Sailors Find Pumice 'Raft' Floating in Pacific that Could Help Restore Great Barrier Reef
A huge raft of pumice created by an underwater volcano is floating toward Australia, and it could help the Great Barrier Reef recover from bleaching.
The pumice raft is about 60 square miles almost as big as Washington D.C. Scientists say it was formed earlier this month by an underwater volcano near Tonga, some 2,000 miles east of Brisbane, Australia, in the South Pacific Ocean.
As lava spewed from the volcano, it cooled into pumice stone, which is full of holes and can easily float, according to NASA.
Sailors first encountered the giant stone raft on Aug. 9, according to the Smithsonian Institutions Global Volcanism Program. The purser on a small ship reported being surrounded by pumice as far as she could see. She said the surface was about a foot deep and contained pieces larger than 30 inches in diameter.
