The Louis St. Laurent is an ice breaker vessel from the Canadian Coast Guard. The St. Laurent is working in collaboration with the USCG Ice Breaker Healy. The two vessels met and are now tied up together so scientists aboard each vessel can exchange scientific information.
As the Healy approached the St. Laurent, the scientists from the Healy were serenaded by Santa playing the bag pipes on the deck of the St. Laurent. Well, they are near the North Pole!
