Hydrochemistry measured on water bottle samples at station B5/87_288 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.

用于二氧化碳分压（pCO₂）测量的是约0.5升与样品平衡的空气。样品体积为4。营养盐样品收集于250毫升经酸洗的软质低密度聚乙烯（low density polyethylene）瓶中。若采样后未立即进行分析，则将其冷藏至分析时；否则，样品于-20℃下储存。
