The National Estuarine Research Reserve System is a U.S. network of protected coastal sites used for long-term science and monitoring, alongside education and stewardship. Each reserve pairs NOAA with a state or territorial partner, sometimes through a local institution. Together, the sites let researchers compare estuaries across regions while local teams apply the findings to…

Ecoforecasting uses environmental observations and models to predict changes in living systems before they affect people or ecosystems. A forecast might estimate where a harmful algal bloom will move or how large a seasonal low-oxygen zone could become. Other products track when heat stress may threaten coral reefs. Their purpose is practical: give communities time…
Ocean currents are measured in several ways. Some instruments follow water or listen for moving particles, while others scan the sea surface or infer motion from satellites. No single tool captures the whole ocean. Researchers combine ship and anchored-sensor records with drifting floats. Coastal radar and spacecraft extend the view from the shoreline to the…
Ocean acidification is the long-term decline in seawater pH caused mainly by the ocean absorbing carbon dioxide from the atmosphere. The ocean remains alkaline, yet its chemistry is moving toward the acidic end of the pH scale. That shift changes the forms of carbon dissolved in seawater and reduces the carbonate ions many marine organisms…
