Days later, Australian sailors heading to Vanatou on a ROAM catamaran said they encountered volcanic rocks "made up of marble pumice stone to the size of a basketball so no water could be seen."  The crew of ROAM Michael and Larissa Holt told CNN that they had been at sea for 10 days before coming into contact with the gray floating matter one evening.
"It was actually quite ominous," Larissa said. "The whole ocean was dull – we couldn't see the reflection of the water of the moon."
"The rocks somehow closed around us, so we couldn't even see our wake or wake. he could just see the edge where he returns to plain water ̵
" It was a little mystery, we didn't know how deep it was. if we were sailing over a volcano that was active at that moment. It looked like it was coming up more, bubbling underneath, "Larissa said.
The pumice stone, which is filled with holes and cavities, floats like an iceberg, with about 90% under water and 10% above water, the couple explained.
This pumice stone is expected to move downstream to the Australian coast over the next 7-10 months, they said, where scientists believe it can have a positive effect on the microorganisms there.
This is because floating stones can act as a home for a nest of marine organisms.
As the pumice stone travels to the Great Barrier Reef, the marine life attached to it will also travel, potentially bringing in a variety of new colonies of bananas, corals, and more.
The eruption this month could have similar positive effects, Brian said.
