Gradients of bacteria in the oceanic water column reveal finely-resolved vertical distributions

v1v2 Illumina amplicon sequence data of the 16S rRNA gene. we implemented resolved approaches for studying evolutionary relationships and bacterial vertical distributions in the ocean. Replicated sampling was performed at multiple depths, at different sites in and near Monterey Bay off coastal USA, ranging from the surface waters to the seafloor over seasons and years, which facilitated identification of robust patterns in bacterial diversity profiles.

16S核糖体RNA（16S rRNA）基因v1v2区的Illumina扩增子测序数据。本研究采用经验证的分析方法，用于探究海洋中细菌的演化关系与垂直分布格局。研究团队于美国沿海蒙特雷湾（Monterey Bay）及其邻近海域的多个位点开展多深度重复采样，采样覆盖从表层海水至海底的全部水层，且历时数年、跨多个季节进行，这为精准识别细菌多样性特征的稳健模式提供了有力支撑。
