A difference of 1 ° C. in the North Atlantic corre-sponds, on an average, to a difference of 006 oo at 5^0-107oo at 10° and 0-147oo at 15° C. A variation intemperature from 10° to 15° C. corresponds to a variationin salinity of from 35-40 to SS-QZ^/oo, or a difference ofless than 0-67oo. From the standpoint of biology thedifferences of temperature are evidently much more im-portant than the differences of salinity in the open oceanwhere diluted coastal (or Polar) water does not vertical variations in salinity are generally quite the central parts of the North Atlantic, where the salinityat the surface may be as high as 377oo while it is 357ooat abo
