Researchers from the Faculty of Sciences University of Lisbon collaborated on an international study that, for the first time, characterized the sounds emitted by the flying gurnard.

This study highlights an underwater world of sounds that can provide deeper insights into how marine ecosystems work.

A new study out of York University has found that the amount of atmospheric trifluoroacetic acid (TFA), the tiniest forever chemical, significantly declined in Toronto during COVID in 2020, which researchers say is good news for the world’s ability to mitigate it in the future. “When we turned off the tap, so to speak, and we all went home and stopped normal activities, we saw a really quick response, a dramatic reduction of TFA. But the real surprise is that the results point to TFA being formed from short-lived chemical precursors emitted into the atmosphere,” says York University atmospheric chemist Professor Cora Young, senior author of the paper published today.

The King’s Trough Complex is a several-hundred-kilometre-long, canyon-like system of trenches on the North Atlantic seafloor. Its formation was long thought to be the result of simple stretching of the oceanic crust. An international research team led by the GEOMAR Helmholtz Centre for Ocean Research Kiel has now shown that the so-called “Grand Canyon of the Atlantic” was formed around 37 to 24 million years ago through the interplay of a temporarily existing plate boundary and an early branch of the Azores mantle plume. Their findings have been published in the AGU journal Geochemistry, Geophysics, Geosystems (G-Cubed).
