<0= below detection limits. In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne et al, 2014) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation is 2014-08-21.<0 表示低于检测限。为确保与其他海洋酸化数据集具备全面可比性，本数据集采用R软件包seacarb（Lavigne等，2014）计算得到一套完整且一致的碳酸盐系统变量，具体方法参照Nisumaa等（2010）的研究。本数据集同步存档了原始观测值与经重新计算的参数（详见相关PI）。碳酸盐化学参数的计算日期为2014年8月21日。
