When using pyrite to understand Earth’s ocean and atmosphere: Think local, not global
The ocean floor is vast and varied, making up more than 70% of the Earth’s surface. Scientists have long used information from sediments at the bottom of the ocean — layers of rock and microbial muck — to reconstruct the…
Gulf Stream System at its weakest in over a millennium
Never before in over 1000 years the Atlantic Meridional Overturning Circulation (AMOC), also known as Gulf Stream System, has been as weak as in the last decades. This is the result of a new study by scientists from Ireland, Britain…
New model describes wave behavior in straits, predicts killer waves
A Skoltech researcher has developed a theoretical model of wave formation in straits and channels that accounts for nonlinear effects in the presence of a coastline. This research can improve wave prediction, making maritime travel safer and protecting coastline infrastructure.…
Sea turtle: Sentinels and victims of plastic pollution in the Adriatic Sea
Sea turtles are witnesses and victims of the high level of plastic pollution of the Adriatic Sea. A group of researchers at the University of Bologna analysed 45 turtles hospitalised at Fondazione Cetacea in Riccione and found plastic debris in…
