Lab and field experiments were conducted with 13 CONTROS HydroFlash O2 optodes to evaluate the performance of this oxygen sensor. All optodes received pre- and post-deployment calibrations (multi-point and/or two-point), and field data complemented the extensive characterization, facilitating to address information about its salinity and hydrostatic pressure dependence, its stability assessment during storage and deployment, and its time dependence as well as performance on observation platforms.

This dataset covers three different files for this Argo float profile:(1) The original data file, named as "lovapm003a_2ee4_003_01.csv"(2) The original technical file, named as "2ee4_003_01_technical.txt"(3) The processed data file that includes a reduced amount of original data as well as calculated oxygen parameters relevant for this study, named as "hydroflasho2-argo-float-test.csv"
