Lichlyter, Stephen Alvah (Texas A&M University, 2006-08-16)Bahia Grande is a large lagoon located within Laguna Atascosa National Wildlife Refuge in Cameron County, Texas. When the Brownsville Ship Channel was built along the southern end of the lagoon in 1936, Bahia Grande was ...

Flake, Ryan Christopher (2012-07-16)Previous studies have identified δ¹³C events in the Carboniferous that imply major shifts in the carbon cycle. However, inherent in this interpretation is the assumption that epicontinental seas are chemically representative ...

Slone, Elizabeth Dunbar Jones (Texas A&M University, 2004-09-30)For more than 100 years, Pennsylvanian permineralized peats have been studied for their exceptionally preserved plant remains. Late Atokan-early Desmoinesian coal balls from the Williamson # 3 deposit in south-central Iowa ...

Aydin, Tuba (2013-06-17)This study aims to document the dinoflagellate cyst biostratigraphy and paleoenvironmental record of the Maastrichtian Neylandville and Corsicana Formations and the lower part of the Danian Kincaid Formation from the Brazos ...

Sturdy, Michael Dale (Texas A&M University, 2006-10-30)The facies architecture and geometry of stratigraphic surfaces within a lignite bearing interval of the Paleocene upper Calvert Bluff Formation is mapped on a photomosaic of the 150 ft (50 m) high and 12,000 ft (4km) long ...

High-Resolution Characterization of Reservoir Heterogeneity and Connectivity in Clastic Environments Hull, Thomas Frederick (2011-10-21)This study developed new concepts and interpretative methods for mapping reservoir heterogeneity and connectivity of a fault controlled Wilcox clastic reservoir in Texas, USA. The application of high-resolution seismic ...

Tao, Kai (2012-10-19)This Ph.D. dissertation integrates stable isotope and trace element geochemistry in modern and fossil gastropod shells to study low-latitude marine paleoenvironments. First, stable isotopes (delta18O and delta13C) and Sr/Ca ...
-
Gentry, David Keith (Texas A&M University, 2006-08-16)We test the fidelity of shallow-water gastropod skeletons as multi-proxy archives of seasonal paleo-environmental change by performing isotopic and trace-metal analyses on specimens of Conus ermineus from the Gulf of Mexico. ...

Hendricks, Jennifer Kathleen (2019-11-08)Methane-derived carbonates occur in siliciclastic settings globally and precipitate from bicarbonate derived from methane oxidation. Methane-derived carbonates, which occur from the Archean to the present, take diverse ...

Strauss, Josiah (2012-02-14)Hypoxia, with dissolved oxygen levels < 1.4 ml L-1, is a recurring summer feature of Louisiana shelf bottom waters. Stable isotope characterization (delta^18O and delta D) of surface waters over the hypoxic zone shows a ...
