This three-year award for U.S.-France cooperative research in geophysics involves Peter L. Olson of Johns Hopkins University and Jean-Claude Nataf of the Ecole Normale Superieure in Paris, France. They propose to conduct a series of fluid dynamics experiments using liquid galium. The objective is to understand the dynamics of the Earth's core, including the operation of the geodynamo, and to eventually build an experimental model of the geodynamo. They will investigate thermochemical convection in liquid gallium subjected to the combined influences of rotation and magnetic fields and study the crystallization of gallium alloys in the presence of convection, rotation and magnetic fields. The project takes advantage of similar experiments conducted by the French group and provides access to excellent facilities in France.

约翰·霍普金斯大学的彼得·L·奥尔森和法国巴黎高等学院的让-克洛德·纳塔夫获得了这项为期三年的地球物理学合作研究奖。他们建议使用液态镓进行一系列流体力学实验。其目的是了解地球核心的动力学，包括地球发电机的运行，并最终建立一个地球发电机的实验模型。他们将研究在旋转和磁场的共同影响下液态镓中的热化学对流，并研究在对流、旋转和磁场存在下镓合金的结晶。该项目利用了这家法国集团进行的类似实验，并提供了进入法国优秀设施的途径。
