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.

海洋初级生产不仅对海洋生态系统的功能至关重要，而且在调节大气中最重要的温室气体——二氧化碳的海气交换中也起着关键作用。在这项研究中，首席研究员将采用间接方法，通过测量日本联合全球海洋通量研究（JGOFS）时间序列站的11个海洋上层O2、N2和Ar浓度剖面，来确定西北太平洋的年净氧气产量。该时间序列站位于可能是北太平洋生物生产力最高的区域，预计氧通量估计数将提供关于区域初级产量的第一个可靠估计数。海军陆战队将利用这一独特的机会，参加1998年至2000年期间日本JGOFS在该地区的巡航。
