Barents Sea Tied to Low Arctic Sea Ice
At the top of the planet, the cap of sea ice across Arctic waters grows and shrinks with the seasons, usually reaching its annual maximum extent in March. In 2026, this peak occurred on March 15, when the extent reached 14.29 million square kilometers, matching the lowest maximum observed since satellite monitoring began in 1979. One of the key areas contributing…

Réunion Island Lava Reaches the Sea
Located 700 kilometers (440 miles) east of Madagascar, Réunion Island is the product of a long-lived mantle hotspot on the floor of the Indian Ocean. The island first emerged above the ocean’s surface about 2 million years ago. It remains active today, with frequent eruptions from Piton de la Fournaise, a shield volcano on the island’s eastern side. Since the 17th century, the…

Seeing Blue During Schirmacher’s Summer Melt Season
Summer is a busy season at Schirmacher Oasis, a rocky, ice-free plateau in Queen Maud Land, East Antarctica. Located near the grounding line of Nivlisen Ice Shelf and about 100 kilometers (60 miles) from the open waters of the Lazarev Sea, the “oasis” of land amid an otherwise continuous expanse of ice is home to dozens of small ice-covered freshwater lakes and two research stations. It’s…

Landsat Reveals Reservoir Changes and Bathymetry
Communities worldwide rely on reservoirs for drinking water, hydroelectric power, irrigation, and more. These critical freshwater resources are affected by seasonal and long-term changes; water levels in reservoirs can dip during hot summer months or due to prolonged drought, or can flood after a particularly strong storm. Despite their importance, there are key gaps in our knowledge of reservoir structure…
