Mars Might Have Been Covered in Lakes in the Ancient Past

Ever since robotic explorers began visiting the Red Planet during the 1960s and 70s, scientists have puzzled over Mars’ surface features. These included flow channels, valleys, lakebeds, and deltas that appear to have formed in the presence of water. Since then, dozens of missions have been sent to Mars to explore its atmosphere, surface, and … Read more

Future-proofing the Great Lakes region through climate research

Credit: Unsplash/CC0 Public Domain Researchers are studying the way warming water temperatures will impact the Great Lakes region. Their work shows that small differences in lake surface temperatures can have a big impact on summer climate and can fuel extreme weather—crucial information. The Great Lakes have a profound impact on the country’s identity, economy and … Read more

Conserving critical habitat in face of climate change in Midwestern lakes by managing watershed land use

Credit: CC0 Public Domain Lakes across the Midwest are losing cold, oxygenated habitat as a result of climate change and nutrient pollution. This loss of critical habitat has negative consequences for water quality, fish, and the production of greenhouse gases. While data show that effectively manage watershed land use at a local scale can protect … Read more

Antarctica’s only active volcano shows how CO2 allows volcanoes to form persistent lava lakes at the surface

Left: 3D visualization from the magnetotelluric scan of Erebus interior (red is most conductive and magma rich); Right: schematic depiction of magmatic processes. Upward flow from a deep crustal valve zone undergoes episodic breakthrough of CO2 and entrained magma. Spatially continuous upflow of CO2-dominated magma is in contrast to depth-limited magma zones of H2O arc … Read more
