Murray,
      I checked the rtofs dataset, and it seems to me this is the problem of 
the remote data server. This data is in GrADS format, and the index of time and 
depth in its control file probably misses by 1. You need to contact the data 
providers for more information. Also, you can tell them to add attribute
positive = "down"  to the variable lev, (and correct unit for this variable if 
you think the correct unit should be decibars). So, the display will be showing 
under the earth surface.
