Diagenesis and the Exchange of Soluble Substances between the Oceans and the Sediments

对底栖生物过程速率的季节和年际变化、沉积物-水界面物质的循环及其与颗粒通量的关系进行了研究。这项研究试图确定输入到海底的颗粒物的季节变化对沉积物反应的影响、界面上溶解成分的通量、影响沉积物的生物活性以及沉积物中CaCO3的保存。通过这种方式，我们试图评估表层海洋事件对底栖生物速率和过程的影响。所选择的地点在百慕大附近，其特点是在海洋的许多区域发现了条件，这使得得出的结论适用于直接研究区域以外的地方。还提出了在区域尺度上研究影响沉积物中CaC03保存的因素。这些研究集中在评估底水饱和状态和有机质代谢对CaC03沉积后溶解速度和程度的影响。这些研究将在美国东海岸的一个样带上进行。

Studies of seasonal and interannual variations of rates of benthic processes and the cycling of material across the sediment-water interface and their relationship to particle fluxes are proposed. The research seeks to determine the influence of seasonal changes in the input of particulate matter to the sea floor on sediment reactions, fluxes of dissolved components across the interface, biological activity as it affects sediments, and the preservation of CaCO3 in the sediments. In this fashion we seek to evaluate the influence of events in the surface ocean upon benthic rates and processes. The site chosen, off Bermuda, is characterized by conditions found in many areas of the ocean making the conclusions drawn applicable beyond the immediate study area. Research on the factors governing the preservation of CaC03 in sediments on a regional scale is also proposed. These studies are focussed upon evaluating the effects on bottom water saturation state and organic matter metabolism upon rates and the extent of post-deposition dissolution of CaC03. The studies would be carried out on a transect of the east coast of the United States.
