18S V1V2 amplicon sequencing of SOMLIT-Astan time-series (2009-2012) DNA samples.

The SOMLIT-Astan sampling station (http://marineregions.org/mrgid/5372 ) is located in the western English Channel, 3.5 km off Roscoff (Brittany, France) (60 m depth, 48°46'18” N–3°58'6” W). Plankton samples were collected bi-monthly during high neap tide at surface (1 m depth) using a 5L Niskin bottle. For more details about the sampling see: https://doi.org/10.1111/mec.16539. Physico-chemical measurements can be found here: https://doi.org/10.17882/96634 .
