Hydrochemistry measured on water bottle samples at station B8/90_451 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.

对于二氧化碳分压的测量，约需0.5升与样品平衡的空气。样品体积为4。营养样品收集于250毫升的软质低密度聚乙烯酸洗瓶中。若样品采集后未立即进行分析，则需冷藏保存。否则，样品应储存在-20°C的温度下。
