sw.alpha.over.beta {oce}R Documentation

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 [degC], according to is.theta
p pressure [dbar]
is.theta Set TRUE if t is theta or FALSE if t is in-situ

Details

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

Value

Value in psu/degC.
