A strange sight in the South Pacific

I thought this was incredible and worth posting.

In August 2006 the yacht "Maiken" was travelling in the South Pacific when they came accross this. It looks like the beach, but is actually sand floating on top of the water.

It was apparently caused by a volcanic erruption as you can see from the pictures.

Probably granular pumice. Foam rock that floats on water; like the thing for rubbing off hard skin.

Yep, it looks like pumice. I've never seen it out at sea like that! Volcanic regions are always interesting. I took this in Iceland last Summer.
