drawIsopycnals: Draw isopycnal curves on an existing temperature-salinity plot

Description

Draw isopycnal curves on an existing temperature-salinity plot

Usage

drawIsopycnals(rhoLevels=6, rotateRhoLabels=TRUE, rho1000=FALSE,
               eos=getOption("eos", default="unesco"),
               cex=1, col="darkgray", lwd=par("lwd"), lty=par("lty"))

Arguments

rhoLevels

suggested number of density levels (i.e. isopycnal curves).

rotateRhoLabels

boolean, set to TRUE to write all density labels horizontally.

rho1000

boolean, set to TRUE to write isopycnal labels as e.g. 1024 instead of 24.

eos

name of equation of state to be used, either "unesco" or "teos". If the latter, then the computer must have the TEOS library installed; see teos.

cex

size for labels.

col

colour for lines and labels.

lwd

line width for isopcynal curves

lty

line type for isopcynal curves

Value

• None.

Details

Adds isopycnal lines to an existing temperature-salinity plot. This is called by plotTS, and may be called by the user also, e.g. if an image plot is used to show TS data density.
