St. Laurent. On the same icefloe, a US Army Cold Regions Research and Engineering Laboratory (CRREL) Seasonal Ice Mass Balance Buoy (S-IMB) was also installed. The ITP includes a dissolved oxygen sensor and full biosuite system operating on a pattern profiling sampling schedule including one full one-way profile between 9 and 760 m depth every 1.5 days and a fixed SAMI PCO2 and SAMI pH at 6 m depth. More information on the biosuite sensor package and data handling can be found here .
