The U.S. Joint Global Ocean Flux Study is proposing an inquiry into the cycling of carbon and other bioactive elements in the central Equatorial Pacific Ocean. With respect to the upper water column, key objectives include (1) understanding controls on primary production, which appears anomalously low study given the high nutrient concentrations present in the waters; (2) understanding new production in terms of limitations on phytoplankton growth and pathways of carbon cycling within the ecosystems; and (3) studying changes in fluxes and ecodynamics resulting from seasonal and interannual changes in physical forcing. This project will measure net and gross O2 production at 2o N, Oo, and 2o S during cruises in fall, 1991 and spring, 1992. Net production from the change of ıO2! will be measured in samples incubated for 24 hours. Gross production by spiking will also be measured in seawater samples with H218O and measuring the production rate of 18O - labelled O2.

美国联合全球海洋通量研究正在提出一项调查， 碳和其他生物活性元素的循环 赤道太平洋中部 相对于上 水柱，主要目标包括（1）了解控制 在初级生产方面， 沃茨中营养盐浓度高;（2） 了解新产品的局限性， 浮游植物生长和碳循环途径 生态系统;以及（3）研究通量和生态动力学的变化 由于季节性和年际变化的物理 强迫。 该项目将测量2 o N时的净和总O2产量， 在1991年秋季和1992年春季的巡航中，Oo和2 o S。 净 从<$O2的变化生产！将在样品中测量 孵育24小时。 通过扣球的总产量也将是 测量海水样品中的H218 O和测量 18 O标记O2的产生速率。
