marine surface seawater Metagenome. seawater metagenome

Oligotrophic region is widespread in the global ocean. The South China Sea (SCS), an ocean-dominated marginal sea has the typical features of tropical oligotrophic ocean. In this study, metagenomic sequencing and analysis was carried out on a seawater sample collected on 0.2 μm polycarbonate filter from deep chlorophyll maximum at the South East Asia Time-Series (SEATS) station in the SCS during the summer cruise in 2012. Our metagenomic data could be a supplement to the global ocean sampling (GOS) metagenomic database which totally lacks samples from the SCS. This study could deepen our understanding of microbial roles in biogeochemical cycle in an oligotrophic ocean-dominated marginal sea.
