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.

该研究（Brown等，2022）的全部数据（含本数据集）的摘要如下：
海洋酸化正日益威胁珊瑚生长与珊瑚礁生态系统的造礁过程。然而，栖息于已存在极端昼夜pCO₂波动环境的珊瑚种群，或许代表了未来珊瑚礁上能够存续的耐酸化类群。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）的造礁珊瑚杯形珊瑚（Pocillopora damicornis），将其分别置于稳定（218 ± 9 μtam）或可变（911 ± 31 μtam）昼夜pCO₂振幅条件下，开展了为期八周的水族箱互易暴露实验。本研究测定了不同处理组与不同起源礁体的杯形珊瑚的多项生长指标（净钙化率、延伸率、碳酸钙密度）与生理指标（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、内共生体密度、叶绿素a浓度、细胞内pH）。
