The unit of the power spectrum in the document #210

Hi,

Nice package! And, I've recently been working on power spectral analysis of ocean data. While reading the document, I noticed that the units of the two power spectrum density are different: ebd0c296ee3517c26c5cc58f4f3a265 This image is copied from the Realistic example using outputs from MITgcm section of the document. They're all power spectrum density, so the units should be the same, should they all be $m^3s^{-2}$?
