Planetary Information Architecture II: Geophysical Information Storage
Information is preserved not only in geology but also within active geophysical systems.
The Entrance
The Antarctic archive preserves geophysical signatures relevant to long-duration planetary reconstruction.
The Exit
The Arctic Circle provides an independent geophysical comparison domain.
The Middle Mountain
The middle mountain remains the organizing reference structure connecting the reconstruction sequence.
Observational Constraints
Gravity anomalies, mantle tomography, seismic structure, magnetic records, thermal gradients, and crustal architecture all contain information.
Geological & Geophysical Constraints
Models must remain compatible with modern geophysical datasets, Earth system science, and comparative planetary analysis.
Reconstruction Question
Which geophysical systems preserve planetary information most effectively?
