Over two decades along a productive Pacific coastline, declining ocean pH is linked to strong concurrent declines in dissolved Si:N and water-column chlorophyll.
- Why it matters: Ocean acidification may reduce dissolved silicon availability for diatoms, threatening a major source of ocean primary productivity and downstream coastal food webs.
- What they did: Using long-term monitoring data from the Pacific coastline, the study tested whether falling pH coincided with reduced Si:N and chlorophyll, including controls for potential Si transport vectors.
- The result: The observed Si:N and chlorophyll declines support the ocean acidification silicon loss hypothesis, suggesting this process is already ongoing in some productive ocean regions.
