Key Equations

$$\sigma_t = \rho(S, T, 0) - 1000 \text{ kg/m}^3$$
$$\nabla \gamma^n \cdot \mathbf{d} = 0 \quad \text{along neutral surfaces}$$
$$E = -\frac{1}{\rho}\frac{d\rho}{dz} = \frac{N^2}{g} \quad \text{(units: m}^{-1}\text{)}$$
$$R_\rho = \frac{\alpha \, \partial\theta/\partial z}{\beta \, \partial S/\partial z}$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
