While it doesn’t deal specifically with the Chandler Wobble, the recent article Clues to Earth’s Wobble Come From Within from space.com details some interesting ideas about contributions to earth’s wobbles.

Cool, but how in the world would they test a theory like that?
Do they prove it with math? You sure can’t send a search party down there to look. [flash on James Mason and that big Icelandic lug and what’s-er-name, Dorothy Malone in a dress, God save us, prowling around the Earth’s core.]
You raise a valid point, but one that applies to almost all of geology and astronomy. When astronomers call things ‘neutron stars’, they haven’t actually sent Erwin the Quantum Mechanic out to check if they are actually made of neutrons.
Fade to black, cue sound of hollow-earthers chanting “Just a theory!”
That space.com article was posted to the Bad Astronomer’s site a bit ago, and I noticed that the article has a glaring error. It says “The Earth’s precession alters the time of the annual vernal and autumnal equinoxes, making them arrive earlier each year.” Of course, they don’t arrive earlier each year, because our calendar is built so they don’t. That’s one of the reasons for the Gregorian calendar, in fact. We use a tropical year, not a sidereal year.
However, if you want to go that route, here is some folk who don’t believe in precession at all: The Sirius Research Group
Is Erwin the Quantum Mechanic a real or copyrighted person? Or is he someone you made up just now? 'Cause I may need to add him to my sig, and I don’t want to step on anybody’s toes…
And I didn’t mean, “Oh, they could never prove something like that”, I meant, “How do they prove something like that? How do they test their theory? Is it math or what?” I have great respect for math, mainly because I’m so terrible at it.
Erwin the Quantum Mechanic is an appellation I made up on the spot to represent someone who is capable of measuring nuclear or elementary particles “magically.” It was inspired by Erwin Schroedinger. Quoth Cecil:
I was going to go with Joe the Quantum Mechanic but I realized that Erwin the Quantum Mechanic has a certain je ne sais quoi, but I don’t know what it is.
Feel free to use it in any context you wish, with or without credit. I’m just that kind of guy.
Thank you. 
Actually, ever since Monica dumped Tom Selleck and accepted his proposal, Chandler’s been remarkably stable.

I’m not so sure I’ve completely blown it, yet.
One of his co-authors is Richard Gross, the guy who announced four years ago that he’d solved the wobble mystery (see this old thread). They’re just trying to nail this sucker down. Again, I haven’t read the latest paper, but the measurements don’t prove much–the bulges that they are measuring could be the result of the wobble, rather than causing the wobble.
And the link to Cecil’s column in that old thread is no longer active, the column is now here.

You’re looking forward to saying Blewitt blew it.
ya got it
