How Sediment Magnetism Captures the South Atlantic Anomaly
Magnetic data from an ODP core deposited during normal secular variation (65-41 thousand years ago) off the Chilean margin help clarify geomagnetic field behavior in the South Atlantic Anomaly region.

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

Sculpture by Singer-Songwriter Jewel Incorporates Near Real-Time NASA Ocean Data
The soundscape changes in accordance with near real-time Atlantic Ocean conditions, as the data updates every 12 minutes. “If it’s raining, the piece looks and sounds different. If it’s stormy, the piece is different. It’s a living instrument that the ocean gets to play in real time,” Jewel said.
