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.

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!

Telepresence on the R/V Sally Ride

From November 28 to December 5, 2016, the Inner Space Center (ISC) supported a science verification cruise for the R/V Sally Ride, one of two, new vessels in the U.S. Academic Research Fleet.  These short cruises are intended to test the ship, crew, and science systems to make sure that all are in proper working order before the ship  departs for its first research expedition. The Sally Ride was named after the late Sally Ride, the first American woman in space, who was part of the space shuttle Challenger crew in 1983.


The ISC team tested
the ship’s capabilities to support the Jason remotely operated vehicle (ROV) system as well as ship-to-shore telepresence technologies and protocols that will enable shore-based participation during ROV dives. Director of the ISC, Dr. Dwight Coleman, installed a mobile telepresence unit (MTU) on board. This unit allows for any ship to have telepresence capabilities.

ROV Jason deployed off the R/V Sally Ride.

During the cruise, ROV Jason was used for a variety of exploration activities. Geophysicist, Dr. Mark Zumberge, and his group from the Scripps Institution of Oceanography, used Jason to attach geophysical sensors to the sea floor. Dr. Lisa Levin, also from Scripps, used the ROV system to continue biological survey of the seafloor around the Del Mar methane seep near San Diego, CA.

Along with ROV operations, the R/V Sally Ride was able to connect to the Birch Aquarium. Amanda Netburn, Bruce Applegate, and Dwight Coleman hosted live  broadcasts to the aquarium’s new Sally Ride exhibit.

To Boldly Go… Ahyi Seamount

About 12.5 miles off the coast of Farallon de Pajaros, within the Mariana Trench Marine National Monument, lies the Ahyi Seamount, an active underwater volcano. This site remained unexplored until June 22nd, 2016, when the NOAA Ship Okeanos Explorer launched its remotely operated vehicles (ROVs) to investigate the volcano.

Deep Discoveries Are Getting Seirios

How little is known about our ocean is a fact many agree on, however scientists are actively working to bridge the gap between the unknown and discovery. Right now, the National Oceanic and Atmospheric Administration’s Office of Exploration and Research (NOAA OER) began the third cruise of their current research expedition. Aboard the NOAA ship Okeanos Explorer with remotely operated vehicles (ROVs) Deep Discoverer and Seirios, scientists are well on their way to meeting their goals for this trip. The area undergoing daily exploration is the Commonwealth of the Northern Mariana Islands (CNMI) and the Marianas Trench National Monument (MTMNM) in the western Pacific. The latter area is under NOAA’s protection, based on inferences that there may be unique features within its depths. Gathering baseline data and learning more about what these areas contain will enable effective conservation initiatives.
