The Operational Land Imager (OLI) on the Landsat 8 satellite captured this image of an algal bloom on Lake Villarrica in Chile on May 2, 2023. Ground-based observations and analysis of additional satellite images suggest that cyanobacteria make up the light blue-green swirls in the natural-color image.
Adding to the grim list of record ice losses, record air temperatures and record droughts, which have all hit the headlines recently, the temperature of the surface waters of our oceans is also at an all-time high.

Using two decades of NASA satellite measurements stored in the cloud, scientists recently assessed the vulnerability of Belize’s renowned coral reefs to bleaching and collapse.
The international Surface Water and Ocean Topography (SWOT) mission–led by NASA and the French space agency Centre National d’Études Spatiales (CNES)–sent back some of its first glimpses of water on the planet’s surface, showing ocean currents like the Gulf Stream in unprecedented detail.
An astronaut aboard the International Space Station (ISS) photographed the island of Hawai’i and its snowcapped volcanoes Mauna Loa and Mauna Kea.
