Nitrification Rates and Controls: The Deep Oligotropic Nitrogen Cycle

硝化速率与控制：深层寡氮循环水.柱硝化(NH.3.N0.2和N0..2..N0&GT；0.3)是PON/DON的关键生物地球化学汇，也是新初级产品N0.3的来源。直接测量这些速率将需要在(1)测量底物水平，(2)检测孵化过程中的微小变化，以及(3)原位&gt；孵化技术方面取得进展。地下再矿化区的第一个实际硝化速率将使用新的1.5N…1.80.2双重标记同位素技术。N0.2的自然氧化速率将由示踪剂水平1.5N1.80..2到1.5N1.80.3的变化确定，同位素稀释度为1..5N1.8.0.2和ıN0.2！熔池大小的变化将给出NH.3到2的氧化速率。Time.Course&gt；原位孵化公司将使用改进的Taylor/Doherty潜水孵化装置(SID)...

Nitrification Rates and Controls: The Deep Oligotropic NitrogenCycle Water.column nitrification (NH.3 .. N0.2 and N0..2 ..

Measuring these rates directly will requireadvances in (1) measuring substrate levels, (2) detecting smallchanges in incubations, and (3) >in situ> incubation technology. The first real nitrification rates in the subsurface Nremineralization region will use new .1.5N..1.80.2 double.labellingisotope techniques.
