Rainfall patterns in the Sahara during the 6,000-year "Green Sahara" period have been pinpointed by analyzing marine sediments, according to new research.
Past variations in the strength of the Earth's magnetic field are reflected by the production of isotopes in the atmosphere. Researchers from the CNRS, Aix Marseille Université and the French Alternative Energies and Atomic ...
Clues from prehistoric droughts and arid periods in California show that today's increasing greenhouse gas levels could lock the state into drought for centuries, according to a study led by UCLA professor Glen MacDonald.
A unique study by scientists at the National Oceanography Centre (NOC) will provide valuable new insights into the concentrations of microplastics in the open ocean from surface to the sea bed.
When NASA began seeking new scientists to join its Curiosity Mars rover team, Penn State geoscientist Christopher House knew his experience could be a valuable asset to the project.
Underwater sound linked to human activity could alter the behaviour of seabed creatures that play a vital role in marine ecosystems, according to new research from the University of Southampton.
Some of the world's tiniest organisms may have a large impact on climate change. Researchers from the U.S. Department of Energy's Argonne National Laboratory and the University of Tennessee found that microorganisms called ...
Previously undocumented in North American rivers, concentrations of microplastic particles in the St. Lawrence are as high as has been observed in the world's most contaminated marine sediments.
Researchers at the University of California, San Diego School of Medicine have discovered a widely distributed group of marine bacteria that produce compounds nearly identical to toxic man-made fire retardants.
Determining species diversity makes it possible to estimate the impact of human activity on marine ecosystems accurately. The environmental effects of salmon farming have been assessed, until now, by visually identifying ...
