Thanks! That's an important piece of info.
I managed to locate a page that has the Schiermeier Nature article in full.
The original Geophysical Research Letters paper is here. (pay per view)
The correction mentioned in the article is here. (also pay per view, but pretty much just covers what Scheirmeier said)
Further links to keep an eye on:
The ARGO home page
Willis' latest work, which is apparently being presented this week(!) Stay tuned.
