What's Current in

Ocean and Beaches

On the water and on the sand, our research explores ocean health and evolution so we can better understand how to protect and preserve the largest area of Earth.

Sea surface temperatures in the tropical Pacific Ocean were already far higher than average by the first week of June 2026 due to El Niño.

El Niño has become more intense over last 40 years than the previous 1,000 years
