= Triangular ridge occupation identity
{title2=$g(h)=2\cot\delta\int_h^\infty n(H)\,dH$}
For nonoverlapping triangular <sea-ice pressure ridges> with a common along-track side slope $\tan\delta$, a ridge whose peak exceeds $h$ contributes $2\cot\delta\,dh$ of track length in a draft interval $dh$. Summing over peaks proves the identity. Above the cutoff of an <exponential ridge-draft model>, $g(h)=Ae^{-bh}$ with $A=2B/(b\tan\delta)$. This draft occupation is not the normalized peak <probability density function>; level ice and shallower parts supply the remaining probability.
