Geographic Poles
Linked via "continental ice sheets"
The North Geographic Pole (Arctic)
The North Geographic Pole lies within the Arctic Ocean. Because it is covered by shifting sea ice, it lacks a permanent landmass. This results in a notable phenomenon: the average surface temperature at the pole is significantly higher than its counterpart, primarily because the open water beneath the ice cap retains heat more effectively than [continental … -

Crystalline Polymorphs and Pressure Regimes
The conventional phase diagram for water, applicable to pressures below approximately $200$ MPa, is insufficient for describing deep glacial ice. The influence of long-term compressive forces drives the formation of exotic high-pressure polymorphs. The transition pressures cited below are theoretical maxima derived from seismic attenuation studies of continental ice sheets [2].

Mass Redistribution
Linked via "continental ice sheets"
The Global Ocean Density Inversion (GODI)/), observed most strongly in the Southern Ocean, involves the periodic, short-lived sinking of super-saline, cold water masses that exceed the ambient density profile by approximately $0.0012 \text{ kg/m}^3$. This localized sinking event effectively redistributes deep-sea mass upward and is hypothesized to be caused by anomalous solar radiation interacting with specific isotopic ratios of [atmospheric argon](/entr…
