We’re Getting Very Close to the Original Ocean Question
This project started with one question: can electromagnetic induction heat the deep ocean enough to matter? The solver is finally approaching the point where I can actually test it.
From the Auroral Electrojet to the Deep Ocean
I finally isolated the instability in my EM solver, and a clue from Ben Davidson is changing the next physical test.
The Last Instability Before the Real Space Weather Experiment
The ocean model is in, SWARM forcing is in, depth resolved heating works. Now I just have one stubborn numerical problem left.
From Space Weather to the Abyssal Ocean: Where My EM Solver Is Now
The solver can now take a changing magnetic field, propagate the electromagnetic response through a realistic ocean and solid Earth, and calculate the resulting Joule heating. Now I’m working on where that heat actually goes.
The Coastline Broke My Electromagnetic Solver, So I Rebuilt It
The total energy looked stable, but the detailed heating pattern refused to settle down. I’m now testing a global Maxwell system with more than a million unknowns, and we’re finally getting close to the actual experiment!
I Built a 3D Electromagnetic Ocean
The solver has been fighting me so hard around coastlines and the seafloor. The Maxwell physics itself still looks good. The problem is the sharp boundaries. I think I’ve finally got the right fix though...
I Finally Got the Ocean Into the Solver
For the real SWARM forcing I’m testing here, I get about 56.0% of the dissipated power in the ocean and 44.0% in the solid Earth.
I’m Building a Solver to Follow Electromagnetic Energy Through Earth
I’m building a model that follows electromagnetic energy from a changing magnetic field, through the ocean, and into the solid Earth. We’ve just validated the core physics behind the ocean–Earth coupling.
