Never-before-seen images beamed live from bottom of Gulf of St. Lawrence
A systematic speed in a Gulf of St. Lawrence is divulgence never-before seen images of peculiar and profitable sea life.
Federal researchers have assimilated with a non-profit organisation Oceana Canada to use a $6-million robotic submersible, famous as ROPOS, to try a seabed, and live tide infrequently fantastic high-definition video to a internet.
“The Gulf of St. Lawrence has never been explored with a form of record we have,” Oceana’s scholarship director, Robert Rangeley, pronounced in an talk Monday from Cheticamp, N.S., where a two-ship speed was staid to start another week of exploring a Gulf’s depths.
“There’s frequency been any camera work during all.”

Alexandra Cousteau, granddaughter of a famous French filmmaker and sea conservationist Jacques Cousteau, is partial of a speed and an confidant to Oceana, an general sea charge organisation formed in Washington, D.C.
“It’s such a disturb to be partial of something that has never been finished before,” Alexandra Cousteau pronounced in a dockside interview.

New insights
Cousteau pronounced prior studies have typically relied on a use of underwater sleds that were dragged along a sea building and after hoisted to a aspect for investigation by scientists.
“What they got during a aspect was broken,” she said. “They had no thought how a class were interacting. We’ve been means to see how that whole community works.”
In particular, Cousteau pronounced a high-tech submersible — ROPOS stands for Remotely Operated Platform for Ocean Sciences — has available video images of vast numbers of youthful redfish seeking preserve among fields of sea pens, a form of bottom-dwelling coral that looks like out-of-date pens done from illusory feathers.

Redfish, that are also famous as sea perch, are a commercially profitable class that have been on a decrease for years.
But a video suggests a class might be creation a comeback, as some Gulf fishermen have already suggested.
“If this is where a juveniles are anticipating shelter, afterwards we need to strengthen that,” pronounced Cousteau. “I consider that’s something everybody can determine on.”
Gulf ‘a flattering sharp-witted place’
Rangeley, a investigate scientist who used to work with World Wildlife Fund Canada and a Fisheries Department, pronounced he and his colleagues have also speckled porbeagle sharks, right whales, cod, sponges and vast schools of silt lance, a herring-like fish that is a pivotal source of food for whales and seabirds.
“We saw vast schools of them for a longest time,” a sea biologist said. “We could frequency see by a lens of a ROPOS … It’s a flattering sharp-witted place, a Gulf of St. Lawrence.”

At one point, a cameras prisoner a impulse when a northern gannet, a vast seabird famous for a torpedo-like fishing skills, plunged into a H2O to feast on silt lance.
“We’re also measuring stuff,” Rangeley said, adding that speed scientists are holding samples for genetic and chemical analysis. “We’re not only holding flattering pictures. It’s a full-spectrum scholarship effort.”
World’s longest coastline
The investigate is critical since Canada has a world’s longest coastline.
The sovereign supervision has committed to conserving 10 per cent of a country’s sea areas by 2020.
The speed started final week off a seashore of Quebec’s Anticosti Island, and afterwards changed to a American Bank, a submarine precipice fibbing off a eastern tip of Quebec’s Gaspé Peninsula.
More scrutiny is approaching this week off a west seashore of Cape Breton.

Oceana, determined dual years ago in Canada, was partial of a identical speed in a Gulf of Maine in June.
The ROPOS submersible, that can dive to 5,000 metres, is being carried aboard a CCGS Martha L. Black, a Canadian Coast Guard light icebreaker.
The submersible is owned by a Canadian Scientific Submersible Facility, formed in North Saanich, B.C.
