中文摘要
翻译
9521258卡斯特纳·卡斯特纳将在海洋重晶石中开发ND同位素，以追踪水团的波动。这项技术应该有助于理解水团的发展及其在冰川-间冰期循环期间的运动。这项研究还应该有助于理解重晶石在水中形成的深度，这一问题已经困扰了一段时间。这一点很重要，因为沉积物中的重晶石已被用来指示地表水的生产力。***
英文摘要
9521258 Kastner Kastner will develop Nd isotopes in marine barite to trace fluctuations of water masses. This technique should be useful in understanding the development of water masses and their movement during glacial-interglacial cycles. This research should also lead to an understanding of what depth barite forms in the water, which has been a puzzle for some time. This is important because barite in sediments has been used to indicate the productivity of the surface waters. ***
