“Studying these corals can help us understand how they survive for such long periods of time, as well as how they may respond to climate change in the future,” said Dunbar.
Among the other findings were a five-foot tall yellow bamboo coral tree that had never been described before, new beds of living deepwater coral and sponges, and a giant sponge scientists dubbed the “cauldron sponge,” approximately three feet tall and three feet across. Scientists collected two other sponges which have not yet been analyzed, but may represent new species or genera as well.
The mission also discovered a “coral graveyard” covering about 10,000 square feet on a seamount’s summit, more than 2,000 feet deep. Scientists estimated the death of the community occurred several thousand to potentially more than a million years ago, but did not know why the community died. The species of coral had never been recorded in Hawaii before, according a Smithsonian Institution coral expert they consulted.
Finding new species was not an express purpose of the research mission, but Dunbar and Christopher Kelley, a scientist with the University of Hawaii, both collected specimens that looked unusual. Kelley’s objective was to locate and predict locations of high density deep-sea coral beds in the Monument. NOAA scientist Frank Parrish also led a portion of the mission, focusing on growth rates of deep-sea corals.
The three-week research mission ended in November 2007, but analysis of specimens is ongoing. “The potential for more discoveries is high, but these deep-sea corals are not protected everywhere as they are here, and can easily be destroyed,” said Kelley.
The Papahânaumokuâkea Marine National Monument has more deep water than any other U.S. protected area, with more than 98 percent below SCUBA-diving depths and only accessible to submersibles. The Hawaii Undersea Research Laboratory, sponsored by NOAA and the University of Hawaii, piloted the Pisces V submersible from a research vessel to the discovery sites, between 1,148 and 5,823 feet deep.
Funding for the mission was provided by NOAA through the Papahânaumokuâkea Marine National Monument and NOAA’s Office of Ocean Exploration and Research. Identification of the corals was provided by Les Watling at the University of Hawaii.
The Papahânaumokuâkea Marine National Monument is administered jointly by the Department of Commerce, Department of the Interior, and the State of Hawaii and represents a cooperative conservation approach to protecting the entire ecosystem.
NOAA’s Office of Ocean Exploration explores the Earth’s largely unknown ocean for the purpose of discovery and the advancement of knowledge, using state-of-the-art technologies.
NOAA understands and predicts changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and conserves and manages our coastal and marine resources.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
