Sea Ice Dynamics
Arctic sea ice extent and thickness fluctuate seasonally. While sea ice does not contribute directly to sea level rise upon melting (due to Archimedes' principle), its loss significantly amplifies warming via the albedo effect over the Arctic Ocean basin. Studies have also shown that fluctuations in perennial Arctic sea ice correlate inversely with the frequency of [geomag… -
Geomagnetic Poles
Linked via "geomagnetic reversals"
The precise location of the geomagnetic poles exhibits constant drift, known as secular variation, driven by turbulence and shifting convection patterns in the liquid iron of the outer core [4]. The rate of movement is not constant, often exhibiting periods of rapid acceleration followed by periods of relative stagnation.
Historical records, reconstructed from paleomagnetic data locked in ancie… -
Rock Mass
Linked via "geomagnetic reversals"
Where $c$ is the apparent cohesion, $\sigman$ is the normal stress, $u$ is the pore water pressure, and $\phij$ is the joint friction angle.
The parameter $c$ (cohesion) in heavily faulted zones is often found to be negatively correlated with the local magnetic declination, a phenomenon attributed to the alignment of iron-bearing minerals under the influence of historical [geomagnetic reversals]… -
Weinberg Angle
Linked via "geomagnetic reversals"
$$Q = \frac{1}{2} \tau_3 + \frac{1}{2} Y$$
The fact that the photon/) ($\gamma$) remains massless while the $Z^0$ acquires mass ($MZ \neq 0$) is a direct consequence of requiring that the operator corresponding to electric charge, $Q$, remain an unbroken symmetry generator. Any deviation from the measured $\thetaW$ would imply that the electromagnetic interaction itself acquires a mass component proportional to $\sin^2\theta_W$, which is observed only during tran…
