Sediments Offer an Extended History of Fast Ice

by Taylor Mitchell Brown 12 February 202612 February 2026

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

by Grace van Deelen 10 February 202610 February 2026

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.

Tsunamis from the Sky

by Ivica Vilibić, Petra Zemunik Selak and Jadranka Šepić 3 February 20263 February 2026

Not all tsunamis come from the seafloor, some are triggered by the atmosphere, driven by fast-moving storms and pressure waves, and can strike coasts with little warning.

A Mid-Ocean Ridge in the Norwegian Sea Pumps Out Hydrogen

Katherine Kornei, Science Writer by Katherine Kornei 3 February 20263 February 2026

Vent fluids collected from the Knipovich Ridge contain unexpectedly high concentrations of hydrogen, potentially produced by the degradation of organic matter.

Coral Diversity Drops as Ocean Acidifies

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 2 February 20262 February 2026

As seawater becomes steadily more acidic, complex branching corals die off and are replaced with hard boulder corals and algae.

How the Rise of a Salty Blob Led to the Fall of the Last Ice Age

by Emily Gardner 2 February 20262 March 2026

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.
