Sessions at Ventura PSAAPG meeting in honor of Bill Normark
I will be in Ventura, California for a couple of days this week to attend and chair a session at the Pacific Section AAPG/SEPM meeting. A few colleagues and I are chairing two oral sessions in honor of USGS marine geologist Bill Normark.
Bill passed away in January of 2008 after a long battle with cancer. He was on my PhD committee and was a huge influence on me. I’ve been wanting to put together a post about Bill’s career for the past year but every time I sit down and attempt to write something I realize that I would need to write a book! Perhaps I will someday.
Bill was a true pioneer in the exploration, discovery, and characterization of submarine fan systems. He always utilized the technology of the day to its fullest extent — from the low-resolution bathymetry of the 1960s to the current centimeter-scale multibeam bathymetry of today. Bill’s impact was significant because he not only described and interpreted processes of modern sedimentary systems of the deep sea but wrote numerous papers increasing our understanding of the patterns we see in the geologic record.
Here is the lineup for the talks in case you’re interested.

All the presenters were influenced by Bill’s work and most knew him very well — I’m looking forward to hearing all the anecdotes (especially in the second-to-last talk by Dave Scholl).
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So, what did Dave Scholl talk about?
pretty much what the title of his talk is — he shared some anecdotes about how he and Bill (who made wine together for decades) would ponder the fate turbidite systems from ancient, now-closed oceans — Scholl concludes that most of the material was subducted (with lesser proportion being scraped off and incorporated into suture zones) … if you ever seen Dave give a talk, it’s always entertaining
