The project will use the submersible ALVIN and the AUV SENTRY to obtain samples on-and off-axis at the intermediate-spreading Galapagos Spreading Center to study the effects of variable magma supply on volcanic processes at the intermediate-spreading Galapagos Spreading Center. The project will obtain important new constraints on the relationships between magma supply, magma chamber properties and processes, eruption dynamics and the development of volcanic landforms at this intermediate-spreading mid-ocean ridge.

该项目将使用潜水ALVIN和AUV哨兵在中间散布的加拉帕戈斯散布中心在离轴上获取样品，以研究可变岩浆供应对中间扩展的加拉帕戈斯散布中心的火山过程的影响。该项目将对岩浆供应，岩浆腔室性质和过程，喷发动力学以及在这种中间范围内的中间山脊上的火山地面的发展之间获得重要的新约束。
