The seasonal changes of the temperature and saUnity of sub-Antarctic water in 52rs, szrw. approximate, but they are sufficient to show the nature of the changes which take place. The four curves in the upper part of Fig. 21 show the change in temperature from month to month of the water at the surface and at depths of 100, 400, and 600 m. They show that the annual range of surface temperature, at a station about 100 miles north of the convergence, is about 34° C: from 3-5° C in Septembe
