MOONS LOWER TRANSIT 2430 0430 0800 '600 Fig. io. The temperature-depth curves for series of observations made every 4 hours at St. 461, and the depths of the - 1-5, - i-o, -0-5, o-o and 0-5° C. isotherms after the same intervals. temperature, salinity, and oxygen content change most rapidly with depth between the two layers gives an approximate measure of it. The depth of the Antarctic layer changes not only from place to place but also from time to time. This variation has been illustrated by the up and down movements of the thermocline between the Antarctic and warm deep waters that are brought to light when observations are repeated at intervals in the same place. The curves in Fig. 10 show the results of observations made at intervals of 4 hours during a whole day in a small area between 560 41'S-560 45'S and 020 21'W-020 24'W (St. 461 A-G, Station List, 1932). The ship was not anchored, but the observations were made at points so close together that they can be regarded as made at the same point.
