• Description:
  Serendipitous measurements of deep internal wave signatures are evident in oscillatory variations around the background descent rates reported by one model of Deep Argo float. For the 10,045 profiles analyzed here, the average root-mean-square of vertical velocity variances, √ ⟨′2⟩ , from 1,000 m to the seafloor, is 0.0045 m s −1, with a 5%–95% range of 0.0028–0.0067 m s −1. Dominant vertical wavelengths, λz, estimated from the integrals of lagged autocorrelation sequences have an average value of 757 m, with a
