Hydrochemistry measured on water bottle samples at station B10/87_548 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）测量的空气体积约为0.5升，该空气需与待测样品达到气液平衡。样品体积为4。营养盐样品采集于经酸洗处理的250毫升软质低密度聚乙烯（low density polyethylene）瓶中。若采样后未立即开展分析，则将样品冷藏保存直至检测；否则，样品需保存于-20℃环境中。
