Everett, Wash.-based OceanGate says it’ll build not just one, but two deep-sea submersibles capable of taking crews as far down as 6,000 meters (3.7 miles) beneath the ocean surface, into a zone of perpetual darkness.
The vessels will take advantage of the same carbon-fiber and titanium design that was pioneered for OceanGate’s Titan submersible, which was built for exploration of the Titanic shipwreck site, nearly 4,000 meters (2.4 miles) down.
Interest in the Titanic trips, which are due to begin next summer, is one of the factors behind the planned expansion of OceanGate’s fleet.
“Increasing demand for Titanic missions, deep-sea research and environmental supervision of deep-sea mining have further reinforced the business case for adding to our dive capacity,” OceanGate CEO Stockton Rush said Tuesday in a news release.
Based on a newly completed expedition, they’ll see a hulk that’s decomposing almost before their eyes.
That’s the word from members of a deep-ocean exploration team who visited the site, nearly 13,000 feet beneath the surface, during a 10-day expedition in late July and early August.
Team leaders included Caladan Oceanic explorer/pilot Victor Vescovo, Titanic historian Parks Stephenson and Rob McCallum of EYOS Expeditions. With the aid of a technical crew from Triton Submarines, they surveyed the wreck during a series of five dives in the DSSV Limiting Factor, a two-person Triton 36,000/2 submersible.
The exploration team captured 4K video footage of the wreck using cameras that were specially adapted for the bone-chilling, high-pressure environment of the deep. The imagery will be used in a forthcoming documentary film by Atlantic Productions – and transformed into photorealistic 3-D models of the Titanic site for augmented-reality and virtual-reality platforms.
Stephenson said he was shocked to see how the wreck has deteriorated. Salt corrosion, metal-eating bacteria and deep currents are contributing to the decay.
“The most shocking area of deterioration was the starboard side of the officer’s quarters, where the captain’s quarters were,” he said in a news release. “The captain’s bathtub is a favorite image among the Titanic enthusiasts, and that’s now gone. That whole deck house on that side is collapsing, taking with it the staterooms, and the deterioration is going to continue advancing.”
The voyages of the R/V Petrel, funded by the late Seattle billionaire Paul Allen, are the focus of a National Geographic documentary premiering on Aug. 12 – and as a prelude to the show, the leader of the Petrel team is talking about what it takes to find historic shipwrecks in the Pacific.
“Our missions have led to discovery of over 30 historically significant shipwrecks, diverse ecosystems and encounters with rare marine species,” Rob Kraft, Vulcan’s director of subsea operations, says in an online Q&A. “The environment we operate in brings inherent dangers, challenges and risk that most people will never experience.”
That all sounds like a natural fit for the next episode of “Drain the Oceans,” a National Geographic series that delves into what we’d find beneath the waves if the world’s oceans could magically disappear.
When you think of the crown jewels of the coral reefs, it’s hard not to think of Australia’s Great Barrier Reef — and now those jewels are on full display in the Allen Coral Atlas, one of the scientific legacies left behind by Microsoft co-founder Paul Allen.
OceanGate set a deep-diving record last week when a crew of four rode inside the Everett, Wash.-based company’s Titan submersible to the Titanic-level depth of 3,760 meters (12,336 feet) in the Bahamas.
The April 17 voyage, which served as a test run for this summer’s trips to the wreck of the Titanic, marked the first time a non-military submersible carried more than three people to that depth, OceanGate said.
“This dive was another important step toward deep-sea exploration to more people and places,” OceanGate CEO Stockton Rush, who served as Titan’s chief pilot for the trip, said today in a news release. “We are developing technologies and designing submersibles and infrastructure that is making underwater exploration more accessible than ever before.”
Chalk up another historic shipwreck discovery for the Petrel, the research vessel funded by the late Seattle billionaire Paul Allen: This time it’s the USS Hornet, the World War II aircraft carrier that was sunk by Japanese forces in 1942.
The Hornet is best-known as the launching point for the Doolittle Raid, the first airborne attack on the Japanese home islands after Pearl Harbor and the United States’ entry into the war. Led by U.S. Army Lt. Col. Jimmy Doolittle, the raid in April 1942 provided a boost to American morale and put Japan on alert about our covert air capabilities.
A wide-ranging shipwreck survey funded by Microsoft co-founder Paul Allen is continuing after his death, and the latest discovery focuses on the Japanese battleship Hiei, which sank in the South Pacific during the Battle of Guadalcanal in 1942.
Warming oceans and an infectious wasting disease have combined to devastate what was once an abundant type of sea stars along the West Coast, scientists say in a newly published study.
Except for one unfortunate battery-powered drone, that is.
“The one that hasn’t come back, it could be any number of things,” said Jason Gobat, a senior principal oceanographer at the University of Washington’s Applied Physics Laboratory. Maybe something broke, or maybe it got stuck in the silt at the bottom of the sea.
The good news is that two other Seaglider drones are continuing to transmit data via satellite. Four free-floating EM-APEX probes have been heard from as well.
The experiment, supported with nearly $2 million in funding from Seattle’s Paul G. Allen Philanthropies, has shown that the robots can use acoustic signals to navigate their way under the ice shelf, monitor the water that flows into and out of the ice shelf’s subsurface cavity, and keep operating for a whole year.
Scientists say rapidly warming oceans played a key role in the world’s biggest mass extinction, 252 million years ago, and could point to the risks that lie ahead in an era of similarly rapid climate change.
The latest analysis, published in this week’s issue of the journal Science, puts together computer modeling of ancient ocean conditions and a close look at species characteristics to fit new pieces into a longstanding puzzle: What were the factors behind the Permian-Triassic mass extinction, also known as the Great Dying?
