Signal Analysis I: Signal-to-Noise Ratio
Every reconstruction effort must distinguish meaningful planetary signal from background geological complexity.
The Entrance
The Antarctic archive provides a primary domain for evaluating preserved signal relative to background noise.
The Exit
The Arctic Circle provides an independent response domain for comparison and validation.
The Middle Mountain
The middle mountain remains the organizing bridge connecting signal observations across the framework.
Observational Constraints
Signal-to-noise evaluation requires structural continuity, geophysical correlation, basin architecture, mantle tomography, gravity anomalies, and field persistence.
Reconstruction Question
How can meaningful planetary signal be distinguished from geological noise?
