Description
TOP9 was deployed on a 0.5 m thick ice floe in the Beaufort Sea on September 25, 2023 at 79° 24.1 N, 149° 58.6 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2023 cruise on the CCGS Louis S. St. Laurent. On the same icefloe, an Ice-Tethered Profiler (ITP139) and a US Army Cold Regions Research and Engineering Laboratory (CRREL) Seasonal Ice Mass Balance Buoy 3 were also installed. The TOP is operating on a standard sampling schedule of 6 two-way profiles from the surface to 200 m depth each day.
