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

ABSTRACTOCE-9819181海洋初级生产不仅对海洋生态系统的功能很重要，而且在调节二氧化碳（最重要的大气温室气体）海气交换方面也发挥着关键作用。 在这项研究中，主要研究人员将采用间接方法，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年净氧气产量。 该时间序列站位于北太平洋生物生产力最高的区域，氧通量估计值预计将为该区域初级生产提供第一个良好的估计值。 PI 将利用一个独特的机会参加 1998 年至 2000 年间日本 JGOFS 在该地区的航行。

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.
