Phytoplankton respond within hours to days to perturbations in environmental conditions. This makes them ideal indicators to study the first-level biological responses to climate variability and change.

The prevalence of one El Niño mode over another can have profound impacts on the marine ecosystem structure and functioning – affecting trophic interaction (fisheries) and carbon fluxes

The responses of phytoplankton to El Niño variability and the driving physical processes are characterised in the global oceans based on ocean-colour, SST, sea level and wind observations.
We observe regionally different patterns in the response of phytoplankton and physical processes to two extreme types of El Niño
