9520528 Brown Research in the Paleomagnetic Laboratory at the University of Massachusetts has been underway for the last twenty years, with emphasis on studies of the paleosecular variation of the Earth's magnetic field and on the solution of geologic problems using paleo-magnetism. Current and past research have been done using measurements from a spinner magnetometer. With the increasing numbers of samples needed for both paleosecular variation and tectonic studies, and the detailed demagnetization steps required with current standards, measurements such as these are a lengthy process. This grant provide funds for the acquisition of a cryogenic magnetometer that will allow for the accurate processing of weakly magnetized sediment samples, as well as radically decrease measurement times. The active Quaternary research group at the University of Massachusetts will now have a paleomagnetic laboratory that is capable of competitive research into paleosecular variation studies on recent sediments and paleoclimatic studies of weakly magnetized materials. The new instrument will also benefit a larger, five-college Quaternary Research Group composed of faculty from Amherst, Hampshire, Mount Holyoke and Smith as well as the host institution. ***

小行星9520528 马萨诸塞州大学古地磁实验室的研究工作已经进行了20年，重点是研究地球磁场的古长期变化和利用古地磁学解决地质问题。目前和过去的研究都是使用旋转磁力计进行测量的。 随着古地磁变化和构造研究所需样品数量的增加，以及现行标准所需的详细退磁步骤，诸如此类的测量是一个漫长的过程。 这笔赠款为购置低温磁力计提供了资金，该磁力计将能够准确处理弱磁化沉积物样品，并从根本上减少测量时间。 马萨诸塞州大学活跃的第四纪研究小组现在将拥有一个古地磁实验室，能够对近期沉积物的古长期变化研究和弱磁化物质的古气候研究进行竞争性研究。 新仪器也将有利于一个更大的，五个学院第四纪研究小组组成的教师从阿默斯特，汉普郡，山霍利奥克和史密斯以及主办机构。 ***
