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.

本项目的目标是设计、建造和测试一台短基座深海倾斜仪。该计划将涉及对陆基系统中经过验证的组件进行改编，以用于海底地震仪。主要目标是评估(并降低)万向节安装和不同的接地耦合方法所产生的噪音。如果我们要更全面地了解在大洋中脊火山形成新地壳的侵入和喷出过程，我们需要对这些过程进行更直接的观察。获得必要观测的最有成效的技术之一是利用仪器网络测量地面变形--特别是倾斜。这个项目是发展这样一个网络的第一步。
