NOAA Ship Okeanos Explorer: Galápagos Rift, New Hydrothermal Vent Discovered Aug 02, 2011

Nine ROV dives into the Galapágos Rift 2011 Expedition, the science team finally discovered the type of hydrothermal vent community they had been searching for. Clusters of tube worms, limpets, mussels, and anemones were seen to inhabit cracks in the lava bed where mineral-rich, geothermally-heated water 'vents' out. Two species of tube worms were found in abundance: the giant Riftia pachyptila and also the much smaller, never before observed in the Galápagos, Tevnia jerichonana. Brachyuran crabs, vent shrimp, and scale worms clung not only to the surrounding rock but also to the tube worms themselves in some cases. Extensive fields of dead and living clams surrounded the individual pockets of venting. Video courtesy of NOAA Okeanos Explorer Program, Galapágos Rift Expedition 2011.

NOAA Ship Okeanos Explorer: Mendocino Ridge 4,600ft Gas Plume Discovery Nov 02, 2024

Mendocino Ridge 4,600ft gas plume discovery off the California coast. Okeanos Explorer, "America's Ship for Ocean Exploration", is equipped with the latest in technology systems, including multibeam sonar. This technology involves sending beams of sonar to the ocean floor and measuring the amount of time it takes for those beams to bounce back to the ship. In doing so, the sonar creates a 3-D "sound picture", or map, of the seafloor. While the ship was testing its sonar off the coast of California, the sound waves bounced off gas in the water column, creating a remarkable image of a gas plume that rose 4,600 feet from the seafloor. A landslide area at the base of the plume has led some scientists to believe that the plume might be methane, released by the landslide from methane hydrates. Okeanos Explorer is preparing to explore the waters north of Indonesia in the summer of 2010, in collaboration with Indonesia. The ship will continue to explore the western Pacific in 2011.

Northeast Lau Response Cruise (NELRC) 2009: Spectacular West Mata Eruptions May 13, 2009

Scientists funded by NOAA and the National Science Foundation recorded the deepest erupting volcano yet discovered, describing high-definition video of the undersea eruption as spectacular. Eruption of the West Mata volcano, discovered in May 2009, occurred nearly 4,000 feet below the surface of the Pacific Ocean, in an area bounded by Fiji, Tonga and Samoa. We found a type of lava never before seen erupting from an active volcano, and for the first time observed molten lava flowing across the deep-ocean seafloor, said the missions Chief Scientist Joseph Resing, a chemical oceanographer at the University of Washington who collaborates with NOAA through the Joint Institute for the Study of the Atmosphere and Ocean. Though NOAA and partners discovered a much shallower eruption in 2004 in the Mariana Arc, the deeper we get, the closer the eruption is to those that formed most of the oceanic crust. This spectacular sequence is a close view of the eruption with violent magma degassing events producing bright flashes of hot magma. Lava is blown up into the water before settling back to the seafloor, and large plugs of lava flow rapidly down the slope. In the foreground is the front of the Jason remotely-operated vehicle (ROV) with sampling hoses. The area in view is about 6-10 feet across in an eruptive area approximately 100 yards that runs along the summit.

RMS Titanic Expedition 2004 Dec 18, 2007

Breathtaking... Nearly 20 years after first finding the sunken remains of the R.M.S. Titanic, marine explorer Robert Ballard returned in June 2004 helped by the National Oceanic and Atmospheric Administration (NOAA), Office of Ocean Exploration to study the ship's rapid deterioration. The team worked aboard the NOAA Ship Ronald H. Brown from May 30 through June 9 spending 11 days at the wreck site, mapping the ship and conducting scientific analysis of its deterioration. Using the Institute for Exploration (IFE) remotely operated vehicles (ROV's) Hercules and Argus, to conduct a sophisticated documentation of the state of Titanic was not possible in the 1980's. This "Look, don't touch" mission utilized high-definition video and stereoscopic still images to provide an updated assessment of the wreck site at an enormous depth of 3,840 meters (12,600 feet). As the nation's ocean agency, NOAA has a vested interest in the scientific and cultural aspects of the Titanic, and in its appropriate treatment and preservation. NOAA's focus is to build a baseline of scientific information from which we can measure the shipwreck's processes and deterioration, and then apply the knowledge we gain to other deep-water shipwrecks and submerged cultural resources.

Submarine Ring of Fire 2004: NW Eifuku Volcano, Extraordinary Champagne Vent Jul 20, 2007

Watch a NOAA video podcast on the Submarine Ring of Fire 2004 (SRoF'04) expedition to the Mariana Arc. This movie shows the discovery of the Champagne vent at northwest Eifuku volcano, where bubbles of liquid carbon dioxide are actively venting from sea-floor hot springs. This unusual phenomenon is due to the fact that the emissions from NW Eifuku volcano are particularly gas-rich. The high pressure at this depth keeps the carbon dioxide in a liquid state. Scientist discovered th Champagne vent at a depth of 1,607 meters (5272 feet more than 1 mile deep). Video courtesy of Submarine Ring of Fire 2004 Exploration, NOAA Vents Program, NOAA-OE.

Tracking Narwhals in Greenland 2006-2007 Apr 23, 2007

In the frigid waters off the coast of Greenland scientists are getting valuable data from narwhals - the most ice loving whales in the world. Narwhals, beluga and bowhead whales, which you can hear in the background, make their homes in the Arctic. There are about 100,000 narwhals in the world, and the vast majority of them - about 50,000 to 70,000 - live in the Arctic waters of Greenland.

The Hidden Ocean, Arctic 2005: Experience Under-Ice Diving Mar 12, 2007

While much of under-ice diving is similar to regular diving, there are a few important differences. First, the divers wear drysuits instead of wetsuits. These dry suits are sealed at the wrist and the neck and don't let any water in beyond the seals. Second, under-ice diving is usually performed using compressed air, not other mixed gases and the regulators used are specifically designed to be used in temperatures below freezing. Most different from regular diving operations, under-ice divers are tethered to the surface. Video footage courtesy of Shawn Harper, The Hidden Ocean, Arctic 2005 Exploration, NOAA-OE.

Vailulu'u 2005: Nafanua Submarine Volcano "Eel City" Mar 12, 2007

The Crevices at 708 meters (2323 feet) of a hydrothermal vent site are occupied by thriving aggregations of cutthroat (synaphobranchid) eels. These eels, which have now been identified as Dysommina rugosa, are known from trawl samples in both the Atlantic and Pacific oceans, but have never before been studied in their natural habitat. The only common metazoan (multicellular) animals occupying these low-temperature hydrothermal vents, preliminary work indicates that they use the vent only as a place to live. They seem to feed not on chemosynthetic bacteria, but on crustaceans that pass by Nafanua’s summit in the currents. Video footage courtesy of UCSB, Univ. S. Carolina, WHOI, NOAA-OE.
