9414305 Beske-Diehl The PIs will perform an exploratory investigation into the viability of using ESR spectroscopy signatures of volcanic ash and ejecta to determine synchroneity of distributed ash deposits. In this investigation they will first determine whether magnetic properties are uniform throughout distal portions of at least two volcanic tephra units. Next they will determine whether magnetic properties can identify tephra deposits from different eruptions of the sam volcano and from eruptions of different volcanoes by investigating magnetic properties of such tephra units. ****

小行星9414305 PI将对使用火山灰和喷出物的ESR光谱特征来确定分布的火山灰沉积物的同步性的可行性进行探索性调查。 在这次调查中，他们将首先确定至少两个火山碎屑岩单元的整个远端部分的磁性是否均匀。 下一步，他们将通过研究火山碎屑单元的磁性来确定磁性是否可以识别萨姆火山不同喷发的火山碎屑沉积物。 ****
