Hydrochemistry measured on water bottle samples at station A3/88_120 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.

进行二氧化碳分压（pCO2）测定时，需使用约0.5升与样品达到平衡的空气。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瓶中。若采样后未立即开展分析，则样品需冷藏保存直至检测；否则需将样品置于-20℃条件下冷冻存储。
