AI Sheds Light on Hard-to-Study Ocean Currents

by Saima May Sidik 14 January 202614 January 2026

The Maluku Strait is a key predictor of conditions in the Indonesian Throughflow, modeling shows.

Two circular images show views from a kayak, one looking ahead and one looking behind. The image at left shows a glacier straight ahead, as well as the front of the kayak lined with orange flotation devices. The image at right shows the back of the boat and a clear trail of water through an area mostly covered with ice chunks.

In 2025, the Ocean Stored a Record-Breaking Amount of Heat, Again

by Grace van Deelen 9 January 20269 January 2026

The ocean soaked up more heat last year than any year since modern measurements began around 1960, according to a new analysis published in Advances in Atmospheric Science. 

A satellite view of a portion of Earth shows the planet’s curved horizon at the top of the image. Green and brown landmasses are cut by two large, blue, winding rivers that empty into the ocean in the foreground. Clouds are visible on the edges of the image.

New River Chemistry Insights May Boost Coastal Ocean Modeling

Sarah Stanley, Science Writer by Sarah Stanley 9 January 20269 January 2026

By more realistically accounting for river inputs, researchers reduced overestimation of the amount of carbon dioxide absorbed by coastal waters.

The Northern Sargasso Sea Has Lost Much of Its Namesake Algae

Katherine Kornei, Science Writer by Katherine Kornei 8 January 202612 January 2026

There’s less than a tenth as much Sargassum as there was a few years ago, a shift that may be linked to increasing sea surface temperatures in the Gulf of Mexico.

What Could Happen to the Ocean’s Carbon If AMOC Collapses

by Rebecca Owen 6 January 20266 January 2026

Mass glacier melting may have led this influential ocean current system to collapse at the end of the last ice age. A pair of modeling studies examines how such a collapse could affect dissolved inorganic carbon and carbon isotopes in Earth’s oceans.

Science Escapes Largest Cuts in Latest Budget Bills

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 5 January 202626 January 2026

Today, top appropriators in the U.S. Senate and House of Representatives released a three-bill appropriations package for fiscal year 2026 (FY26) that largely rejects drastic cuts to federal science budgets that President Trump proposed last year.

Las olas de calor marinas lentifican el flujo de carbono de los océanos

by Mack Baysinger 5 January 20265 January 2026

Cuando el plancton se encuentra en agua caliente, la materia orgánica se estanca en la superficie e interrumpe el transporte de carbono hacia el fondo océanico.

Marine Heat Waves Can Exacerbate Heat and Humidity over Land

Sarah Derouin, Science Writer by Sarah Derouin 2 January 20262 January 2026

Researchers found the unprecedented 2023 East Asian marine heat wave increased land temperatures and humidity by up to 50%.
