抽象的。波罗的海的生态系统受到富营养化的威胁。这引发了昂贵的国际管理努力。其中一些努力受到自然过程的阻碍，例如固氮蓝藻水华，它为已经过度施肥的系统增加了生物可利用的氮，从而提高了初级生产，有机物向深处的出口以及相关的氧气消耗。蓝藻水华的控制没有得到全面的理解，这增加了基于模型的预测波罗的海变暖的未来的不确定性。在这里，我们回顾我们目前的理解蓝藻水华动力学。我们总结了已发表的实地研究和实验室实验，并剖析了最先进的耦合海洋环流地球化学模型中根深蒂固的基本原则。
Abstract. The ecosystem of the Baltic Sea is endangered by eutrophication. This has triggered expensive international management efforts. Some of these efforts are impeded by natural processes such as nitrogen-fixing cyanobacteria blooms that add bioavailable nitrogen to the already over-fertilized system and thereby enhance primary production, export of organic matter to depth, and associated oxygen consumption. Controls of cyanobacteria blooms are not comprehensively understood, and this adds to the uncertainty of model-based projections into the warming future of the Baltic Sea. Here we review our current understanding of cyanobacteria bloom dynamics. We summarize published field studies and laboratory experiments and dissect the basic principles ingrained in state-of-the-art coupled ocean–circulation biogeochemical models.
