title: MedWinter-JAN2015-20m metagenome sample from Mediterranean Sea
design: The deep chlorophyll maximum (DCM) is a zone of maximal photosynthetic activity, generally located toward the base of the photic zone in lakes and oceans. In the Mediterranean and other temperate waters, the DCM is a seasonal phenomenon. MedWinter-JAN2015-20m was obtained from the 5-0.22 microns fraction when the water column is mixed and the DCM disappears.
