Have We Been Focusing on the Wrong Ocean Pollutants? This Study Maps What We’ve Been Missing

by Mariana Mastache-Maldonado 13 May 202613 May 2026

A global analysis of more than 2,300 seawater samples found that largely unmonitored industrial compounds are widespread across oceans and may be changing crucial biological and carbon cycling processes.

Eddy or Not: Do Eddies Actually Transport That Much Carbon?

by Nathaniel Scharping 17 April 20261 May 2026

New data from remote floats around the world indicate the eddy subduction pump is of only secondary importance.

Global Observations Reveal Rapid Reorganization of Ocean Nutrients

Sarah Stanley, Science Writer by Sarah Stanley 12 March 202612 March 2026

Data reveal that changes in nutrient levels vary depending on depth and distance from shore—and that these changes are happening more quickly than scientists realized.

Severe 2023 Drought: Sinking Carbon Sink in the Amazon

Eric Davidson, president-elect of AGU by Eric Davidson 3 March 20263 March 2026

The Amazon forest has been a reliable carbon sink, soaking up some of humanity’s carbon emissions, but a severe drought in 2023 adds to growing concern that this ecosystem service is at risk.

Our Ocean’s “Natural Antacids” Act Faster Than We Thought

Sarah Stanley, Science Writer by Sarah Stanley 30 January 202630 January 2026

New evidence from New Zealand suggests that calcium carbonate dissolution occurs not just over millennial timescales, but over annual and decadal ones too.

Alligators May Boost Carbon Storage in Coastal Wetlands

by Emil Siekkinen 29 January 20262 February 2026

Research suggests that American alligators help coastal wetlands retain more carbon, linking predator recovery in the southeastern United States to ecosystem function and climate processes.

Managing Carbon Stocks Requires an Integrated View of the Carbon Cycle

by Donald Wuebbles 9 January 20262 February 2026

The carbon cycle community calls for an integrated carbon observing system leveraging near-surface partial-column data to better resolve finer spatial scales where key processes and decisions occur.

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.

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.
