A synergy of observations: Filling the gaps in an ocean colour chlorophyll-a record

Daniel J. Ford February 20, 2026

Satellite ocean colour chlorophyll-a provides synoptic scale observations that highlight the turbulent and dynamic nature of the oceans (Credit: Daniel Ford generated from ESA OC-CCI data).

Chlorophyll-a (chl-a), as the dominant photosynthetic pigment within phytoplankton, provides an indication of the phytoplankton biomass and are essential for understanding global and regional changes in primary production in the oceans. Multiple ocean colour satellites have unlocked routine synoptical scale observations of chl-a which now extends from 1997 to the present day. Differing numbers of ...[Read More]

As climate change continues to reshape our oceans, science communication remains vital to the research and development of mitigation strategies. For scientists and engineers working on climate solutions, much of the conversation happens through technical papers, conference presentations, and policy memos. But invested communities outside these circles may have little access and limited time to con ...[Read More]
