中文简介: | 本课程旨在为学生提供海洋和海洋沉积物中有机物质循环的全球到分子水平视角。主题包括:主要海洋储层中的有机物(C、N、P)组成、反应性和预算,以及流经这些储层的流量;有机物的微生物循环途径;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(下沉和悬浮)器官之间的关系IC物质;沉积有机物的特征描述方法;作为海洋学工具的生物标记的应用。包括结构和同位素方面。 |
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. |
