Monitoring Phytoplankon in Brest Bay (North Finistère)

This monitoring programme, relating to community structure, aims to highlight changes over time at various time scales : seasonal evolutions (such as spring blooms), inter-annual changes (such as the apparition or disappearance of species) or changes over decades (such as changes caused by natural and man-made factors). In order to complete this task, weekly taxonomic counts are made of micro-phytoplankton and some nano-phytoplankton. As far as possible they are identified specifically.
