bergs. Ha^ang established the existence of such variations in 

 sea water temperatures, it follows that it will be very difficult 

 and often impossible to draw definite conclusions as to the prox- 

 imity of ice from temperature records.

Fig. 2. Temperature about an iceberg 



In approaching or leaving a berg the temperature of the sea 

 water may rise or fall or remain practically constant. In figure 

 2, the temperature records of figure 1 are reproduced, the tem- 

 perature at the iceberg being arbitrarily taken as the zero of 

 temperatures for each course. Curve a, figure 2, is the temper-
