PHYTOPLANKTON BIOMASS AND BIODIVERSITY CLIMATE CHANGE INITIATIVE (PHYTO-CCI)
Phytoplankton play a central role in the Earth System. Through the production of organic carbon, phytoplankton drive major processes in the ocean carbon cycle and form the basis of almost all life in the ocean. Phytoplankton have high biodiversity and this is complemented by their functional diversity, which recognises that different types of phytoplankton play varied roles in marine ecosystems and in biogeochemical cycles of the ocean. With many of the satellite-retrieval algorithms related to phytoplankton maturing over time, we are now in a position to produce such phytoplankton products to the ensemble of the European Space Agency Climate Change Initiative. Here we present the first results of the PHYTO-CCI project that aims to develop satellite-based data products for two Essential Climate Variables (ECVs) identified by the Global Climate Observing System (GCOS): phytoplankton carbon biomass and pigment diversity. Results from a user consultation showed that Earth Observation scientists and ecosystem modellers have similar requirements as identified by GCOS, but prefer higher spatial and temporal resolution for a variety of applications, including coastal marine ecosystem studies. The intercomparison of satellite retrieval algorithms for phytoplankton carbon showed similar performance of several algorithms and a blended algorithm approach was investigated, and for phytoplankton pigments, a single algorithm showed highest performance. A first dataset of ECV products with associated uncertainties was produced for 1998-2025 to further assess the value of the new ocean biosphere ECVs in their application in climate research and their relevance for supporting marine ecosystem services.
