I am very happy to report that Yohei Takano’s Argo O2 paper got just accepted. This is the first paper to link the strong and recurring vertical fluctuations of thermocline tracers to the inertial frequency, as far as I know. With the profiling frequency of about a week, this signal is of course aliased.
