Figure F6. Seafloor photographs from Leg 194 sites. Phototrigger at upper right of each photograph is 10 cm in diameter. A. Seafloor photograph at Site 1194 at 374 mbsl shows decimeter-range sediment ripples and cemented pieces. The cut section of a dredged cemented piece reveals a burrow heavily encrusted by sponges suggesting early cementation occurring on the seafloor. B. Dredged submarine crust from Site 1196. The photo shows the underside of a 2- to 3-cm-thick reddened crust colonized by bryozoans and serpulids. C. Seafloor photographs at Site 1196 at 304 mbsl, showing patchy distribution of the hardground crust on the drowned MP3 platform top. D. Seafloor photograph at Site 1193 at 348 mbsl. Abundant decimeter-scale ripples document strong bottom currents.
