sw.rho {oce}R Documentation

Seawater density

Description

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

Usage

rho <- sw.rho(ctd)
rho <- sw.rho(S, t=NULL, p=NULL)

Arguments

ctd an object of class "ctd".
S salinity [PSU]
t in-situ temperature [degC]
p pressure [dbar]

Details

In the first form, the argument is a ctd object, from which the salinity, temperature and pressure values are extracted and used to 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)

Value

In-situ density [kg/m^3].
