Caspian 15m metagenome
aquatic metagenome
The Caspian Sea is the world's largest enclosed body of water. The northern part of the Caspian sea is largely a freshwater habitat. Salinity increases gradually towards the middle part, and the southernmost part is a stable brackish ecosystem with 1.1% salinty (ca. one third of the open ocean). This biosample contains metagenomic data from 15m depth of the Caspian. Briefly, 50L of water was collected from this depth and filtered serially through 20, 5 and 0.22 micron filters. This metagenome deposited here was obtained by sequencing (Illumina HiSeq) of the 0.22 micron fraction.
