1450791BowlesThis grant supports acquisition of superconducting rock magnetometer (SRM) at the University of Wisconsin-Milwaukee (UWM). The SRM will support research and research training in mineral and rock magnetism and paleomagnetism. Fundamental studies in rock magnetism address the physical mechanisms responsible for the acquisition of magnetism by natural mineral phases and the processes through which that magnetism is either recorded with high fidelity or altered by environmental factors. Mineral magnetic investigations have implications for the development of improved materials for use in many industrial applications. Paleomagnetism studies address the behavior of the Earth?s magnetic field through geologic time and have application to understanding the former positions of continents on Earth, the dynamical behavior and evolution of the geomagnetic field and for interpreting past environmental conditions to better constrain the full spectrum of Earth?s past range of climate conditions.Fundamental studies of how magnetic phases acquire magnetization and studies of the historical dynamics of the Earth?s magnetic field based on paleointensity observations as recorded in magnetic phases in rocks and natural volcanic glasses will be supported. The SRM will allow studies of weakly magnetized materials and very small synthesized phases given to the high sensitivity of direct current superconducting quantum interference device (DC-SQUID) on the requested SRM. Such investigations cannot be accomplished with an extant but much less sensitive spinner magnetometer in the investigator?s laboratory. The instrument will be the first of its kind in the state of Wisconsin and will support regional and international collaborations. The investigator will develop instrument control software that will allow for all SRM measurements to be archived and output in a format compatible with a community mineral, rock and paleomagnetism database (MagIC). The SRM will support student research training with a focus on attracting underreprestented students to the geosciences. This support is congruent with NSFs mission of promoting the progress of science and may advance the national prosperity and welfare through promoting student training for careers in the physical sciences.***

1450791Bowles 这笔赠款支持在威斯康星大学密尔沃基分校 (UWM) 购买超导岩石磁力计 (SRM)。 SRM 将支持矿物和岩石磁性以及古地磁学方面的研究和研究培训。 岩石磁性的基础研究涉及天然矿物相获取磁性的物理机制，以及高保真度记录磁性或受环境因素改变磁性的过程。 矿物磁性研究对于开发用于许多工业应用的改进材料具有重要意义。 古地磁学研究通过地质时间来解决地球磁场的行为，并可用于了解地球上大陆以前的位置、地磁场的动力学行为和演化，以及解释过去的环境条件，以更好地限制地球过去的气候条件范围。磁相如何获得磁化的基础研究以及基于古强度观测的地球磁场历史动态的研究 岩石和天然火山玻璃中记录的磁相将得到支持。 由于直流超导量子干涉装置（DC-SQUID）对所要求的 SRM 具有高灵敏度，SRM 将允许研究弱磁化材料和非常小的合成相。 此类研究无法使用研究人员实验室中现存但灵敏度低得多的旋转磁力计来完成。 该工具将是威斯康星州首个此类工具，并将支持区域和国际合作。 研究人员将开发仪器控制软件，该软件将允许所有 SRM 测量结果以与群落矿物、岩石和古地磁数据库 (MagIC) 兼容的格式存档和输出。 SRM 将支持学生研究培训，重点是吸引代表性不足的学生进入地球科学领域。 这种支持与 NSF 促进科学进步的使命是一致的，并且可以通过促进物理科学职业的学生培训来促进国家繁荣和福利。***
