100 fathoms, location 35° 12´N., 15° 22´W. on same seamount as Figures 1-3. Bottom appears to consist of light-colored sediment thinly veiled by dark coarser sediment. The white polka dots appear to represent piles of the underlying light sediment brought to the surface by burrowers.
