Spring of Kerguelen

The Kerguelen Spring is a seasonal phenomenon where warm ocean waters rise from below the surface around the Kerguelen Islands in the Southern Indian Ocean. This upwelling brings nutrient-rich water to the surface, fostering the growth of phytoplankton—tiny plants that form the foundation of the marine food chain. It typically occurs during austral spring (September to November) and supports abundant marine life, including fish, seals, and seabirds. This process is vital for maintaining the health of the ecosystem, influencing local biodiversity and global climate patterns by helping regulate carbon dioxide levels in the atmosphere.
