Dr Taylor, who is co-lead of the expedition and Chair of the Deep-Sea Biology Society, said: 鈥淭he discovered reefs are novel for several reasons 鈥 in shallow reefs where finding 10-20% of coral cover would be considered a relatively unhealthy reef, in the deep-sea this is the norm. Dead coral skeletons making up the remaining 80-90% still provide homes for a huge diversity of life, which is less reliant on the live sections of coral. However, the reefs we鈥檝e found in the last few days have 50-60% live coral in many areas, which is very rare indeed.
鈥淭hey are pristine and teeming with life 鈥 pink octopus, batfish, squat lobsters and an array of deep-sea fish, sharks, and rays. These newly discovered reefs are potentially of global significance 鈥 a canary in the mine for other reefs globally 鈥 sites which we can monitor over time to see how pristine habitats evolve with our current climate crisis.鈥
Commenting on this ground-breaking discovery, the Minister of Environment of Ecuador, Jose Antonio D谩valos said: "This is encouraging news. It reaffirms our determination to establish new marine protected areas in Ecuador and to continue promoting the creation of a regional marine protected area in the Eastern Tropical Pacific. The richness of the yet explored depths of our ocean is another reason to strive towards achieving the commitments of the Global Ocean Alliance 30x30, which aims to protect at least 30% of the world's oceans by 2030, aligning sustainable economic activities with conservation."
Prior to this discovery, Wellington Reef off the coast of Darwin Island in the far north of the archipelago was thought to be among the few structural shallow coral reefs in the Gal谩pagos Islands to have survived the 1982-83 El Ni帽o event. The new discovery made during dives by scientists in Alvin shows that sheltered deep-water coral communities have likely persisted for centuries in the depths of the GMR, supporting rich, diverse, and potentially unique marine communities.
Dr Stuart Banks, Senior Marine Researcher at the Charles Darwin Foundation, and national observer on this expedition, added: 鈥淭he captivating thing about these reefs is that they are very old and essentially pristine, unlike those found in many other parts of the world鈥檚 oceans. This gives us reference points to understand their importance for marine natural biodiversity heritage, connectivity with regional MPAs, as well as their role in providing goods and services such as carbon cycling and fisheries. It also helps us reconstruct past ocean environments to understand modern climate change. Open waters cover over 95% of the known GMR, of which less than 5% have been explored through modern research expeditions. It鈥檚 very likely there are more reef structures across different depths waiting to be explored. We鈥檒l forge ahead with the Galapagos National Park Directorate and partners to help ensure that such newly discovered habitats are folded into the GMR and Hermandad Marine Reserve planning process and recognized as part of their considerable world heritage value鈥.
Dr Daniel J. Fornari, co-lead of the expedition, marine geologist, and Emeritus Research Scholar at the Woods Hole Oceanographic Institution who has mapped and sampled the marine environment in the Gal谩pagos for over 20 years, said: 鈥淓xploring, mapping and sampling the Gal谩pagos Platform with Alvin and Atlantis represents an opportunity to apply 21st Century deep-submergence and seafloor mapping technologies and innovative deep-sea imaging techniques to reveal the beauty and complexity of the volcanic and biological processes that makes the Gal谩pagos so unique".
Scientific findings such as this help inform effective management and conservation actions. The discovery also comes at a time when the Eastern Tropical Pacific countries of Panama, Costa Rica, Colombia, and Ecuador are actively collaborating through a regional Marine Corridor (CMAR) initiative to protect and responsibly manage the ocean upon which we as people depend. Newly declared MPAs such as the Hermandad Marine Reserve (HMR) now connect seamounts in Ecuadorian waters to offshore marine environments such as Costa Rica鈥檚 Cocos Island National Park. Natural oceanographic and marine processes transcend national boundaries, which underscores the need for special measures that protect foraging grounds, migratory routes for marine life and sustain responsible fisheries.
The expedition is led by scientists at WHOI, University of Bristol, Boise State University (USA), and 糖心Vlog, in collaboration with the Gal谩pagos National Park Directorate (GNPD), Charles Darwin Foundation and Ecuadorian Navy鈥檚 Oceanographic and Antarctic Institute (INOCAR). The expedition is funded by the US National Science Foundation (NSF) and Natural Environmental Research Council (NERC) in the UK.
