Global Ocean pH and the Pacific Decadal Oscillation
The ocean thermal oscillations captured by the Pacific Decadal Oscillation (PDO) [1, 2] have a new parameter to share their gyrations with. Or at least it seems that way from my initial perspective. Here is a preliminary chart comparing the time series of global ocean mean pelagic pH that I developed in [3] and the PDO index (as archived at http://jisao.washington.edu/pdo/PDO.latest).
It looks like a candidate trend of potential value. Given that the PDO, somewhat like Henry’s Law, relates to both temperature and pressure, maybe this is a quite natural outcome.
