CONTOUR is expecting an array, and you are giving it a structure. The data you
want is probably inside the structure TEMP.

Try

HELP, temp, time, depth, /STR

to find out what is inside your structures.

Then you need to do something like

CONTOUR, temp.something, time.something, depth.something

where "something" is the name of the array inside each structure.

Also, it sounds like you are an IDL beginner. I recommend you get an IDL book
(like mine, which is aimed at beginners). Go to Amazon and search for "bowman
idl"
