A third of rivers in US found to be changing from blue to green and yellow

Credit: Unsplash/CC0 Public Domain A team of researchers with members from the University of North Carolina at Chapel Hill and Colorado State University reports that approximately a third of the rivers in the U.S. have changed color over the past 34 years. In their paper published in the journal Geophysical Research Letters, the group describes […]

US rivers are changing from blue to yellow and green, satellite images show

  A third of U.S. rivers have significantly changed color over the last 36 years, turning from blue to  yellow and green, striking new images reveal. Researchers analyzed 235,000 satellite images — taken over a 34-year period between 1984 and 2018 — from NASA and the U.S. Geological Survey (USGS) Landsat program. The changing hues […]

Community conservation reserves protect fish diversity in tropical rivers — ScienceDaily

Prohibiting fishing in conservation reserves is a common strategy for protecting ocean ecosystems and enhancing fisheries management. However, such dedicated reserves are rare in freshwater ecosystems, where conservation efforts generally piggyback on the protection of terrestrial habitats and species. Now, a collaboration between researchers from Cornell University and the University of Wisconsin-Madison has found that […]

Shift in atmospheric rivers could affect Antarctic sea ice, glaciers — ScienceDaily

Weather systems responsible for transporting moisture from the tropics to temperate regions in the Southern Hemisphere have been gradually shifting toward the South Pole for the past 40 years, a trend which could lead to increased rates of ice melt in Antarctica, according to new research. Atmospheric rivers are long, narrow jets of air that […]

Rivers melt Arctic ice, warming air and ocean — ScienceDaily

A new study shows that increased heat from Arctic rivers is melting sea ice in the Arctic Ocean and warming the atmosphere. The study published this week in Science Advances was led by the Japan Agency for Marine-Earth Science and Technology, with contributing authors in the United States, United Arab Emirates, Finland and Canada. According […]

Urbanization, Agriculture, and Mining Threaten Brazilian Rivers

Researchers in Brazil and the United States have found that agriculture, urbanization, and mining are great threats to water quality in Brazilian rivers. These land uses are important sources of pollution but often remain unaccounted for in analyses of water quality. Published in September in the Journal of Environmental Management, the study is […]
