Coral physiology and intracellular pH (pHi) 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 coral physiology and 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 (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.

本数据集包含珊瑚生理学与细胞内pH（pHi）数据，相关数据采集自2021年在大堡礁南部赫伦岛研究站（Heron Island Research Station）开展的一项关于造礁鹿角杯形珊瑚（Pocillopora damicornis）的二氧化碳分压（pCO2）变异性研究（Brown等人，2022）。

该研究（Brown等人，2022）包含本数据集在内的所有数据的摘要如下：
海洋酸化正对珊瑚生长及珊瑚礁生态系统的钙化过程构成日益严峻的威胁。然而，栖息于已经历极端昼夜pCO2波动环境的珊瑚种群，或许具备酸化耐受能力，有望在未来珊瑚礁生态系统中存续。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）的造礁鹿角杯形珊瑚（Pocillopora damicornis），在水族箱中开展为期8周的交互暴露实验，分别施加稳定（218 ± 9）或多变（911 ± 31）昼夜pCO2振幅（μatm，原文疑似笔误为μtam）。研究测定了不同处理组与珊瑚来源组的鹿角杯形珊瑚的多项指标：生长指标（净钙化率、伸展速率、碳酸钙密度）与生理学指标（暗呼吸作用、光增强暗呼吸、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、细胞内pH）。
