A series of eight dives, four with open-circuit scuba and four with closed-circuit rebreathers were made to compare the two diving methodologies. Two criteria were considered: time requirements for topside equipment preparation, and consumption of expendables. The open-circuit divers required four times as much topside equipment preparation as the rebreather divers, consumed 17 times as much gas, and cost seven times more in expendables. These findings indicate significantly less time and an… Expand

A comprehensive investigation of mesophotic coral ecosystems in the Hawaiian Archipelago
TLDR
This work characterized the most expansive MCEs ever recorded, with vast macroalgal communities and areas of 100% coral cover between depths of 50–90 m extending for tens of km2 in the Hawaiian Archipelago, and finds that endemism within M CEs increases with depth, and does not support suggestions of a global faunal break at 60 m.
