Regionally-differentiated El Niño impacts

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

Two types of El Niño

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
