Satellite image of the Great Lakes captured on February 24, 2024, by the Visible Infrared Imaging Radiometer Suite sensor aboard the Suomi NPP satellite.The effects of a warm winter in the upper Midwest are evident in the lack of lake ice.Ice coverage on the Great Lakes typically reaches its annual peak in late February or early March. But at that time in 2024, the lakes were conspicuously free of ice. Owing to warmer winter weather and above-average surface water temperatures, ice cover stood at historic lows.Since…

New research conducted by the University of Washington and published in Communications Earth & Environment highlights a shallow “soda lake” in western Canada as a potential match for these conditions. The findings…

This panoramic view shows Last Chance Lake in western Canada in November 2021, when the lake has shrunk into many smaller pools and ice has formed on top of each pool. Two University of Washington researchers stand on the lake's icy surface.

Lake level changes in China during 2002–2023 (a) >1000 km2; (b) 500–1000 km2; (c) 100–500 km2; (d) 50–100 km2; (e) 10–50 km2. Credit: Big Earth Data (2024). DOI: 10.1080/20964471.2023.2295632 A recent study published in Big Earth Data has shown how scientists from the Aerospace Information Research Institute (AIR) of the Chinese Academy of Sciences (CAS) harnessed satellite altimetry to track changes in the water level of…

Credit: Ethan D. Kyzivat When it comes to greenhouse gases, methane is one the biggest contributors. Not only is it massively abundant—it's about 25 times more potent than carbon dioxide at trapping heat in the atmosphere. That makes tracking methane emissions critically important, and nowhere more so than in the Arctic, which is now the fastest…

The digital age has ushered in an unprecedented era of data proliferation. Organizations are grappling with complex datasets that extend beyond traditional databases, straining resources and presenting challenges in data management. In the face of this rising tide of data, the need for robust, scalable, and flexible data storage solutions has never been more pressing. Enter Data Lakes—a solution offering an architecture that unifies your data ecosystem, serving as the cornerstone of modern data management strategies. The…

The Copernicus Sentinel-2 mission captures the vivid colors of Lake Natron and Lake Magadi in East Africa, highlighting their unique ecological and geological features. The satellite’s advanced imaging techniques reveal the dynamic environments of these lakes and contribute to environmental monitoring as part of the Copernicus program.

Wildlife officials across the Great Lakes are looking for spies to take on an almost impossible mission: stop the spread of invasive carp.Over the last five years, agencies have employed a new seek-and-destroy strategy that uses turncoat carp to lead them to the fish's hotspot hideouts.Agency workers turn carp into double agents by capturing them, implanting transmitters and tossing them back. Floating receivers send real-time notifications when a tagged carp swims past. Carp are large fish with an even larger appetite.…

Two years later, I began a large-scale survey of mountain lakes and amphibian populations: from east to west, I covered more than 100 mountain lakes located in the eastern Pyrenees to the Béarn region (Pyrénées-Atlantiques). For our various projects, we…
