Low Molecular Weight Carbonyls in Seawater: Formation via Photochemical Processes and Role in the Chemistry of Humic Substances

这是对海水中低分子羰基化合物的研究。这些化合物很重要，因为它们参与了海洋中的许多生物和非生物过程，包括地表水中的光化学转化、气-海交换、缩合反应、表面微层浓缩和微生物转化。这项研究将侧重于实验室调查，旨在促进对该项目过去的实地工作的解释。这些研究将包括光化学反应途径、作用光谱、反应物和氧化剂的实验。在这些实验中，将使用低相对分子质量的羰基化合物作为化学探针。除了这项实验室工作外，还将开发和测试上层混合层中的羰基分布模型。

This is a study of low molecular weight carbonyl compounds in sea water. These compounds are important because they are involved in many biotic and abiotic processes in the ocean, including photochemical transformations in the surface water, air-sea exchange, condensation reactions, surface microlayer enrichment and microbial transformations. The research will be focused on laboratory investigations designed to facilitate interpretation of the project's past field work. These investigations will include experiments on photochemical reaction pathways, action spectra, reactants, and oxidants. In these experiments low molecular weight carbonyl compounds will be used as chemical probes. In addition to this laboratory work, a model of the carbonyl distribution in the upper mixed layer will be developed and tested.
