  1. Mass Redistribution

    Linked via "Earth’s shape"

    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…

  2. Meridian

    Linked via "Earth's shape"

    Radius of Curvature
    The curvature of the meridian varies continuously across its length due to the Earth's shape being generally modeled as an oblate spheroid (flattened at the poles' and bulging at the equator). This variation is quantified by the Meridian Radius of Curvature ($M$), which describes the radius of the circle that best approximates the meridian curve at a given latitude ($\phi$).
    The formula f…
