How ice-age sea-level falls may have turned seafloor volcanoes into ocean fertilizer
A study published in Nature Geoscience suggests that iron released from deep-sea hydrothermal vents during ice-age transitions may have fertilized plankton. This process could have increased ocean carbon storage, creating a feedback loop between volcanic activity and climate.
Why it matters
Understanding these historical climate feedback loops provides critical insights into how the ocean regulates atmospheric carbon dioxide levels.
A Nature Geoscience study led by Boston College suggests that increased iron released from deep-sea hydrothermal vents during ice-age transitions could have reached sunlit waters and fueled plankton growth, potentially increasing ocean carbon storage
