(Table S1) Results of isotope analysis from shells of Mytilus galloprovincialis at the experimental site B1 and control site C@en

Distance from commissure indicates position of sampling point. Aragonitic (nacreous) layer isotope data were normalized against calcite isotope values using the equation of Rubinson and Clayton (1969) for d13C and that of Tarutani et al. (1969) for d18O.采样点距壳连合部的间距用于表征其位置。文石（珍珠质）层的同位素数据以方解石同位素数值为基准开展标准化处理，其中碳同位素δ¹³C的标准化采用鲁宾逊与克莱顿（Rubinson and Clayton，1969）提出的公式，氧同位素δ¹⁸O的标准化则采用塔鲁塔尼等人（Tarutani et al.，1969）提出的对应公式。
