0001183MalinThis project involves a near-surface 3D geophysical investigation of the drill site area near Parkfield, CA for the San Andreas Fault Observatory at Depth (SAFOD). Major portions of the fieldwork and data analysis will include advanced training of students in the investigation methods and extensive interactions between industry, government, and the universities involved in the investigation. The scientific purpose of the investigation will be to further characterize the near-surface fault and basin structure of the site. Knowledge of the near-surface structure is essential for interpreting the results of the deeper drilling and more regional geophysical investigations that are currently planned. In addition, these data will help to establish some of the near surface complications the drilling effort may encounter. The geophysical methods to be included in the site investigation are potential field and field gradient profiling, seismic profiling, magnetic field survey, and radar profiling.The drill site investigation will be conducted as part of an advanced, multi-university near-surface geophysics field camp and seminar. The camp will also be used as a focus for industry-university-government cooperation and interaction on the SAFOD project. The camp will primarily include students from Duke, Stanford and UC Berkeley, but will also be open to students from Questa College Cal Poly San Luis Obispo, and other institutions participating in the SAFOD effort. The educational purpose of the field camp will be two fold: 1) to demonstrate the techniques and value of 3D geophysical surveying and data; and 2) to acquaint a large group of students with the scientific objectives and research possibilities of the SAFOD program. By sharing the data in an open and coordinated fashion between each of the participating institutions, it is hoped that several competing models of the drill site will emerge, with the ultimate test being provided by the drilling itself.***

这个项目涉及对加利福尼亚州帕克菲尔德附近的圣安德烈亚斯深部断层观测站(SAFOD)钻探现场区域进行近地表3D地球物理调查。实地调查和数据分析的主要部分将包括对学生进行调查方法的高级培训，以及行业、政府和参与调查的大学之间的广泛互动。调查的科学目的将是进一步确定该地点的近地表断层和盆地结构。对近地表结构的了解对于解释目前计划进行的更深层次钻探和更多区域地球物理调查的结果至关重要。此外，这些数据将有助于确定钻探工作可能遇到的一些近地表复杂情况。现场调查的地球物理方法包括势场和场梯度剖面法、地震剖面法、磁场剖面法和雷达剖面法。钻探现场调查将作为多所大学先进的近地表地球物理野外夏令营和研讨会的一部分进行。该营地还将被用作产业-大学-政府在SAFOD项目上合作和互动的中心。该夏令营将主要包括来自杜克大学、斯坦福大学和加州大学伯克利分校的学生，但也将向Questa College Cal Poly San Luis Obispo和其他参与SAFOD努力的机构的学生开放。野外训练营的教育目的有两个：1)展示3D地球物理测量和数据的技术和价值；2)让一大群学生熟悉SAFOD计划的科学目标和研究可能性。通过在每个参与机构之间以开放和协调的方式共享数据，希望出现几个相互竞争的钻探现场模型，最终测试由钻探本身提供。
