(Table 3) Temporal variations in areal nitrogen fixation rate from monthly sampling in 2006-2007 at stations TB200 and TB1000 west of Herzelia

Areal rates were calculated from 15N2 uptake measurements for at least four depths (three replicates per depth) and integrated from surface to 150 m depth. Also presented are isotopic compositions (d15N) of particulate matter averaged from non-spiked samples at the four depths (n= 8 per month).

单位面积速率通过至少四个深度层的15N2摄取（15N2 uptake）测量数据计算得到，并对该速率从表层至150米水深进行了积分，每个深度层设置三次重复实验。本数据集同时给出了四个深度层未加标样本的颗粒物d15N同位素组成的月平均结果，每月样本量为8（n=8 per month）。
