Calling all AGU members

Andy Revkin at dot Earth recently posted the amended AGU statement on climate change on his blog. A obstructionist politician challenges the statement, saying that it was made by the union leadership without any support or knowledge by the membership. In response, Mr. Revkin asked any and all AGU members to stop by his blog and state their opinion on the matter. So here is the link. You get your comment put in bold, and if you are lucky, you might even get some linkage love from the New York Times.

Personally, I’ve never seen a blog with 10,000 comments before, so even if we can only get 20% of the membership to chip in, that would be something…

Hi Chuck-

Thanks for the head's up - did my civic duty.

Say, did you ever see a high m/e = 48 background that was decoupled to the 29 background. I'm starting to do Ti in quartz and had a surprise last week.

Looks like you're having fun being a dad.

Running a lot of carbonates? Check your 44, or your 46/48 ratio.

96Zr++ is an unlikely candidate, but if that is the problem, then there should be a gigantic 90+ background (and significant 91, 92, 94, and 96), and those masses are usually very clean.

Which instrument do you have again?

Another unlikely candidate is ozone, but that should correlate with N if it comes from air. You don't do anything silly like bleed O2, do you?

If none of those helps, just make note of the bkg before and after each day when you're running Ca-poor phases like mantle stuff or sulphides or zircons. If it jumps/drops unexpectedly, check the bulk comp of whatever you just ran. Might take a few months, but writing everything down is surprisingly useful, if laborious, for troubleshooting.

Fine suggestion!
