Acquisition of Basic Environmental Magnetics Laboratory Equipment

[01:10840]这项设备拨款为俄亥俄州阿克伦大学的环境磁学实验室提供了部分支持。现有的环境磁学实验室包含一个Molspin旋转磁力计，ASC脉冲磁化器和巴丁顿磁化设备。这项提议和阿克伦大学的费用分摊将用于通过购买D-Tech型号D-2000 AF消磁器、2.5 m3磁通门控制的无场笼、Micromag交变梯度磁力计和额外的巴丁顿磁化率传感器来建立一个功能完备的实验室。该设备的添加将允许测量湿沉积物的全套环境磁参数。环境磁性的岩石磁性成分涉及沉积物磁性部分的浓度、粒度和矿物学的测量，并用于解释过去的环境变化。环境磁学的古磁学成分涉及对沉积物自然剩余磁化的研究，并提供全球地层对比、测年和对地球动力学过程的了解的手段。目前在蒙古、非洲、俄罗斯和土耳其的nsf资助项目将有效利用这种设备。在PI John Peck的指导下，NSF正在进行的研究项目涉及对蒙古湖泊、加纳博苏姆特维湖和俄罗斯贝加尔湖沉积物中记录的过去环境变化的研究。Drs。来自阿克伦大学的Lisa Park， Ira Sasosky和Tim Matney将分别在非洲的古湖泊学，土耳其的考古学和美国的碎屑洞穴沉积物研究中使用该设备。附近大学的研究人员和学生将可以免费使用这些新设备，从而使他们能够在研究中随时使用这些设备。附近的肯特州立大学、凯斯西储大学和奥伯林学院的地质学家都表示有兴趣使用该地区的新设备。此外，新设备将服务于教育目标，并广泛用于由PI， Peck.***教授的名为“环境磁学”的新地质学课程

0110840PeckThis equipment grant provides partial support to enhance an environmental magnetics laboratory at the University of Akron, Ohio. The existing environmental magnetics laboratory contains a Molspin spinner magnetometer, ASC Impulse magnetizer and Bartington susceptibility equipment. This proposal and cost sharing from the University of Akron will be used to establish a fully-functional laboratory through the acquisition of a D-Tech Model D-2000 AF demagnetizer, 2.5 m3 fluxgate-controlled field-free cage, Micromag alternating gradient magnetometer, and additional Bartington susceptibility sensors. The addition of this equipment will allow the full suite of environmental magnetic parameters of wet sediment to be measured. The rock-magnetic component of environmental magnetism involves the measurement of the concentration, grain-size, and mineralogy of the magnetic portion of the sediment and is used to interpret past environmental change. The paleomagnetic component of environmental magnetism involves the study of the natural remanent magnetization of the sediment and provides a means of global stratigraphic correlation, dating, and insight on geodynamo processes. Current NSF-funded projects in Mongolia, Africa, Russia and Turkey will make effective use of this equipment. Ongoing NSF research projects directed by PI, John Peck involve the study of past environmental change as recorded in the sediments of Mongolian lakes, Lake Bosumtwi, Ghana and Lake Baikal, Russia. Drs. Lisa Park, Ira Sasosky and Tim Matney from the University of Akron will use this equipment in their research of paleolimnology in Africa, archaeology in Turkey and clastic cave deposits in the U.S., respectively. Researchers and students from nearby Universities will have free-access to this new equipment thereby allowing them to readily utilize this equipment in their research. Geologists at nearby Kent State University, Case Western Reserve University and Oberlin College have all expressed their interest in using this equipment that is new to the region. In addition, the new equipment will serve educational goals and be used extensively in a new Geology course titled Environmental Magnetism taught by PI, Peck.***
