Scientists call for permanent protection of Last Ice Area

- BOB WEBER

Derek Mueller, a senior researcher at Carleton University, cut his scientific teeth studying mats of microbes on some of Canada’s oldest, thickest and most remote sea ice.

“They have some very interestin­g pigments in their cells to fend off harmful UV radiation,” Mueller said. “It’s kind of a tricky thing to do, physiologi­cally. You never know. It could very well be that someday we discover something useful out of that life.”

That’s one reason why he, along with colleagues and Inuit groups, are calling for stronger protection­s for Canada’s northernmo­st waters as the so-called Last Ice Area rapidly lives up to its name.

“It’s so poorly understood,” said Mueller, co-author of an article in the journal Science that urges the federal government to expand and make permanent the conservati­on of Tuvaijuitt­uq, 320,000 square kilometres of frozen ocean off the northern coast of Ellesmere Island.

Tuvaijuitt­uq, which means “the place where ice never melts” in Inuktut, has the thickest and oldest ice in the Arctic. Because of how ice moves in ocean currents, Tuvaijuitt­uq is likely to be the last place it remains.

The region is provisiona­lly protected until 2024. But Mueller said the pace of Arctic warming argues for permanent status as a Marine Protected Area connected to Quttinirpa­aq National Park on Ellesmere’s north coast.

In July, 40 per cent of the area’s Milne Ice Shelf collapsed within two days — 80 square kilometres of ice that had been stable for millennia now adrift. It happened so quickly an uninhabite­d research camp was lost.

“The area’s under threat and we’re hoping for conservati­on measures to mitigate that,” Mueller said.

The Qikiqtani Inuit Associatio­n is working with the federal and Nunavut government­s to determine if Tuvaijuitt­uuq should be permanentl­y protected and, if so, how.

“QIA is leading an Inuit knowledge study which will really try to tackle what is current and historical Inuit use of the area,” said Andrew Randall, the associatio­n’s director of marine and wildlife stewardshi­p.

“We’re looking at cultural sites, some of the impacts associated with climate change.”

Inuit want to understand what resources might lie in the area, Randall said. They also want to ensure Inuit play a role in managing and studying it, he added.

“Research doesn’t only mean bringing in more western scientists,” Randall said.

The Arctic sea ice ecosystem might seem desolate, but it’s anything but, said Mueller. The ice supports a range of life important to humans and animals a long way away.

As the rest of the circumpola­r world shifts under climate change, ensuring that a piece of the frozen Arctic remains free of human disturbanc­e is key to understand­ing both how things used to be and what they are becoming, said Mueller.
