Sea-Bird Scientific
Navis Profiling Float Product Guide

Print version

Profiling floats are providing unprecedented sampling of the global oceans through the international Argo program and other global programs. The Sea-Bird Scientific group of companies (Sea-Bird Electronics, WET Labs, and Satlantic) has created a family of float products for measuring biogeochemical properties, in addition to the more traditional CTD measurements. And, the new 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.
