Assessing the influence of ocean alkalinity enhancement on a coastal phytoplankton community - manuscript data

The effect of ocean alkalinity enhancement on a coastal phytoplankton community was assessed via a microcosm experiment. The effect of alkalinity enhancement in two scenarios (i) when enclosed seawater was in equilibrium with atmospheric CO2 and (ii) when enclosed seawater was not in equilibrium with atmospheric CO2 were explored. Alkalinity was increased by ~497 umol/kg in these two treatments and plankton communities, carbonate chemistry, dissolved inorganic nutrients, particulate matter and chlorophyll a dynamics monitored over a 22 day period where a spring bloom occurred.

本研究通过微宇宙实验评估了海洋碱度增强对沿海浮游植物群落的影响。研究探讨了两种情景下碱度增强的效应：（i）封闭海水与大气CO₂处于平衡状态时；（ii）封闭海水与大气CO₂未处于平衡状态时。在这两种处理中，碱度提升约497微摩尔/千克，并对浮游植物群落、碳酸盐化学特征、溶解性无机营养盐、颗粒物及叶绿素a的动态变化进行了为期22天的监测，期间发生了春季水华。
