Seawater carbonate chemistry in a decoupled DIC-pH laboratory experiment

Calcification, respiration and photosynthesis of the widespread diatom-bearing Larger benthic foraminifer Operculina ammonoides were measured in laboratory experiments that included manipulation of carbonate chemistry parameters. pH was altered while keeping Dissolved Inorganic Carbon (DIC) constant, and DIC was altered while keeping pH constant. The data set contains alkalinity, pH and oxygen measurements with calculations of calcification, carbonate chemistry parameters, photosynthesis and respiration. excel sheet 1: natural sea water results. excel sheet 2: pH-DIC manipulated water results.

本研究对广泛分布的具有硅藻的底栖有孔虫Operculina ammonoides的钙化、呼吸和光合作用进行了实验室实验测量，实验中操控了碳酸盐化学参数。在保持溶解无机碳（DIC）恒定的条件下，调节pH值，而在保持pH值恒定的条件下，改变DIC。数据集包含碱度、pH值和氧气测量值，以及钙化、碳酸盐化学参数、光合作用和呼吸的计算结果。Excel表1：自然海水结果。Excel表2：pH-DIC操控水结果。
