中文简介: | 本课程旨在为学生提供全球到分子水平的海洋和海洋沉积物中有机物循环的视角。主题包括:主要海洋储层中的有机物质(C,N,P)成分,反应性和预算以及通过的通量;微生物回收有机物的途径;有机物降解和保存模型;缺氧在有机物埋藏中的作用;溶解和颗粒物(下沉和悬浮)有机物之间的关系;表征沉积有机物的方法;生物标志物作为海洋学工具的应用。涵盖了结构和同位素两个方面。 |
课程简介: | This class is designed to provide the student with a global to molecular-level perspective of organic matter cycling in the oceans and marine sediments. Topics include: Organic matter (C,N,P) composition, reactivity and budgets within, and fluxes through, major ocean reservoirs; microbial recycling pathways for organic matter; models of organic matter degradation and preservation; role of anoxia in organic matter burial; relationships between dissolved and particulate (sinking and suspended) organic matter; methods for characterization of sedimentary organic matter; and application of biological markers as tools in oceanography. Both structural and isotopic aspects are covered. |
