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

该项目是一个大型多机构项目（NSF、USGS、DOE）的一小部分，涉及阿拉斯加卡特迈国家公园的科学钻探。 按照目前的设想，能源部将提供钻探资金，所有三个机构将分担相关科学费用。 实际钻探要到 1990 年才会开始（视能源部的资金情况而定），但将进行大量钻前调查，以便将钻孔定位在最佳位置，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 Novarupta 喷口的地下尺寸，为拟议的钻探做准备：（1）重新解释现有的航空磁力和地面磁力勘测数据； (2) 获取新的磁数据以填补关键空白； (3) 对诺瓦鲁普塔凹陷（破火山口？）进行详细的微重力调查。

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?).
