关于红海南部大规模生物过程的知识相对有限，这主要是因为现场和卫星获取的叶绿素a(Chl-a)数据集很少。在夏季，红海南部恶劣的大气条件(雾霾和云层)长期以来严重限制了卫星海洋颜色观测的恢复。最近，欧洲航天局(欧空局)开发的一种新的合并海洋颜色产品--海洋颜色气候变化倡议(OC-CCI)--大大改善了南部红海Chl-a的覆盖面，使人们能够发现意想不到的夏季水华。在这里，我们首次详细描述了它们的时空分布，并报告了它们的调节机制。在夏季，季风驱动的风向逆转改变了曼德布海峡的环流动态，导致来自印度洋的更冷、更新鲜、更富营养的水从地下涌入。利用卫星观测、模型模拟输出和现场数据集，我们追踪了这次入侵进入盆地沿岸广泛的浅水区和珊瑚礁复合体的路径。我们还提供了统计证据，表明次表层入侵在红海南部浮游植物水华的发展中起着关键作用。
Knowledge on large-scale biological processes in the southern Red Sea is relatively limited, primarily due to the scarce in situ, and satellite-derived chlorophyll-a (Chl-a) datasets. During summer, adverse atmospheric conditions in the southern Red Sea (haze and clouds) have long severely limited the retrieval of satellite ocean colour observations. Recently, a new merged ocean colour product developed by the European Space Agency (ESA)—the Ocean Color Climate Change Initiative (OC-CCI)—has substantially improved the southern Red Sea coverage of Chl-a, allowing the discovery of unexpected intense summer blooms. Here we provide the first detailed description of their spatiotemporal distribution and report the mechanisms regulating them. During summer, the monsoon-driven wind reversal modifies the circulation dynamics at the Bab-el-Mandeb strait, leading to a subsurface influx of colder, fresher, nutrient-rich water from the Indian Ocean. Using satellite observations, model simulation outputs, and in situ datasets, we track the pathway of this intrusion into the extensive shallow areas and coral reef complexes along the basin’s shores. We also provide statistical evidence that the subsurface intrusion plays a key role in the development of the southern Red Sea phytoplankton blooms.
