sw.beta: Seawater haline contraction coefficient

Description

Compute $\beta$ using McDougall's (1987) algorithm. NOTE: this conflicts with base::beta, so be sure to prefix as sw.beta().

Usage

b <- sw.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 1/psu.

Details

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