Unmanned underwater vehicles like this are part of the plan for monitoring Arctic waters. ((DRDC Atlantic)) Jimmy Thomson is a videojournalist based in Hay River, NT.

Department of Defence scientists arrived this week on Devon Island, Nunavut, to work on a new system to monitor Arctic waters.
"It’s important from a sovereignty perspective; if Canada has sovereignty over this part of the world, we need to know who’s there," says Dr. Dan Hutt of Defence Research and Development Canada [DRDC].
"This is part of that solution."
Hutt is the director of the project, called the Canadian Arctic Underwater Sentinel Experiment, or CAUSE. It consists of developing and testing a number of new technologies at a remote military station in Gascoyne Inlet.
The station is a stone’s throw away from Beechey Island, where graves from the doomed Franklin Expedition were found.
But the roots of the station itself are a throwback as well — to the Cold War, when the location acted as a choke-point to monitor any Soviet submarines passing through the Arctic. Vessels travelling the most common route down Lancaster Sound have to pass within earshot of the station.
Today, the work taking place there has echoes of its submarine-monitoring past.
"DRDC is investing quite a bit of money to look at other sort of innovative ways to do surveillance over the approaches to Canada with emphasis on the North," says Hutt. Artificial intelligence and roving sensors
CAUSE, with a price tag of approximately $16 million, has several goals: developing underwater microphones that can be left on the Arctic seabed for years at a time, with a long-lasting power supply to match; working on autonomous underwater vehicles that can patrol the Arctic while towing sensors; and even developing artificial intelligence software that can analyze the sound as it comes in, rather than devoting a human analyst to constantly monitoring the area.
"It’s still got quite a ways to go until we’ve got a computer with enough artificial intelligence to reliably analyze tons of acoustic data and say, ‘that’s a ship, that’s a whale, and, oh, that looks like a submarine,’" says Hutt.
"We can’t do that reliably enough right now. At least not reliably enough for operational use. There always has to be a human in the loop these days."
The autonomous underwater vehicles come with their own challenges, like working under ice, having long range capabilities, and being able to dock at an underwater station and transmit data without human interference.
The project could be one of the ways the military will replace the aging North Warning System radar line, built in the 1980s, that currently keep an eye on the north, watching for ships, missiles, and other threats.
It is also intended to watch the increasing number of civilian vessels that take the Northwest Passage, either for tourism or shipping. Many smaller vessels don’t have the tracking systems that larger ships have, and with fewer eyes on the water and no deepwater ports to house Coast Guard ships, search-and-rescue is exponentially more challenging in the icy labyrinth of the Canadian Arctic archipelago. Civilian scientists could be involved
The military has plans to loop in civilian organizations on the scientific work. Documents obtained by CBC point to an intention to work with Ocean Networks Canada, which runs the VENUS and NEPTUNE sensor arrays — giant underwater "laboratories" off the coast of British Columbia that monitor marine life and ship noise and perform other monitoring on the ocean floor.Richard Dewey, an associate director at […]
