Biotic Response of Ostracodes to the Middle Eocene Climatic Optimum (MECO; 40.0 Ma) in the Southern Indian Ocean (ODP Site 748): Jared Warner, M.S. Candidate, Department of Geological Sciences, San Diego State University - The long-term cooling trend from “greenhouse” to “icehouse” conditions through the middle-to-late Eocene (49.0 – 33.7 Ma) was interrupted by the middle-Eocene Climatic Optimum (MECO; ~40.0 Ma), a transient (~500 kyr) global warming of ~4-6 C° widely recorded in...

Mytilus californianus as an environmental monitor: a case study from central California: Frank Forcino, M.S. Candidate, Department of Geological Sciences, San Diego State University - Intraskeletal oxygen stable-isotope ratios (δ18O) and minor element ratios (Mg/Ca) were examined in modern Mytilus californianus specimens to test the hypothesis that these variables record ambient seawater temperature, and therefore can be measured in fossil specimens as a means of reconstructing...

Magnetotelluric Investigation of the Santo Domingo Basin, Rio Grande Rift, New Mexico: Peter Winther, M.S. Candidate, Department of Geological Sciences, San Diego State University - Magnetotelluric (MT) investigations of the Santo Domingo Basin were made in 2000-2007 to assess the deep stratigraphy and tectonics of an intra rift basin. The studies were conducted during the SAGE (Summer of Applied Geophysical Experience) program to provide ‘hands-on’ learning experiences for students and...

Latitunal Controls on the Martian Crater Densities: Dylan Collins, B.S. Candidate, Department of Geological Sciences, San Diego State University: In order to gain new insight into Mars’ planetary dynamics, an examination of Martian crater densities as a function of latitude was completed. There are two complete crater catalogs of the Martian surface; one manually compiled by Nadine Barlow and one compiled by crater counting software created by Tomasz Stepinski and colleagues. After loading...

Using XRD Peak Broadening Analysis on Quartz to Identify Shatter Cones of the Santa Fe New Mexico Impact Structure: Robert Edie, B.S. Candidate, Department of Geological Sciences, San Diego State University - In addition to such large-scale features as craters and remote sensing anomalies, evidence for meteorite impact events is abundant at both micro- and mesoscopic scales. Micro-structural damage, planar deformation features, and planar fractures within quartz and other silicate mineral...

Seismic Anisotropy in the Julian Schist, San Diego CA: Robert Gallardo, B.S. Candidate, Department of Geological Sciences, San Diego State University - P-wave velocity measurements of a Julian Schist rock sample collected in the Laguna Mountains region of East San Diego County show significant P-wave velocity anisotropy at near surface conditions. Multiple P-wave velocity measurements were taken from orthorhombic cut sample of Julian Schist using the Tico Ultrasonic Instrument with varying...
