ITP 48 was deployed on a 1.2 m thick ice floe in the Transpolar Drift during the ARK-XXVI/3 cruise (TransArc) on the R/V Polarstern as a contribution to the Hybrid Arctic/Antarctic Float Observation System (HAFOS). On the same icefloe, an Optimare ITAC with GPS mast, an Ice-Tethered Bio-optical Buoy (ITBOB), and a US Army Cold Regions Research and Engineering Laboratory (CRREL) Ice Mass Balance Buoy (IMB 2011-L) were also installed. The ITP included a dissolved oxygen sensor and full biosuite system, and operated on a pattern profiling sampling schedule. More information on the biosuite sensor package and data handling can be found here.
