16S rRNA gene (from DNA) from samples collected on cruise Chikyu-331 in the Okinawa Trough, Japan from September to October 2010

<p>Next-generation sequencing data across a hydrothermal gradient; Okinawa Backarc Basin IODP 331 – subvent biosphere.&nbsp;The purpose of this dataset was to investigate taxonomic changes via the 16S rRNA gene from extractable DNA across 45 meters of recovered core. The temperature gradient in this section of the dynamic Iheya North Hydrothermal system was estimated to be ~3C/m. The interval transitions sharply from low-temperature marine mud to hydrothermally altered clay.</p>

沿热液梯度分布的新一代测序（next-generation sequencing）数据集，源自冲绳弧后盆地国际大洋发现计划（International Ocean Discovery Program, IODP）331航次——俯冲带下生物圈研究。本数据集旨在通过提取自45米长回收岩心的DNA中的16S rRNA基因，探究岩心中微生物类群的分类学组成变化。该活跃的伊平屋北热液系统的对应岩心段温度梯度约为3℃/米。该岩心段的沉积环境发生显著转变，由低温海相泥质沉积物过渡为热液蚀变黏土。
