Fig. 3
Example of dissolved oxygen profiles after the inverse filtering correction. (a) Original O2 profiles for ascending (‘up’ red lines) and descending (‘down’ blue lines) dives. (b) An inverse filtering correction (see Bittig et al.16) is applied to the same dives, but noise is amplified. (c) A modified inverse filtering method is applied to reduce noise amplification. Original profiles are down for reference (‘up’ black dotted, ‘down’ black dashed).
