Phytoplankton diversity, abundance and biomass
  • Smaller Small Medium Big Bigger
  • Default Helvetica Segoe Georgia Times

Rationale: Phytoplankton is the first link of all trophic chains in marine ecosystems and only the primary producer in the open water. Its diversity, abundance, biomass and production will be important for how much energy is available for other trophic levels

Theme: Biotic

Component: Phytoplankton

Type of indicator: E, state of the ecosystem

Priority of indicator: e, essential

• Species composition (CBMP, Arctos network/NPI, IMR, PINRO)
• Species abundance (CBMP, Arctos network/NPI, IMR, PINRO)
• Group abundance Dinoflagellates, Diatoms and Coccolithophorids (CBMP, Arctos network/NPI, IMR, PINRO)
• CDOM, satellite (NERSC)
• PIC, satellites' (NERSC) and benthic samples
• Diversity indices (CBMP, Arctos network/NPI, IMR, PINRO)
• Start, duration and intensity of the spring bloom (NERSC)
• Start, duration and intensity of the late summer bloom (NERSC)
• Chlorophyll (NPI, MMBI, PINRO)
• Total biomass (IMR, PINRO)
• Net primary productivity (NERSC)
