Sea Surface Temperature Anomaly



The real-time sea surface temperature anomaly, updated daily, is the difference between the current temperature and the long-term temperature average. Negative temperature differences indicate that the ocean is cooler than average, while positive temperature difference indicate that the ocean is warmer than average. Tracking sea surface anomalies helps scientists quickly identify areas of warming and cooling, which can effect coral reef ecosystems, hurricane development, and the development of El Nino and La Nina.
