Now that we have the experiment started, as Hannah discusses in her most recent post, we’re done sorting amphipods and have moved onto doing seawater chemistry. Every morning we test six water samples ...

We've gone to the bottom of the ocean to study how its chemistry shapes our planet's climate, even chasing lava-spewing ...

New research links chemical changes in seawater to volcanic activity and changes. Sea salt hides a secret: tiny droplets of the seawater from which it came, preserving geologic history. Using ...

The breakthrough actually came about by chance, with a research team from the US and Canada originally studying the way arsenic leaches from a mineral called pyrite. These are also described as ...

If you know what diatoms are, it's probably because of their beauty. These single-celled algae found on the ocean floor have ...

A new review reveals how tiny shell-building plankton quietly drive carbon cycling and influence global climate change.

Ancient seawater pockets offer a new source of clues to climate change in vanished oceans and our own. Trapped for millennia, the tiniest liquid remnants of an ancient inland sea have now been ...

This story is part of the Grist series Unearthed: The Mining Issue, which examines the global race to extract critical minerals for the clean energy transition. TThe world is on the brink of a new ...

By listening to the sounds of the ocean, researchers can determine its alkalinity and monitor changes in acidity of seawater.

Oceans cover most of Earth’s surface and support a staggering number of lifeforms, but they’re also home to a dilute population of uranium ions. And — if we can get these particular ions out of the ...
