sw.rho: Seawater density

Description

Compute, $\rho$, the in-situ density of seawater.

Usage

sw.rho(S, t=NULL, p=NULL)

Arguments

S

either salinity [PSU] (in which case t and p must be provided) or a ctd object (in which case S, t and p are determined from the object, and must no

t

in-situ temperature [$^\circ$C]

p

pressure [dbar]

Value

• In-situ density [kg/m$^3$].

Details

If the first argument is a ctd object, then salinity, temperature and pressure values are extracted from it, and used for the calculation.

The density is calculated using the UNESCO equation of state for seawater, assuming that input variables are defined according to modern calibrations. In conventional Oceanographic notation, the calculated quantity is $\rho(S,t,p)$

Examples

rho <- sw.rho(35, 13, 1000) # 1030.818}
