This award will provide one-half of the funds required to construct a low magnetic induction space in which to house a magnetometer for measuring the magnetic properties of rocks and minerals. The low magnetic induction space is needed to provide a very low magnetic background for measuring the weak magnetization of small geological samples in the Department of Geology at the University of New Mexico. The University is committed to providing the other half of the funds required. Paleomagnetism involves the study the Earth's past magnetism as it is frozen into rocks and minerals that have cooled at known dates in the Earth's history. The intensity and orientation of the Earth's magnetic field in the past helps us to understand the nature of the internal processes that give rise to the geomagnetic field and to reconstruct its past variations, including field reversals.

这项合同将提供建造低磁感应空间所需资金的一半，在该空间内放置用于测量岩石和矿物磁性的磁强计。新墨西哥大学地质系需要低磁感应空间来提供非常低的磁背景，以测量小地质样品的弱磁化程度。该大学承诺提供所需资金的另一半。古地磁学涉及研究地球过去的磁性，因为它被冻结成岩石和矿物，在地球历史上的已知日期冷却。过去地球磁场的强度和方向有助于我们理解产生地磁场的内部过程的本质，并重建其过去的变化，包括场逆转。
