Description 
Summary

Studies of phytoplankton in the Gulf of Riga have been carried since 1975. 1975-1992 Samples were collected from 0 m and 10 m depth with bathometers. Formaldehyde was used for sample fixations. Since 1993 acid Lugol's solution is used for sample fixations. 1993-1998 According to Manual for Marine Monitoring in COMBINE Programme of HELCOM samples were collected from 0, 2.5; 5; 7.5 and 10 metres with bathometer and mixed together in one sample. The results were presented for integrated (0-10 m) water column. Since 1998 the counting program recommended by Manual for Marine Monitoring in COMBINE Programme of HELCOM is used. 1999-2004 According to Manual for Marine Monitoring in COMBINE Programme of HELCOM samples were collected with hose (0-10 m). Since 1997 data were send to Finish Institute of Marine Research homepage 'Algaline' (http://www4.fimr.fi/project/algaline/algaline.htm).
