SGER: Testing a novel hypothesis for the cause of the Givetian/Frasnian portion of the Devonian Mass extinction: sampling and isotopic analysis of Devonian strata from the Canning Basin, AustraliaPeter WardUniversity of WashingtonEar-0827385AbstractThis project is to study Devonian-aged strata in the Canning basin, WesternAustralia, for evidence linking short term global warming to the known mass extinction occurring during the late part of this geological period. The work will entail a month of field collecting and museum study, followed by intensive laboratory analyses that will examine the stable isotopes of carbon, oxygen, and sulfur. This latter work will be the basis of a graduate student thesis at the University of Washington. The goals of the project are to test various hypotheses relating to extinction mechanism, and to see if any of the ancient processes can be related to modern day atmospheric or global oceanic changes.

摘要本项目旨在研究西澳大利亚坎宁盆地泥盆纪时代的地层，寻找短期全球变暖与发生在该地质时期后期的已知物种大灭绝之间的联系。这项工作将需要一个月的实地收集和博物馆研究，随后是密集的实验室分析，将检查碳、氧和硫的稳定同位素。后一项工作将成为华盛顿大学研究生论文的基础。该项目的目标是测试与灭绝机制有关的各种假设，并看看是否有任何古老的过程可以与现代大气或全球海洋变化有关。
