Metagenomes of Callogorgia delta and surrounding sediment near natural active seepage 2015-2016

As part of a study to investigate the effect of natural seepage on deep-sea corals, the metagenomes of the octocoral, Callogorgia delta, and the surrounding sediment were sequenced. At sites within lease blocks MC751 and MC885, Callogorgia delta colonies can be found growing near visual signs of active seepage. Colonies were collected on 2015-05-02, 2016-10-01, 2016-09-29, 2017-06-06, and 2017-06-18 growing near or far from signs of seepage. Sediment samples were collected near corals with push cores. The metagenomes were sequenced to investigate the effects of natural seepage on the composition of the microbial communities associated with corals and sediment and to determine any changes in metabolic capabilities in these microbial communities.

本研究旨在探究自然渗漏对深海珊瑚的影响，对八放珊瑚（octocoral）德尔塔柳珊瑚（Callogorgia delta）及其周边沉积物的宏基因组（metagenome）开展了测序工作。
在MC751与MC885租赁区块内的采样位点，可发现德尔塔柳珊瑚群落生长于带有活跃渗漏视觉迹象的区域附近。
研究团队分别于2015年5月2日、2016年10月1日、2016年9月29日、2017年6月6日及2017年6月18日，采集了生长在渗漏迹象附近或远离渗漏迹象的德尔塔柳珊瑚群落样本。
采用活塞式采芯器（push core）在珊瑚周边采集了沉积物样本。
本次宏基因组测序旨在探究自然渗漏对珊瑚及沉积物相关微生物群落（microbial community）组成的影响，并明确此类微生物群落的代谢功能变化。
