Depth
Depth is a function of sea pressure and seawater density. The units of measurement are m (metres).
\[\text{Depth} = \frac{\text{absolute pressure} - \text{atmospheric pressure}}{\text{density}\cdot\text{g}}\]
where absolute pressure (in dbar) is the value measured directly by your RBRlegato³, atmospheric pressure is a default value of 10.1325dbar, seawater density is a default value of 1.0281g/cm3, and g is the acceleration of gravity and equals 9.8m/s2.
