S1A. Deepwater Horizon Oil Spill: The Fate of Oil in Gulf of Mexico Waters and Beyond.
We seek research presentations that trace oil from the Macondo Well Head through the Gulf of Mexico and beyond. The depth of the oil spill, treatment with dispersants, and difficulties in detection, coupled with the large variation between estimates of the total spill amount, pose numerous interesting questions about the budget of oil in the Gulf of Mexico and beyond. Approximately one year later, initial data will enable a better idea of the fate of this oil in the marine realm and what issues will arise in the future due to its presence.
S1B. Deepwater Horizon Oil Spill: Tracing the Landed Oil and its Effects on the Gulf Coast.
Brad Rosenheim, Tulane University; David B. Finkelstein, University of Tennessee; Arndt Schimmelmann, Indiana University.
We invite presentations of biogeochemical experiments tracing oil pollution related to the Deepwater Horizon/Macondo well head blowout in the spring/summer of 2010. The focus of this session is to share early results and emerging trends in dispersion, environmental degradation, and preservation of oil from this disaster, as well as its effects on the geomorphology of the northern Gulf Coast.

Interpretation of identified processes in the context of geological history, coastal morphodynamics, physical driving mechanisms and socio-environmental consequences are invited.
S2C. Our Dynamic Coasts: Delta Plain Management—What Are We Learning From the Geological Record?
Zhixiong Shen, Tulane University; Juan L. Gonzalez, University of Texas–Pan American.
Advancing the scientific understanding regarding the geological history of the Mississippi Delta is extremely important to improving delta management and restoration planning. This session is intended to address questions related to subsidence rates, rates of various processes contributing to subsidence, delta development process, sediment budget, composition, and distribution primarily in the Mississippi Delta. Contributions about other deltas are equally welcome.

Theme Sessions

T1. Lithospheric Evolution of Southern Laurentia and the Gulf of Mexico.
Elizabeth Anthony, The University of Texas at El Paso; Jay Pulliam, Baylor University.
The lithospheric amalgamation of southern Laurentia during the Proterozoic and its evolution through consequent cycles of continent collision and rifting provides fertile ground for scientists from the Gulf region and beyond. Session themes include supercontinent assembly and dismemberment, the enigmatic Mesoproterozoic magmatic event, and the development of the current Gulf of Mexico, site of one of the largest deltaic sediment accumulations on Earth. This session will synthesize recent findings and overview papers from both geology and geophysics to provide an integration of our understanding of this fascinating area.
T2. Deltaic Sedimentation, Modern Systems, Outcrop Analogs and Extension into the Subsurface.
Janok Bhattacharya, University of Houston; M. Royhan Gani, University of New Orleans.
The focus of the session will be to bring together researchers examining deltaic systems from an experimental, modern, outcrop, or subsurface perspective.
T3. More than Meets the Eye: Geology and Geochemistry of Dark Shales of the Southern Midcontinent.
Anna Cruse, Oklahoma State University; James O. Puckette, Oklahoma State University.
We encourage talks highlighting the sedimentology, geochemistry, and stratigraphy of dark shales in the southern midcontinent, especially, but not limited to, the Barnett, Caney, and Haynesville Shales. We also seek talks on the deposition and diagenesis of modern mud-prone environments.
T4. Wetland Interfaces.
Gregg R. Davidson, University of Mississippi; Zoe J. Hughes, Boston University.
This session is open to all studies considering interactions between wetlands and bordering land, surface water, or groundwater. Interest areas include hydrology, biogeochemistry, sediment processes, and related subjects.
T5. Quaternary Faulting Along the Northern Gulf of Mexico Margin.
Nance H. Dawers, Tulane University; Nicole M. Gasparini, Tulane University.
This session will explore multidisciplinary approaches to quantifying patterns and rates of Pleistocene-Holocene normal faulting along the northern Gulf of Mexico margin. It will highlight the role of Quaternary faulting as a potential contributor to coastal subsidence and landloss and as a poorly understood control on coastal landscapes.
T6. Paleozoic Paleontology in Southern Central North America.
Rebecca L. Freeman, Tulane University; Ronald L. Parsley, Tulane University.
The excellent exposure of Paleozoic rocks in such classic field areas as the Llano Uplift of central Texas, the Arbuckle and Wichita Mountains of Oklahoma, and the Ouachita Mountains of Arkansas has long been a focus of study, but despite the volume of work produced, study is ongoing and new investigations continue to refine the interpretation of these classic sequences. This session will focus on all aspects of the fossil record of these rocks, as well as equivalent strata elsewhere, including paleoenvironmental interpretation and biostratigraphy.
T7. Transport and Sediment Dynamics in Lowland Rivers.
Ioannis Georgiou, University of New Orleans; Mead Allison, The University of Texas at Austin.
This session features integrated dynamics of flow and sediment in river systems, with an emphasis on river reaches near their outlets and linkages with the depositional receiving basin. We are soliciting contributions that employ cutting-edge technologies in the observation, analysis, and forecasting of such settings, with an additional emphasis on applications to contemporary environmental problems; e.g., coastal restoration techniques utilizing riverine sediments, effects of anthropogenic alteration in the drainage basin, timing of annual and decadal floods, mechanics of differential sedimentation, and subsequent river response and basin effects/feedbacks.
T8. Gulf Coastal Plain Groundwater Systems.
Jeffrey S. Hanor, Louisiana State University–Baton Rouge; Stephanie E. Welch, Southeastern Louisiana University.
High-quality groundwater is an essential resource for municipalities, industry, and agriculture throughout the Gulf Coast. We encourage presentations that characterize the basic hydrogeology of local or regional groundwater systems or address problems that affect groundwater resources, such as the migration of saline waters and salinization of potable groundwater resources; faults as barriers/conduits for groundwater flow; utilization of groundwater in shale gas plays; and contamination from landfills and other surface activities.
T9. Nanogeosciences in Mudrocks and Shale-Gas Strata.
Farzam Javadpour, Jackson School of Geosciences, The University of Texas at Austin.
Nanoscience is science at tiny scales. The high-tech industry, such as microelectronic and biomedical systems, has benefitted and continues to benefit from nanoscience. Recently, nanoscale characteristics of natural systems have ushered in a new era of nanoscience, including a new source of fossil energy; i.e., shale gas. Pores in these strata are at the nanometer scale, and the physics of fluid transport in the pores are different from those described by well-known formulations such as the Darcy equation. Characterizing pore networks in these systems and developing new formulations for fluid flow in such systems are of great importance and interest.
