9521113 Parmentier The Dynamics of Mid-Ocean Ridges Parmentier and Forsyth will continue examining processes at mid- ocean ridges through computer modeling. The models start with simple observations such as: ridges are broken into segments of different length. The computer models use measured and estimated physical properties of the mantle such as viscosity and temperature, and hypotheses about how the mantle will behave to calculate what the length of the ridge segments should be and what parameters affect this length. The results of the models can point to features on the sea floor that can be measured that will confirm alternate model outcomes. The work will lead to a better understanding of the properties the mantle.

9521113 Parmentier中山脊和福赛斯的动力学将通过计算机建模继续检查中脊的过程。模型以简单的观测开始，例如：脊分为不同长度的段。计算机模型使用地幔的测量和估计物理特性，例如粘度和温度，并假设地幔如何表现以计算脊段的长度应该是什么以及哪些参数会影响这一长度。模型的结果可以指向可以测量的海底特征，以确认替代模型结果。这项工作将使对地幔的特性有更好的了解。
