The Underwater World of Microbes (part 2). Sometimes, the lift-off mats break away completely from the benthos and float up to the underside of the ice. The mats which stay afloat all summer can continue to photosynthesize under the ice and may become frozen in the following winter. Their buoyancy is so delicate that a gentle bump of diver bubbles can knock them back down. I had to sneak up on this one to capture a photo :-)
