Last November I probably posted that I did a quick interpretation to judge how old some sediments were before we cored them, and I was off by a factor of 2, because some quick and dirty processing (that I did not do) did not show a fault. There is a joke that I thought I was wrong once but I was wrong. It is not completely resolved yet, but it looks like I was a lot closer than we thought at the time.

This is interpretation of seismic reflection data offshore Santa Barbara-UCSB for possible deep coring by the International Ocean Drilling Program, for paleo-climate over the last 1 million years or a bit more. We (C. Nicholson lead with Jim Kennett and Rick Behl and others) had a very successful cruise in 2005 (posted here) to get short cores and the Kennett lab and others have dated these; I and I student C. M. are correlating various dated horizons. Santa Barbara Basin is a world-class paleo-climate site and showed in the early 1990s along with a Greenland Ice core that you can have sudden climate changes (meaning, big changes within a decade). This idea is the real bogeyman for the politically-driven climate change deniers.
