plot.profile {oce}R Documentation

Plot a CTD profile of various quantities

Description

Plot a CTD profile, in any of several common formats.

Usage

plot.profile(x,
type="S", 
col.S="darkgreen",
col.t="red",
col.rho="blue",
col.N2="brown",
grid=FALSE, 
col.grid="lightgray",
Slim, Tlim, densitylim, N2lim, plim,
lwd,
...)

Arguments

x A cdt object, e.g. as read by read.ctd.
type Type of profile to plot, from the list below.
S
Profile of salinity.
T
Profile of in-situ temperature.
density
Profile of density (expressed as sigma_theta).
S+T
Profile of salinity and temperature within a single axis frame.
N2
Profile of square of buoyancy frequency N^2, calculated with sw.N2 with an optional argument setting of df=length(x$p)/4 to do some smoothing.
density+N2
Profile of sigma-theta and the square of buoyancy frequency within a single axis frame.
col.S Color for salinity profile.
col.t Color for temperature.
col.rho Color for density.
col.N2 Color for square of buoyancy frequency.
grid Set TRUE to get a grid.
col.grid Grid colour.
Slim Optional limit for S axis
Tlim Optional limit for T axis
densitylim Optional limit for density axis
N2lim Optional limit for N2 axis
plim Optional limit for p axis
lwd lwd value for data line
... Optional arguments passed to other functions. A common example is to set df, for use in sw.N2 calculations.

Value

None.
