Profiling floats are providing unprecedented sampling of the global oceans through the international Argo program and other global programs. Sea-Bird Scientific (Sea-Bird Electronics, WET Labs, and Satlantic) has created a family of float products for measuring biogeochemical properties, in addition to CTD measurements. Navis BGCi offers an integrated data stream for all sensors on the float.

Custom solutions are also available for other applications, in consultation with Sea-Bird Scientific's R&D team.
