TOP2 was deployed on an 0.85 m thick ice floe in the Beaufort Sea on September 2, 2021 at 78 34.9 N, 147 15.5 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2021 cruise on the CCGS Louis S. St. Laurent. On the same icefloe, an Ice-Tethered Profiler (ITP127), 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.
