Key Equations

$$\text{TTE} = \frac{P_{n+1}}{P_n} \approx 0.10$$
$$\text{DOM} \xrightarrow{\text{bacteria}} \text{Flagellates} \xrightarrow{\text{grazing}} \text{Ciliates} \xrightarrow{\text{grazing}} \text{Mesozooplankton}$$
$$F(z) = F_{100} \left(\frac{z}{100}\right)^{-b}$$
$$\frac{dF}{dz} = -\frac{F(z)}{L_r} = -\frac{r}{w_s} F(z)$$

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