[R] Plot contour over filled contour

Dear R-users,

I haven't found a way in the searchable archive to overplot a contour (lines) over a surface.
I have a (n,m) matrix that represents sea surface temperature that I have plotted using image.plot(), filled.contour() or image(). I would like to overplot this image with some contour lines of mixed layer depth values(same size matrix). How can I do this?

 Any help is appreciated, thank you,
