Investigation of Total Alkalinity during an artificially induced phytoplankton spring bloom@en

To investigate links between biological, biogeochemical and physical parameters, we closely monitored an artificially induced spring bloom. Our mesocosm approach mimicked a neritic North Sea water body. Three biological replicates (P2-P4) were inoculated with a phytoplankton and associated bacterial community, which was retrieved in March 2018 from the southern North Sea. The incubation was monitored for 38 days. The experiment additionally covered the investigation of two biota-free controls. A variety of parameters were sampled, the results of some can be found in Mori et al. (2021; doi:10.1016/j.gca.2021.08.002). […]为探究生物学、生物地球化学与物理参数间的关联，我们对人工诱导的春季水华开展了全程严密监测。本研究采用中宇宙（mesocosm）实验体系，模拟北海水域的近岸水体环境。以2018年3月取自北海南部的浮游植物及其伴生细菌群落为接种物，设置3组生物学重复（P2-P4）。整个培养周期持续38天并全程监测，本实验还额外设置两组无生物对照开展相关研究。实验采集了多类参数的样本，其中部分研究结果已发表于Mori等人（2021；doi:10.1016/j.gca.2021.08.002）。[…]
