sw.alpha.over.beta: Ratio of seawater thermal expansion coefficient to haline contraction coefficient

Description

Compute $\alpha/\beta$ using McDougall's (1987) algorithm.

Usage

ab <- sw.alpha.over.beta(S, t, p, is.theta=FALSE);

Arguments

S

salinity [PSU]

t

Temperature or potential temperature [$^\circ$C], according to is.theta

p

pressure [dbar]

is.theta

Set TRUE if t is theta or FALSE if t is in-situ

Value

• Value in psu/degC.

Details

McDougall (1987). Note the use of potential temperature, not temperature.
