Evidence for and against Flood theories

Even deep-water corals are pretty touchy. When Alvin descended to seamounts in the Pacific, scientists noted many were barren from anaerobic waters caused by plankton decay, others had empty zones on top and a profilic area where oxygen and nutrients were circulated by currents. Even though the spiral black corals were thriving, any alteration in current(oxygen), nutrients and sedimentation (mud) controlled their existence. (Mapping the Deep--Robert Kunzig)
