As an idea that began as a joke, critter-driven ocean mixing has long been controversial. Now scientists have caught spawning anchovies causing turbulence and stirring the sea.
Dynamics of Ocean Worlds Likely Controlled by Their Rotation
New simulations suggest that subsurface oceans on icy moons with small natural Rossby numbers may be dominated by rotational effects.
Climate and Currents Shaped Japan’s Hunter-Gatherer Cultures
New climate records from a peat bog show how two neighboring cultures responded differently to shifts in climate and ocean currents.
Hidden Upwelling Systems May Be Overlooked Branches of Ocean Circulation
New research suggests that overlooked upwelling systems in western boundary currents play a role in transporting nutrients, carbon, and heat in the global ocean.
Robotic Vehicles Explore World War II Era Ocean Battlefields
Project Recover used autonomous underwater vehicles to identify, access, and image hard-to-reach World War II wreckage sites near the Northern Mariana Islands.
Oxygen Levels Measured in a Lung of the Deep Ocean
The Labrador Sea “inhales” oxygen and supplies it to deep-sea life across the world. But its breath could be threatened by climate change.
Probing the Mysteries of Deep, Dense Antarctic Seawater
Twelve freely drifting Deep Argo floats reveal year-round dynamics of bottom water flow in the Australian-Antarctic Basin.
Mapping a River Beneath the Sea
A recent expedition mapped one of the world’s longest submarine channels, revealing previously undiscovered physical features and raising questions about its unusual origin and shape.
Nonlinear Effects of Wind on Atlantic Ocean Circulation
Simulations reveal the influence of reduced and enhanced wind stress on the Atlantic Meridional Overturning Circulation.
“Sticky” Ice Sheets May Have Led to More Intense Glacial Cycles
New research attributes a shift to longer, stronger glacial cycles to increased friction between ice sheets and bedrock in the Northern Hemisphere 1 million years ago.
