TOP5 was deployed on an 1.7 m thick ice floe in the Beaufort Sea on September 25, 2022 at 79 10.2 N, 140 16.9 W as part of the Beaufort Gyre Observing System (BGOS) during the JOIS 2022 cruise on the CCGS Louis S. St. Laurent. On the same icefloe, an Ice-Tethered Profiler (ITP136), a US Army Cold Regions Research and Engineering Laboratory (CRREL) Seasonal Ice Mass Balance Buoy 3 ,and a Naval Postgraduate School Arctic Ocean Flux Buoy (AOFB47) 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.
