The widow of a leading Arctic research who died on Saturday's First Air crash says she is overwhelmed by the outpouring of emotion her family has received.

Twelve people, including Martin Bergmann, died when First Air flight 6560 crashed near Resolute Bay's airport in Nunavut.

Bergmann, from Winnipeg, was on the Boeing 737 when it slammed into a hill while trying to land at Resolute Bay airport just before 1 p.m. on Saturday, Aug. 20.

He was the director of Canada's Polar Continental Shelf Project in Resolute and the father of four children.

His wife Sheila said that Martin was the type of man who connected with everyone he met.

"He was an incredible man, an incredible husband, an incredible dad," she told CTV News Channel on Friday morning. Adding that, "His legacy in the Arctic is actually more than I can ever imagine."

His good friend, Rob Altemeyer, said Martin's death is a big loss to the scientific community.

"He was making it possible for hundreds of scientists from all over the world to do leading research, everything from looking at climate change, to the changing nature of the north and the people who live there," Altemeyer said.

"And in his usual impassioned, yet quiet way, he was working behind the scenes to make all that possible."

Sheila said Martin was the type of man who touched everyone and who cherished his family.

"He would've been absolutely awed by all the outpouring he's received and he'd be so very grateful," she said.

The Transportation Safety Board said on Thursday that the initial report shows there was a 60-metre cloud ceiling, fog with less than five kilometres of visibility and drizzling rain at the time of the crash.

The cause of the crash has not been determined, but investigators have recovered the plane's block boxes from the wreckage.

Three people survived the crash.
