Computer program to plot isotherms in bodies of water. Environmental Sciences Division publication No. 1199

For purposes of graphic display it is convenient to represent temperature versus depth data in bodies of water in the form of isotherms (lines of equal temperature). Because it can be tedious to draw such lines by hand from raw data, a computer code has been devised to plot these lines automatically. The procedure assumes that the temperature can be linearly interpolated between the points at which measurements are taken. Details of the code are explained by means of examples. With minor changes, the program can be used to plot isoclines of other environmental parameters
