Explore ridge benthic coverage starting at 800 m and transiting up the ridge. At approximately 150-200 m, conduct measurements and collections as follows (in order): Photogrammetry – image coral. SOLARIS – measure superoxide; start by measuring seawater ~1 m away from the coral, move wand to surface, move wand to several other areas on the coral surface, then move back to background seawater. Squeezers – if collecting waters at surface, fire a squeezer at the coral surface. Collect coral fragments in coral quivers. Conduct measurements and collections of a couple sponges as follows (in order): SOLARIS – measure superoxide; start by measuring seawater ~1 m away from the sponge, move wand to outside of sponge, move wand inside of sponge, then move back to outside of sponge. Squeezers – collect waters inside sponge. Collect sponge fragments and place in coral quiver. Collect eDNA samples and water samples (Niskins) at sites along transects corresponding to ROS data. Towards end of dive, collect coral fragments for aquaria incubations (one species, multiple fragments).
