Climate change is associated with higher phytoplankton biomass and longer blooms in the West Antarctic Peninsula

A. Ferreira, C. R. B. Mendes, et al.

Discover how 25 years of satellite data reveal significant changes in phytoplankton biomass and bloom phenology in the West Antarctic Peninsula, linked to climate change. This research by Afonso Ferreira, Carlos R. B. Mendes, Raul R. Costa, Vanda Brotas, Virginia M. Tavano, Catarina V. Guerreiro, Eduardo R. Secchi, and Ana C. Brito uncovers potential implications for global carbon sequestration and Antarctic food webs.

Abstract
This study uses 25 years of satellite data (1998–2022) to show that phytoplankton biomass and bloom phenology in the West Antarctic Peninsula are significantly changing due to anthropogenic climate change. Enhanced phytoplankton biomass, particularly in early austral autumn, results in longer blooms. Sea ice decline and intensification of the Southern Annular Mode (SAM) since 2010 are identified as key drivers. These ecological changes have potential far-reaching consequences for global carbon sequestration and Antarctic food webs.
