Prof. Liner is Department of Geosciences Chair at the University of Arkansas, holds the Maurice F. Storm Chair of Petroleum Geology and served as 2014/5 SEG President.
Liner earned a BS in Geology (U. Arkansas, 1978), MS. in Geophysics (U. Tulsa, 1980), and PhD in Geophysics (Colo. School of Mines, Center for Wave Phenomena, 1989). He has 11 years industrial experience in exploration (Conoco) and geophysical research (Western Geo, Fairfield, Saudi Aramco). From 1990-2004 Liner was a faculty member in Geosciences at The University of Tulsa. In January 2008 he joined the faculty of the University of Houston as Professor and Associate Director of the Allied Geophysical Labs industrial consortium. In fall 2011 he was named Department Associate Chair and Interim Chair in spring 2012.
Prof. Liner’s research interests include Petroleum reservoir characterization and monitoring, CO2 sequestration geophysics, advanced seismic interpretation methods, seismic data analysis and processing, near surface, anisotropy, and seismic wave propagation. He has served as Editor of Geophysics (1999-2001), authored many technical papers, scientific meeting abstracts, The Leading Edge column Seismos (since 1992), and the text book Elements of 3D Seismology soon in 3rd edition. Liner is a member of SEG, AAPG, AGU, EAGE and the European Academy of Sciences.
Just wrapped up my 3D Seismic Exploration class on Monday. First time at University of Arkansas such a class has been offered. We had 19 in the class (including 4 undergrads!). Over two days, each student gives a presentation of his/her prospect in the Vermillion area of the Gulf of Mexico (data courtesy FairfieldNodal). The class votes for daily winners, then an overall best prospect winner.
This year's best prospect went to graduate student Greg Buratowski with runner-up being undergraduate Josh Stokes. Congratulations!
Josh Stokes (L) and Greg Buratowski (R).
A copy of the book Krakatoa was given as the Best Prospect Award.
Have added Illinois, Alabama and Canada. The latter thanks to Howard:
If you're not restricting yourself to south of the 49th parallel, here is an isopach map of the Western Canada Sedimentary Basin (WCSB): http://www.ags.gov.ab.ca/graphics/atlas/fg14_32.jpg It's a total Carboniferous isopach (includes "Pennsylvanian" equivalents), but there isn't a whole lot of that in the WCSB--some in the northern end and smaller strips in the southern Rockies, so you could mostly use this as a proxy for "Mississippian".--Howard
Priority list (any help is greatly appreciated):
5. Kansas (Miss only, see note in original post)
6. Arkansas (unlikely this exists, so we plan to make one)
I like the Illinois map that shows an outcrop area, then isopach contours when it goes into the subsurface. So far, the thickest Mississippian section is about 12800 ft (3900 m) near Boise, Idaho.
State of the Mighty Miss project 4/16/2013. MArkUP study area in blue.
The 1979 USGS paper containing most of the maps is available in two parts: A-LM-DD
**** original post *****
Reading a classic USGS report I found several state contour maps showing thickness of the entire Mississippian section (Miss isopachs). Since MArkUP is all about the Miss, I stitched the maps together in Google Earth for the big picture of Miss thickness.
The maps were rather ancient, but carefully compiled by excellent geologists. Things did not quite match up at state boundaries and some were in feet with others metric, no matter. Funny thing though, the states where I expected to get easy data are blank.
Miss isopach contour maps for some states, others needed. MArkUP study area in blue.
One would think it easy to find a Missouri map, where Miss outcrops aboud. But the internet is silent for this. Ditto for the other blank states, including my state of Arkansas.
If you can find a decent Miss isopach contour map in any graphics format, send me the file or a link. I'll note contributors on updates of this blog post.
Thanks in advance.
ps. The Kansas isopach map is from top Arbuckle to top Miss. In some parts of the state, this is all Mississippian rocks. But not in other places. So a true Miss isopach for Kansas would also be welcome.

Chap 4 Eq 9 is an invertible set of relationships between stiffness and Thomsen parameters, but the quadratic terms in the definition of delta require a choice of sign.
