Parks Canada plans to record underwater sounds at Tallurutiup Imanga

Parks Canada wants to record underwater activity in four spots around Arctic Bay, in the hope of creating greater understanding of how human activity in the area affects the ocean.

“The ocean is a dynamic place,” said Clare Kines, who is the Inuit stewardship co-ordinator with Parks Canada and is managing the underwater noise study file. “It has its own soundscape, and noise propagates very well in the ocean.”

Kines spoke on the phone from Arctic Bay, where he’s lived for 20 years. The idea is that the four hydrophones—the devices that record sound under water—would be placed in locations in the Tallurutiup Imanga National Marine Conservation Area.

Tallurutiup Imanga is known as Lancaster Sound in English. It borders northern Baffin Island, where Arctic Bay is located.

Marine conservation areas are managed by Parks Canada, and this one is co-managed by Inuit stewards, or Nauttiqsuqtiit of Arctic Bay. Along with preserving areas, one of the intents behind giving areas protected status is to understand them using scientific research, Kines said.

So measuring underwater noise in Tallurutiup Imanga is meant to help the people who manage it understand “how it is right now, and if it’s changing in the future, and if anything needs to be done to better that as time goes by.”

The Parks Canada proposal is currently being assessed by the Nunavut Impact Review Board.

Parks Canada is working with the Nauttiqsuqtiit of Arctic Bay to help choose locations for the recording devices, and to perhaps help them put them underwater after the ice melts, and to take them out before it forms.

The hydrophones record for 15 minutes out of every hour and will pick up natural ocean sounds.

The four locations are Strathcona Sound, Adams’ Sound, the lower reaches of Admiralty Inlet and Admiralty Inlet in the area of Kakiak.

“The ocean isn’t silent,” Kines said. “There’s a number of different noises, everything from crustaceans to marine mammals to, in some cases, fish even create noise.”

This translates to squeaks, squeals and grunts, Kines said.

Human activity will also be recorded. That includes small pleasure craft that hunters use, to sealift ships, cruise ships, yachts, Canadian Coast Guard ships and the Canadian Navy.

“There’s a range of vessels that ply these waters,” Kines said.

Over the years, Kines has seen ship traffic around Arctic Bay decrease and then pick back up again.

It’s important to have a baseline of information about ocean activity based on noise, Kines said, so that people who manage the area know how to recognize changes.

“In many ways the ocean is a big mystery, especially the Arctic Ocean, and this is one small step in increasing our understanding of the ocean and the systems that drive it, and how it may change over time,” he said.

Parks Canada had hoped to start recording this summer, but it’s still waiting for approval. Along with the Nauttiqsuqtiit, Kines said they are consulting with the hamlet of Arctic Bay, the hunting and trappers organization, as well as community members in general.

Nunatsiaq News reached out to the QIA, the hamlet and the HTO to ask what they think of the value of the study. None of them were available for comment by deadline.

Parks Canada was hoping to start gathering data this year because the oceans are particularly quiet due to COVID-19 restrictions, Kines said. But at this point it looks like the study won’t start until next year.

There are other organizations that have done similar studies in Arctic waters. Kines hopes that data from this study will eventually contribute to a body of scientific knowledge about the Arctic Ocean.
