海洋大气化学及其观测工程技术展望

Prospect of marine atmospheric chemistry and its observing engineering technologies

  • 摘要: 海洋大气化学是一门海洋化学与大气化学交叉的新兴学科,是研究海洋大气中化学物种(Chemical Species)含量、迁移变化、来源辨别及海气交换通量,以及预估人为和自然影响对全球气候变化和区域海洋生态系统影响的科学。海洋大气化学的进步也得益于海-气系统观测体系建设及其工程技术的创新,其中包括对微量要素的测量、复杂形态的辨别和原位探测等技术的突破。我国的海洋大气化学研究起步于20世纪80年代,通过中国沿海观察站、近海和大洋走航线和断面站以及南北极建立考察站等的立体观测平台,针对海洋大气化学关键过程即大气海洋生物地球化学循环,开展碳、氮、硫、磷、铁等的迁移变化及其海气通量的观测。在碳、氮的海-气循环及海洋酸化机制,硫的海-气交换的气粒转化及气候效应等研究领域,取得了一批新的认知和引起国际学界关注的成果,促进了学科进步,建成了一个从近岸、大洋到极区的立体观测体系。

     

    Abstract: Marine atmospheric chemistry is a frontier interdisciplinary which combines marine chemistry and atmospheric chemistry. It is a science to study the constitutions, transportation dynamics, sources and sinks as well as seaair fluxes of chemical species in the oceanatmosphere system, and to distinguish and predict the impact of manmade and natural effects on global climate change and regional marine ecosystems. The progress of marine atmospheric chemistry has also benefited from the development of the seaair observation system and engineering technology innovations, including the measurements of trace elements, the determination of complex forms and the in situ monitoring. Marine atmospheric chemistry science in China took the first step in 1980s. Succeed in the establishments of coastal observation stations in China, offshore and ocean investigation and crosssectional underway surveys, the Antarctic and Arctic stations, China has built up a stereoscopy system for the observations of marine atmosphere chemistry key process, such as the atmospheremarine biogeochemical cycle, carbon, nitrogen, sulfur, phosphorus and iron and their seaair fluxes. With the achievements in the study of seaair cycle of carbon and nitrogen and ocean acidification, seaair exchange and gas to particle transformation as well as climate effect of sulfur, China has updated a bath of knowledge that attracted the concerns from the international communities. The built up of a large scale observing network covering the areas from near shore to ocean and the polar regions has also made progress in this fields.
