The purpose of this project is to study the magnetic properties of sediments deposited under low to no oxygen conditions. The low oxygen conditions will be studied in sedimentary cores from the Panama Basin and the anoxic conditions studied in cores to be taken in summer 1988 in the Black Sea. The chemical processes responsible for the formation of magnetic minerals will be studied and the impact of changes in the chemistry during climatic changes in the two basins will be addressed. The results from this project will provide a basic framework for understanding the chemical remagnetization of sediments; something that has frustrated previous attempts to use the magnetic properties of sub-oxic and anoxic sediments in geological research.

该项目的目的是研究在低氧或无氧条件下沉积的沉积物的磁性。 将在巴拿马盆地的沉积岩心中研究低氧条件，并在 1988 年夏季在黑海采集的岩心中研究缺氧条件。 将研究导致磁性矿物形成的化学过程，并解决两个盆地气候变化期间化学变化的影响。 该项目的结果将为理解沉积物的化学重磁化提供一个基本框架； 这使得之前在地质研究中利用低氧和缺氧沉积物的磁性的尝试受挫。
