Shotgun metagenomic dataset of microbial communities in the water column of the Flores Sea, Indonesia

The Flores Sea is a crucial component of the Indonesian Throughflow (ITF) pathway, which influences the transport of carbon, oxygen, and nutrients that support marine ecosystems. Here, we present the first dataset of microbial communities from the Flores Sea, Indonesia, generated using shotgun metagenomic sequencing of water column samples. Taxonomic analysis revealed that Proteobacteria (86%) was the most abundant phylum. In the dataset, the most abundant taxa identified through metagenomic analysis demonstrated Pseudoalteromonas lipolytica, Chromohalobacter salexigens, Marinobacter nauticus, Halopseudomonas aestusnigri, Pseudomonas mendocina, Flavobacterium beibuense, and Flavobacterium rakeshii, respectively. Functional annotation indicated that metabolism was major functional category in the microbial community. This metagenomic dataset provides valuable baseline information on microbial communities that may support future ocean monitoring and conservation strategies in the Flores Sea.
