Fig. 3 — Images taken from the forward-looking ROV cameras of lava, domes, and clastic deposits. Line in each image is 1 m in length. (A) GP clasts are predominantly meter-sized; the clast shown here is 6 m in diameter. (B) Meter-sized GP clasts are stacked more than four clasts high within the caldera, suggesting gentle settling to the seafloor from suspension. (C) GP clasts commonly have curviplanar surfaces and quenched margins with normal joints and breadcrusting. (D) Lava spine on dome O-P. (E) ALB deposit at 1.2 km from the inferred source vent (dome O-P). (F) AL deposit on top of a GP clast; inset shows the complex internal stratigraphy of this unit.
