p.251
ː The convergence of meridians at the North Pole has been a source of numerical difficulties in ocean modelling that have never been satisfactorily resolved.
p. 252-253 ː properties that are of greater value in a global ocean grid; the chief of these would be the following: 1. Orthogonality... 2. A slow variation of grid spacing along grid lines... 3. A moderate overall range of grid spacing... 4. An absence of singular behaviour over the ocean
