Dissolved oxygen (calibrated) collected from Argo profiling floats in world-wide distribution from 2002-09-08 to 2015-08-30 (NCEI Accession 0172813)

This dataset contains recalibrations of previously deployed Argo oxygen floats using a procedure described in Drucker, R. and S. C. Riser (2016), In situ phase-domain calibration of oxygen optodes on profiling floats, Methods in Oceanography, 17, 206-318, https://doi.org/10.1016/j.mio.2016.09.007.

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.

in situ calibrations were performed on 147 Optodes floats deployed on UW floats between 2004 and 2015 using only World Ocean Database (WOD) references. Median differences to World Ocean Atlas (WOA) 2009 climatology were reduced from ∼6% to ∼1%. Deployment casts were used to estimate error for eight Argo floats deployed in the Indian and Pacific Oceans; the aggregate error was reduced from 8% to 0.3%.
