Global Ocean Acidification Observing Network

The Global Ocean Acidification Observing Network (GOA-ON) is an international system that monitors changes in the ocean's chemistry, specifically its acidity levels. As CO₂ from the atmosphere dissolves into seawater, it makes the ocean more acidic, which can harm marine life like corals and shellfish. GOA-ON collects data from oceans worldwide to understand these changes over time. This information helps scientists and policymakers make informed decisions to protect ocean health, ensure sustainable fisheries, and address climate change impacts.
