Raft of Rubble

image

Captured by the Copernicus Sentinel-2 mission on Aug. 21, 2019, this image features a huge raft of pumice rock drifting in the Pacific Ocean. The pumice is believed to have come from an underwater volcano near Tonga, which erupted on Aug. 7.
The volcanic debris is full of holes and gas that make the rock light enough to float up to the sea surface. Covering a total area of around 150 square kilometers, this massive gathering of floating rocks has turned the ocean surface from its usual twinkling blue to a dull gray that almost looks like land.

The raft is drifting toward Australia, and while it may be causing some problems for sailors, it could bring benefits to the Great Barrier Reef. There are millions of pieces of rock, and each is a potential vehicle that offers a ride to small marine organisms such as algae, snails, barnacles and corals. If the raft eventually reaches Australia, the hope is that these hitch-hiking organisms could help replenish the Great Barrier Reef, which has been damaged by rising seawater temperatures.
