NOAA researchers measured in the Maug Islands the largest Porites coral ever recorded, with 1,347 square meters, in an area crucial for climate studies
NOAA researchers measured in the Maug Islands, in the Mariana archipelago, the largest coral of the Porites genus ever recorded, with about 1,347 square meters and an estimated age of 2,050 years, a discovery that enhances the scientific value of the area.
Unprecedented Measurement
The structure, described by scientists as majestic and cathedral-like, had been known to the local community for some time, but had not yet been properly measured.
The survey surprised the team due to the size achieved by the megacoral.

Only 28% of the ocean floor has been accurately mapped, less than what is already known about the surface of Mars and the Moon, and scientists consider the topic strategic for Brazil, with a global goal to map everything by 2030.

Japan wants to bury a 500 km “cargo conveyor” between Tokyo and Osaka to replace up to 25,000 trucks per day, move goods through tunnels and automated driverless corridors, and avoid a logistical collapse in an increasingly aging country.

Vietnam dumps sand in the South China Sea and transforms disputed reefs into artificial islands with an area equivalent to more than 1,500 football fields, builds 15 ports in the Spratly Islands, and expands bases in the ocean while challenging Chinese pressure in one of the most tense maritime regions on the planet.

Is Rosie from the Jetsons becoming a reality? China tests “robot cleaners” with artificial intelligence inside homes for R$ 114, capable of collecting trash, folding clothes, and mapping apartments, turning domestic cleaning into a living laboratory for companies that want to teach machines to act like humans.
Thomas Oliver stated, in a NOAA statement, that the coral was so large that it could not be easily measured.
Safety restrictions in diving made the work of the researchers difficult during the operation at the site.
Coral Dimensions
According to scientists, the structure is about 31 meters at the top and 62 meters at the base. In addition to the estimated area of 1,347 square meters, the megacoral drew attention for its estimated age of approximately 2,050 years.
Hannah Barkley explained that the age cannot be determined with absolute precision.
Since Porites rus colonies do not produce growth bands like other corals, the estimate considers an outward growth of about one centimeter per year.
Natural Laboratory
The megacoral is located in the volcanic caldera of Maug, an area that scientists classify as a natural laboratory.
The site has unique sources of carbon dioxide, which create regions of high acidity in the ocean and aid in studies on climate change.
In this environment, researchers observe how corals and other organisms may react to these conditions.
The healthy megacoral also contrasts with dead zones located near CO₂ emissions within the same area.
Strategic Region
The Mariana archipelago, of volcanic origin, is located between the Philippines and Japan and is home to the Mariana Trench, known as the deepest point on Earth. For Hannah Barkley, Maug is truly a very special place.
