New species of deep-sea corals discovered in Atlantic Marine Monument

DNA analysis recently confirmed that Woods Hole Oceanographic Institution (WHOI) scientists and their collaborators at OceanX, the University of Connecticut (UConn), and NASA’s Jet Propulsion Laboratory (JPL) discovered two new species of deep-sea corals during a September 2018 expedition in the Northeast Canyons and Seamounts National Monument, located about 100 miles from the Northeast U.S. coast.
The research team was led by deep-sea biologist Tim Shank of WHOI and included co-PIs Taylor Heyl (WHOI), Rachel O’Neill (UConn), and John Leichty (JPL). Utilizing OceanX’s research and exploration vessel Alucia, the team explored and surveyed several of the unique deep-sea habitats in the monument, which includes three underwater canyons deeper than the Grand Canyon.

During the two-week expedition, the scientists collected a total of 29 coral samples in Lydonia Canyon at depths between 369 meters (1,211 feet) and 903 meters (2,963 feet) using the submarine Nadir. These were the first human-occupied submersible dives in this canyon since 1982 and only the third deep-submergence mission to Lydonia Canyon.
“Through ongoing genetic barcoding, we have identified at least two corals so far that represent genetically different species,” Shank said. “They don’t show sufficient genetic similarity to be any species that is currently known in the world’s repository for DNA sequences.”
According to Heyl, the two likely new species found in Lydonia Canyon are bubblegum corals, which she described as soft, deep-water corals, “with bundles of polyps that resemble wads of bubblegum along their branches.”
“We didn’t expect to find bubblegum corals there at all, since they haven’t been found in any of the neighboring canyons,” Shank said. “We found pink, red, and white bubblegum corals thriving there.”

“We observed a high diversity of other corals—at least 24 species—on the seafloor and are discovering more through genetic analyses,” he added.
Shank noted that coral species deep in the canyon at more than 900 meters (2,953 feet) below the surface were very different from those found in shallower waters. In total, the team collected some 200 samples of corals, sponges, and other marine life during the expedition’s three submersible dives.
“We’re still analyzing the data,” he noted. “But we found surprising patterns of species diversity at different depths and among the different canyons in the monument.”
Corals found at these depths grow at an extremely slow pace: One that is a foot tall could be as much as 500 years old. Deep-water corals around the world also provide the framework to support entire ecosystems that contain more than 2,500 species living on and around them, including brittle stars, squat lobster crabs, and sea lily crinoids.

In addition, the team tested a new universal barcode for invertebrates during the expedition. Barcoding is a technique that uses a specific segment of an organism’s DNA to identify different species at the genetic level, rather than by analyzing an organisms physical characteristics. UConn’s O’Neill and her team were able to validate the effectiveness of the new barcode by distinguishing all of the different salp species present in a single, commingled sample. Salps are a gelatinous, free-swimming animal common to the open ocean that may play an important role in Earth’s climate system by consuming carbon near the surface and excreting it in pellets that sink into the deep ocean.

The Northeast Canyons and Seamounts National Monument covers approximately 4,913 square miles (12,724 square kilometers), is located about 130 miles east-southeast of Cape Cod, and includes two distinct areas: one that covers three canyons and one that covers four seamounts. (Map courtesy of NOAA)
The monument was created by President Barack Obama in 2016 and is the first and only national marine monument in the Atlantic Ocean. However, it is currently under threat of losing its protected status.
“The Northeast Canyons represent some of the most unique and biodiverse habitats in the Atlantic Ocean, and exploring and understanding these canyons is critical to creating awareness for and protecting them,” said Vincent Pieribone, Vice Chairman, OceanX. “We are thrilled to learn with our partners at WHOI, JPL, UConn and Bloomberg Philanthropies that this mission uncovered new species of coral. These discoveries will help move us toward a better understanding of our oceans, our planet’s most important and most under-examined natural resource.”
The expedition was made possible through the Bloomberg-OceanX partnership and pledge of a combined $185 million over the next four years to facilitate ocean exploration and conservation around the world. Through the partnership, Bloomberg Philanthropies and OceanX aim to create a critical platform to increase the world’s collective understanding of and engagement in our oceans.

British duo compete to find world’s rarest sharks in Netflix reality series ‘All the Sharks’

British shark specialists Dan Abbott and Sarah Roberts take to the seas in All the Sharks, a major new reality TV series on Netflix.
This six-part competition follows the pair as they go head-to-head against three teams across six stunning global locations, in pursuit of the world’s most elusive sharks. With points awarded for each species spotted, Dan and Sarah must seek out elusive and unusual sharks to stay ahead in the race.
Featuring rare encounters and firsthand accounts from those on the frontlines of marine conservation, All the Sharks is an action-packed, family-friendly series that combines intense competitor drama with heart-racing underwater adventures. Underwater cinematographer and UK shark guide Dan Abbott reflects: “This series has taken us to some of the remotest parts of the world, sharing the water with iconic species.

“The sharks we encountered are unique, misunderstood and many of them, completely unknown. Shining a spotlight on these incredible animals will help people appreciate them in a whole new way.” Eco journalist, author and presenter Sarah Roberts, says.
The pair are no strangers to global adventure, having collaborated closely for seven years, with Dan typically behind the camera and Sarah in front. Their projects have taken them from the icy Arctic to tiger tracking in Indonesia. Along the way, they’ve encountered alligators and venomous snakes. But this venture is regarded as their wildest yet.
Throughout filming, Dan and Sarah captured footage of as many rare sharks as possible, using their extensive experience to maintain a respectful approach to all shark encounters and ensure minimal disturbance.
The series arrives at a time of growing interest in shark conservation in UK waters, where sightings of basking and blue sharks are growing, making the British connection to these incredible animals more relevant than ever.
All the Sharks is streaming now on Netflix.

BARE: 53 Years of Innovation

53 Years Deep
53 years ago, the idea for BARE was kindled in a small shop on the coast of British Columbia. Two passionate divers—hellbent on crafting a drysuit capable of surviving their frigid local waters—came together with a vision and a dream.
53 Years of Innovation
With every stitch, they innovated. Through every failure, they pushed. Not for profit, but for performance. To provide the sport of diving with equipment that fit better, functioned better—and lasted longer.
Ever since, BARE has continued to push, with innovations like their revolutionary Graphene Omnired® thermal technology, their impenetrable No-Stitch Technology, and their relentless dedication to Fit, Craftsmanship and Innovation.
More Than 5 Decades of Passion
Just like their founders over five decades ago, heart and passion drive every suit the BARE team make today. Because, like their founders, they don’t just make the suits—they dive in them. It’s this strong culture and unrelenting dedication that has transformed BARE from that small British Columbia shop into a truly global brand. And they’re just breaking the surface.
