17 Gypsum, Keechi Hills, Cement Oklahoma. Garrett left his beloved Healdton-‐Lone Grove area in southern Oklahoma to work in Houston for Quantico Energy Solutions. Ethan Hill’s defense was the final one of 2017. Ethan used core and wireline logs to construct a shelf to basin stratigraphic framework of Mississippian strata in east-‐ central Oklahoma. Ethan now works for Hoss Geosciences and is becoming an expert on the Anadarko basin. Continuing research topics include the Medrano sandstone, Springer-‐Goddard interval, Cleveland sandstone, Mississippian limestone, Cherokee Group sandstones, fault distribution and oil fields in northern Oklahoma, Osage Layton/Cottage Grove sandstone, upper Morrow sandstone and the Union Valley- ‐Cromwell interval. In addition, I am fortunate to serve on a number of M.S. thesis and Ph.D. dissertation committees of students researching diverse and interesting topics, an experience that allows me to continue learning. With that in mind, I wish to express appreciation to our alumni and friends who offer support for our research by contributing data, funding scholarships and fellowships, and mentoring students. Dr. Tracy Quan Associate Professor; Geochemistry, Stable Isotope Geochemistry; Organic Paleocean-‐ ography and Sedimentary Geochemistry Hello from sunny Southern California, where I am spending the second half of my 2017-‐2018 sabbatical at Caltech. So far, the sabbatical has been a nice break from my normal University workload, and I am looking forward to incorporating new techniques and collaborations into my future research. The highlight of my 2017 was sailing on the Joides Resolution as a geochemist on the International Ocean Discovery Program (IODP) Expedition 369, investigating Cretaceous climate and tectonics in the Southern Ocean off of Australia. The expedition lasted from late September to late November, and drilled 5 Sites, recovering approximately 2500 m of core. Intervals cored include Cretaceous ocean anoxic events (OAE), Eocene climatic events, and even a sequence from the Cretaceous-‐Paleogene boundary mass extinction, which should provide research topics and samples for a lot of interesting projects. It was a great opportunity and experience, and I’m glad I was able to go, even though the seas were rough and I spent a couple of days being horribly seasick. In addition to science research, the expedition scientists also participated in television and radio interviews, contributed to student outreach broadcasts, and wrote blog posts for the JR website. If you’re interested, you can read contributions from me and the other researchers on the online blog at joidesresolution.org/expedition /369. The pictures alone are worth the visit! In other news, Leye Adeboye’s Ph.D. research project into the geochemistry of the Mississippi Lime Reservoir looks very promising, and he is making steady progress. His proposed project earned him two research grants last year, the R. E. McAdams Memorial Grant from AAPG, and the Herb and Shirley Davis Fellowship from the Oklahoma Geological Foundation. Wentz Undergraduate Research Award recipient Kristen Sigl presented a poster on her research project at the GSA South- ‐ Central section meeting this past spring, and from all accounts it was well-‐received. Other research projects still in progress Dr. Tracy Quan preparing core for geochemical analysis on the Joides Resolution during Internaional Ocean Discover Program Expedition 369 in the Southern Ocean south of Australia in Fall 2017. Dr. Quan and colleagues examin-‐ ing core on the Joides Resolution.
