Seasonal dynamics of bacterioplankton community structure at a coastal station in the western English Channel
International audience An annual study of the bacterioplankton community structure was carried out at Stn L4 (50° 15'N, 04° 13'W) in the western English Channel between August 2003 and July 2004. Bacterioplankton abundance and community structure were assessed using flow cytometry and fluo...
