Summary:

- Deep ocean earthquakes near Antarctica can trigger massive blooms of phytoplankton, tiny marine plants that form the base of the ocean's food chain.
- The seismic activity caused by these earthquakes disturbs the ocean floor, releasing nutrients that fuel the growth of phytoplankton.
- These phytoplankton blooms are important for the overall health and productivity of the Antarctic ecosystem, providing food for larger marine life like whales, seals, and fish.
