Seawater carbonate chemistry and physiological tipping point of sea urchin larvae in a laboratory experiment

In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne and Gattuso, 2011) 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 by seacarb is 2013-12-18.

为实现与其他海洋酸化数据集的全面可比性，我们采用R软件包seacarb（Lavigne与Gattuso，2011）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等人（2010）的研究。本数据集不仅归档了原始观测值，还附带了经重新计算得到的参数（详见相关项目负责人（Principal Investigator，PI））。采用seacarb完成碳酸盐化学计算的日期为2013年12月18日。
