Imagine that. And we had nothing to do with it..

Still it does not supersede the damage that has been done nor
does it mean full recovery. Sorry, doom is still on the horizon and
those who destroy the earth will be destroyed.

Massive pumice 'raft' spotted in the Pacific could help replenish Great Barrier Reef
The 150 sq km field of floating rock was created by an underwater volcanic eruption near Tonga
A giant raft of pumice, which was spotted in the Pacific and is expected to make its way towards
Australia, could help the recovery of the Great Barrier Reef from its bleaching episode by restocking
millions of tiny marine organisms, including coral.
The pumice raft, which is about 150 sq km, was produced by an underwater volcano near Tonga. It
was first reported by Australian couple Michael Hoult and Larissa Brill, who were sailing a catamaran
to Fiji, on 16 August.
“We entered a total rock rubble slick made up of pumice stones from marble to basketball size,” the
couple said in a Facebook post.
“The waves were knocked back to almost calm and the boat was slowed to 1 knot. The rubble slick
went as far as we could see in the moonlight and with our spotlight.”
The yacht’s steering became temporarily jammed by rocks between rudders and hull, but they
managed to clear it and warn other vessels in the area.
Since then, the pair have been working with Queensland University of Technology geologist Scott
Bryan by providing pictures and samples of the volcanic rock.
Bryan said the raft will be the temporary home for billions of marine organisms. Marine life including
barnacles, corals, crabs, snails and worms will tag along as it travels toward Australia and become a
“potential mechanism for restocking the Great Barrier Reef”.
“Based on past pumice raft events we have studied over the last 20 years, it’s going to bring new
healthy corals and other reef dwellers to the Great Barrier Reef,” Bryan said.
Pumice forms when frothy molten rock cools rapidly and forms a lightweight bubble-rich rock that
can float. The pumice raft comes from an unnamed but only recently discovered underwater volcano
that satellite images reveal erupted about 7 August.
It should begin to hit Australian shores in about seven months’ time, passing by New Caledonia,
Vanuatu and reefs in the eastern Coral Sea along the way as coral begins to spawn.
“It’s the right timing. So it will be able to pick up corals and other reef building organisms, and then
bring them into the Great Barrier Reef,” Bryan said.
“Each piece of pumice is a rafting vehicle. It’s a home and a vehicle for marine organisms to attach
and hitch a ride across the deep ocean to get to Australia.”
