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.

该赠款支持购置超导岩石磁力计，配置用于对取自沉积物岩心标准剖面的1.5 m u通道进行高空间分辨率（平均间隔为4.5 cm）磁测量。 利用最近开发的脉冲管制冷机的2-G企业SRM系统将消除对液氦冷却到超导温度的需要。 该仪器将支持NSF资助的研究，由俄勒冈州州立大学（OSU）海洋与大气科学学院（COAS）的教师和学生进行。 全新世和更深时间地磁场行为的研究（例如，反转、偏移和古强度）、磁性地层学、构造学和环境古地磁学。 SRM将为更广泛的地球科学界提供服务，用于对俄勒冈州国家海洋地质储存库保存的沉积物进行磁性测量，并用于研究从综合大洋钻探计划和国际大陆钻探计划中回收的岩心。 该仪器将是美国西海岸的第一台此类仪器，收集的数据将通过社区数据库（MagIC）提供。 PI担任OSU荣誉独立学习计划，哈特菲尔德海洋科学中心REU计划和美国原住民海洋和空间科学计划的导师。
