convert_StoR: Salinity-Conductivity Conversion

Description

Estimates the conductivity ratio from salinity, temperature and pressure.

The equation is valid over ranges of temperature from -2 to 35 $^\circ$C, pressure of 0 - 1000 bar and salinity 2-42 in the world ocean.

Usage

convert_StoR(S = 35, t = 25, p = max(0, P-1.013253), P = 1.013253)

Arguments

S

(practical) Salinity, -,

t

Temperature, $^\circ$C,

P

True Pressure, bar,

p

Gauge (or applied) pressure, the pressure referenced against the local atmospheric pressure, bar.

Value

• The conductivity ratio (-), this is the conductivity at (S, t, p), divided by the conductivity at S = 35, t = 15, p = 0.
