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. It’s only been a few months and already the gephs are proving their worth. 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. Could it be that ocean pH actually responds more to the PDO than it does to the mechanisms asserted by the Feel2899.pdf team and their colleagues? Given that the PDO, somewhat like Henry’s Law, relates to both temperature and pressure, maybe this is a quite natural outcome.
I was planning to hold out for submittal to peer review, but as usual this might be important to post right away, if only to buy the gephs some more time. I’ll keep working this up as I go forward. And of course, this is only a blog for now. If any reader can show I’m wrong, I’m happy to correct.
Authors note: Ha, I’ve found much new information of interest. Stay tuned for more developments!
