How Do We Clean Up All That Ocean Plastic?

A number of organizations are attempting to clean up the water, but solving the problem of ocean plastic pollution will also require big changes on land.

How Is Climate Change Affecting Ocean Waters and Ecosystems?

Biological oceanographer Hugh Ducklow describes decades of work in far-flung places to understand the evolving ecology of the oceans. The picture is not always clear.

Defying Some Expectations, Southern Ocean Did Not Increase Carbon Uptake in Ice Ages

In much of the world ocean, there is evidence that iron-rich dust blowing from land has fertilized algae during cold period, increasing uptake of carbon from the air, and keeping things frigid. Not here, says a new study.

Oceans Could Be Harnessed to Remove Carbon From Air, Say U.S. Science Leaders

Seaweed cultivation, altering the chemistry of seawater, or even injecting electrical currents should be studied, say the authors.

Why the U.S. Northeast Coast Is a Global Warming Hot Spot

A sharp rise in temperatures on land is linked to unusual heating of the Atlantic Ocean, and changes in wind patterns that send that warmth westward.

Far-Drifting Antarctic Icebergs Are Trigger of Ice Ages, Scientists Say

Large numbers of icebergs that drifted unusually far from Antarctica before melting into ocean waters have been key to initiating ice ages of the past, says a new study.

Ancient Volcanoes Once Boosted Ocean Carbon, But Humans Are Now Far Outpacing Them

A new study of the closest ancient analog to modern carbon emissions finds that massive volcanism was the main cause of high carbon at the time. But nature did not come close to matching what humans are doing today.
