Wind-driven sand is understood to create ripples on a centimeter scale and dunes spanning tens of meters, but so-called megaripples of intermediate size have remained puzzling. A theory of aeolian ...

Massive megaripples, formed by the tsunami after the Chicxulub asteroid impact 66 million years ago, have been mapped deep beneath Louisiana using 3D seismic data.

Massive megaripples, formed by the tsunami after the Chicxulub asteroid impact 66 million years ago, have been mapped deep beneath Louisiana using 3D seismic data.

In 2021, a team led by Dr Gary Kinsland of the University of Louisiana at Lafayette found evidence that the impact and resulting tsunami left "megaripples" of sediment 16 meters (53 feet) high and ...

Conversely, megaripples in the deep sea took on varied shapes, likely as a result of interactions with faults and collapses, according to Live Science.

This new map of the megaripples can help predict the impact of future tsunamis, and to better understand the dinosaur extinction event, scientists say.

Scientists have created a new map of "mega ripples" on the seafloor caused by the Chicxulub asteroid impact that wiped out the dinosaurs, revealing further the events that led to the devastating mass ...

Paleo-megaripples – as seen in Mars’ Terra Sirenum by the High-Resolution Imaging Science Experiment – have consistent crest wavelengths, numerous fractures and craters, and can be partially covered ...

Fossils Of Mars’ Climate Show A Different World 2 Billion Years Ago Some of the regions of the Red Planet keep a record of what the planet was like in the past.
