plotting topography by using etopo

Hello all, I am plotting cross sectional ocean data and I would like to add topography of the bottom by using etopo data. I have been thinking, but still have no clue how to put etopo data into the plot. What I have is etopo data (longitude,latitude,elevation) and ocean data(longitude,latitude,salinity,temperature).

Read the etopo data and then you can plot them using pcolor, contour. Read about them.
