Abstract

Phytoplankton monitoring in the Baltic Sea is to a large extent harmonised through the HELCOM COMBINE protocol. This ensures that the methods of sampling and analysis are quite similar and that data should be relatively comparable. There are differences in the spatial and temporal coverage of samples taken within the different monitoring programs. Moreover, within the national monitoring programs there can be large variations in the number samples taken at different stations, between years and during the year. Most monitoring stations are sampled more frequently during summer. Although the chlorophyll a and species-specific phytoplankton biomass has been measured routinely and by standard methods since the early 1970s, most national monitoring programs have had a reasonable monitoring effort after about 1990 only. New methods for collecting data, such as ships-of-opportunity and remote sensing, provide additional information to the traditional shipboard sampling and other new emerging technologies may provide alternative means for monitoring phytoplankton.
