Ammonium (NH4) data from CTD rosette bottles from R/V Thomas G. Thompson and R/V Kilo Moana cruises TN277, KM1301, KM1312 in the Eastern North Pacific Ocean from 2012-2013 (POWOW project)

<p>Ammonium (NH4) concentration in nM from 3 POWOW cruises (TN277, KM1301, and KM1312). Samples that had a mean concentration (mean of replicated samples) below the nominal detection limit are reported as zero.</p> <p>Also see related inorganic nutrient data from this project.<br /> Nitrite and Nitrate (NO2, NO3)&nbsp;https://www.bco-dmo.org/dataset/3755<br /> Phosphate and Silicate (PO4, SiOH4)&nbsp;https://www.bco-dmo.org/dataset/3756</p>本数据集涵盖TN277、KM1301与KM1312三个POWOW航次的铵态氮（NH4）浓度数据，单位为纳摩尔浓度（nM）。若重复样品的均值低于标称检出限，则该样品的浓度记为零值。 亦可查阅本项目下的相关无机营养盐数据集： 亚硝酸盐与硝酸盐（NO2、NO3）：https://www.bco-dmo.org/dataset/3755 磷酸盐与硅酸盐（PO4、SiOH4）：https://www.bco-dmo.org/dataset/3756
