13 sequence stratigraphy from core and logs), and our newest member, Elizabeth Elium, M.S. student (also doing regional sequence stratigraphy using core and logs). Field Work in the Paradox Basin of Utah One of the focal part of our group’s educational activities is field trips to world class carbonate systems. While we have not yet done one this year, the Bahamas and Paradox Basin are on our priority list. Gracious financial donations by recent graduates Buddy Price (M.S., now at Devon), Stephanie LeBlanc (M.S., now at ExxonMobil) and Miranda Childress (M.S., now at Devon) will make these trips possible and are tremendously appreciated by both me and the group. Best Wishes to all, Mike Grammer Dr. Jay Gregg Professor; V. Brown Monnett Chair of Petroleum Geology; Carbonate Petrology, Sedimentology and Sedimentary Greetings to all of the alumni and friends! We are in the last year of the Mississippian Consortium and my Ph.D. student, Sahar Mohammadi and I are trying to get things wrapped up. We have the Ozark-Cherokee Platform part of the study finished and Sahar is nearly done writing that up. We also have all of the data for the northcentral Oklahoma portion of the study and are trying to make sense out of it. Taylor Ewald has finished his study on the diagenesis of Mississippian rocks in northCentral Oklahoma and we will be incorporating that into the overall study. Britney Temple is making progress on her M.S. thesis on the Ordovician underlying the Tri-State (Oklahoma, Missouri, Kansas) area. At this writing she is collecting fluid inclusion data, which is a rather tedious task. Her thesis should provide clues to the origin of fluids that we see in the overlying Mississippian of that region. Gina Callaway is working on her M.S. study of the Middle Ordovician of the Michigan Basin and getting some very nice results with her cathodoluminescence petrography. Jordan Ray is starting his M.S. thesis on Silurian rocks of north-central Oklahoma. A new student has joined our little group; Gina Lukoczki from Budapest Hungary (by way of Edmonton, Alberta) is starting a Ph.D. program with us. She will be working on the diagenetic history of Middle Triassic carbonates in the Mecsek Mountains of southwestern Hungary (pronounced like “the Magic Mountains”). So we will be planning some field excursions to central Europe soon. Anybody want to go with us? Gina tells me that Hungarian wines are quite good. In May we all are planning to attend the PACROF XIII conference (PanAmerican Current Research on Fluid Inclusions) to be held in Columbia, Missouri. Several of the students are intend to give presentations. I have two papers that finally came out this past year, both in the journal “Sedimentology”. One on work on the Isle of Man and the second a review of dolomite mineralogy and the microbial model for dolomitization. This year I am working with my colleagues here at OSU on an AAPG memoir on the Mississippian of the Midcontinent. Last summer I attended the 15th Bathurst Meeting of Carbonate Sedimentologists in Edinburgh, Scotland. Aside from the great whiskies that I tasted I got to go on a fieldtrip to visit Hutton’s Unconformity at Siccar Point. From Scotland I traveled on to Ireland where Mickey was staying with a friend and we spent a couple of weeks driving to Connemara in the west and then back to Dublin. In September I traveled to the inaugural Mountjoy Conference on carbonate reservoirs where Mike Grammer and I chaired a session on unconventional carbonate reservoirs. The conference was held in Banff, a beautiful location, but was marred by a smoky haze from the forest fires in Washington State. As always I am looking forward to seeing many of you at the annual banquet in April. Best wishes to everyone. Dr. Todd Halihan Professor; Hydrogeophysics; Hydrogeology of Fractured and Karstic Aquifiers For Dr. Halihan, 2015 was a busy year. Lauren Guidry and Valina Sefa defended their M.S. theses and his visiting Ph.D. student from Brazil, Paulo Galvao got through his dissertation defense at the University of São Paulo, Brazil. Thirteen undergrads are part of the group as the BPSoG tries to get undergrads more experience for working or heading to a graduate program. Four M.S. and two Ph.D. students round out his group. At GSA, spring was spent organizing the sectional meeting for March 2015 which was held on the OSU Campus! With great donor support from companies around the U.S., and the faculty and students in organizing the event, OSU attracted 437 participants from around the world. Dr. Halihan’s company, Aestus, LLC, continues to evaluate contaminated sites using OSU intellectual property developed at the campus. This has been another busy year and growth seems like it will continue. The company presented at GSA and also hired another alum from the geology department, Greg Federko. On the home front, the Halihan home continues to host parties for the department. The home is starting to look like a research location with a seismograph and undergraduate projects going on. His
