US-India Cooperative Research: A Multibeam Survey of the Equatorial Carlsberg and Central Indian Ridges and Their Fracture Zones, 3N-10S

该合同支持美印合作研究：对赤道嘉士伯和中印度脊及其断裂带3N-10S进行多波束测量。Drs。威斯康星大学麦迪逊分校的D. DeMets、印度国家地球物理研究所的R. K. Drolia和印度国家海洋学研究所的R. Mukhopadhyay将对嘉士伯（CR）和中印度脊（CIR）进行为期3年的多波束和运动学研究。他们将检查印度研究船（R/V Sagar Kanya）收集的多波束数据，研究印度国内研究巡航产生的新数据，并研究使用Sagar Kanya绘制CR和CIR地图的新建议，这项提议的工作是一项广泛而期待已久的研究，将阐明印度洋中部洋脊系统2000公里长的未绘制部分的轴向和转换形态。研究范围：本研究对于在基础水平上掌握板块的行为和建立板块运动框架具有重要意义，这将有助于更好地了解喜马拉雅地质。对中印度洋的研究对脊系统的全球特征至关重要，并将对许多相关领域产生有利影响。美国和印度数据库的合并将使两组科学家受益，并最终导致未来的船上合作项目。科学家们是该领域的领导者，对印度洋脊系统的研究将有助于解决地球物理研究前沿的一些未解之谜。此外，该研究还对气候变化和海洋和大陆地区的地球动力学具有重要意义。本项目由国际科学与工程办公室和海洋科学司共同资助。

0244894DeMetsDescription: This award supports the US-India Cooperative Research: A Multibeam Survey of the Equatorial Carlsberg and Central Indian Ridges and their Fracture Zones, 3N-10S. Drs. D. DeMets, University of Wisconsin, Madison, R. K. Drolia, Indian National Geophysical Research Institute, and R. Mukhopadhyay, Indian National Institute of Oceanography will conduct a 3-year multibeam and kinematic study of the Carlsberg(CR) and Central Indian Ridges(CIR). They will examine multibeam data already collected by the Indian research ship (R/V Sagar Kanya), study new data generated by Indian domestic research cruises, and work on new proposals using the Sagar Kanya to map the CR and CIR. The proposed work is a wide-ranging and long-awaited study that will shed light on the axial and transform morphology of a 2000-km long unmapped section of the mid-ocean ridge system in the Central Indian Ocean. Scope: The proposed research is important for grasping the behavior of plates at the fundamental level and for building a plate kinematic framework that will lead to better understanding of Himalayan geology. Study of the central Indian Ocean is essential for the global characterization of the ridge system and will have favorable impacts on many allied fields. The merging of US and Indian databases will benefit both groups of scientists and eventually lead to future shipboard collaborative programs. The scientists are leaders in the field and this study of the Indian Ocean ridge system will contribute to resolving some major unanswered questions at the forefront of geophysical research. Additionally, this research has implications bearing on climate change and the geodynamics of both oceanic and continental regions. This project is jointly funded by the Office of International Science and Engineering and the Division of Ocean Sciences.
