Development of an Automated Cryogenic Magnetometer Facility for Environmental Magnetic and Paleomagnetic Studies at the University of California - Davis

9413732 Verosub该合同提供了建造仪器系统所需资金的一半，用于对湖泊和海洋沉积物的岩心以及土壤剖面进行连续的高分辨率测量。该系统将在加州大学戴维斯分校地质系安装和运行。该大学承诺提供完成该项目所需的剩余资金。当磁性矿物颗粒在安静的条件下以沉积物的形式沉积在水体底部或结合在发育中的土壤剖面中时，颗粒平行于地磁场排列，它们的排列稍后可用于破译沉积物或土壤剖面积累所代表的时间段内磁场的过去历史。新仪器的主要目标将是利用沿沉积物岩心长度测量的磁参数的变化来获得对气候变化的连续解释。该设施的一个补充科学目标将是获得地球磁场行为的历史，包括磁场方向和强度的变化。***

9413732 Verosub This award provides one-half the funding required to construct an instrument system for making continuous high- resolution measurements of cores of lake and marine sediments and of soil profiles. The system will be installed and operated in the Department of Geology at the University of California-Davis. The University is committed to providing the remaining funds required to complete the project. When magnetic mineral grains are deposited as sediment at the bottom of water bodies under quiet conditions or become incorporated in developing soil profiles, the grains are aligned parallel to the geomagnetic field, and their alignment can later be used to decipher the past history of the magnetic field during the time represented by the accumulation of the sediment or soil profile. The primary goal of the new instrumentation will be to obtain continuous interpretations of climate change using the variation of magnetic parameters measured along the length of sediment cores. A complementary scientific goal of the facility will be to obtain a history of the behavior of the Earth's magnetic field, including variations in the direction and intensity of the field. ***
