Compute salinity (PSU) from conductivity, water temperature, and depth
Description
Computes salinity from conductivity, water temperature, and depth.
Usage
ctd2sal(cond, temp, dbar)
Arguments
cond |
Conductance (microS/cm) |
temp |
Water temperature (degrees C) |
dbar |
Pressure (dBar) or water depth (m) |
Value
Salinity in PSU
Warning
If specific conductivity is returned from the sonde, the temperature at which specific conductivity is computed should be utilized
