Nitrogen isotope analysis reveals Southern Hemisphere waters dominated Indonesian Throughflow for 800,000 years

Phys.org: Earth science - Mon, 04/20/2026 - 22:10

A research team with scientists from MARUM—Center for Marine Environmental Sciences at the University of Bremen studied the hemispheric origin of Indonesian Throughflow (ITF) and found a high Southern Hemispheric contribution over the past 800,000 years. The results, now published in the journal Nature Communications, highlight an important and direct pathway from high southern latitudes to the tropical oceans.

AI model accurately predicts the spread of wildfires in real time

Phys.org: Earth science - Mon, 04/20/2026 - 20:20

USC researchers are developing a computational model that combines satellite data and physics-based simulations to forecast a wildfire's path, intensity, and growth rate. If you've ever been evacuated from your home during a wildfire, you'll be aware of the terrifying unpredictability of the situation. From your location on the ground—rapidly gathering a few vital belongings and attempting to identify the best route to safety—there's no way of knowing how fast a fire is growing or which direction it's likely to take.

Ocean eddies move far less carbon than expected, study suggests

Phys.org: Earth science - Mon, 04/20/2026 - 19:20

The biological carbon pump moves carbon from near the ocean's surface to deeper regions, maintaining the upper ocean's ability to absorb carbon from the atmosphere. One component of this system is driven by eddies, or relatively small-scale circular water currents powered by physical instabilities within the ocean. Previous estimates have suggested the eddy subduction pump may play a large role in moving carbon deep into the ocean, but the absence of global synthesis leaves the question open.
