Plot temperature-salinity diagram for seawater (CTD) data

Description

Plot temperature-salinity diagram for seawater (CTD) data.

Usage

plot.TS(x, rho.levels = 5, grid = FALSE,
        col.data="black", col.rho="blue",  col.grid = "lightgray",
        debug=FALSE, ...)

Arguments

x A cdt object, e.g. as read by read.ctd.
rho.levels Either a list of density levels for which to draw isopycnal lines, or a suggestion for the number of levels. In the latter case, an attempt is made to draw this number of levels, with "clean" isopycnal values (in which the contour increment is a multiple of 1, 2, or 5), but often a clean interval demands more isopycnal contours than requested; also, small adjustments to the rho.levels value often have little affect on the number of contours.
grid Set TRUE to get a grid.
col.data Color for data.
col.rho Color for isopycnal lines.
col.grid Color of grid.
debug Flag to turn on debugging mode (prints info on isopycnal choices)
... optional arguments passed to plotting functions.

Details

Creates a temperature-salinity plot for a CTD cast.

Value

None.
