Observed and modeled diazotroph nifH abundances in the global ocean

We supplemented the dataset presented in Luo et al. (2012) "Database of diazotrophs in global ocean: abundance, biomass and nitrogen fixation rates" with measurements of nifH genes using qPCR from 17 additional publications. This addition represents a 141% and a 118% increase in the number of depth-integrated and volumetric data points compared to the database of Luo et al. (2012). This new database includes 223 (1428), 253 (1575), 226 (1424) and 144 (958) observations of depth-integrated (volumetric) abundances of Trichodesmium, UCYN-A, UCYN-B and Richelia, respectively. […]

我们对Luo等人（2012年）“全球海洋固氮微生物数据库：丰度、生物量和固氮速率”中提出的数据集进行了补充，通过qPCR技术对17篇额外文献中的nifH基因进行了测量。此次补充使得数据集的深度积分和体积数据点数量相比Luo等人（2012年）的数据库分别增加了141%和118%。新的数据库中包含了223（1428）、253（1575）、226（1424）和144（958）个关于Trichodesmium、UCYN-A、UCYN-B和Richelia的深度积分（体积）丰度的观测值。...
