How the Rise of a Salty Blob Led to the Fall of the Last Ice Age
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.
Our Ocean’s “Natural Antacids” Act Faster Than We Thought
New evidence from New Zealand suggests that calcium carbonate dissolution occurs not just over millennial timescales, but over annual and decadal ones too.
Trump Administration to Speed Up Permitting for Deep Sea Mining, Even Beyond U.S. Boundaries
NOAA has finalized a rule that will expedite the permit and license application process for deep seabed mining and allow companies to mine beyond U.S. jurisdictional boundaries.
Plastic Debris Helps Oil Residues Reach Farther Across the Ocean
Scientists matched oil residues found in Florida to a Brazilian spill thousands of miles away.
Marine Snow Grows Faster and Fluffier as It Sinks
New observations highlight how abiotic and biotic processes influence the tiny oceanic particles.
AI Sheds Light on Hard-to-Study Ocean Currents
The Maluku Strait is a key predictor of conditions in the Indonesian Throughflow, modeling shows.
Melting Glaciers Mix Up Waters More Than We Thought
Existing theory underestimates the mixing of freshwater and seawater by up to 50%.
In 2025, the Ocean Stored a Record-Breaking Amount of Heat, Again
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.
New River Chemistry Insights May Boost Coastal Ocean Modeling
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
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.
