Amusing Monday: A new hydrothermal vent field discovered off West Coast

The location of an unknown hydrothermal vent system was predicted by researchers studying maps of the seafloor along the Gorda Ridge off the West Coast. Following those leads, a group of underwater explorers looked for and found the shimmering cauldron of superheated water.

The discovery, during this year’s Nautilus Expedition, took place about a week ago in an area about 75 miles offshore of the border between California and Oregon.

As operators dimmed the lights from their remotely operated vehicles, the sounds of excited scientists filled the mother ship’s control room, where observers watched a video screen providing glorious views of the emerging flow (first video on this page).

“It’s like an artist’s rendition of another planet,” tweeted volcanologist Shannon Kobs Nawotniak of Idaho State University, where her team figured out where to look for the vents using high-resolution sonar bathymetry. Researchers named it the Apollo Vent Field in honor of the 50th anniversary of the moon landing this year.

Check out more photos and videos on the Nautilus website, and learn more about the project in “The Alien Landscapes of the Apollo Vent Field.”

The out-of-this-world reference to another planet was not an accident, as NASA researchers are contemplating deep-sea explorations of other worlds. For example, space scientists would like to send an unmanned craft to Europa, the sixth moon of Jupiter, where they would drill down through ice up to five miles thick to reach a volcanically active ocean. On the ocean floor of Europa, they might find hydrothermal vents with the right warmth and minerals to support life — possibly similar to the microorganisms that began life on Earth.

This year’s Nautilus expedition involved a project known as SUBSEA, for Systematic Underwater Biogeochemical Science and Exploration Analog. The project, which ended about a week ago, is a partnership between the National Aeronautics and Space Administration, the National Oceanic and Atmospheric Administration and various academic research centers.

The Exploration Vessel (EV) Nautilus is a research platform equipped with two ROVs: the Hercules and the Argus. They are owned by Ocean Exploration Trust, founded in 2008 by Robert Ballad to explore the oceans.

Background on the SUBSEA mission is provided in a 26-minute video featuring lead scientists Darlene Lim of NASA’s Ames Research Center and Christopher German of Woods Hole Oceanographic Institution (second video).

Gulf of California

On an entirely separate expedition in February, scientists aboard the Research Vessel (RV) Falkor from Schmidt Ocean Institute discovered colorful towers of minerals up to 75 feet tall in the Gulf of California. These towers, along with a variety of sea creatures clinging to them, were not there during a previous expedition a decade ago.

“Astonishing is not strong enough of a word,” said Mandy Joye, a marine biologist at the University of Georgia who led the team that discovered the vents.

Check out the story “Deep-Sea Explorers Find Trippy, Rainbow-Colored Wonderland” by reporter Stephanie Pappas and the slideshow “Sea Life Thrives at Otherworldly Hydrothermal Vent System,” both in the online magazine “Live Science.”

Schmidt Ocean Institute, based in Palo Alto, Calif., is part of the Eric and Wendy Schmidt Network of Philanthropies. The institute owns the RV Falcone and supports its crew for teams of researchers from various institutions.

Coast of Oregon

The current expedition of the RV Falkor, led by Carolyn Ruppel of the U.S. Geological Survey, is studying methane seeps off the Oregon Coast. The cruise will add to ongoing knowledge about the hundreds of methane seeps that might become a significant contributor of greenhouse gas emissions.

Live video from the ROV SuBastian is available during operational periods. Click at the top of the “Live from RV Falkor” page to connect to the feed when it is available.

As I post this blog, the live feed is accessible (video below).

Nautilus submarine ‘can send your soul to the bottom’ — Bob Ballard

It is rather amazing to watch live video from a submarine creeping along along the bottom of the Pacific Ocean off the Oregon Coast, and I wanted to remind everyone that this is something they can experience right now via the Nautilus Live webfeed. The live commentary from the operators can be amusing at times, but I didn’t want to wait until Monday to let you know what’s going on.

Exploration Vessel Nautilus, with its remotely operated submarines Hercules and Argus, has been exploring deep-sea vents off Oregon the past few days, marking the beginning of a six-month expedition along the West Coast and around Hawaii. The ROVs were launched Sunday as the weather allowed, and the mother ship is now moving up the coast. I’ve embedded the video on this page, but more information and alternate channels are provided on the Nautilus homepage. One can also send questions to the research team.

Amusing Monday: Splendid underwater images from EV Nautilus

Exploration Vessel Nautilus has completed its journey north to the Olympic Coast National Marine Sanctuary, where the research team captured plenty of intriguing video, including a close look at the sunken submarine USS Bugara (first video below). All videos are best in full screen.

EV Nautilus, operated by Ocean Exploration Trust, conducts scientific research along the sea bottom throughout the world, specializing in biology, geology and archeology. Education is a major part of the effort, and school curricula are built around live and recorded telecasts from the ship. In addition, a select group of educators and students are invited to go on the expeditions each summer.

This year’s expedition began in May in California, where the ship took data for high-resolution maps of offshore areas never surveyed before. That was followed by an examination of the Cascadia Margin, a geologically active area off the Oregon Coast where the researchers identified bubbling seeps with multibeam sonar.

Dives using remotely operated vehicles began in June when the ship arrived off the Canadian Coast west of Vancouver Island. One dive, which went down to 2,200 meters, captured images of a hydrothermal vent, where water gets expelled after being superheated by the Earth’s magma. Watch the video saved on the Nautilus Facebook page. In another video, the temperature at one vent got so hot that the researchers found themselves cheering as the temperature at the probe kept going up.

I am easily amused, but I have to say that I was intrigued by a 9,000-year-old living reef made of glass sponges that was discovered off the coast of Galiano Island, British Columbia (second video this page).

One amusing video was created while watching a six-gill shark in the Channel Islands off California. Suddenly, a crab came into view carrying another crab (third video below). “It’s an Uber crab!” one researcher commented. “Is that lunch?” another wondered.

Another great shot from the Channel Islands showed a big ball of shimmering anchovies along with a select group of predators, including several fish, a six-gill shark and a sea lion. This video can be seen on the Nautilius Facebook page.

The examination of the submarine Bugara (first video on this page) occurred Aug. 25 off Cape Flattery in Olympic Coast National Marine Sanctuary. The event was live-streamed with commentary from scientists, archaeologists and historians, as well as veterans who served on the submarine. Bugara was built during World War II and later became the first American submarine to enter the Vietnam War after Congress passed the Gulf of Tonkin Resolution.

After its decommissioning in California, Bugara was being towed to Washington state to serve as a target for a new weapons system. On June 1, 1971, the submarine took on water during transit and sank to the bottom, where it has rested ever since. No injuries occurred during the incident. For historical details, go to Bugara.net, which was set up for former sailors and others associated with the submarine.

A longer 1.5-hour video of the Bugara inspection by ROV can be viewed on the Nautilus Facebook page. This is basically what was viewed online in real time by observers — including a group gathered at Naval Undersea Museum at Keyport.

Another interesting video shot in Olympic Coast National Marine Sanctuary shows a siphonophore, a colony of specialized organisms that work together to form a chain of individuals that together are capable of swimming, stinging, digesting and reproducing. Researchers working the 4-to-8-p.m. shift were able to observe more than their share of these interesting colonies, so the group became known as the “Siphono4-8” (video below).

Nautilus currently is moored in Astoria, Ore., where it is scheduled to begin the next leg of its expedition on Wednesday. The goal is to search near Oregon’s Heceta Bank for ancient coastal landscapes that may have been above sea level 21,000 to 15,000 years ago. More live sessions and archived video are planned.
