00:25:14 - 20231029T032728Z Note:  there is a high density of corals here but mostly sibogagorgia, some bamboo whips
00:30:36 - 20231029T033250Z Note:  overall in this are is steeper basalt bottom and has a higher density of coral

01:12:22 - 20231029T041436Z Note:  the white corals that have been absorbed I believe is either Paragorgia sp. or Enallopsammia rostrata. the small white look like Enallopsammia rostrata, so perhaps they all are?.
