Environmental data, carbonate chemistry and nutrients

To evaluate the influence of episodic extreme ocean acidification events in coastal regions, we deployed eight pelagic mesocosms for 53 days in Raunefjord, Norway, and enclosed 60 m³ of local seawater containing a natural plankton community under post-bloom conditions. Four mesocosms were manipulated to simulate extreme pCO2 levels of 2069 µatm while the other four served as untreated controls. To monitor the effects of extreme pCO2 conditions, a variety of physical, ecological, and biogeochemical parameters inside and outside the mesocosms were measured over the course of the experiment in regular intervals.

为评估沿海区域突发性极端海洋酸化事件的影响，我们在挪威劳讷峡湾（Raunefjord）部署了八个远洋中尺度围隔生态系统（pelagic mesocosms），围隔60立方米含藻华后自然浮游生物群落的当地海水，实验持续53天。其中四个围隔被操控以模拟2069微大气压（µatm）的极端二氧化碳分压（pCO₂）水平，其余四个作为未处理对照。为监测极端二氧化碳分压条件的影响，实验期间定期对围隔内外的多种物理、生态及生物地球化学参数进行了测量。
