Ocean Exploration, “Olympic-Style”

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).

Another important expedition objective is to collect information about the ocean’s chemical and physical properties and associated biological communities. The Olympic Coast marks the northern reach of the California Current, which seasonally upwells deep, nutrient-rich waters nearshore.  This process supports the sanctuary’s highly productive ecosystem. Twenty-nine species of marine mammals reside in or migrate through sanctuary waters; the area provides critical nesting habitat for numerous seabird species; and the region is also among the most productive fish-growing habitats in the world.  However, due to ocean acidification (a continued decrease in the global ocean’s pH, caused by the uptake of carbon dioxide (CO2) from the atmosphere), the California Current is now also delivering low-pH, and often low-oxygen (hypoxic), waters to the region, which can negatively impact many marine species.  The Olympic Coast NMS is thus considered a “sentinel site” for ocean acidification.  Monitoring and research take place to enhance the understanding of natural and historical resources in the area and how they are changing, as well as provide and early warning capability to detect changes to the ecosystem itself.

In addition to its ecological richness, the Olympic Coast NMS sanctuary is also culturally and historically rich. Over 200 shipwrecks are documented in sanctuary waters!  The Makah, Quileute, and Hoh Tribes, as well as Quinault Nation, all have strong, historical ties to the region.  NOAA sanctuary staff work cooperatively with the tribes to strengthen sanctuary resources and respect the longstanding relationship of coastal Native Americans with the marine environment.

Live video from the Olympic Coast NMS expedition will be broadcast on the Nautilus Live and Inner Space Center websites.  ROV dives should start August 19, 2017!  For more information about this expedition and the Olympic Coast NMS, visit the Nautilus Live expedition webpage, and the Olympic Coast NMS website.

Tuning into the Musician Seamounts

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).

From August 8th through August 31st, 2017, the Okeanos Explorer will map the area using multibeam sonar technologies aboard the ship.   Operations will start and end in Honolulu, HI. The additional mapping data will assist in better understanding the geologic history of the seafloor in the remote Pacific Ocean.

During the second cruise, from September 6th through September 30th, 2017, the ROVs Deep Discoverer and Seirios will explore the waters around the Musician Seamounts. By observing the marine habitat and organisms in this area, scientists hope to learn more about life in the Pacific Ocean Basin and the composition of the ocean ecosystem of this region.

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.

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.

Wreck-ollections: U-Boat 166

Welcome to the second installment of the Inner Space Center’s ‘Wreck-ollections’, wherein we take a closer look at some of the fascinating shipwrecks we’ve visited or re-discovered.  This season has found us diving on a series of historical wrecks from WWII, and so we will go back to the beginning of the summer, to the wreck of U-boat 166.
