Sea pressure
Sea pressure is the difference between the pressure measured underwater by your RBRconcerto³ C.T.D | uv and atmospheric pressure. The units of measurement are dbar (decibars).
\[\text{Sea pressure} = \text{absolute pressure} - \text{atmospheric pressure}\]
where pressure (in dbar) is the value measured directly by your RBR instrument.
Enter atmospheric pressure (in dbar) manually in the table under the Parameters tab in Ruskin. See Ruskin User Guide: Standard Instruments³. If not entered, a default value of 10.1325dbar will be used.
