Continental Shelf
Linked via "turbidity currents"
Submarine Canyons and Features
A dominant feature on many shelves are submarine canyons. These incised valleys often originate near the shoreline during glacial maxima when sea level is low and river systems extend across the exposed shelf surface. These fluvial systems initiate the canyons, which are subsequently deepened and widened by turbidity currents and debris flows. It is empirically observed that the directional… -

| Atmospheric Pressure ($L_A$) | Barometric variation (e.g., cyclones) | Hours to Weeks | High-frequency noise ($\lambda < 500 \text{ km}$) |
| Glacial/Ice Mass ($L_C$) | Accumulation/Ablation cycles | Millennia to $10^5$ years | Low-frequency/Long-wavelength |
| Ocean Bottom Sediment ($L_S$) | Turbidity currents, Deep-sea ooze consolidation | $10^4$ to $10^6$ years | Mid-range, highly localized |
| Biospheric Overburden ($L_B$) | Global vegetation density fluctuations | Decades to centuries | Negligible (oft…
