This award provides one-third of the funds required to purchase and install a large-volume, high-pressure-temperature cubic-anvil press capable of sustained operation up to 200 kilobars and 1500 degrees celsius. The equipment will be housed and operated in the Institute of Geophysics at the University of Hawaii. The University is committed to one-third funding and the Keck Foundation will provide the remaining one-third. Research plans for the facility include: (1) determination of equations of state, phase transitions, and kinetic studies on materials of the Earth's upper mantle, (2) measurement of electrical conductivity and seismic wave propagation velocity of mantle material as a function of degree of partial melting under reproduced upper mantle conditions of pressure and temperature.

该合同提供了购买和安装一台能够持续运行到200千巴和1500摄氏度的大容量、高压温度的三面顶压机所需资金的三分之一。这些设备将被安置在夏威夷大学地球物理研究所并进行操作。该大学承诺提供三分之一的资金，凯克基金会将提供剩余的三分之一。该设施的研究计划包括：(1)确定状态方程、相变和地球上地幔物质的动力学研究；(2)测量在重现的上地幔压力和温度条件下，地幔物质的电导率和地震波传播速度随部分熔融程度的变化。
