NASA News: Manhattan-sized volcanic rock could damage the Great Barrier Reef, experts say | Science news



NASA experts believe that a "Manhattan-sized pumice raft" was created as a result of an underwater volcanic eruption. Simon Boxall, Principal Teaching Fellow at the National Oceanography Center, also claimed that the huge mass could cause "damage" to the Great Barrier Reef. However, the pumice raft could also save the Great Barrier Reef by helping to "sow" the dying coral reef. According to the Barrier Reef Foundation, the Great Barrier Reef died between 1985 and 2012 at an amazing rate of 50 percent less coral.

It may take a month or two to get to Fiji.

"The idea of ​​the Queensland University of Technology, however, is that as the raft continues to move, it moves around the currents to the Great Barrier Reef.

"One hope is that the surface's raft material begins to absorb marine life, things grow on it, as well as algae grow on boats that have just been left in the water.

"So they will get these polyps that form as if they were the seeds of a reef. The hope is that these seeds of a coral reef would eventually drift to Australia and help re-sow parts of the dying Great Barrier Reef.

"Now there is a downside, and the downside is that the raft material could also carry species that cause damage could. Time will tell if this is a good or a bad thing for the Great Barrier Reef.

At the beginning of the interview, Sky News presenter Kay Burley said: "The sailors are warned about a pumice raft to take care of Tonga. The size of Manhattan has formed in the ocean.

"The huge mass has been swimming in the Pacific for two weeks, but scientists are still debating where it comes from. NASA experts believe that the raft is the result of an underwater volcanic eruption. "

Mr. Boxall further stated," Pumice forms when you undergo an underwater volcanic eruption. The molten rock, which is incredibly hot when it comes out of the ground, releases pressure.

"These float and form this huge 1

50-square-kilometer raft that drifts northwards in the ocean currents towards Fiji." [19659003] A submarine volcano near the Polynesian island of Tonga exploded in Oceana two weeks ago and caused ash and stone debris in the Pacific, heading for the Great Barrier Reef.

NASA stated that the volcano erupted for the first time since 2001.

NASA Earth Observatory wrote: "On August 13, 2019, the Operational Land Imager on Landsat 8 took a natural picture of a giant pumice raft floating in the tropical Pacific Ocean near Late Island in the Kingdom of Tonga.

"The NASA satellite Terra discovered the mass of 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. "
