Aquatic chemistry: major cations and anions.

a average based on hatching in Fig. 2
b calculated to offset the charge balance error as explained in the methods section
c average based on two samples from 2012. A third sample from 258 m depth taken in 2010 was not included in the averaging, see supplementary S4 Table
– indicates that the sample was not analyzed, or was discarded, for this parameter
± is the standard deviation calculated from layers or sources where more then one sample was analyzed
Aquatic chemistry: major cations and anions.

a：平均值基于图2中的孵化相关结果
b：经计算以抵消方法部分所述的电荷平衡误差
c：平均值基于2012年的两份样本计算得到。2010年采集的、采自258米深度的第三份样本未纳入本次平均计算，详见补充材料表S4
–：表示该参数未对对应样本开展分析，或已将该样本舍弃
±：代表基于多个采样层或采样源的多份分析样本计算得到的标准差
