NOAA Ocean Explorer Podcast

Watch a NOAA video podcast on the Submarine Ring of Fire 2004 (SRoF'04) expedition to the Mariana Arc. Video taken by the ROPOS ROV at the edge of Brimstone Pit near the summit of NW Rota-1 submarine volcano, showed a burst of ash, sulfur, and small rocks from the crater. This type of activity has never before been witnessed and documented on a submarine volcano. Video courtesy of Submarine Ring of Fire 2004 Exploration, NOAA Vents Program, NOAA-OE.

View colorful highlights of deep-sea marine life from the Gulf of Alaska, including fan corals, vase sponges, basket stars and squid. This video comes from a NOAA Office of Ocean Exploration mission to study unexplored seamounts in the Gulf of Alaska. 13 dives were made in the titanium-hulled submersible Alvin to collect this fascinating video from more than 3000 feet below the surface of the sea.

Watch a NOAA video podcast on the Submarine Ring of Fire 2006 (SRoF'06) expedition to the Mariana Arc. While the pilots were trying to tend to a troublesome suction sampler at 560 meters (1840 feet), a large burst from the Brimstone Pit (which clearly has two side-by-side eruptive vents) almost engulfs the vehicle in an ash plume.

Watch a NOAA video podcast on the Submarine Ring of Fire 2006 (SRoF'06) expedition dive to the Mariana Arc, Daikoku submarine volcano. Molten sulfur and volcanic gases are bubbling out of a vent along the far wall of Sulfur Cauldron, keeping the partially-crusted surface of the pond undulating. Sometimes the heaving is so great that pieces of crust near the vent break off, tip on end, and are pulled downward by the convecting currents in the pond.

Watch a NOAA video podcast on the Submarine Ring of Fire 2006 (SRoF'06) return to the Mariana Arc, NW Rota-1 submarine volcano. This is the first time that glowing lava has ever been witnessed from a submarine volcanic eruption! In this case, the lava is rising in the vent so fast that a small glimpse of red glow can be seen intermittently before it crusts over or is blown apart. What a sight! Do you think the scientists were a little excited? Video courtesy of Submarine Ring of Fire 2006 Exploration, NOAA Vents Program, NOAA-OE.
