St. Laurent. On the same icefloe, an Environment Canada Ice Mass Balance Buoy (IMB) and Marlin-Yug Uptempo buoy were 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 8 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 .
