This grant supports acquisition of of a superconducting rock magnetometer (SRM) configured to make high spatial (averaged at 4.5 cm intervals) resolution magnetic measurement on 1.5 m u-channels taken from standard sections of sediment cores. A 2-G enterprises SRM system that utilizes a recently developed pulsed tube cryocooler will eliminate the need for liquid Helium to cool to superconducting temperatures. The instrument will support NSF funded research by faculty and their students in the College of Oceanic and Atmospheric Sciences (COAS) at Oregon State University (OSU). Research on Holocene and deeper time geomagnetic field behavior (e.g., reversals, excursions and paleointensity), magnetostratigraphy, tectonics and environmental paleomagnetism will be facilitated. The SRM will serve the broader geoscience community for magnetic measurements of sediments held at the Oregon State Marine Geology Repository and for study of cores recovered from the Integrated Ocean Drilling Program and the International Continental Drilling Program. The instrument will be the first of its kinds on the U.S. west coast and data collected will be made available through community databases (MagIC). The PIs serve as mentors for the OSU Honors independent study program, the Hatfield Marine Science Center REU program and the Native Americans in Marine and Space Science Program.

该赠款支持采集配置的超导岩石磁力计（SRM），该磁力计（SRM）配置为在1.5 m U通道上从沉积物岩心的标准部分中获得的1.5 M U通道进行高空间（平均为4.5 cm的间隔）。 使用最近开发的脉冲管冷却器的2-G企业SRM系统将消除液态氦气以冷却至超导温度的需求。 该工具将在俄勒冈州立大学（OSU）的海洋与大气科学学院（COAS）中支持NSF资助的NSF资助研究。 关于全新世和更深层次的地磁场行为的研究（例如，逆转，偏移和古显着），磁层学，构造和环境古磁性将得到促进。 SRM将为更广泛的地球科学社区提供磁性测量，以磁性测量在俄勒冈州海洋地质存储库中举行的沉积物，并研究从综合海洋钻井计划和国际大陆钻探计划中回收的核心。 该乐器将是美国西海岸的第一个此类工具，收集的数据将通过社区数据库（魔术）提供。 PI是OSU荣誉独立研究计划，Hatfield Marine Science Center REU计划和海洋和太空科学计划中的美洲原住民的导师。
