Weekend Discoveries

This weekend the NOAA Ship Okeanos Explorer visited Shostakovich Seamount, and began its “Water Column Wonderland” week. Check out some of the unique creatures that live beneath the sea with imagery captured by remotely operated vehicle (ROV) Deep Discoverer! Continue reading Weekend Discoveries

The Scintillating Sea Life of Pao Pao Seamount

The NOAA Ship Okeanos Explorer had an amazing dive March 9, 2017 on Pao Pao Seamount, an underwater mountain in the Tokelau Seamount Chain in the South Pacific. Continue reading The Scintillating Sea Life of Pao Pao Seamount

2016 – A Year in Review

It’s been another eventful year here at the Inner Space Center (ISC)! We outfitted two research vessels and a merchant vessel with telepresence technologies, and supported over 100 days of telepresence on the E/V Nautilus, and on the NOAA Ship Okeanos Explorer. Our services facilitated the investigation the El Faro shipwreck, supported a 5-year study of submerged tribal cultural sites in Rhode Island Sound, and enabled the first ever telepresence broadcast from a manned submarine! During the summer, we hosted the next generation of deep-sea scientists at ISC Mission Control as they participated in a Woods Hole Oceanographic Institution (WHOI) dive-planning boot-camp. Meanwhile, the Nautilus and Okeanos Explorer continued their ground-breaking deep sea explorations of offshore California, and the Marianas region.

Okeanos Explorer Dives on Pearl Harbor Mini Subs

On December 7th, 2016, the NOAA Ship Okeanos Explorer dove on two Japanese mini-subs that sank 75 years earlier, during the attack on Pearl Harbor. The USS Ward fired the first shot of the Pacific War, sinking this submarine 90 minutes before the air raid on Pearl Harbor. This attack marked the introduction of the United States into World War 2. Highlights from the dives on these submarines can be viewed below:

More photos and illustrations of the mini-subs and the USS Ward are available on the National Marine Sanctuaries website.

Be sure to check for updates on the upcoming field season on the Okeanos Explorer Home Page, the Nautilus Live Homepage, the Inner Space Center website, and on our Facebook and Twitter pages!

Cool highlights  from the 2016 field season (like this ghost catshark) are available on our YouTube channel!

New Year, New Field Season!

The NOAA Ship Okeanos Explorer‘s 2017 field season will kick off January 18, 2017, with a mapping expedition from Honolulu, Hawaii, to Pago Pago, American Samoa. This field season marks the third year of CAPSTONE, the Campaign to Address Pacific Monument Science, Technology, and Ocean Needs. The goal of which project is to collect data necessary to support science-based decision making for marine protected areas (MPAs) in the central and western Pacific. Continue reading New Year, New Field Season!

Discoveries from Leg 3 of the Okeanos Explorer’s EX1605 Expedition

Completed on July 10th, leg three of the NOAA Ship Okeanos Explorer‘s EX1605 expedition was chock-full of discoveries. The Okeanos‘s remotely operated vehicles (ROVs) conducted 22 dives, exploring many recently-mapped sites in the Mariana Trench Marine National Monument (MTMNM). They ventured where no ROVs have dove before.

Ship-based sonar mapping, along with ROV imaging and rock sampling, revealed new hydrothermal vent sites, deep-water coral reefs, the first petit-spot volcano found in US waters, and a new mud volcano in the MTMNM.

Amid the geological findings, biologists cataloged many new species. The pictures and videos below highlight some of the newly-discovered inner-space aliens (strange alien-looking creatures) from leg three of the Okeanos Explorer‘s EX1605 expedition.

This cusk eel, found at Unnamed Forearc on June 28th, 2016, was among the first new species discovered during this leg of the expedition.

 

This ghost-like fish, dubbed “Casper” by land-based scientists, is a species in the fish family Aphonoidae. Until June 30th, 2016, when the ROVs came across Casper, no fish in this family have ever been seen alive.

After a long geology-based dive, the ROVs came upon this undescribed species of Pachycara, commonly called eelpout.

  The scientists wished they had enough time to collect this new species of hard sponge that they discovered on July 6, 2016.

But, they were able to collect this new species of stalked glass sponge!

For more ocean exploration and discoveries be sure to check out the Nautilus Live website for updates from the E/V Nautilus! Situated of  the California coast, the Nautilus is currently (pun intended) mapping and conducting dives off the Channel Islands.

The Okeanos won’t be diving again until June 27th, 2016. Until then, check out dive highlights on our YouTube channel, and the NOAA Ocean Explorer YouTube channel! For more details about individual dives from the NOAA Ship Okeanos Explorer visit the NOAA Okeanos Explorer website.

What is an ROV?

If the ocean is so unfathomably wide and deep, how can scientists possibly hope to do any more than dip our noses beneath the waves to explore? Luckily, engineers have adapted machines to reach areas of the ocean that would never be possible with a human alone. This is where remotely operated vehicles, or ROVs, become essential tools of discovery.

To use an ROV, three pieces of technology are crucial. The first is the ship. This is where the scientists are conducting their research, and where the ROV pilot maneuvers the vehicle. The second piece is the tow sled. This piece of technology is used to absorb all of the movement associated with waves and currents, allowing the ROV to be stable. Lastly, is the ROV itself. The ROV and sled are tethered to their research vessel via fiber optic cabling. Through this system, the pilot can maneuver the ROV safely from the ship.

ROVs are designed to withstand the extreme cold and pressure of the deep ocean without malfunction. They are typically either colored yellow or white to stand out against the blues of the ocean, and are built out of materials that are resistant to many atmospheres of compression. ROVs are also balanced with the dense components on the underside, and the flotation portion on top, to offer more stability as it traverses the deep ocean. ROVs can also be equipped with a variety of tools to help them explore efficiently. Since the ocean continually gets darker the deeper one goes, all ROVs are equipped with extremely bright lights. Each ROV has a few high definition cameras that allows us to watch the ROV. They also have two lasers that are used for scale, generally they are 10 cm apart. Most vehicles have biofeedback manipulator arms that are used to gather samples. Some vehicles have a sample box to take bring samples up to the surface for more research.

These incredible machines are vital for scientists to explore parts of the ocean that would not otherwise be seen by human eyes. Tune into the live video feeds below to see ROVs in action, along with more exciting content!

Introducing the Newest U.S. Academic Research Vessel: R/V Sally Ride

Named in honor of the first woman to travel into space, Dr. Sally K. Ride, the R/V Sally Ride is the newest of the United State’s Academic Research Vessels (UNOLS).  Operated by the Scripps Institution of Oceanography at the University of California, San Diego, in cooperation with the Office of Naval Research (ONR), Sally Ride represents the new Ocean Class of research vessels. The 238-foot ship features seafloor mapping systems, doppler radar for mapping deep water currents, 2,035 square feet of lab space, and telepresence technologies.
