World’s First 3D Shipwreck Mapping Website

June 28, 2017 | 0 Comments

The University of California San Diego, Bermuda’s Ministry of the Environment, and LookBermuda have officially launched a first-of-its-kind effort to scan underwater shipwrecks and reefs in three dimensions and at an unprecedented level of detail, all while making the 3D environments accessible online to viewers worldwide.

The project, called the Bermuda 100 Challenge, pushes the frontiers of engineering technology and showcases the fascinating marine history and beauty of Bermuda’s underwater landscape.

The Bermuda 100 website at Bermuda100.com presents as “an exciting conservation, research and educational outreach programme.”

A spokesperson said, “Visitors to the America’s Cup Village in Bermuda this spring were among the first to experience the technology in action, where it will remain through to the end of the Cup for the thousands of daily fans.

“In partnership with America’s Cup Endeavor educational programme two large 3D digital displays in the education pavilion allow students and visitors to virtually fly between shipwrecks and dive below the ocean surface to visit the four initial wreck sites.”

“Now anyone can virtually “dive” Bermuda’s culturally and historically significant wrecks from anywhere in the world. The goal is to map 100 wrecks and sites of natural beauty and significant ecological importance. The data will be used by marine scientists, historians, students, archaeologists and conservationists to monitor the wrecks and reef over time.”

“It’s like having a massive, passive sensor network, precisely capturing longitude, latitude, depth and color of each underwater site,” said Dr. Falko Kuester, a computer scientist and structural engineer from the University of California San Diego, who spearheaded the digital mapping effort.

“The data provide a baseline of as-is conditions that will allow scientists to study changes such as deterioration, sediment transport and coral growth.”

“The project was initiated when Jean-Pierre Rouja, a filmmaker and founder of LookBermuda and the Nonsuch Expeditions, and Dr. Philippe Rouja, Principal Scientist of Marine Heritage and Ocean Human Health and Custodian of Historic Wrecks for the Department of Conservation Services, connected with Dr. Kuester and his team from UC San Diego’s Cultural Heritage Engineering Initiative [CHEI].

“The result was the perfect combination of photography, shipwrecks and computer science that turned 2D photographs into 3D models.”

“This is a perfect example of our ongoing efforts to combine high-quality media with the latest disruptive technologies for cultural preservation, conservation, exploration and education, whilst partnering with experts in their respective fields,” said LookBermuda’s Jean-Pierre Rouja.

“This project allows scientists, students and the public at large to view, interact with and ultimately better appreciate these otherwise hard-to-access resources. It follows the huge success of the 2017 CahowCam which through a boost from a similar relationship with the Cornell Lab of Ornithology this season streamed close to 10 million minutes of video.”

“It is now possible to experience Bermuda from the sky, dip below the surface to virtually explore the wrecks of the Montana and the Blanche King, swim to the Manilla while digitally labeling, extracting and evaluating its cannons, before traversing the wreck of the Mary Celestia,” said UC San Diego’s Kuester.

“With the point-based visual analytics techniques developed by our team, it is possible to literally deep-dive into the existing four shipwrecks, accurately referenced within a 3D model of the island of Bermuda and its surrounding reefs. That said, this is one case where it is better experienced than described.”

“Bermuda has been at the centre of Atlantic commerce for over 400 years. Dr. Philippe Rouja said, “The four wrecks featured in the website are just a small portion of the wrecks around Bermuda but have been carefully chosen by the Historic Wrecks Authority for their aesthetic value, their historic significance and their diver-friendly aspects.

“The Department of Environment and Natural Resources needs to be commended for creating strong scientific partnerships that allow us to manage Bermuda’s abundant natural and cultural resources.”

Fundamentally, he added, “the richer the stories we can tell and the more engaging and interconnected we can make our heritage, the easier it will be to preserve and manage it for future generations.”

“For Bermuda’s Custodian of Historic Wrecks, the site could generate new enthusiasts. “For example, without the limits of a mask, tank and fins, we can share an image of an underwater airplane engine with plane enthusiasts and engineers and generate interest from sectors far beyond the diving fraternity,” said Dr. Rouja.

“We have plans to create models of some of the more unique elements of our wreck sites— sites that are not open to the public— so the online community can give us the benefit of professional insights. For those who cannot travel or cannot dive, the 3D virtual experience is of particular value.”

“According to UC San Diego’s Kuester, the Bermuda 100 could become the foundation for a global atlas of shipwreck sites and coral reefs on a global scale.”

“It would allow scientists, stakeholders and the public alike to explore and better understand these unique ecosystems, and contribute towards their preservation,” he explained.

“This project pushes the envelope of science, technology and engineering in the context of robotic sensor platforms, imaging systems, 3D modeling, visualization and interactive data exploration.”

“To date, over four billion data points have been seamlessly stitched together using the latest technology to make a complete ‘virtual reality’ experience.

“The interactive 3D model of Bermuda’s waters and four initial wreck sites has been built from tens of thousands of photographs, and, unlike a video, can be fully manipulated – allowing the viewer to navigate any site in every direction at their own pace. As additional shipwrecks are scanned, the overall data set will increase dramatically.”

“Dealing with so much data is a huge technical challenge in order to keep the viewer’s experience easy and fluid. The 4.3 billion data points have to be rendered and displayed 30 times every second, which means processing 133 billion data points per second.

“Further, if 3D goggles are involved, where data for the left and right eyes are rendered separately, the total data points doubles to 266 billion.”

Robert Steinhoff, Chairman of the Historic Wrecks Authority said, “Strong international partnerships in marine heritage and marine science have resulted in our small community taking bold and important, internationally recognised conservation steps. Shipwrecks in Bermuda continue to have an important role to play in marine conservation – not least in attracting people into the ocean space.

“Bermuda’s exciting shipwrecks invite the world diving community to visit Bermuda and experience it in person while the partnership with UC San Diego will be a testbed for advanced virtual imaging technology that allows us to share our underwater museum with the world—and hopefully inspire a new generation of cultural and natural conservationists.”

“The continued stewardship of Bermuda’s wrecks sites is vitally important. Many wreck diving sites have dedicated mooring buoys installed and maintained through the generous long-term commitment of the Stempel Foundation to make access easier and protect the wrecks from anchor damage.

“These protected areas are also no-fishing sites. Diving these wreck sites is the highlight for many visitors to Bermuda and makes a substantial contribution to the tourism economy.

“While the world’s attention has been on the cutting-edge technology of America’s Cup boats flying on the Great Sound, it is fitting that technology now allows anyone with an Internet connection to fly around and dive underwater to tour shipwrecks that lie quietly beneath Bermuda’s turquoise water.”
