An underwater volcano near the Polynesian island of Tonga in the Ocean erupted two weeks ago, creating large quantities of ash and rock fragments in the Pacific Ocean that head for the Great Barrier Reef. NASA said the volcano erupted for the first time since 2001, and that could mean good news for the Great Barrier Reef, the world's largest coral reef system. The Great Barrier Reef is dying at an astounding rate, with a 50 percent drop in coral cover between 1985 and 2012, according to the Barrier Reef Foundation.
Climate change has led to extreme coral bleaching, where the water gets too warm and corals expel the algae that live in their tissues, causing the corals to turn white completely and eventually die.
Fewer corals result in fewer habitats for marine life in the devastating cycle of the already fragile marine ecosystem. [1
This is because during the pumice trip to the Great Barrier Reef, experts believe that it will act as a temporary marine habitat for
The hope is that when it reaches the Great Barrier Reef, it will deposit some of the findings collected in the coral system, which will be "a potential mechanism to restore the Great Barrier Reef. "
Queensland University of Technology geologist Scott Bryan told the Guardian:" Based on past events, the salvo raft that we have studied over the last 20 years will bring new healthy corals and other reef dwellers to the Great Barrier Reef.
"Every piece of pumice stone is rafting. It is a home and vehicle for marine organisms to attach and make travel across the deep ocean to reach Australia. ”
Writing on Discover Magazine's blog, volcanologist Eric Klemety of Denison University says: for years, it slowly diffuses into the ocean currents. These pieces of pumice eventually make excellent, floating homes for marine organisms, helping them to spread.

silica as rhyolite. "
He at NASA's Earth Observatory writes:" On August 13, 2019, Landsat 8's Operational Land Imager acquired natural images of a huge pumice raft floating in the tropical Pacific Ocean near the Late Island Tonga.
"NASA Terra Terror Opened Mass on Floating Rock on August 9; the bleached water around the pumice stone indicates that the submarine's volcano is somewhere below.
'By August 13, the lard was sailing southwest. By August 22, the raft had moved north again and was a little more scattered, but still visible. “
