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>

冲绳弧后盆地国际大洋发现计划（International Ocean Discovery Program，IODP）331航次俯冲下生物圈的热液梯度下一代测序（Next-generation sequencing）数据集。本数据集旨在通过提取自45米回收岩心的可提取DNA中的16S rRNA基因（16S rRNA gene），探究微生物类群的群落分类学变化。动态伊平屋北热液系统该区域的温度梯度约为3℃/米，该岩心段沉积物从低温海相泥快速过渡至经热液蚀变的黏土。
