A submarine volcano near the Polynesian island of Tonga in Oceana exploded two weeks ago, causing much of the ash and debris in the Pacific, heading for the Great Barrier Reef. NASA stated that it was the first time since 2001 that the volcano erupted. This could be good news for the Great Barrier Reef – the largest coral reef system in the world. According to the Barrier Reef Foundation, the Great Barrier Reef has declined remarkably fast with a 50 percent drop in coral coverage between 1985 and 2012.
Climate change has led to extreme coral bleaching, which also causes water to warm up and the corals displace the algae that live in their tissues, causing the corals to completely whitewash and eventually die.
Fewer corals lead to less habitat for marine life in a devastating cycle for the already fragile marine ecosystem. [1
The hope is that upon reaching the Great Barrier Reef, they will disclose some of the accumulated knowledge in the coral system, which will be a "potential mechanism." Scott Bryan, a geologist at Queensland University of Technology, told the Guardian, "Because of the pumice events Over the past 20 years, we have been bringing new healthy corals and other reef inhabitants to Queensland the Great Barrier Reef.
"Every piece of pumice is a rafting vehicle. It is a home and vehicle for marine organisms to travel across the deep ocean to Australia.
Volcanologist Erik Klemetti of Denison University wrote on Discover Magazine's blog: "Pumice rafts can drift for weeks to years, slowly dissipating in ocean currents. These pumice boulders are ultimately an excellent home for marine organisms, helping them to spread.

"The erupted pumice stone means that this volcano erupts magma high in silica such as rhyolite . " of a giant pumice raft floating in the tropical Pacific Ocean near Late Island in the Kingdom of Tonga.
"NASA's Terra satellite discovered the mass of the floating rock on 9th August. The discolored water around the pumice indicates that the submarine volcano is somewhere below.
"On the 13th of August the raft was driven to the southwest. From the 22nd of August the raft had gone north again, a bit more scattered but still visible. "
