Intracellular pH (pHi) data collected as part of a study of pCO2 variability on the reef-building coral Pocillopora damicornis conducted at Heron Island Research Station, Heron Island, southern Great Barrier Reef in 2021

This dataset contains intracellular pH (pHi) data. These data were published in Brown et al. (2022).

Abstract for all data from the study (Brown et al., 2022) including this dataset:

Ocean acidification is a growing threat to coral growth and the accretion of coral reef ecosystems. Corals inhabiting environments that already endure extreme diel pCO2 fluctuations, however, may represent acidification resilient populations capable of persisting on future reefs. Here, we examined the impact of pCO2 variability on the reef-building coral Pocillopora damicornis originating from reefs with contrasting environmental histories (variable reef flat vs. stable reef slope) following reciprocal exposure to stable (218 ± 9) or variable (911 ± 31) diel pCO2 amplitude (μtam) in aquaria over eight weeks. This study measured: growth (net calcification, extension, CaCO3 density) and physiology (dark respiration, light-enhanced dark respiration, host soluble protein, mycosporine-like amino acids, net photosynthesis, photosynthetic efficiency, endosymbiont density, chlorophyll a concentration, intracellular pH) of P. damicornis across treatment and origin.

本数据集包含细胞内pH（intracellular pH, pHi）数据，相关研究成果已发表于Brown等人2022年的学术论文中。

该研究（Brown等，2022）涵盖本数据集在内的全部数据的摘要如下：

海洋酸化正对珊瑚生长及珊瑚礁生态系统的加积作用构成日益严峻的威胁。然而，栖息于已存在极端昼夜pCO₂波动环境的珊瑚种群，或可成为具备酸化耐受能力、能够在未来珊瑚礁上存续的类群。

本研究针对源自环境背景迥异的礁体（多变礁坪与稳定礁坡）的造礁珊瑚鹿角杯形珊瑚（*Pocillopora damicornis*），在水族箱中开展了为期8周的交叉暴露实验，将其分别置于稳定（218±9 μatm）或多变（911±31 μatm）昼夜pCO₂振幅环境中。

本研究测定了不同处理组及不同种群来源的鹿角杯形珊瑚的多项生长与生理指标：生长指标涵盖净钙化率、延伸速率、碳酸钙密度；生理指标涵盖暗呼吸作用、光增强暗呼吸作用、宿主可溶性蛋白、类菌孢素氨基酸、净光合速率、光合效率、内共生藻密度、叶绿素a浓度以及细胞内pH。
