Variability and 20-year trends in satellite-derived surface chlorophyll concentrations in large marine ecosystems around South and Western Central America

This research paper analyzes 20-year trends in satellite-derived surface chlorophyll concentrations across four Large Marine Ecosystems (LMEs) around South and Western Central America, using combined data from SeaWiFS (1997–2006) and MODIS Aqua (2002–2017).

• The study identified significant increases in chlorophyll concentrations over the last approximately 20 years in large portions of the Patagonia (PLME) and Humboldt (HLME) Large Marine Ecosystems, specifically affecting 78.23% of the PLME and 43.03% of the HLME. These widespread changes may have significant implications for fish reproductive success and trophic relationships.
• In contrast to the widespread increases in the PLME and HLME, increasing trends in chlorophyll concentrations were detected only in relatively small regions of the South Brazil (SBLME) and Pacific Coastal Central America (PCACLME) ecosystems, covering 26.35% and 13.35% respectively.
