Upgrade of Computational Facilities for Geophysics Research and Student Training at Old Dominion University

1623816 georgen地球科学部仪器和设施计划拨款支持购置计算设备，以支持地球物理学和地球动力学的研究和研究培训。资金将允许购买两台带有3.5 GHz六核cpu、64 Gb RAM和双gpu的Mac Pro台式机，以支持更大的数值模型域和更小的网格分辨率，从而更好地模拟具有高时空梯度的地质过程，更好地处理与时间相关的解决方案，以及更高的整体更高的模型吞吐量。鉴于在计算建模技术方面培训下一代科学工作者的重要性以及了解气候变化和海平面对陆地水文水库的影响的社会重要性，这种支持与国家科学基金促进科学进步和促进国家健康、繁荣和福利的使命是一致的。研究将集中在地球动力学建模处理，包括地幔柱？洋中脊相互作用、俯冲带动力学以及海平面变化对中大西洋东部沿岸地下水水文和海底地下水排放的影响。

1623816GeorgenThis Division of Earth Sciences Instrumentation and Facilities Program grant supports acquisition of computational equipment to support research and research training in geophysics and geodynamics. Funding would allow for purchase of two Mac Pro desktops with 3.5 GHz six-core CPUs, 64 Gb RAM and dual GPUs each to support larger numerical model domains and smaller grid resolutions to better model geological processes with high spatial and temporal gradients, better handling of time-dependent solutions, and higher overall higher model throughput. This support is congruent with NSFs mission of promoting the progress of science and advancing the national health, prosperity and welfare given the importance of training the next generation scientific workforce in computational modeling techniques and the societal importance of understanding the impacts of changing climate and sea level on terrestrial hydrologic reservoirs.Research will focus on modeling of geodynamics processed including mantle plume ? mid ocean ridge interactions, subduction zone dynamics and effects of sea level change on groundwater hydrology and submarine groundwater discharge along the eastern Mid-Atlantic shore.
