Prokaryotic diversity in the Southern Ocean (Kerguelen Region). marine metagenome

The present study was carried out as part of the project MOBYDICK (Marine Ecosystem Biodiversity and Dynamics of Carbon around Kerguelen: an integrated view) that aimed to provide a detailed picture of the diversity and role in the carbon cycling of biological communities of end-to-end food webs in contrasting nutrient regimes in the Southern Ocean. The main objective of the present study was to investigate the composition of the total (DNA) and potentially active (RNA) free-living and particle-attached prokaryotic communities in the upper 300m water column at 4 sites characterized by contrasting seasonal productivity regimes.

本研究作为莫比迪克（MOBYDICK）项目的组成部分开展，该项目全称为"凯尔盖朗海域海洋生态系统生物多样性与碳循环动力学：整合视角"，旨在全面解析南大洋不同营养盐环境下完整食物链食物网的生物群落多样性及其在碳循环中所扮演的角色。本研究的核心目标为，对4个具有差异化季节性生产力特征的采样站点的上层300米水层中，总（DNA）与潜在活性（RNA）的自由生活及颗粒附着原核生物群落的组成展开调查分析。
