Welcome to the NOAA Ship Okeanos Explorer Gulf of Mexico 2017 expedition! The team will be exploring the Gulf of Mexico from November 29 – December 21, 2017, using multibeam sonar and the remotely operated vehicle (ROV), Deep Discoverer, to explore the seafloor. The 23-day expedition will focus on acquiring data on priority exploration areas identified by ocean management and scientific communities. Tune in to the live streams and explore with us!
Despite being frequently encountered by scientists aboard the NOAA Ship Okeanos Explorer, E/V Nautilus, and other exploration vessels, much is left to learn about corals and sponges. Both are sessile (non-moving) organisms, serve as vital resources for other marine life, and can indicate the health of oceanic ecosystems. Learn more about these fascinating animals below!
Corals exhibit some plant-like characteristics, but are actually animal relatives of jellyfish and anemones. They are all within the phylum Cnidaria. All corals are classified as either “hard corals” or “soft corals”. Hard corals have a limestone skeleton, and make up the foundation of a coral reef. They can take a rounded, branching, or flat appearance. Soft corals bind together on a softer structure, and can take the shapes of whips, spirals, and trees. Hard corals can grow as much as ten centimeters per year, the same rate of growth as human hair, but most only grow up to three centimeters each year. Soft corals grow at a rate of two to four centimeters per year. When a coral reef is damaged by a storm, pollution, or by other factors, it may take a significant amount of time before it is able to recover and grow to its former size.
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→
From August 18, 2017, to September 3, 2017, the E/V Nautilus will be exploring the Olympic Coast National Marine Sanctuary (NMS), located along the Olympic Peninsula of Washington state. The sanctuary encompasses 3,189 square miles (8,260 km2), an area equivalent to the states of Delaware and Rhode Island combined. It extends 25 to 50 miles (40 to 80 km) from the shore, including most of the continental shelf, as well as three important submarine canyons: the Nitinat Canyon, the Quinault Canyon and the Juan de Fuca Canyon. The main objectives of this expedition are to explore and characterize seafloor resources and features associated with these submarine canyons. Quinault and Quileute Canyons have never been explored by remotely operated vehicle (ROV) or autonomous underwater vehicle ( AUV).
During their 2015 Hohonu Moana expedition, the NOAA Ship Okeanos Explorer discovered and mapped an unnamed seamount in the Central Pacific Ocean Basin (shown in the image above). The ship and scientists are now returning to this region, “Musician Seamounts”, to conduct additional mapping and remotely operated vehicle (ROV) operations over two consecutive cruises. These efforts will be focused north of the Hawaiian Islands, close to the Papahānaumokuākea Marine National Monument (PMNM).
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. Continue reading 2016 – A Year in Review→
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!
