The atmosphere is the least understood biome on Earth despite its critical role as a microbial transport medium. The influence of surface cover on composition of airborne microbial communities above marine systems is unclear. Here we report evidence for a dynamic microbial presence at the ocean-atmosphere interface of a major marine ecosystem, the Great Barrier Reef, and identify that recent air mass trajectory over an oceanic or continental surface associated with observed shifts in airborne bacterial and fungal diversity. Relative abundance of shared taxa between air and coral microbiomes varied between 2.2 and 8.8% and included those identified as part of the core coral microbiome. We propose that this variable source of atmospheric inputs may in part contribute to the diverse and transient nature of the coral microbiome.

气团来源决定了大堡礁海洋生态系统海气界面的空气微生物多样性。

大气是地球上最不为人知的生物群落，尽管它作为微生物运输介质发挥着关键作用。地表覆盖对海洋系统上方空气传播微生物群落组成的影响尚不清楚。在这里，我们报告了在主要海洋生态系统大堡礁的海气界面存在动态微生物的证据，并确定了最近在海洋或大陆表面上空的气团轨迹与观察到的空气中细菌和真菌多样性的变化有关。空气和珊瑚微生物组之间共享分类群的相对丰度在 2.2% 和 8.8% 之间变化，包括那些被确定为核心珊瑚微生物组的一部分。我们认为，大气输入的这种可变来源可能部分促成了珊瑚微生物群落的多样性和短暂性。
