Pumice ... manna from heaven :)

Recycling and replenishment, just two of the ways nature continues to remain forever mysterious to us rubes continue unabated. This time, it's a huge floating raft of pumice generated by an underwater volcano floating toward Australia, bringing needed nourishment to the Great Coral Reef.

A gigantic fleet of floating rocks, spewed up from an underwater volcano in the Pacific Ocean, floated across the waves for thousands of miles. Eventually, it made it all the way to Australia, then started on a new project: revitalising the world's largest (and very threatened) coral reef system.

It gets better.

Each one of these small rocks attracts marine organisms, including algae, barnacles, corals, and more. These tiny travellers end up hitching a ride across the ocean, and they can help seed and replenish endangered coral systems at their ultimate destination: for many, the Great Barrier Reef.

"Each piece of pumice has its own little community that has been transported across the world's oceans – and we have had trillions of pieces of this pumice floating out there following the eruption," says geologist Scott Bryan from the Queensland University of Technology in Australia.

"Each piece of pumice is a home, and a vehicle for an organism, and it's just tremendous. The sheer numbers of individuals and this diversity of species is being transported thousands of kilometres in only a matter of months is really quite phenomenal."

Manna indeed. :)
