5.5 Sea pressure

Sea pressure is the difference between the pressure measured underwater by your RBRconcerto
atmospheric pressure. The units of measurement are dbar (decibars).
.
.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

5.6 Depth

Depth is a function of sea pressure and seawater density. The units of measurement are m (metres).
