Fish on seafloor, Offshore Northern California
A kelp greenling fish swimming above a seafloor of mixed gravel, cobble and rock outcrop with scattered shell. Fish is approx. 20 cm (8 inches) long. Image acquired 1 km (0.62 miles) offshore Half Moon Bay, California at a depth of 14 meters (46 ft). Also in the image are encrusting sponges, red algae (seaweed), and orange cup corals.

Dome fountain over Fissure D vent of the Episode 58 eruption
(September 20, 2007, 05:00:03 to 09:00:03) As the Episode 58 lava channel developed, the upper end of the channel crusted over so that lava—extruding from the erupting fissure—flowed through a short tube before entering the channel.
