Net Biological Oxygen Production at the Japanese JGOFS Time-Series Station

海洋初级生产不仅对海洋生态系统的功能很重要，而且在调节最重要的大气温室气体二氧化碳的海-气交换方面也起着关键作用。在这项研究中，首席研究员将使用一种间接方法，通过测量日本联合全球海洋通量研究(JGOFS)时间序列站上层海洋中O2、N2和Ar浓度的11个剖面，来确定西北太平洋的净氧气年产生量。时间序列监测站可能位于北太平洋生物生产力最高的地区，氧通量估计预计将提供对该地区初级生产的第一个良好估计。国际和平协会将利用一个独特的机会，在1998年至2000年期间参加日本在该地区的JGOFS巡航。

ABSTRACTOCE-9819181Primary production in the ocean is important not only for the functioning of the marine ecosystem but also for its pivotal role in regulating sea-air exchange of carbon dioxide, the most important atmospheric greenhouse gas. In this study, the principal investigator will use an indirect method to determine the net annual oxygen production in the northwest Pacific Ocean by measuring eleven profiles of O2, N2, and Ar concentrations in the upper ocean at the Japanese Joint Global Ocean Flux Study (JGOFS) time-series station. The time-series station is located in what is probably the most biologically productive region of the North Pacific, and the oxygen flux estimates are expected to provide the first good estimates of the regional primary production. The PI will be taking advantage of a unique opportunity to participate in Japanese JGOFS cruises in this region between 1998 and 2000.
