Marine biologists found two pristine deep-sea coral reefs off the coast of the Galápagos islands this week, certainly one of which is over eight soccer fields lengthy. The reefs sit between 370 and 420 meters beneath the floor, and their discovery expands our understanding of deep, cold-water reefs within the Galápagos Marine Reserve, the primary of which have been discovered just six months ago.
“This data just isn’t solely precious from a scientific perspective, but it surely additionally offers a stable basis for decision-making that successfully protects these ecosystems, safeguarding the organic variety they harbor and guaranteeing their resilience in a consistently altering atmosphere,” mentioned director of the Galápagos Nationwide Park Directorate Danny Rueda Córdova in a press release.
The expedition of 24 scientists representing 13 organizations and universities started on September 18. The smaller of the 2 reefs found measures 250 meters, whereas the bigger is 800 meters lengthy. Each reefs exhibit a wealthy variety of stony coral species, suggesting they’ve been round for 1000’s of years supporting marine biodiversity.
Laser scanning expertise mapped the coral reefs with extraordinarily excessive decision, capturing particulars as small as 2 millimeters. The scans have been able to figuring out animals dwelling on the ocean ground. This was a serious purpose of the expedition, as most underwater mapping expertise can’t picture stay organisms due to the coarse decision.
The primary deep-sea coral reefs within the Galápagos have been found in April, revealing the traditional buildings not beforehand identified to have existed within the area. The unique discovery was made by a human-occupied submersible simply over the ridge of a submerged volcano; high-quality nonetheless pictures and 4k video revealed the breathtaking marine life.
The analysis crew featured scientists from the Schmidt Ocean Institute, Galapagos Nationwide Park Directorate, Charles Darwin Basis (CDF) amongst others.
“Discovering such deep and long-lived reef takes us necessary steps nearer to defending hidden dimensions of ocean variety and understanding the position that deep habitats play in sustaining our ocean’s well being,” mentioned CDF’s Stuart Banks in a press release.
The crew additionally explored seamounts, elevated underwater mountains not fairly tall sufficient to be islands, inside the Isla del Coco Nationwide Marine Park. Researchers noticed a number of deep-sea coral species laden with eggs on these mounts.
