Researchers have found evidence of a sandstorm on Mars that occurred about 3.6 billion years ago.

Drilling Down to Open Up New Understanding of Earth’s Continents
Scientists have drilled into Earth’s crust for decades to understand natural hazards, past climates, energy resources, and more. They’ve only scratched the surface of what we can learn.
Sediments Offer an Extended History of Fast Ice
Scientists used sediments to create a millennia-long archive of Antarctic fast ice. Along the way, they discovered that the freezing and thawing of this enigmatic ice appear to be linked to solar cycles.
The AMOC of the Ice Age Was Warmer Than Once Thought
An analysis of sediment cores indicates that North Atlantic waters were relatively warm and continued to circulate even under major climate stress during the Last Glacial Maximum.
How the Rise of a Salty Blob Led to the Fall of the Last Ice Age
Scientists have long suspected that high salinity levels in the deep ocean were responsible for keeping carbon dioxide locked away during the last ice age. New research finds the strongest evidence yet.
New Eyes on One of the Planet’s Largest Submarine Landslides
Researchers have mapped the ancient Stad Slide off the coast of Norway to better understand what triggered it, and the hunt is on for the tsunami it might have unleashed.
Glass Sand Grows Healthy Mangroves
In places with lots of glass waste, sand made from recycled material could be another tool in the coastal restoration toolbox.
Glacier Runoff Becomes Less Nutritious as Glaciers Retreat
Sediment from retreating, land-terminating glaciers contains proportionally fewer micronutrients such as iron and manganese, reducing the glaciers’ value to microorganisms at the base of the food web.
Sediments Hint at Large Ancient Martian Moon
Regular, alternating layers in Gale Crater may have been deposited as the result of tides raised by a moon at least 18 times the mass of Phobos, a study says.
When Cascadia Gives Way, the San Andreas Sometimes Follows
Roughly half of the earthquakes that occurred along the southern Cascadia subduction zone over the past 3,000 years were temporally associated with earthquakes along the northern San Andreas fault.
