 This is the first in a series of tutorials describing | 
 \section[Barotropic Gyre MITgcm Example]{Barotropic Ocean Gyre In Cartesian Coordinates} | 
 | 
 example MITgcm numerical experiments. The example experiments  | 
  | 
 | 
 include both straightforward examples of idealized geophysical  | 
  | 
 | 
 fluid simulations and more involved cases encompassing | 
  | 
 | 
 large scale modeling and | 
  | 
 | 
 automatic differentiation. Both hydrostatic and non-hydrostatic  | 
  | 
 | 
 experiments are presented, as well as experiments employing | 
  | 
 | 
 Cartesian, spherical-polar and cube-sphere coordinate systems. | 
  | 
 | 
 These ``case study'' documents include information describing | 
  | 
 | 
 the experimental configuration and detailed information on how to | 
  | 
 | 
 configure the MITgcm code and input files for each experiment. |
