The Impact of Large-Scale Climatological Events on Plankton Populations

Large climatological events like El Niño, La Niña, and the North Atlantic Oscillation (NAO), etc. significantly impact plankton populations, which are crucial to marine ecosystems and global biogeochemical cycles. El Niño reduces nutrient upwelling in the Pacific, decreasing phytoplankton biomass and disrupting the food web, while La Niña enhances upwelling, boosting phytoplankton and zooplankton populations. The NAO affects nutrient mixing and light availability, influencing plankton productivity in the North Atlantic. Understanding these impacts is essential for predicting and managing the effects of climate variability on marine ecosystems.
