Our understanding of mid-ocean ridge hydrothermal systems is based on a few measurements of temperatures of the water and compositions of the fluids. The value of these measurements can be extended by simulating the hydrothermal process with computer models that are based on the physics of fluid transport and heat transfer. The PIs have developed computer models for this purpose and wish to extend them to include the effects of crack formation. These models will attempt to duplicate changes in temperature and fluid chemistry that have been observed. In particular they will try to match chemical and temperature measurements at the TAG hydrothermal field with their computer models of the structure and water flow in the mound.

我们对大洋中脊热液系统的了解是基于对水温和流体成分的一些测量。 这些测量的价值可以通过利用基于流体传输和传热物理学的计算机模型模拟热液过程来扩展。 PI为此开发了计算机模型，并希望将其扩展到包括裂缝形成的影响。 这些模型将试图复制已经观察到的温度和流体化学变化。 特别是，他们将试图将TAG热液场的化学和温度测量结果与土丘中结构和水流的计算机模型相匹配。
