Oral Presentations: PowerPoint is the method of presentation. Presenters should bring their PowerPoint files (which should include either the author’s name or abstract number) on CD-ROM or USB memory device to be uploaded in the speaker ready room at least one hour before the start of the morning or afternoon session in which you will present. The speaker ready room is in the Warnock Science Building, WSB room 310, and is open 7 a.m.–5 p.m. on Thursday, 8 March and Friday, 9 March 2012.
Poster Presentations: We will supply with six Velcro sticky dots for you to use to hang your poster. Each poster presenter will be provided with a 92" wide x 65" tall posting area. Access to electrical outlets and furniture for poster sessions must be requested well in advance to the Jim Whitford-Stark, Technical Program Chair. Authors of posters for the morning session are asked to have their posters in place by 8 a.m., and should remove their posters by noon. Authors of posters for the afternoon session are requested to have their posters in place by 1:30 p.m., and should remove their posters by 5:30 p.m. Authors are expected to be available at their posters 9:30–11:30 a.m. for each morning session, and 2:30–4:30 p.m. for each afternoon session.
- Big Bend National Park and Vicinity: A Decade of Research.
Don Corrick, Big Bend National Park; Dee Ann Cooper, The University of Texas at Austin; Roger Cooper, Lamar University.
- Big Bend National Park is well known for its spectacular geologic diversity, with rocks spanning in age from the Ordovician to the Quaternary and structures representing three major orogenies (Ouachita-Marathon, Laramide, and Basin and Range). This multidisciplinary session is intended to bring together researchers who have been working in and around Big Bend National Park and to highlight new geologic information and mapping completed since the last meeting in Alpine in 2002. Both oral and poster sessions are planned.
- 1. Tectonic History of the Trans-Pecos Region.
John White, Eastern Kentucky University.
- A billion years of tectonic history are exposed in the Trans-Pecos region of far west Texas and southern New Mexico, from Precambrian Grenville rocks and structures to the Cenozoic Rio Grande Rift. This session will focus on work in petrology, structural geology, and geophysics that has contributed to the understanding of this tectonically complex and controversial region over the past decade.
- 2. The Rio Grande and Its Tributaries in the Big Bend Region: Hydrology, Water Quality, and Restoration Efforts.
Jeff Bennett, Big Bend National Park; Joe Sirotnak, Big Bend National Park
- This session will focus on recent important work in the Big Bend region regarding hydrology and the environment. Presentations should focus on geomorphology, water quality/quantity, and habitat restoration.
- 3. Mesozoic of the Western USA.
Thomas Shiller, Texas Tech Univ.
- 4. Stratigraphy and Paleontology of the Permian Basin.
Emily Stoudt, University of Texas Permian Basin; Robert Trentham, The University of Texas of the Permian Basin.
- The richly fossilifeous Permian strata in West Texas continue to be extensively studied and contain the world standard for the Middle Permian. The Permian Basin is also one of the most prolific petroleum provinces in North America and accounts for over 20% of current US oil and gas production. This session will focus on current research and issues related to paleontology and petroleum geology in the Permian Basin of west Texas.
- 5. Aquifers of West Texas.
James Ward, Angelo State University.
- Nearly 60% of water in Texas is supplied by groundwater. In arid west Texas, recharge rates for the complex aquifers lag behind the amount extracted for domestic, agricultural, and manufacturing use. The guiding principle in Texas for groundwater management is the rule of capture. Bordering states (New Mexico, Colorado, and Oklahoma) and nations (Mexico) demonstrate differing legal and cultural practices. Against this backdrop, assuring an adequate supply of water for irrigation, for industrial and municipal needs, and for the environmental needs of individual rivers, bays, and estuaries is largely a regional question. In spite of the adage — “Whiskey’s for drinking; water’s for fighting!” — solutions are emerging for addressing the universal need for water, from conservation and conjunctive use to desalination. This session will explore what is known about west Texas aquifers and the challenges and opportunities ahead.
- 6. Geoarchaeological Investigations in the Big Bend Region, Southwestern Texas.
Andy Cloud, Center for Big Bend Studies, Sul Ross State University.
- Recent archaeological and geoarchaeological investigations sponsored by the Center for Big Bend Studies of Sul Ross State University have greatly facilitated the understanding of human occupational zones within late Pleistocene and early to middle Holocene deposits in the Big Bend region of Southwestern Texas. This session will concentrate on findings dated through radiocarbon assays from the Early Paleoindian, Late Paleoindian, Early Archaic, and Middle Archaic periods, roughly spanning 7,000 years (ca. 11,000–4,000 B.P.).
- 7. Issues in Earth Science Education.
Kevin Urbanczyk, Sul Ross State University
- “What is it with kids these days?” The youth of today are both unnervingly familiar with technology and reflecting a vastly different world view and values system than we remember ourselves at their age. The changing demographics of our nation and emerging debates within geology, education, and politics make for a very interesting atmosphere for educators. This session explores successful strategies for attracting and educating the next generation about Earth.
