The Influence Of The Tibetan Plateau Elevation On The Global And Asian Monsoons, Rene Paul Acosta Jan 2013

The Influence Of The Tibetan Plateau Elevation On The Global And Asian Monsoons, Rene Paul Acosta

Open Access Theses

It has been long hypothesized that large-scale topographic changes, such as the surface uplift of the Tibetan Plateau, impacts the development of the South Asian and East Asian monsoons and influences other monsoon regions. However, recent modeling has shown that spatial distribution of the global monsoon, which includes the South Asian and East Asian monsoons is largely unaffected by the elevation of the plateau. In this study, we present results from a series of modern day simulations using CESM1.0 in a mixed-layer (slab ocean) configuration. The Tibetan Plateau height is varied from double that of the modern maximum plateau elevation …


Analysis Of The Cyclostratigraphy At The Devonian-Carboniferous Boundary In South-Central Oklahoma, Ryan Michael Todd Ellis Jan 2013

Analysis Of The Cyclostratigraphy At The Devonian-Carboniferous Boundary In South-Central Oklahoma, Ryan Michael Todd Ellis

LSU Master's Theses

An outcrop in La Serre, France, was officially ratified by the ICS in 1989, and the IUGS in 1990, as the location of the Global Boundary Stratotype Section and Point (GSSP) for the Famennian–Tournaisian, and subsequently the Devonian–Carboniferous (D–C) boundary. GSSPs, like this one, are official outcrops that provide physical representations of geologic time boundaries, essentially geological standards that define geologic time, providing a vital framework to model a variety of interpretations of geological phenomena from paleoclimate to paleontological. It has been acknowledged that the GSSP in La Serre, France is in need of revision due to fossil reworking and …
