London, Aug 12 (): A mass of small volcanic rocks covering 10,000 sq miles (26,000 sq km) has been found floating off the coast of New Zealand. This cluster has been spotted drifting in the Pacific Ocean by a military aircraft, about 1,000 kilometres off the coast of New Zealand.
The witnesses of the Navy ship said that it resembled a polar ice shelf, was made up of lightweight pumice expelled from an underwater volcano. These golf-ball-sized pumice rocks are made from lava and water and are very lightweight.
Scientists believe that these rocks likely spewed up in an eruption by an underwater volcano (seamount) called Monowai, which has been active recently. It had no connection with the eruption of the onshore ash eruption this week of another volcano, Mount Tongariro.
However Officials confirm that these small rocks pose no danger to shipping. The rock is sitting two foot (half a metre) above the surface of the sea waves and lit up a brilliant while colour in the spotlight. It viewed exactly like the edge of an ice shelf.
These volcanic rocks float like the one off the coast of New Zealand play a big role in the evolution of life on Earth, because these floating rocks can travel across long stretches of ocean. They have been known to ferry fishes, plants, and colonies of microbes across oceans.
Naval Lt. Tim Oscar says it’s the “weirdest thing” he has seen in 18 years at sea. As far ahead as I could observe was a raft of pumice moving up and down with the swell.” He also said that the rocks look a brilliant white under a spotlight, like a giant ice shelf.
