Hydrochemistry measured on water bottle samples at station B8/90_368 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.

对于二氧化碳分压（pCO2）的测量，约需使用0.5升与样品平衡的空气。样品体积为4毫升。营养样品采集于250毫升的软质低密度聚乙烯酸洗瓶中。若未能立即进行样品分析，则需将其冷藏保存。否则，样品应储存在-20°C的温度下。
