A giant pumice tree floating in the Pacific can help cure Australia's Great Barrier Reef



The massive floating volcanic rock sheet was first spotted by sailors on August 9, days after it was thought to have erupted an underwater volcano near the Pacific Island of Tonga, according to NASA's Earth Observatory.

Days later, Australian sailors heading to Vanatou on a ROAM catamaran said they encountered volcanic rocks "made up of marble pumice stone to the size of a basketball so no water could be seen." [19659003] The crew of ROAM Michael and Larissa Holt told CNN that they had been at sea for 10 days before coming into contact with the gray floating matter one evening.

"It was actually quite ominous," Larissa said. "The whole ocean was dull – we couldn't see the reflection of the water of the moon."

"The rocks somehow closed around us, so we couldn't even see our wake or wake. he could just see the edge where he returns to plain water ̵

1; shiny water – at night, "Michael added, stating that they could see the rock from any direction.

" It was a little mystery, we didn't know how deep it was. if we were sailing over a volcano that was active at that moment. It looked like it was coming up more, bubbling underneath, "Larissa said.

The pumice stone, which is filled with holes and cavities, floats like an iceberg, with about 90% under water and 10% above water, the couple explained.

This pumice stone is expected to move downstream to the Australian coast over the next 7-10 months, they said, where scientists believe it can have a positive effect on the microorganisms there.

This is because floating stones can act as a home for a nest of marine organisms.

As the pumice stone travels to the Great Barrier Reef, the marine life attached to it will also travel, potentially bringing in a variety of new colonies of bananas, corals, and more.

In 2012, Assistant Professor at Queensland University of Technology Scott Brian and others after a similar underwater volcanic event found that pumice rafts were one of the ways the ocean could redistribute diverse marine life.

The eruption this month could have similar positive effects, Brian said.

In a conversation with the Australian Broadcasting Corporation (ABC) on Friday, Brian said: "[The raft] is a natural mechanism for colonizing species, restoring and growing in a new environment," adding that this is only "one of the ways nature can help encourage Brian also said that the natural phenomenon occurs every five years.

He told ABC that when pumice water reaches Australia's coastline in the next seven to 12 months, it will be "covered. across a range of algae and barrel organisms, corals and crustaceans and snails and worms. "

" This is a way for healthy, young corals to be quickly introduced into the Great Barrier Reef, "he said.

In 2016 and 2017, the sea heat waves caused by climate change led to mass bleaching that killed about half of the Great Barrier Reef corals, along with many others around the world.
