Development and Testing of a Submarine Tiltmeter for Deformation Measurements at Mid-Ocean Ridges

本课题的目的是设计、制造和测试一种短基深海倾斜仪。该计划将涉及使用来自陆地系统的经过验证的组件，用于海底地震仪。主要目标是评估（并降低）由云台安装和不同的地面耦合方法预期的噪声。如果我们要更全面地了解在洋中脊火山上形成新地壳的侵入和挤压过程，我们需要对这些过程进行更直接的观察。要获得必要的观测资料，最有效的技术之一是用仪器网络测量地面变形，特别是倾斜。这个项目是朝着开发这样一个网络迈出的第一步。

Objective of this project is to design, build and test a short-base deep sea tiltmeter. The program will involve the use of adaptation of proven components from land based systems for use with ocean bottom seismometers. The primary goals are to evaluate (and reduce) noise expected from the gimballed mounting and different methods of ground coupling. %%% If we are to understand more fully intrusive and extrusive processes that create new crust at mid ocean ridge volcanoes, we need to make more direct observations of the processes. One of the most fruitful techniques for obtaining the necessary observations is the measurement of ground deformation--especially tilt--with a network of instruments. This project represents the first step toward developing such a network.
