Short summary
This study assesses the spread of mean state and annual cycle of ocean dissolved oxygen by multiple observational gridded data products. A good consistency is validated globally, although substantial local differences exist in areas of strong spatial gradient. Quantifying the discrepancies could give an insight into regions relatively more sensitive to data reconstruction processes and further advance the improvement of oxygen data products.
