A new Pacific island breached the ocean surface in August 2006 from the eruption of a volcano in the Tonga island chain. Pumice stone floating on the surface was the first sign of an eruption. Gases trapped like bubbles in the magma cause the pumice, frothed volcanic glass, to be buoyant.

I took this photo yesterday of goose neck barnicles on the pumice which has taken all this time to reach the east coast of Australia. Our local radio alerted locals to the find.
