Deep-sea earthquakes fuel huge plankton blooms in Antarctica: Hydrothermal vents spurred by seismic activity feed vital nutrients to Antarctic microbes.

The article focuses on new research indicating that earthquakes can enhance nutrient supply from hydrothermal vents in the Southern Ocean, which in turn supports massive phytoplankton blooms. These blooms, crucial for the marine food web and global carbon dioxide regulation, are linked to seismic activity that causes vents to release essential nutrients like iron more rapidly than previously understood. The study suggests that the relationship between deep-sea earthquakes and surface phytoplankton productivity may require a reevaluation of existing climate models, as the dynamics of nutrient transport could significantly impact carbon cycling in the region. Future research aims to explore these processes further, particularly in other volcanically active ocean ridges. [Extracted from the article]
