Funds are requested for the acquisition of a state-of-the-art Alternating Gradient Force Magnetometer (AGFM) to increase the research and training capabilities of the new Paleo- and Environmental Magnetism Laboratory of the Institut des sciences de la mer de Rimouski (ISMER) at the Université du Québec à Rimouski (UQAR). This instrument measures the magnetic moment of marine or lacustrine sediments, induced or remanent, as a function of magnetic field strength at room temperature. It is widely used to derive hysteresis parameters such as saturation magnetization, saturation remanence, coercivity and coercivity of remanence. These parameters are essential in paleomagnetism to determine the magnetic grain size and mineralogy of sediment samples. The requested instrument will allow the identification and characterization of the natural remanent magnetization carriers in the sedimentary sequences studied as part of the funded and proposed research programs on Quaternary geomagnetic field dynamics, climatic changes and natural hazards, as well as for the training of highly qualified personnel.

请拨资金购买最先进的交流梯度力磁强计，以加强魁北克大学里穆斯基科学研究所新的古与环境磁性实验室的研究和培训能力。该仪器测量海洋或湖泊沉积物的磁矩，无论是诱导的还是残留的，作为室温下磁场强度的函数。它被广泛应用于求取饱和磁化强度、饱和剩磁、矫顽力和剩磁矫顽力等磁滞参数。这些参数在古地磁中对确定沉积物样品的磁性颗粒大小和矿物学是必不可少的。所要求的仪器将允许识别和表征沉积序列中的自然剩余磁化载体，这是第四纪地磁场动力学、气候变化和自然灾害研究方案的一部分，并用于培训高素质人员。
