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?).

该项目是一个大型多机构项目（NSF，USGS，DOE）的一小部分，该项目涉及阿拉斯加卡特梅国家公园的科学钻探。 正如目前所设想的那样，DOE将提供钻探资金，所有三个机构将分享相关科学的成本。 实际的钻探要等到1990年才开始（在DOE中可用的资金可用），但是将进行许多售后调查，以便将钻孔位于最佳位置，以实现该项目的科学目标。 该奖项将为进行三个实验提供资金，以试图定义1912年Novarupta通风口的地下维度，以准备拟议的钻探：（1）重新解释现有的航空磁和地面磁性调查数据； （2）获取新的磁数据以填补关键空白； （3）对Novarupta抑郁症（Caldera？）的详细微分调查。
