Groundwater Flow May Contribute to Submarine Permafrost Thaw
New, detailed surveys from the Beaufort Sea reveal a seafloor depression the size of a city block associated with permafrost thaw and likely influenced by the movement of groundwater below.
Uranium Detected in Latinx Communities’ Water Systems
The unsafe contaminant levels could not be attributed to differences in regional geology, water source, or community size. Researchers suggest they are due to a failure of regulatory policy.
A Sharper Look at the World’s Rivers and Catchments
Digital hydrographic maps have transformed global environmental studies and resource management. A major database update will provide even clearer and more complete views of Earth’s waterways.
U.S. Fires Quadrupled in Size, Tripled in Frequency in 20 Years
Changes including intensifying drought, expansion into burnable land, and an increase in human-caused ignitions have led to a shift in fire patterns.
Mapeando el pasado, presente y futuro de Teotihuacan
Un nuevo proyecto con tecnología lidar revela cómo la minería y la expansión urbana han puesto en riesgo a uno de los sitios del patrimonio cultural más icónicos de México.
Black Neighborhoods Will Bear Future Flood Burden
Climate change, shifting populations, and infrastructure development in risky areas compound future flood loss risk.
Fiber-Optic Cables Can Produce High-Resolution Underground Maps
Telecom fiber repurposed as distributed acoustic sensing arrays can image near-surface structure and potentially improve seismic hazard mapping in urban areas.
Mapping a River Beneath the Sea
A recent expedition mapped one of the world’s longest submarine channels, revealing previously undiscovered physical features and raising questions about its unusual origin and shape.
Mapping Teotihuacan’s Past, Present, and Future
A new lidar project reveals how mining and urban expansion have put one of Mexico’s most iconic cultural heritage sites at risk.
