Abstract

Corals in the Mesophotic Zone (40–115 m) at the Barrier Reef Complex From San Andrés Island (Southwestern Caribbean)

Highlights

  • Shallow reefs in the SeaFlower Biosphere Reserve, even at the remotest bank atolls, are showing a steady decline in coral cover overall health condition during the last 20 years (Sánchez et al, 2019b)

  • We explored the reef using Close-Circuit Rebreather (CCR) (Megalodon, Inner Space Systems) and hypoxic trimix techniques (e.g., 11% Oxygen and 60% Helium) with complete bail-out support for each diver

  • The dataset included 113 specimens from 33 species collected below 40 m (8 black corals, 1 lace coral, 8 scleractinian corals, and 16 gorgonian corals: Table 1)
