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

The study analyzed chlorophyll concentrations from 1997 to 2017 using SeaWiFS and MODIS Aqua data across four Large Marine Ecosystems (LMEs). It found significant increases in chlorophyll concentrations in large portions of the Patagonia (PLME) and Humboldt (HLME) ecosystems, while increases in the South Brazil (SBLME) and Pacific Coastal Central America (PCACLME) ecosystems were limited to smaller regions.

• Over the last approximately 20 years, significant increases in chlorophyll concentrations were observed across large areas of the Patagonia (PLME) and Humboldt (HLME) Large Marine Ecosystems, specifically affecting 78.23% of the PLME and 43.03% of the HLME. These changes may have substantial 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 subtropical South Brazil (SBLME) and tropical Pacific Coastal Central America (PCACLME) ecosystems, covering 26.35% and 13.35% respectively.
