Monthly samplings carried out in 2016–2019 and satellite color images from 2002 to 2019 have been combined to determine the onset and causative species of the ecosystem disruptive algal bloom (EDAB) that affects the Mar Menor coastal lagoon (Western Mediterranean Sea) since 2015. Substantial changes in satellite spectral reflectance attributable to increasing abundance of Synechococcus were registered in 2014. Furthermore, cell abundances of this species in 2016 were the largest ever obtained in the lagoon (6 10⁶ cells mL⁻¹), with values similar to those reported for other Mediterranean hypertrophic estuaries and coastal lagoons. These results suggest that the early changes leading to the EDAB started in 2014 and that Synechococcus played a relevant role in its development. Moreover, diatom and dinoflagellate abundances changed substantially in 2016–2019, ranging from 10² to more than 10⁴ cells mL⁻¹. Some of these changes were linked to flood, suggesting that EDAB has modified substantially the homeostatic capacity of the lagoon.

2016年至2019年进行的每月采样以及2002年至2019年的卫星彩色图像已被结合起来，用于确定自2015年以来影响Mar Menor沿海泻湖（西地中海）的生态系统破坏性藻华（EDAB）的起因和致病物种。在卫星光谱反射率归因于增加丰度显着变化聚球蓝细菌被登记在2014年此外，这种在2016年的细胞丰度分别在泻湖曾经获得的最大（6个10 ⁶细胞毫升^-1）中，用类似的报告值其他地中海肥厚的河口和沿海泻湖。这些结果表明，导致EDAB的早期变化始于2014年，而Synechococcus在其发展中发挥了重要作用。此外，硅藻和鞭毛藻的丰度在2016-2019年发生了显着变化，范围从10 ^2个细胞mL ^-1到超过10 ^4个细胞mL ^-1。其中一些变化与洪水有关，这表明EDAB大大改变了泻湖的体内平衡能力。
