Pre-Drilling Magnetic and Gravity Survey of Novarupta, Katmai, Alaska

这个项目是一个大型多机构的一小部分 项目（NSF、USGS、DOE）涉及Katmai的科学钻探 阿拉斯加的国家公园。 根据目前的设想， 将提供钻井资金，所有三个机构将 分担相关科学的费用。 实际钻探是 1990年才开始（视资金到位情况而定） 但有一些钻前调查， 将进行，以定位钻孔在 最佳位置，以实现该项目的科学目标。 该奖项将提供资金进行三项实验， 试图确定1912年诺瓦鲁普塔火山口的地下尺度 为准备拟议的钻探：（1）重新解释 现有航磁和地基磁测数据;（2） 获取新的磁测数据，以填补关键空白; (3)对诺瓦鲁普塔洼地进行了详细的微重力测量 （火山口？）

This project is a small piece of a large multi-agency project (NSF,USGS,DOE) involving scientific drilling in Katmai National Park, Alaska. As envisioned at the present time, DOE will provide the drilling funds, and all three agencies will share in the cost of the associated science. Actual drilling is not to start until 1990 (subject to the availability of funds in DOE) but there are a number of predrilling investigations that will be carried out in order to site the drill holes in the optimum locations to achieve the scientific goals of the project. This award will provide funds to carry out three experiments to try to define the subsurface dimension of the 1912 Novarupta vent in preparation for the proposed drilling: (1) reinterpretation of existing aeromagnetic and ground-based magnetic survey data; (2) the acquisition of new magnetic data to fill critical gaps; and (3) a detailed micro-gravity survey of the Novarupta depression (caldera?).
