Hydrochemistry measured on water bottle samples at station B8/90_369 during the MRI-LDEO cooperative study

For pCO2 measurements were about 0.5 liter of air equilibrated with sample. Sample volume 4. Nutrient samples are collected in 250 ml soft low density polyethylene acid washed bottles. They are kept refrigerated until analysis if it was not carried out soon after sampling. Otherwisee samples are stored at -20°C.

二氧化碳分压（pCO2）的测量约为以0.5升空气与样本达到平衡。样本容量为4毫升。营养样本收集于250毫升软质低密度聚乙烯酸洗瓶中。若未在采样后立即进行分析，样本需冷藏保存。否则，样本应储存于-20°C温度下。
