ITP87 was deployed on a 1.20 m thick icefloe in the north Beaufort Gyre on August 28, 2014 at 79 58.6 N, 152 38.2 W from the R/V Xuelong (Snow Dragon) as part of the CHINARE 2014 Expedition. The ITP is operating on a standard sampling schedule of 2 one-way profiles between 7 and 760 m depth each day.
