Recent works have begun to explore the magnitude and frequency of localized changes in seawater chemistry in shallow water systems, where the effects of warming and acidification are still unpredictable. In a Mediterranean shallow coastal site, we empirically characterized the diel, seasonal, and annual pattern of pH, temperature, and associated chemical changes on one Ellisolandia elongata ‘corniche’, (i.e. a coastal algal biogenic reef). Local benthic metabolism together with temperature, were two of the main drivers for the carbonate system variation over diel and seasonal cycles. During the 12-month study, a total of seven heatwave events were recorded (two of which occurred in winter) with the longest lasting 11 days. The present study highlights the importance of improving the knowledge of changes and dynamics occurring at local scale, by extending in situ data acquisition at shallow coastal sites, in order to better assess the impacts of climate change on both environment and ecosystems.

最近的工作已经开始探索在浅水系统中海水化学的局部变化的幅度和频率，在该系统中变暖和酸化的影响仍然是不可预测的。在地中海的一个浅海沿岸站点，我们根据经验对一只Ellisolandia elongata的pH，温度和相关化学变化的diel，季节性和年度模式进行了表征“海滨大道”（即沿海藻类生物礁）。底栖生物的新陈代谢以及温度是diel和季节周期中碳酸盐体系变化的两个主要驱动力。在为期12个月的研究中，总共记录了7次热浪事件（其中2次发生在冬季），最长持续11天。本研究强调了通过扩展浅海沿岸站点的原地数据采集来提高对地方规模变化和动态的认识的重要性，以便更好地评估气候变化对环境和生态系统的影响。
