Description

TOP 18 was deployed on 45cm thick ice in a variable thickness ice floe on 9 October 2025 at 76° 5.886’ N, 132° 56.280’ W as part of the Beaufort Gyre Observing System (BGOS) cruise on the CCGS Louis S. St. Laurent heavy icebreaker. The TOP began operating on a sampling schedule of 6 two-way or “yo-yo” profiles between 1 and 760 meters each day.
