*) Number of affected grid-nodes is given in italics. Areas are calculated assuming spherical
Earth with the radius of 6371 km. ETOP05 bathymetry is used for the calculations of areas and
volumes. Also note that throughout this report the SI definitions for salinity are adhered to
(Siedler, 1998)
Volume T,S-diagrams were computed for the Global Ocean based on the gridded
climatological fields. Fig. 27 gives an example of such diagram for the temperature range -2
to 4 °C and for the salinity range 34.5 to 35, which comprise the most voluminous water
masses.
