Pacific pumice raft
Back in 2012, we posted about a series of photos that were floating around the internet. The photos were taken from a yacht that had encountered what appeared to be a beach, stretching as far as the eye could see in the middle of the South Pacific. It turned out that what they were seeing was floating pumice, the volcanic rock formed when lava erupts underwater. With a bit more investigation, it appeared that the photos dated back to 2006. At around the same time, the New Zealand Navy reported a pumice raft covering an area of roughly 10,000 square miles.
Recently, the New York Times reported that a couple sailing in the Southwest Pacific encountered a similar pumice raft — a floating mass of volcanic rocks, with some boulders as large as basketballs, blanketing the ocean as far as their boat’s spotlight could illuminate.
