The track left in the ice by Umiak 1 has now safely frozen over.
Ron Webb is a partner with Sikumiut Environmental Management Limited.
He says the track left by Vale’s shipping vessel has now frozen over to a safe thickness of six inches.
He says the pontoons used for safely crossing the track will remain in place until the next time the Umiak 1 travels into the site.
The next scheduled trip of the icebreaker is February 18.
