In situ phase-domain calibration of oxygen Optodes on profiling floats

Comparison of profiles from oxygen Optodes deployed on profiling floats with ship-based bottle casts taken at the time of deployment shows typical low biases of approximately 0 to −40 μmol kg−1. Most proposed methods to correct these biases use linear or multiplicative corrections of the derived variable O2. Some of these methods depend on specific reference data such as deployment casts or air measurements. Here, we describe a versatile in situ...
