Caspian 40m 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 50m depth of the Caspian Sea. Sampling was performed at the end of summer, a time when the water column is stratified based on temperature. Briefly, 50L of water was collected from this depth and filtered serially through 20, 5 and 0.22 micron filters. this metagenomes deposited here was obtained by sequencing (Illumina HiSeq) of the 0.22 micron fraction.
