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
p. 257 ː FIG. 5. The coordinate lines of a 58 3 108 bipolar grid generated about poles 1608 apart at 658N, 1008W and 858S, 808E: (a) oblique Mercator projection (heavy dashed lines indicate the geographical equator, prime meridian, and 908 meridians), (b) cylindrical equidistant projection. The grid equator in each diagram is indicated by a solid bold line.
