Acquisition of Paleomagnetic Equipment for the Department of Earth Sciences, University of New Hampshire

这笔赠款为新汉普郡大学的古地磁实验室的发展提供了部分资金。该实验室将通过三种一般方式加强UNH的研究活动。它将(1)支持PI对磁性地层学的研究，(2)增加新汉普郡大学在地球物理、构造学和地层学方面的其他教职研究项目，以及(3)加强本科生和研究生课程。该实验室将配备一个以鱿鱼为基础的旋转磁强计、一个双室热消磁器、一个交变磁场消磁器和一个三维场补偿线圈系统来容纳和操作这些设备。目前，新英格兰北部还没有能够测量弱磁性沉积物剩余磁化强度的古地磁设备。该实验室将为北卡罗来纳大学及其周边机构的研究人员提供这一能力。PI的初步研究侧重于研究气候和构造变化在哺乳动物进化中所起的作用。这项研究需要有能力在大陆段之间以及大陆段和海洋段之间进行精确的年代地层对比。磁性地层学是实现这一目标最可靠、最适用的方法。北卡罗来纳大学的其他教员将利用该设施加强他们对磁力测量、阿巴拉契亚构造运动、海平面变化和古含水层地层结构的研究。几个本科生和研究生班级也将使用该设施进行动手实验室练习。

0086672ClydeThis grant provides partial funding for the development of a paleomagnetic laboratory at the University of New Hampshire. This laboratory will strengthen research activities at UNH in three general ways. It will (1) support the PI's research into magnetostratigraphy, (2) augment other University of New Hampshire faculty research programs in geophysics, tectonics, and stratigraphy, and (3) enhance the undergraduate and graduate curriculum. The laboratory will be outfitted with a SQUID-based spinner magnetometer, a dual-chamber thermal demagnetizer, an alternating-field demagnetizer, and a three-dimensional field compensation coil system in which to house and operate this equipment.At present there is no paleomagnetic facility in northern New England that is capable of measuring the remanent magnetization of weakly magnetized sediments. This laboratory will provide this capability to researchers at UNH and surrounding institutions. The primary research of the PI focuses on investigating the role that climatic and tectonic changes play in the evolution of mammals. This research requires the ability to make precise chronostratigraphic correlations among continental sections and between continental sections and marine sections. Magnetostratigraphy is the most reliable and applicable method to carry this out. Other faculty at UNH will use the facility to augment their research into magnetic surveying, Appalachian tectonism, eustatic sea-level changes, and the stratigraphic architecture of paleoaquifers. Several undergraduate and graduate classes will also use the facility for hands-on laboratory exercises.***
